Most of the commenters and the creator are missing a few things/points. 1) I use it for portraits too and non-moving subjects I do not shoot sports or wildlife. If I pose a group or family for a portrait, I place the focus where I want it and then with the camera in a tripod I can shoot away and work on getting good expressions instead of making sure I get focus each time 2) regarding compromising handling of the camera, your left hand should be holding the weight of it not your right. The right hand is for button pushing not supporting the camera 3) night photography this is essential, especially when doing things like light painting in pitch dark conditions. The camera will not be able to focus. 4) macro, you can use BBF and AF-C or continuous focus. That would work. 5) I shoot wide opened too. Don't have a problem using BBF for that either.
Your points are valid; to each their own. Having said that, following are reasons I use BBF exclusively: 1. My camera's AF sucks... slow and struggling 2. I do a lot of AF-lock and re-compose types of photos 3. I do a lot of AF-lock, compose, then wait for the right moment types of photos 4. I don't shoot in wide aperture most of the times 5. My camera's AF sucks... yes, it's that bad that I need to say it twice. Oh, how I miss the snap focus feature of Ricoh GR series.
I've tried back button focus countless times on all manner of cameras as people constantly keep going on about how amazing it is, I don't like it at all! For action shots, I find it far more helpful to leave the camera in servo AF and assign a button to turn the AF off when held down if I really need it. Works a treat for me and far better than back button focus ever did.
@@robinwong valid arguments for your style of photography and your reasons why you do not use it are very fairly put. I do use bbf but have no argument with the reasons some (many?) photogs. do not use it.
Hi Robin. Thank you for your perspective, very interesting. My main benefit from BBF is when I have constant auto focus switched on. So when my thumb is held on the BBF button, then the camera focus is adjusting until I’m ready to shoot. That’s useful when my subject is moving. Once I remove my thumb, then the focus locks and that saves me re-focussing when my subject is static and I want several shots. BBF is easy to use on EM2i but it is really awkward on my EM10iii. The programmable button is not in an optimum position. A disadvantage of BBF you can add to your list, is when you hand your camera to a friend and have to explain how to focus. That’s something I dislike, so much so, that I may set up my EM10iii without BBF, for that reason alone.
Thanks for sharing your experience, and I appreciate that you mention the difference between E-m1 Mark II and E-M10 Mark III. About sharing camera... I don't usually share mine! Don't touch my camera!
Firstly I laughed, having watched Matti's video yesterday. It is fun to have both points of view. For me, I have tried back button focussing but so far I haven't warmed to it. Focus locking is possible without back button focussing, maybe that is the compromise as you can do that just when you need it.
Matti is an amazing friend, I learned so much from him. I just have to make this response video. I hope I made it clear enough that there is no right and wrong, just personal preferences.
I have found that back button focusing works better with certain cameras than others. I never use it with mirrorless cameras, but with some dslrs like Canon 5D III and Pentax K1 I think it works well, both ergonomically and from a results point of view. But since it depends a lot on what you are shooting, it is good to set it to one of the custom settings on the mode dial so you can quickly turn it on or off. Thank you for another great video!
Hey Robin. Finally a pro respected photographer who doesn’t use back button focus. I tried it many times and hated back button focus. My first point was why use two triggers for one shot. And secondly back button focus just never felt right. Thanks and keep up the good work.
I started off drinking the bbf cool aid when I got my first Nikon dslr. Went to shoot at an aquarium over a year ago & left home with a monster cramp! Over half of my shots came out blurry. Your video makes complete sense. Now I shoot exclusively with shutter button focus & Aputure Priority. Gotta say ive had alot more keepers since then! Amazing how Technique can make all the difference in not only photography but in any other profession like boxing, arts, race car driving & cooking food. Thanks for sharing your experiences! How you extend your arms & hands can act like a gimbal! Anytime you release your firm grip slow shutter speeds can amplify those slight twitches. OIS/IBIS can help but maintaining grip goes along way to increase your keeper rate!
There is another big reason which you did not even mention: sometimes I give my camera to another person (like my wife or even a stranger) to make a photo from me (or me and my wife). In such situations those people are not used to your camera at all; just imagine to explain them that the focusing is working completely different and they have to push a separate button...
Exactly!! I ran into that problem so often. I found that setting the camera to intelligent auto in that case does revert to shutter AF. But then it overrides any manual settings you may have set.
@@robinwong but if you want a photo of yourself when out and about you HAVE to let someone touch your camera. I quite often shoot people with a promise to send them the shot. Sometimes they return the favour. Last time this happened, the person was using a low end Canon DSLR in JPEG mode and while the shot was nicely framed, the sky was totally blown out. I should have handed over my wonderful E-M1 ii which was already adjusted for the cloudy/bright sky
I just came across this because I picked up a G9II in the trade in deal, and follow from a video he commented on about this. Anyway, I lend my Nikon for this reason all the time, and it takes around 5 seconds to explain to someone that they use the button called AF on to turn on the AF. I have literally never had any trouble with someone not getting it immediately.
You have valid points, Robin. I, however, use BBF for professional work and would not trade it for the world. As a portrait photographer, the BBF is very useful as you stay at one distance and do not have to refocus every time you press the shutter. Subject can move within the same distance for different poses, I'm on a tripod. I've recently started using continuous AF and for that, the shutter button AF works great in my opinion. BBF also is very useful for landscapes or if you want to do a panorama or a big file for portraits made with multiple shots. Enjoyed your video and tips. Gonna use them for my old E-M5. Thanks!
@@robinwong, Of course, my friend. It all comes to preference and/or your style of shooting. Fortunately, we can use either one with a switch of a button. Thanks again!
I actually use both methods depending on what I'm shooting. For wildlife I find back button really helps. For landscape, architecture, street, I use normal shutter. Both modes programmed as custom on my g9 so easy to flip between.
Hi Robin, exactly the same for me. Your friend Matti said in some cases it is not necessary that the camera focuses every time you press the shutter button. This is absolutely right. On the e-m1 it is possible to keep the shutter Button half pressed between the shots and maintain the focus you achieved before the first shot. I love this feature so much and I use it very often. For sure other Olympus cameras are also able to do it. It needs only a little practice to perform it, and for me it makes bbf completely obsolete. Btw, your Videos are very informative, and I love Your pictures, they are stunning. Thank you.
I moved from Canon 7D to Olympus OM-1 Mark 1 - and when i first got it, I was all about setting up BBF but after a while, i realized that the experience on that smaller body was not comfortable at all, like you mentioned. With more advanced AI auto focus, I think BBF’s days are numbered. The points you make about the comfortable grip, and delay between are def noticed coming from a full size DSLR with APS-C sensors. The canon had the button right under the thumb and you could hit it without breaking your grip. So I agree with your reasons and I’m realizing the same thing.
I was watching the other as the notification for this came in. I use BBF almost all the time. I am most familiar with Canon's implementation. If I did wedding photography, I would be happy using it. I would use focus tracking, when you press the AF-ON button, the camera acquires focus. While it's held down, the camera holds focus. When you , there is no pause to acquire focus, it's already done. If you want a burst, you can do that, pause, shoot another burst. Good for action sports, I don't see a downside for weddings. Your cramping sounds to me to be specific to one camera.
Nope. Cramping happens in a few cameras I tried in my earlier days of using DSLR. Not going to name brands now since whatever I say people will use against me since I am now an ambassador for Olympus. But you get the idea. Look at some other comments, I am not alone in this.
I understand what you are saying and I can see your point on your camera. Fortunately on my camera I don't have to move the position of my thumb with BBF on or off. My grip is the same as with the traditional focus Like others have mention I use it in continuous focus and lift the tip of my thumb a millimeter if I want to simulate single focus. I actually find I'm more stable taking shots as I don't have to feel and wait for the spot between getting focus and then fully pressing the shutter button to take the shot. I have focus already locked iin and it is one smooth motion to activate the shutter. Pausing on the shutter button to acquire focus causes me to apply uneven pressure to the camera body during a shot leading to more camera motion. The ergonomics of my camera seem to be better suited for BBF focusing. I'll have to keep this in mind if I move to another camera body. I don't want to give BBF up! Like you said what works for you. Great video!
Sure, if BBF works for you, continue using it. As long as you don't look at other photographers who don't use it like they are alien or something, it is fine.
Your video resonates very much with me. I actually tried BBF for some time (at the advise of my dad) before reverting to normal focusing. Using BBF focusing is tiring for events. But the main reason I moved away from BBF is due to how the Image Stabilization works in Olympus camera. I discovered that the IBIS kicks in the moment focus is locked, and not when exposure is locked. This means that any delay taking the picture after locking focus reduces / negates the benefit of IS. So whenever I need the IS to work (which is rather common), I just use the regular focus half-press.
Yeah, using the regular half-press will help stabilize your image while you are composing it, so it is helping when using longer lenses or shooting extreme close ups.
@@hautehussey That's my own conclusion after many times of usage. You can test it with the following method: 1. Use a fixed prime lens, say Panasonic 25mm f1.7. 2. Find out the slowest comfortable shutter speed you can take with it. For me, it was around 1 second for the Pana 25mm. 3. Focus lock it, using shutter half-press. 4a. Take a picture immediately. 4b. Hold onto the focus lock for 3 second before taking the picture. In all cases, my keeper rate on 4a is significantly higher than 4b. With 4b, after 3 to 5 seconds on focus lock, the camera is working as though there is no IBIS. So this brings me to my point on BBF. The delay using BBF is greater between the focus lock and shutter, and there is the shake introduced by using 2 different buttons as well.
ZD Leong the delay isn’t greater, because you’re using continuous auto focus when you use back button focus, and you don’t have to release the button at all! I think all of the people who have tried it and not liked it are using single AF with it, which negates most of the benefits of it.
I'm 100% with you Robin. I do mostly landscape photography and more often than not I use a remote to trigger the shutter. I have disabled that button completely.
Amen Robin! You've decribed it perfectly. I tried bbf and really tried to like it. But in the end it did not work for me. I am so much happier using the shutter button. This push toward bbf for everyone is nonsense.
I bought a second hand E-M1 Mk2 and wondered why the AF wasn't working - figured out previous owner set it up with BBF. Gave it a try but the rgonomics of seperate buttns to focus and shoot was awful. Thankfully a full reset got it all cleared out and set it the shutter button for the AF and exposure which works perfectly for my birding and fishing photography.
Wow! Excellent discussion with compelling points. I have heard many photographers claim that they use BBF “all the time,” and I think your points explain why this is unnecessary or even wise. I have found that I use the shutter focus most of the time ... until I’m in a situation where BBF works better. There is no reason to think there is only one way. Thanks for your very positively positioned “opposing” points.
Dear Robin, i completely agree with you, since i heard about the BBF technique i´ve trying to catch what was all the hype about, cause i didn´t see a real advantage in using that technique, even so after hearing the explanations from some of its users, but you have now listed in full detail all my concerns about it in your usual clear ways. Thanks
Long before this video, extensive experience accumulated from using multiple systems already told me that the movement of the thumb at the back gets in the way and hinders our getting the shots. Back in the very early days, around the time of F90X and EOS-5... There was this frustration that after you focused on the subject, the focus 'shift' after you recomposed. It was a time when most cameras had only 1 centre focus-point (some had 3, or 5) so it is natural to focus and recompose. Then Canon introduced the famous CF4 (Custom Function 4) which separated the focus from the shutter-release. It was a revelation! Recently I picked up an EOS-1 and intuitively, went straight to CF4 before I shoot. Nowadays people don't talk that way anymore (CF4) and would just say AF-On (or Back-Focus). Fast forward to present day. Especially with Mirrorless cameras, I do not find the AF-On (Back-Focus) essential. The placement of that 'AF-On' button is extremely crucial. Pick up the camera and hold it in the most natural position. If it is not comfortably under the thumb, you'd most likely loose shots you don't even know. Mirrorless changes the way photos are taken..
Hi Robin, interesting and valid points you bring up. I personally like back button focus. This brings up the next question: how do you focus? Do you use focus-re compose or do you move the focus point every time? How does that work for you in a 'fast' environment like street or wedding? I used to move the focus point around on my em5 with the 4 way d-pad but as I kept moving the focus point around accidentally by having the camera over my shoulder I have disabled the dpad. I had a lot of missed shots due to this. That lead to using the middle focus point and recompose, and finally back button focus. I found going into the super control panel and moving the focus point also a tedious task, so that's why I ended up with single point and back button focus
I move the focusing point every single time. I have a shortcut button to recenter the AF point quickly if needed. I don't believe in focus and recompose, that inroduces too much focusing error since I shoot wide open and close up shots a lot.
I agree with Robin 100%. I've tried BBF but went back to using AF shutter button. I only use BBF when I'm shooting sports and wildlife (birds mostly) as well.
Excellent arguments, Robin. I use BBF most of the time for the work I do, and it works very well for me. Most of the time though, I have a pretty big lens on my camera (typically the 4/3 35-100 f2), and I don’t rely on supporting the camera as much with my right hand. That frees up my thumb significantly. I do a lot of theatrical production photography, and that means shooting close to wide open most of the time. The AF that the camera selects is often counter to what I want, and BBF enables me to choose better, then recompose. I got close to 750 shots over a session of 90 minutes the other night, and found focus problems in less that 10% of them using BBF, much better than the 25-30% I get when I don’t use it. There are times when it isn’t appropriate at all, and it is a simple adjustment to not use BBF, but I do use it most of the time when I am using S-AF. I do use a lot of C-AF when shooting wildlife and birds, so it is easy for me to adapt to the situation.
Another reason why I don't use BBF - this technique only makes sense in continuous focus mode, which doesn't work with AF-assist beam of external flashlights. In low-light situations, the AF-assist beam from flashes is very useful at close to medium distances, whether you fire the flash or not. Instead of back button focus, I assign the back button to AF-lock, which means it locks focus as long as I keep pressing it. This gives me the flexibility to use the back button technique in the infrequent situations where I really need it.
Robin, I agree with you at all. If I tell how do my pictures and how i do or what elements from the camera I use, I cannot be applied in general for all photographers. Every Photographer has its own style, its own way to take pictures. I can not say if I use something from my EM 5 MI is the best and everybody must use in that way. Photography by definition is the way an artist is able to show his/her vision of the world by taking pictures.
Great job, Robin. I learn a great deal from both you and Joe Edelman, both of you Olympus Visionaries. I shoot Canon, but both of you make your teaching applicable to all photographers
I think it’s just a matter of the kind of photography it’s been taken. For C-AF mode I use BBF as it’s the best way for birds, animals, sports and aircraft photography. When shotting this kind of subjects you change the way you grab the camera, as you grab mainly the lens, long lens. For the other camera modes I use the traditional button for half-press/full-press and take picture. Nice video, as usual 😉
Also I find both your and Mattie's points absolutely valid. I have shutter button focus for all my standard modes and back button for my custom ones. That way I can quickly choose which one I need depending on the situation. Don't use BBF that often though.
I hear you Robin, in the 15 years that i have involved in digital photography and shooting many different subjects i have never used back button focusing for many of the same reasons you have spoke about.
Robin thank you for the video, I agree with your observations to a very large extent. I have over the years alternated from BBF to shutter focus and I have decided shutter focus and exposure is more practicable. At the point around 6min 20 sec you mention a delay between focus and pressing the shutter, I shoot mainly wildlife including macro and for 90% for the time I use Continuous AF, the reason being even when you are still or the subject is still one is almost inevitably not! So if you if you did use BBF and then pressed the shutter you would be in focus, I always pressed BBF before the shutter and kept it pressed as I pressed the shutter, the two actions can be simultaneous, therefore the likelihood of a correctly focused image is highest.
Never seen any use for the BBF, and the reasons are the same as yours. Started my photographing with system cameras in the beginning of 1970’s. And when the working autofocus came to dslrs I learned the SBF , used it since then.
I AGREEEEEEE! The ergonomics of "squeezing" is considered while designing a camera. I find that the back button is not perfectly placed for squeezing against the camera. This issue actually introduces camera shake in those moments that the shot happens quickly and I can't wait to take the picture. It places the "center of pivot" at the wrong position to ensure stability.
Good video, Robin, you made your point. Personally, I do love to use back button focus in all photo scenarios, like you said, it has become a second nature. However, I recently bought the Olympus OMD10 mark 2, and the button for back button focus is placed in such an inconvenient position! It's unbelievable!
I like setting a button for manual focus if I have to wait for a shot. The auto focus can get me there quick and the manual keep it there. Last night I was taking photos of children at a local carnival riding a small roller coaster. I set focus just after a peak in the ride so I could catch their hair in the air and the excitement in their faces. I didn't want auto focus to think I wanted another area in focus.
Since the days of " no auto focus" shooting film, we usually allowed for depth of field to help out and shot manual focus anyway. With this "built-in" history of muscle memory, it's pretty easy to move the focus clutch ring and shoot the same way - focus peaking is my best friend in this case........ You are correct though, it's always up to the individual to get accustomed to any shooting method.....
My first camera was Canon 5D Mark I, bought one used about one and a half year ago. Recently by recomendation from Tony & Chelsy I bought E-M10 Mark II as my travel and walk around camera. On 5D I used BBF all the time, when setting up my E-M10 i quickly qave up on BBF because of ergonomics, those cameras are definitely not designed for BBF. Having said that I love my tiny E-M10 and it's pancake kit lens.
Thanks Robin for explaining where back button focusing does not work. It is extremely important for people like me who are trying to improve taking photographing, to hear and know where to use and where not to use different focussing systems. Thanks for the Vedio
I use BBF for sports action and rarely otherwise. When shooting sports, there is usually a long lens on the camera and my left hand is supporting the weight of the camera and lens, so the right hand is only resting on the camera and using thumb for BFF and index for shutter is no strain at all. With a bigger camera/lens, I shoot with a monopod and the weight isn't really supported by either hand, so the same conditions apply for my right hand. Having said that, I have often used the shutter focus/release option in sports/action because of the much faster focus acquisition of recent cameras. When I got my first EM-5, I tested that fast focus quality in sports situations and was pretty amazed at how well it worked. As you say, it depends on how a person works and what they are shooting. I have not found it particularly useful in studio work, even though I sometimes use it there.
it is all preference in style of shooting, i do all being said without any issues, no hand cramp for hours, no out of focus on low F number, no shake/blur. Focus & recompose to shot many quickly with sharp photos. Fast moving object towards or away from you, back focus with AFC, takes sharp photos very quickly without need of burst mode. Some camera has half press shutter; that even faster response, all coupled into one better way of shooting fast , accurate & sharp - one back focus, AFC and half press shutter.
I use BBF as I mainly do wildlife photography. Coupled with C-AF focus moves with any camera or subject movement and it works just fine for me. I can press and release to lock focus and then press again as soon as there is any subject movement (like the example you give of waiting for a bird to take flight). And for macro I just keep the button pressed until I've released the shutter. Also the ergonomics of the EM1X puts the AFL button directly under my thumb and right next to the rear dial so there's hardly any movement of the thumb needed either to focus or to change settings. The main advantage for me of separating the shutter release from the AF is that I find BBF more precise than the half press of the shutter button (ie fewer accidental shots!) when reacting to sudden or fast subject movements. As you say it's an individual choice and whatever works best for you.
Good meaning friends have been convincing me to use back button focus. I personally feel that this method is not for me. I’m glad to know your reasons for not going back button focus. These reasons you mentioned align well with my thoughts about this subject. Thanks for sharing them.
Everyone has their own way of working, and that's okay. Some of the issues you mention seem to be related to using single-focus rather than continuous-focus. Also, it's possible to press the shutter button while also holding down the focus button, eliminating any delay between the 2. And the only other thing that could be changed is that using a battery grip may make the camera easier to hold. When I learned about Back Button Focus, I was using a Nikon D800, and that camera didn't identify subjects as well as the newer mirrorless cameras. I still use it, because there are times when I don't need to relock focus over and over again, such as when taking multiple exposures of a group of people, and it helps to reduce battery drain.
Robin, thank you for your point of view. A while back I started using back button focus on my EM1.2 and after a while I liked it. However I also use a EM5.2 and BBF does not work for that camera, so I end up going back and forth depending on the camera I am using. After your explanation of the way you use yours I may go back to just using the shutter button for both functions on both cameras. It will likely be easier and less confusing.
i like BBF, then again i use a camera where the ergonomics are set up for this and it makes a huge difference and i also leave it in C-AF, horse courses just use what works for you
i will agree with you on this. There may be a few cases where BBF would be a benefit, but not for my shooting styles. I do landscapes, architecture, and this last year really got into street photography -- all of which work best for me using the shutter button for focus.
I like this! Although I have used bbf for many years, this made me think it over again. In some situations I'm in trouble with bbf. It is always good to question things you do for time to time.
I thought you were joking when you commented on the other channel. I do a lot of action street photography and just find back button focusing annoying for me personally and agree with everything you said.
Some time ago when I came across the BBF video I believe it was Tony N. and I was surprised of how all this time I was taking great images without any problems, while Tony was explaining that I was doing it all wrong. You can do continuous AF I believe and have focus on subject until you press the shutter. I find that my normal AF works perfectly well.
Robin Wong there isn’t a way to set AEL when using back button focus on Olympus cameras, is there? I keep trying and it always triggers focusing instead...
There are times for it and times not for it, night is another one because you don't need to turn your AF off for focus up and shoot tripod shots, it's all a very personal thing and there are times it isn't so good, I just have a custom setting for BBF so I can easily switch it on and off without menu diving.
I like Matti & have watched a number of his videos having been introduced to him by PF (another superb Olympus Visionary) & as you say Robin, others like J Ellis are very knowledgable & accomplished photographers & yet Joseph in his opening statements states that he’s a people photographer, not wildlife & sports but advocates BBF. So unless I’m misunderstanding completely, he’s using it for exactly the reasons that you don’t ! Brilliant ! All i can say is how great full i am that you put this video together because for me, I’ve watched these guys & thought oh my gosh, this is another technique that i must learn to use if I’m to be a decent photographer! Well for now as least i can put it aside & don’t need to think about having to learn BBF. Don’t get me wrong, i love these guys & will continue to subscribe & i get why it works for them, but really helpful to see that you don’t use it & more importantly to explain why & in a respectful manner without having turned this into a BBF bashing video. You’re words were carefully chosen! Thanks Robin, see you next time!
I do landscape photography a lot and for me bbf works perfect,especially when i’m using nd filters for long exposure shots. For me disable autofocus on the lens everytime before putting on my nd filters on the lens was a pain in the butt,using bbf in that situation is much more easy’er and faster to use. Good video though, i agree that for macro and portraits bbf is not the way to go 🤔😉.
I use Canon and it does have its place, how ever, most people think they have to half press, get focus and then take the shot. In reality a straight press will focus and shoot in one press most of the time. Or BBF put it in servo mode to auto track. It depends on what your shooting. There is no right or no wrong. Just an opinion?
Late to the video, all really good valid points, but I wanted to add that most of the points that were said apply mostly to small cameras, I have used Canon, Fuji, Panasonic and Olympus, and most of the stuff you mention are present in the smaller cameras (Panasonic and Olympus mostly) but in the bigger ones (in my case Canon) the BBF is in the camera thumb rest, so it does not feels awkward or uncomfortable (at least to me), most of the time I shoot with Continous AF so the BBF is mostly necessary (In my experience)
I was using BBF buf stopped recently. One point about the thumb rest discussion and disturbing your grip of the camera - I had my BBF set up to use the front button usually set to be the preview function. One of my fingers naturally rests near this button anyway when gripping the EM5mk2. But I stopped using it because I found that for shots of stationary birds I prefer manual focus anyway and the BBF setting confuses me when I switch to other modes or when I get someone else to use my camera to photograph me I have to explain it to them.
With the Mark 111 - to use back button focus and keep balance you have to use a front button - the best one is the Preview Button- Please try it - It really works it might improve your performance.
Did you read all my other issues? While the handling is only one problem, reassigning the AF button to another location does not solve all other issues.
Interesting points really valid points both ways are very good. Just a preference There are a lot of soft people around complaining about how hard it is carrying a camera all day. It hurts my hands, neck etc I suppose we’re not all made the same Thanks for your video
I do a lot of wildlife photography but I still don't like back button focusing. Instead I'll use the back button to lock focus if I don't want the AF engaging. Normally I want it to refocus between shots because I'm trying to focus on an animal's eye and small subject movements or focusing errors can ruin the fixed focus shot.
Have tried BBF many times but like you it doesn’t suit the way I shoot. Even when I do bird photography I find no advantage. All good points. Thanks for posting.
BBF worked very good with DSLRs because of the different AF technology, however with mirrorless keeping AF-C all the time does not work with many lenses because the camera always hunts for focus so you never know whether you acquired the focus or not.
After watching this I've made a change on my G9. Your wright about the macro shooting being enhanced by only using one - the index finger for both focus & shutter release which reduces camera movement. Now, in my ' personal menu ' I've added ' Shutter AF ' so that I can quickly turn it on when shooting close-up / macro photos. Otherwise I prefer BBF. Thanks.
Thanks Robin for a well thought out and helpful video! I really appreciate your approach to photography and to sharing your insights and perspectives. You are very respectful of other options and the choices that other photographers make. I am grateful for that! I have never used BBF and I don't see a need to for the kind of photography that I do...mainly street. I also enjoy Matti Sulanto's channel and have also learned a lot from him. Please keep up the good work!
My preference is BBF but recently I have found a wildlife scenario that has me using shutter-button focussing. I've been trying Pro Capture Low hand held for getting shots of birds landing and leaving. I was having little success until I switched to SBF. I have now dedicated C3 on my EM1ii's mode dial to ProCapL with SBF.
Robin. Interesting topic which made me think about how I'm using my Oly cameras - I don't use BBF but how about FBF? From Matti's video I can understand that there are some times when you want a fixed focus, effectively leaving the focus in manual for a series of exposures. On the Panasonic bodies you have to move a selector but with the Oly bodies we can set up the Fn2 button for AF when the camera is in MF. Once the focus is set and the Fn2 button is released focus is locked and we can take as many exposures as we desire. This mode can be set as lever mode 2. Lever mode 1 can be your usual AF set-up. The only hassle with this is that in MF the AF framing indicator is not shown until you achieve AF lock. Y
Robin, I use BBF. For exposure I have to use center-weight metering. Is there a way to spot meter exposure when the exposure and focus area are not the same place?
I use half press and if I need refocus. Unless light is changing at a very fast pace I don't need back AEL button but if I need it it is there by default. I find no use for a separate focus button which forces me to use twice the muscles in my hands.
I agree that BBF feels a bit cumbersome. But I thought that an important advantage would be the separation of focus and exposure when you focus and recompose, especially with the focus point in the central position: if you use the half-press shutter button technique for locking focus, you also lock exposure and then when you recompose, the exposure for the frame may be off. Or is it the case that with Olympus cameras you can actually have a continuous (not locked) exposure evaluation even after having half-pressed the shutter button?
Using focus and recompose is quite dangerous for the kind of photography that I do. I will move the focusing point to where the subject is and make sure the focus is critically accurate.
@@robinwong Thank you for your reply, that's interesting. For me, I found that on the street there is often little time to move around the focus point when you spot something interesting happening.
I have short thumbs so BBF has never been comfortable to use for me. I tried assigning focus to a front button for a while but that was just adding another step for no good reason so I'm back to half press and go. I could see the advantage of using BBF for shooting birds in amongst tree branches where you don't want the camera to shift focus from the bird to the branches everytime you shoot, so I might use the FBF for that. They each have their uses :)
Having used back button focus on my DSLR I adopted it for the EM1 mk ii I purchased. Not sure if it’s the size of the Olympus but I did find that as mentioned by Robin that for me it made the camera less stable and more prone to unnecessary movement. Especially for close up shots. So, I am going to revert back to using the shutter release button for focus to see how it works.
Finally somebody says it. Moreover, Olympus mysteriously doesn't allow to remove AF and AE from the shutter button at the same time -- exactly what you want for recomposing and shooting panoramas.
I use BBF in CAF+tracking for wildlife etc, assigned to # 2 on my back switch, #1 is assigned to S-AF, simple and effective for me, have booth available since normal shutter function is in mode 1.
Good arguments! I stopped trying BBF years ago, it does not work for me. My thumb has better things to do, i.e. selecting focus points if needed. All the best with using shutter bottom, selecting cont. AF/ single shot AF/ manual focus due to genre, in continuous AF sometimes focus stop button instead of BBF all the time.
My thoughts exactly! Just too many steps, I am a miminalist, I want as little steps as possible before getting the shot. Using another finger drains too much brainpower!
I agree Robin, I've tried back button focus and found it more confusing. I just couldn't get used to it, it is way more intuitive to half press I couldn't find any advantage to back button focus. It was like trying to pat my head and rub my belly at the same time! :)
I tried it for a while, but it was difficult to get waist level (or lower angle) shots comfortably with back button focus. I sometimes take dog portraits where I have to get low to the ground. Shutter focus allows me to simply use my thumb on the shutter button to focus and shoot when I'm shooting from a very low angle, which is far easier on my wrist.
I use BBAF and photo birds in flight and pickleball often and it works for me. However you have made many valid points. I'll consider them in my other shooting.
I shoot birds and wildlife with my old Zuiko ED 300mm 2.8 + EC 20 2x teleconverter. I have never been able to get used to BBF with that gear as I've always felt lifting my thumb makes everything very unstable. Even with the EM-1 Mk2, I'm not very confident. Maybe with a tripod, it would be fine but hand held; it is definitely a No, No! Thanks Robin!
Rajesh, I shoot mainly sports and wildlife. For that I use a combination of BBAF (back button AF) and FBAF (Front button AF) and with the Nikon D850 or D500 it works very well for those venues. I program the back button for what I am planning to shoot most that day (i.e. if animal portraits single point AF, if BIF (Birds in Flight) then group AF. The front button is a different focus mode (i.e. if BBAF is single point, the front button would be group for BIF). That way, should unpredictable things happen as did today (with a Cara Cara plucking a seagull off the ground into mid air) I can quickly hit group AF and catch a wing or part of the bird for capture). All that said, it took practice, but is now very useful. I agree with Robin's point that this style doesn't fit all people, all cameras, all shooting styles, or all situations. Stating why you like something or don't is always helpful. Even though I shoot Nikon I follow Robin's channel and Joe's channel for Olympus. They have some pretty cool people using Olympus gear who do a nice job telling it like it is. Kudos.
I never find the back button is useful for focus, I set my back button to switch on MF. I have the amazing pro capture this and back button have no sens.
Good video with some valid points well explained and argued - but I'll stick with AF-C and back button focus when shooting handheld; it just suits me and my photography.
Late to the video, but one more point that was mentioned in a video by someone who also doesn't use BBF is that releasing the AF-ON button with your thumb before pressing the shutter button is very counterintuitive and, as you mentioned, it introduces unnecessary handling movement, and it introduces at least a little time gap between focus and release which can easily ruin macro shots. I *believe* I understand why many people prefer BBF, but I've tried it and it's definitely not suited for me or my shooting style. (Neither is using AF-C btw, I'm always on AF-S.)
I use back button focus because I find the shutter button, on my EM 1 mk 11, too sensitive . This results in photos being taken while I'm trying to focus. Each to their own.
BBF AF-lock is good for video shooting in Lumix cameras. It works like manual focus. No focus hunting in BBF. I prefer this nethod for video. But in photo shooting i use both as per scenereo.
Great video Robin, I have been using BBF and do like it even though I don't at times, I'll now switch back to normal and see how that goes, nice to have that option
My method for using BBF is to use it with continuous AF (AF-C), not single AF (AF-S). As long as you have your thumb on the AF-ON button the camera is auto focusing, you do not have to let go of the AF-ON button to press the shutter. When a camera has fast accurate AF-C, some do not, and is ergonomically designed for BBF, you can leave the camera set to AF-C and still have the instant choice of AF-C or AF-S by releasing or not the AF-ON button. Whatever method photographers use, if it works for you it is fine.
I use C-AF but I dont use BBF. It works and I have high keeper rates. I just don't get the need to keep pressing another button. And I need to securely grip the camera, I cannot imagine using any camera with just 3 fingers.
Another reason I don't like BBF: if using the battery grip (HLD-9), the AEL/AFL button is not really accessible in portrait orientation without reassigning the AEL/AFL button to F1. And to get the "natural" function of F1, you have to reassign button function to another button. Not worth the confusion IMO. And I agree, the half press and shoot seems faster.
Interesting argument on macro. I shoot a lot of macro with Olympus E-M1 II and the PEN-F, former with back button focus) and I really appreciate BBF for macro. But I use a different technique. I use either MF or S-AF with BBF, with autofocus only being used to get in the range of a shot, and then, with focus locked, I’ll subtly refocus with my body, at the nearest point of what I want in focus of the subject I’m shooting, and then I’ll either rock forward in a controlled movement and shoot a burst, or in magnified view will focus with my body and shoot when I have the subject in the desired focus. With the burst I can frequently stack some shots of even a moving subject to get more DoF. Coupling AF with the shutter I found I frequently failed to nail focus exactly where I wanted it on the eye. But, as you say, what matters in the end is what the photographer enjoys. And a video like this that encourages a photographer from a different perspective may be just the thing that helps them to find the solution they love. So thanks! And nice macro shots.
man, burst, rock back and forth, manual focus, those are a lot of steps! I just rely on S-AF, move my focusing point to the desired spot on the frame, half press shutter button and press down quickly after AF is acquired. works every time.
Robin Wong I’ve checked out your other video. I guess I should have specified that the manner of shooting I described is what I use when I’m working at very close focal ranges (e.g. the face of a wasp) where an autofocus box placed on the eye, for example, is unlikely to place the focal plane where needed, or when image stacking is desired. Or in more extreme examples such as shooting a snowflake (which can involve dozens of exposures in sequence). It is a method similar to what Don Komarechka uses. The method I described, for me, wouldn’t work reliably if shooting, for example, a bumble bee flying flower to flower. In those cases I tend to prefer a focusing method similar to what you’re describing here and would agree with your assessment. And I’d also agree, there, that back button focusing isn’t doing me any favors. S-AF would be my preference and pairing that with a back button and nailing the exposure with the shutter button introduces more lag and margin of error than would be the case if I paired it with the shutter button, and I feel like I get a bit fewer keepers with C-AF on the back button (though it has been decent for quickly-moving subjects like bumble bees).
Apart from the reasons you mention, Robin, there is an other factor that for me makes BBF a non-option. Like yourself I wear glasses (with rather thick lenses, as I'm far sighted). But I also have a left eye preference. So, when I'd use the camera's EVF, with the BBFmethod I'd have to wriggle my thumb between the right glass of my specs and the Focus button: how inconvenient! BTW I've also switched off touch screen: my nose will unintentionally activate focus (focus to the lower right corner of the image) while using the EVF. Moreover I mostly prefer to use the EVF, instead of the screen: to have a concentrated view of my subject, without distractions. PeterK
Most of the commenters and the creator are missing a few things/points.
1) I use it for portraits too and non-moving subjects I do not shoot sports or wildlife. If I pose a group or family for a portrait, I place the focus where I want it and then with the camera in a tripod I can shoot away and work on getting good expressions instead of making sure I get focus each time
2) regarding compromising handling of the camera, your left hand should be holding the weight of it not your right. The right hand is for button pushing not supporting the camera
3) night photography this is essential, especially when doing things like light painting in pitch dark conditions. The camera will not be able to focus.
4) macro, you can use BBF and AF-C or continuous focus. That would work.
5) I shoot wide opened too. Don't have a problem using BBF for that either.
Same here
Your points are valid; to each their own.
Having said that, following are reasons I use BBF exclusively:
1. My camera's AF sucks... slow and struggling
2. I do a lot of AF-lock and re-compose types of photos
3. I do a lot of AF-lock, compose, then wait for the right moment types of photos
4. I don't shoot in wide aperture most of the times
5. My camera's AF sucks... yes, it's that bad that I need to say it twice.
Oh, how I miss the snap focus feature of Ricoh GR series.
Ah but most cameras these days have extremely fast AF, so focusing should not an issue.
I've tried back button focus countless times on all manner of cameras as people constantly keep going on about how amazing it is, I don't like it at all! For action shots, I find it far more helpful to leave the camera in servo AF and assign a button to turn the AF off when held down if I really need it. Works a treat for me and far better than back button focus ever did.
Thanks for sharing your experience, glad that we are on the same page.
My first thought was like "WHATT!?!?!?!?" 😱 But after watching the entire video I see what you mean, Robin. Valid points to think about 👍
No worries, I am not against BBF, it just does not work for me.
@@robinwong valid arguments for your style of photography and your reasons why you do not use it are very fairly put. I do use bbf but have no argument with the reasons some (many?) photogs. do not use it.
Hi Robin.
Thank you for your perspective, very interesting.
My main benefit from BBF is when I have constant auto focus switched on. So when my thumb is held on the BBF button, then the camera focus is adjusting until I’m ready to shoot. That’s useful when my subject is moving. Once I remove my thumb, then the focus locks and that saves me re-focussing when my subject is static and I want several shots.
BBF is easy to use on EM2i but it is really awkward on my EM10iii. The programmable button is not in an optimum position.
A disadvantage of BBF you can add to your list, is when you hand your camera to a friend and have to explain how to focus. That’s something I dislike, so much so, that I may set up my EM10iii without BBF, for that reason alone.
Thanks for sharing your experience, and I appreciate that you mention the difference between E-m1 Mark II and E-M10 Mark III.
About sharing camera... I don't usually share mine! Don't touch my camera!
Firstly I laughed, having watched Matti's video yesterday. It is fun to have both points of view. For me, I have tried back button focussing but so far I haven't warmed to it. Focus locking is possible without back button focussing, maybe that is the compromise as you can do that just when you need it.
Matti is an amazing friend, I learned so much from him. I just have to make this response video. I hope I made it clear enough that there is no right and wrong, just personal preferences.
@@robinwong of course, it is fun to hear from both of you
I have found that back button focusing works better with certain cameras than others. I never use it with mirrorless cameras, but with some dslrs like Canon 5D III and Pentax K1 I think it works well, both ergonomically and from a results point of view. But since it depends a lot on what you are shooting, it is good to set it to one of the custom settings on the mode dial so you can quickly turn it on or off. Thank you for another great video!
Thanks, and yes, choose the method that works for you.
Hey Robin. Finally a pro respected photographer who doesn’t use back button focus. I tried it many times and hated back button focus. My first point was why use two triggers for one shot. And secondly back button focus just never felt right. Thanks and keep up the good work.
Thanks, and honestly, it does not matter whether we use BBF or not. We use what works best, and for me, not BBF
I started off drinking the bbf cool aid when I got my first Nikon dslr. Went to shoot at an aquarium over a year ago & left home with a monster cramp! Over half of my shots came out blurry. Your video makes complete sense. Now I shoot exclusively with shutter button focus & Aputure Priority. Gotta say ive had alot more keepers since then! Amazing how Technique can make all the difference in not only photography but in any other profession like boxing, arts, race car driving & cooking food. Thanks for sharing your experiences! How you extend your arms & hands can act like a gimbal! Anytime you release your firm grip slow shutter speeds can amplify those slight twitches. OIS/IBIS can help but maintaining grip goes along way to increase your keeper rate!
There is another big reason which you did not even mention: sometimes I give my camera to another person (like my wife or even a stranger) to make a photo from me (or me and my wife). In such situations those people are not used to your camera at all; just imagine to explain them that the focusing is working completely different and they have to push a separate button...
I don't share my camera! Don't touch it!
Exactly!! I ran into that problem so often. I found that setting the camera to intelligent auto in that case does revert to shutter AF. But then it overrides any manual settings you may have set.
@@robinwong but if you want a photo of yourself when out and about you HAVE to let someone touch your camera. I quite often shoot people with a promise to send them the shot. Sometimes they return the favour. Last time this happened, the person was using a low end Canon DSLR in JPEG mode and while the shot was nicely framed, the sky was totally blown out. I should have handed over my wonderful E-M1 ii which was already adjusted for the cloudy/bright sky
I just came across this because I picked up a G9II in the trade in deal, and follow from a video he commented on about this. Anyway, I lend my Nikon for this reason all the time, and it takes around 5 seconds to explain to someone that they use the button called AF on to turn on the AF. I have literally never had any trouble with someone not getting it immediately.
You have valid points, Robin. I, however, use BBF for professional work and would not trade it for the world. As a portrait photographer, the BBF is very useful as you stay at one distance and do not have to refocus every time you press the shutter. Subject can move within the same distance for different poses, I'm on a tripod. I've recently started using continuous AF and for that, the shutter button AF works great in my opinion. BBF also is very useful for landscapes or if you want to do a panorama or a big file for portraits made with multiple shots.
Enjoyed your video and tips. Gonna use them for my old E-M5. Thanks!
Good that you find the BBF working well for you. I cannot say the same for myself.
@@robinwong, Of course, my friend. It all comes to preference and/or your style of shooting. Fortunately, we can use either one with a switch of a button. Thanks again!
I'd say manual focus for landscapes is the best.
I actually use both methods depending on what I'm shooting. For wildlife I find back button really helps. For landscape, architecture, street, I use normal shutter. Both modes programmed as custom on my g9 so easy to flip between.
yeah choose the method that works best for you. no right or wrong.
Hi Robin, exactly the same for me. Your friend Matti said in some cases it is not necessary that the camera focuses every time you press the shutter button. This is absolutely right. On the e-m1 it is possible to keep the shutter Button half pressed between the shots and maintain the focus you achieved before the first shot. I love this feature so much and I use it very often. For sure other Olympus cameras are also able to do it. It needs only a little practice to perform it, and for me it makes bbf completely obsolete. Btw, your Videos are very informative, and I love Your pictures, they are stunning. Thank you.
I moved from Canon 7D to Olympus OM-1 Mark 1 - and when i first got it, I was all about setting up BBF but after a while, i realized that the experience on that smaller body was not comfortable at all, like you mentioned. With more advanced AI auto focus, I think BBF’s days are numbered. The points you make about the comfortable grip, and delay between are def noticed coming from a full size DSLR with APS-C sensors. The canon had the button right under the thumb and you could hit it without breaking your grip. So I agree with your reasons and I’m realizing the same thing.
I was watching the other as the notification for this came in. I use BBF almost all the time. I am most familiar with Canon's implementation. If I did wedding photography, I would be happy using it. I would use focus tracking, when you press the AF-ON button, the camera acquires focus. While it's held down, the camera holds focus. When you , there is no pause to acquire focus, it's already done. If you want a burst, you can do that, pause, shoot another burst. Good for action sports, I don't see a downside for weddings.
Your cramping sounds to me to be specific to one camera.
Nope. Cramping happens in a few cameras I tried in my earlier days of using DSLR. Not going to name brands now since whatever I say people will use against me since I am now an ambassador for Olympus. But you get the idea. Look at some other comments, I am not alone in this.
I understand what you are saying and I can see your point on your camera. Fortunately on my camera I don't have to move the position of my thumb with BBF on or off. My grip is the same as with the traditional focus Like others have mention I use it in continuous focus and lift the tip of my thumb a millimeter if I want to simulate single focus. I actually find I'm more stable taking shots as I don't have to feel and wait for the spot between getting focus and then fully pressing the shutter button to take the shot. I have focus already locked iin and it is one smooth motion to activate the shutter. Pausing on the shutter button to acquire focus causes me to apply uneven pressure to the camera body during a shot leading to more camera motion. The ergonomics of my camera seem to be better suited for BBF focusing. I'll have to keep this in mind if I move to another camera body. I don't want to give BBF up! Like you said what works for you. Great video!
Sure, if BBF works for you, continue using it. As long as you don't look at other photographers who don't use it like they are alien or something, it is fine.
I found BBF a pain for trying to shoot moving targets. When I'm using the 40-150 pro lens, I set the L-Fn button for focus lock when needed.
We are on the same page
Your video resonates very much with me. I actually tried BBF for some time (at the advise of my dad) before reverting to normal focusing. Using BBF focusing is tiring for events.
But the main reason I moved away from BBF is due to how the Image Stabilization works in Olympus camera. I discovered that the IBIS kicks in the moment focus is locked, and not when exposure is locked. This means that any delay taking the picture after locking focus reduces / negates the benefit of IS. So whenever I need the IS to work (which is rather common), I just use the regular focus half-press.
Yeah, using the regular half-press will help stabilize your image while you are composing it, so it is helping when using longer lenses or shooting extreme close ups.
ZD Leong it doesn’t make any sense that iBIS would work like that. I would research that theory.
@@hautehussey That's my own conclusion after many times of usage. You can test it with the following method:
1. Use a fixed prime lens, say Panasonic 25mm f1.7.
2. Find out the slowest comfortable shutter speed you can take with it. For me, it was around 1 second for the Pana 25mm.
3. Focus lock it, using shutter half-press.
4a. Take a picture immediately.
4b. Hold onto the focus lock for 3 second before taking the picture.
In all cases, my keeper rate on 4a is significantly higher than 4b. With 4b, after 3 to 5 seconds on focus lock, the camera is working as though there is no IBIS.
So this brings me to my point on BBF. The delay using BBF is greater between the focus lock and shutter, and there is the shake introduced by using 2 different buttons as well.
ZD Leong the delay isn’t greater, because you’re using continuous auto focus when you use back button focus, and you don’t have to release the button at all! I think all of the people who have tried it and not liked it are using single AF with it, which negates most of the benefits of it.
I'm 100% with you Robin. I do mostly landscape photography and more often than not I use a remote to trigger the shutter. I have disabled that button completely.
Thanks!
Amen Robin! You've decribed it perfectly. I tried bbf and really tried to like it. But in the end it did not work for me. I am so much happier using the shutter button. This push toward bbf for everyone is nonsense.
Exactly, I hope people can be more open minded when it comes to shooting styles and techniques.
I bought a second hand E-M1 Mk2 and wondered why the AF wasn't working - figured out previous owner set it up with BBF. Gave it a try but the rgonomics of seperate buttns to focus and shoot was awful. Thankfully a full reset got it all cleared out and set it the shutter button for the AF and exposure which works perfectly for my birding and fishing photography.
Wow! Excellent discussion with compelling points. I have heard many photographers claim that they use BBF “all the time,” and I think your points explain why this is unnecessary or even wise. I have found that I use the shutter focus most of the time ... until I’m in a situation where BBF works better. There is no reason to think there is only one way. Thanks for your very positively positioned “opposing” points.
No reason to use BBF indeed!
Dear Robin, i completely agree with you, since i heard about the BBF technique i´ve trying to catch what was all the hype about, cause i didn´t see a real advantage in using that technique, even so after hearing the explanations from some of its users, but you have now listed in full detail all my concerns about it in your usual clear ways. Thanks
Thanks for agreeing, and show of support!
Long before this video, extensive experience accumulated from using multiple systems already told me that the movement of the thumb at the back gets in the way and hinders our getting the shots.
Back in the very early days, around the time of F90X and EOS-5... There was this frustration that after you focused on the subject, the focus 'shift' after you recomposed. It was a time when most cameras had only 1 centre focus-point (some had 3, or 5) so it is natural to focus and recompose. Then Canon introduced the famous CF4 (Custom Function 4) which separated the focus from the shutter-release. It was a revelation! Recently I picked up an EOS-1 and intuitively, went straight to CF4 before I shoot. Nowadays people don't talk that way anymore (CF4) and would just say AF-On (or Back-Focus).
Fast forward to present day. Especially with Mirrorless cameras, I do not find the AF-On (Back-Focus) essential. The placement of that 'AF-On' button is extremely crucial. Pick up the camera and hold it in the most natural position. If it is not comfortably under the thumb, you'd most likely loose shots you don't even know.
Mirrorless changes the way photos are taken..
Hi Robin, interesting and valid points you bring up. I personally like back button focus. This brings up the next question: how do you focus? Do you use focus-re compose or do you move the focus point every time? How does that work for you in a 'fast' environment like street or wedding? I used to move the focus point around on my em5 with the 4 way d-pad but as I kept moving the focus point around accidentally by having the camera over my shoulder I have disabled the dpad. I had a lot of missed shots due to this. That lead to using the middle focus point and recompose, and finally back button focus. I found going into the super control panel and moving the focus point also a tedious task, so that's why I ended up with single point and back button focus
I move the focusing point every single time. I have a shortcut button to recenter the AF point quickly if needed. I don't believe in focus and recompose, that inroduces too much focusing error since I shoot wide open and close up shots a lot.
I agree with Robin 100%. I've tried BBF but went back to using AF shutter button. I only use BBF when I'm shooting sports and wildlife (birds mostly) as well.
Thanks for agreeing!
I agree - I have tried Back Button Focus several times over the years but it just seemed too awkward. I use focus and recomposes when needed!
Exactly, that was what I tried to say, BBF is not for every one.
Excellent arguments, Robin.
I use BBF most of the time for the work I do, and it works very well for me. Most of the time though, I have a pretty big lens on my camera (typically the 4/3 35-100 f2), and I don’t rely on supporting the camera as much with my right hand. That frees up my thumb significantly. I do a lot of theatrical production photography, and that means shooting close to wide open most of the time. The AF that the camera selects is often counter to what I want, and BBF enables me to choose better, then recompose.
I got close to 750 shots over a session of 90 minutes the other night, and found focus problems in less that 10% of them using BBF, much better than the 25-30% I get when I don’t use it. There are times when it isn’t appropriate at all, and it is a simple adjustment to not use BBF, but I do use it most of the time when I am using S-AF. I do use a lot of C-AF when shooting wildlife and birds, so it is easy for me to adapt to the situation.
Good that BBF works better for you, the end results matter.
Another reason why I don't use BBF - this technique only makes sense in continuous focus mode, which doesn't work with AF-assist beam of external flashlights. In low-light situations, the AF-assist beam from flashes is very useful at close to medium distances, whether you fire the flash or not.
Instead of back button focus, I assign the back button to AF-lock, which means it locks focus as long as I keep pressing it. This gives me the flexibility to use the back button technique in the infrequent situations where I really need it.
exactly, use it when you need it!
Robin, I agree with you at all. If I tell how do my pictures and how i do or what elements from the camera I use, I cannot be applied in general for all photographers. Every Photographer has its own style, its own way to take pictures. I can not say if I use something from my EM 5 MI is the best and everybody must use in that way. Photography by definition is the way an artist is able to show his/her vision of the world by taking pictures.
Exactly, we are all different.
Great job, Robin. I learn a great deal from both you and Joe Edelman, both of you Olympus Visionaries. I shoot Canon, but both of you make your teaching applicable to all photographers
Thanks for the compliments, appreciate it much. Will do more similar videos surely.
I think it’s just a matter of the kind of photography it’s been taken. For C-AF mode I use BBF as it’s the best way for birds, animals, sports and aircraft photography. When shotting this kind of subjects you change the way you grab the camera, as you grab mainly the lens, long lens. For the other camera modes I use the traditional button for half-press/full-press and take picture.
Nice video, as usual 😉
Thanks, it is true, the method you choose is up to you!
Carlos DL but if you use BBF, you can simply treat it like single mode just by releasing the button! It’s the best of both worlds!
Also I find both your and Mattie's points absolutely valid.
I have shutter button focus for all my standard modes and back button for my custom ones. That way I can quickly choose which one I need depending on the situation.
Don't use BBF that often though.
I hear you Robin, in the 15 years that i have involved in digital photography and shooting many different subjects i have never used back button focusing for many of the same reasons you have spoke about.
Robin thank you for the video, I agree with your observations to a very large extent. I have over the years alternated from BBF to shutter focus and I have decided shutter focus and exposure is more practicable. At the point around 6min 20 sec you mention a delay between focus and pressing the shutter, I shoot mainly wildlife including macro and for 90% for the time I use Continuous AF, the reason being even when you are still or the subject is still one is almost inevitably not! So if you if you did use BBF and then pressed the shutter you would be in focus, I always pressed BBF before the shutter and kept it pressed as I pressed the shutter, the two actions can be simultaneous, therefore the likelihood of a correctly focused image is highest.
Never seen any use for the BBF, and the reasons are the same as yours. Started my photographing with system cameras in the beginning of 1970’s.
And when the working autofocus came to dslrs I learned the SBF , used it since then.
Glad you use the shutter button too and I am not alone in this.
I AGREEEEEEE! The ergonomics of "squeezing" is considered while designing a camera. I find that the back button is not perfectly placed for squeezing against the camera. This issue actually introduces camera shake in those moments that the shot happens quickly and I can't wait to take the picture. It places the "center of pivot" at the wrong position to ensure stability.
Good video, Robin, you made your point. Personally, I do love to use back button focus in all photo scenarios, like you said, it has become a second nature. However, I recently bought the Olympus OMD10 mark 2, and the button for back button focus is placed in such an inconvenient position! It's unbelievable!
that camera is not designed to work with BBF i guess.
I find the button placement convenient and comfortable on the em10 mark ii. It's a personal thing I guess.
The same for me. I'm very happy with BBF with my Canon, but with my Omd 10 mk II I don't feel confortable
I like setting a button for manual focus if I have to wait for a shot. The auto focus can get me there quick and the manual keep it there. Last night I was taking photos of children at a local carnival riding a small roller coaster. I set focus just after a peak in the ride so I could catch their hair in the air and the excitement in their faces. I didn't want auto focus to think I wanted another area in focus.
Since the days of " no auto focus" shooting film, we usually allowed for depth of field to help out and shot manual focus anyway. With this "built-in" history of muscle memory, it's pretty easy to move the focus clutch ring and shoot the same way - focus peaking is my best friend in this case........ You are correct though, it's always up to the individual to get accustomed to any shooting method.....
Yeah, we choose what works for us best!
My first camera was Canon 5D Mark I, bought one used about one and a half year ago. Recently by recomendation from Tony & Chelsy I bought E-M10 Mark II as my travel and walk around camera. On 5D I used BBF all the time, when setting up my E-M10 i quickly qave up on BBF because of ergonomics, those cameras are definitely not designed for BBF. Having said that I love my tiny E-M10 and it's pancake kit lens.
Thanks Robin for explaining where back button focusing does not work. It is extremely important for people like me who are trying to improve taking photographing, to hear and know where to use and where not to use different focussing systems. Thanks for the Vedio
No worries, I do my best to share as much as I can!
I use BBF for sports action and rarely otherwise. When shooting sports, there is usually a long lens on the camera and my left hand is supporting the weight of the camera and lens, so the right hand is only resting on the camera and using thumb for BFF and index for shutter is no strain at all. With a bigger camera/lens, I shoot with a monopod and the weight isn't really supported by either hand, so the same conditions apply for my right hand. Having said that, I have often used the shutter focus/release option in sports/action because of the much faster focus acquisition of recent cameras. When I got my first EM-5, I tested that fast focus quality in sports situations and was pretty amazed at how well it worked. As you say, it depends on how a person works and what they are shooting. I have not found it particularly useful in studio work, even though I sometimes use it there.
Yeah, it is important to test it out and see if it suits your shooting style. For me BBF just does not work.
it is all preference in style of shooting, i do all being said without any issues, no hand cramp for hours, no out of focus on low F number, no shake/blur. Focus & recompose to shot many quickly with sharp photos. Fast moving object towards or away from you, back focus with AFC, takes sharp photos very quickly without need of burst mode. Some camera has half press shutter; that even faster response, all coupled into one better way of shooting fast , accurate & sharp - one back focus, AFC and half press shutter.
I use BBF as I mainly do wildlife photography. Coupled with C-AF focus moves with any camera or subject movement and it works just fine for me. I can press and release to lock focus and then press again as soon as there is any subject movement (like the example you give of waiting for a bird to take flight). And for macro I just keep the button pressed until I've released the shutter. Also the ergonomics of the EM1X puts the AFL button directly under my thumb and right next to the rear dial so there's hardly any movement of the thumb needed either to focus or to change settings. The main advantage for me of separating the shutter release from the AF is that I find BBF more precise than the half press of the shutter button (ie fewer accidental shots!) when reacting to sudden or fast subject movements. As you say it's an individual choice and whatever works best for you.
Sure, if the BBF works well for you, keep using it
Good meaning friends have been convincing me to use back button focus. I personally feel that this method is not for me. I’m glad to know your reasons for not going back button focus. These reasons you mentioned align well with my thoughts about this subject. Thanks for sharing them.
Thanks for voicing up and yes, sometimes it is not for some people! So we decide what works best for us.
Everyone has their own way of working, and that's okay. Some of the issues you mention seem to be related to using single-focus rather than continuous-focus. Also, it's possible to press the shutter button while also holding down the focus button, eliminating any delay between the 2. And the only other thing that could be changed is that using a battery grip may make the camera easier to hold. When I learned about Back Button Focus, I was using a Nikon D800, and that camera didn't identify subjects as well as the newer mirrorless cameras. I still use it, because there are times when I don't need to relock focus over and over again, such as when taking multiple exposures of a group of people, and it helps to reduce battery drain.
Robin, thank you for your point of view. A while back I started using back button focus on my EM1.2 and after a while I liked it. However I also use a EM5.2 and BBF does not work for that camera, so I end up going back and forth depending on the camera I am using. After your explanation of the way you use yours I may go back to just using the shutter button for both functions on both cameras. It will likely be easier and less confusing.
i like BBF, then again i use a camera where the ergonomics are set up for this and it makes a huge difference and i also leave it in C-AF, horse courses just use what works for you
Good that it works for you!
And the Olympus doesn't!
i will agree with you on this. There may be a few cases where BBF would be a benefit, but not for my shooting styles. I do landscapes, architecture, and this last year really got into street photography -- all of which work best for me using the shutter button for focus.
I like this! Although I have used bbf for many years, this made me think it over again. In some situations I'm in trouble with bbf. It is always good to question things you do for time to time.
Yeah, there is no right and wrong. I am not denying BBF is good, just that it is not suitable for me.
I'm so glad you categorized the various types of shooting styles and photography in making up your mind about BBF. Thank you for this excellent video!
I thought you were joking when you commented on the other channel.
I do a lot of action street photography and just find back button focusing annoying for me personally and agree with everything you said.
I seldom joke, because I do want people to take me seriously. Glad that we are on the same page about BBF.
Some time ago when I came across the BBF video I believe it was Tony N. and I was surprised of how all this time I was taking great images without any problems, while Tony was explaining that I was doing it all wrong.
You can do continuous AF I believe and have focus on subject until you press the shutter. I find that my normal AF works perfectly well.
I agree with you, using the shutter button to do all can yield amazing results as well.
@@TL-xw6fh their arrogance like "I'm a pro, so I know better than any of you" and complete lack of humor keeps me away from N. family.
I really like back button focus. I also have the fn1 button, inside the grip, next to my finger for exposure lock. Works like a charm for me.
Good that it works for you.
Robin Wong there isn’t a way to set AEL when using back button focus on Olympus cameras, is there? I keep trying and it always triggers focusing instead...
There are times for it and times not for it, night is another one because you don't need to turn your AF off for focus up and shoot tripod shots, it's all a very personal thing and there are times it isn't so good, I just have a custom setting for BBF so I can easily switch it on and off without menu diving.
Yeap, that was what I tried to say, it is a preference, and we may choose what works best!
I like Matti & have watched a number of his videos having been introduced to him by PF (another superb Olympus Visionary) & as you say Robin, others like J Ellis are very knowledgable & accomplished photographers & yet Joseph in his opening statements states that he’s a people photographer, not wildlife & sports but advocates BBF. So unless I’m misunderstanding completely, he’s using it for exactly the reasons that you don’t ! Brilliant !
All i can say is how great full i am that you put this video together because for me, I’ve watched these guys & thought oh my gosh, this is another technique that i must learn to use if I’m to be a decent photographer! Well for now as least i can put it aside & don’t need to think about having to learn BBF.
Don’t get me wrong, i love these guys & will continue to subscribe & i get why it works for them, but really helpful to see that you don’t use it & more importantly to explain why & in a respectful manner without having turned this into a BBF bashing video. You’re words were carefully chosen! Thanks Robin, see you next time!
I do landscape photography a lot and for me bbf works perfect,especially when i’m using nd filters for long exposure shots. For me disable autofocus on the lens everytime before putting on my nd filters on the lens was a pain in the butt,using bbf in that situation is much more easy’er and faster to use. Good video though, i agree that for macro and portraits bbf is not the way to go 🤔😉.
I use Canon and it does have its place, how ever, most people think they have to half press, get focus and then take the shot. In reality a straight press will focus and shoot in one press most of the time. Or BBF put it in servo mode to auto track. It depends on what your shooting. There is no right or no wrong. Just an opinion?
Like I emphasized in the video, use what works for you. If BBF is suitable for you, use it.
Late to the video, all really good valid points, but I wanted to add that most of the points that were said apply mostly to small cameras, I have used Canon, Fuji, Panasonic and Olympus, and most of the stuff you mention are present in the smaller cameras (Panasonic and Olympus mostly) but in the bigger ones (in my case Canon) the BBF is in the camera thumb rest, so it does not feels awkward or uncomfortable (at least to me), most of the time I shoot with Continous AF so the BBF is mostly necessary (In my experience)
I was using BBF buf stopped recently. One point about the thumb rest discussion and disturbing your grip of the camera - I had my BBF set up to use the front button usually set to be the preview function. One of my fingers naturally rests near this button anyway when gripping the EM5mk2. But I stopped using it because I found that for shots of stationary birds I prefer manual focus anyway and the BBF setting confuses me when I switch to other modes or when I get someone else to use my camera to photograph me I have to explain it to them.
Exactly, I think it is not natural to hold the camera with just 3 fingers.
With the Mark 111 - to use back button focus and keep balance you have to use a front button - the best one is the Preview Button- Please try it - It really works it might improve your performance.
Did you read all my other issues? While the handling is only one problem, reassigning the AF button to another location does not solve all other issues.
Interesting points really valid points both ways are very good. Just a preference
There are a lot of soft people around complaining about how hard it is carrying a camera all day. It hurts my hands, neck etc
I suppose we’re not all made the same
Thanks for your video
Thanks, and yes it is a preference!
I do a lot of wildlife photography but I still don't like back button focusing. Instead I'll use the back button to lock focus if I don't want the AF engaging. Normally I want it to refocus between shots because I'm trying to focus on an animal's eye and small subject movements or focusing errors can ruin the fixed focus shot.
Thanks for sharing, interesting to find a wildlife photographer not using BBF!
Have tried BBF many times but like you it doesn’t suit the way I shoot.
Even when I do bird photography I find no advantage.
All good points. Thanks for posting.
Likewise. Thanks for sharing your experience.
BBF worked very good with DSLRs because of the different AF technology, however with mirrorless keeping AF-C all the time does not work with many lenses because the camera always hunts for focus so you never know whether you acquired the focus or not.
C-AF on Olympus newer cameras with Phase Detect have been wonderful to work with. I still see no need for BBF, the sbutter button is good enough
After watching this I've made a change on my G9. Your wright about the macro shooting being enhanced by only using one - the index finger for both focus & shutter release which reduces camera movement. Now, in my ' personal menu ' I've added ' Shutter AF ' so that I can quickly turn it on when shooting close-up / macro photos. Otherwise I prefer BBF. Thanks.
Thanks Robin for a well thought out and helpful video! I really appreciate your approach to photography and to sharing your insights and perspectives. You are very respectful of other options and the choices that other photographers make. I am grateful for that! I have never used BBF and I don't see a need to for the kind of photography that I do...mainly street. I also enjoy Matti Sulanto's channel and have also learned a lot from him. Please keep up the good work!
Matti is an amazing friend, and super talented photographer. I think it is crucial to be always respectful in what we do! Thanks for the kind words.
My preference is BBF but recently I have found a wildlife scenario that has me using shutter-button focussing. I've been trying Pro Capture Low hand held for getting shots of birds landing and leaving. I was having little success until I switched to SBF. I have now dedicated C3 on my EM1ii's mode dial to ProCapL with SBF.
Robin. Interesting topic which made me think about how I'm using my Oly cameras - I don't use BBF but how about FBF? From Matti's video I can understand that there are some times when you want a fixed focus, effectively leaving the focus in manual for a series of exposures. On the Panasonic bodies you have to move a selector but with the Oly bodies we can set up the Fn2 button for AF when the camera is in MF. Once the focus is set and the Fn2 button is released focus is locked and we can take as many exposures as we desire. This mode can be set as lever mode 2. Lever mode 1 can be your usual AF set-up. The only hassle with this is that in MF the AF framing indicator is not shown until you achieve AF lock. Y
Of course you may customize the camera to work the way you want it to. I keep things simple. One button to do it all.
Robin, I use BBF. For exposure I have to use center-weight metering. Is there a way to spot meter exposure when the exposure and focus area are not the same place?
I use half press and if I need refocus. Unless light is changing at a very fast pace I don't need back AEL button but if I need it it is there by default. I find no use for a separate focus button which forces me to use twice the muscles in my hands.
Yeah I like to keep things simple too.
I agree that BBF feels a bit cumbersome. But I thought that an important advantage would be the separation of focus and exposure when you focus and recompose, especially with the focus point in the central position: if you use the half-press shutter button technique for locking focus, you also lock exposure and then when you recompose, the exposure for the frame may be off. Or is it the case that with Olympus cameras you can actually have a continuous (not locked) exposure evaluation even after having half-pressed the shutter button?
Using focus and recompose is quite dangerous for the kind of photography that I do. I will move the focusing point to where the subject is and make sure the focus is critically accurate.
@@robinwong Thank you for your reply, that's interesting. For me, I found that on the street there is often little time to move around the focus point when you spot something interesting happening.
I have short thumbs so BBF has never been comfortable to use for me. I tried assigning focus to a front button for a while but that was just adding another step for no good reason so I'm back to half press and go. I could see the advantage of using BBF for shooting birds in amongst tree branches where you don't want the camera to shift focus from the bird to the branches everytime you shoot, so I might use the FBF for that. They each have their uses :)
Yeap there is no right and wrong, just choose the method that works.
Having used back button focus on my DSLR I adopted it for the EM1 mk ii I purchased. Not sure if it’s the size of the Olympus but I did find that as mentioned by Robin that for me it made the camera less stable and more prone to unnecessary movement. Especially for close up shots. So, I am going to revert back to using the shutter release button for focus to see how it works.
Finally somebody says it. Moreover, Olympus mysteriously doesn't allow to remove AF and AE from the shutter button at the same time -- exactly what you want for recomposing and shooting panoramas.
with sony a7 you can have it all. shutter button focus, back button with constant, d-pad with lock tracking and AEL button with direct manual focus.
I use BBF in CAF+tracking for wildlife etc, assigned to # 2 on my back switch, #1 is assigned to S-AF, simple and effective for me, have booth available since normal shutter function is in mode 1.
Good that it works for you. I don't shoot wildlife.
Good arguments!
I stopped trying BBF years ago, it does not work for me.
My thumb has better things to do, i.e. selecting focus points if needed.
All the best with using shutter bottom, selecting cont. AF/ single shot AF/ manual focus due to genre, in continuous AF sometimes focus stop button instead of BBF all the time.
My thoughts exactly! Just too many steps, I am a miminalist, I want as little steps as possible before getting the shot. Using another finger drains too much brainpower!
I agree Robin, I've tried back button focus and found it more confusing. I just couldn't get used to it, it is way more intuitive to half press I couldn't find any advantage to back button focus. It was like trying to pat my head and rub my belly at the same time! :)
Oh my, what a way to describe BBF, but yes, thanks for agreeing and I am glad I am not alone
That was really fast😅
I did not go out at all. That was the trick.
You guys are great. I always learn so much from both of you!
Thanks everyone, appreciate the kind words.
I tried it for a while, but it was difficult to get waist level (or lower angle) shots comfortably with back button focus. I sometimes take dog portraits where I have to get low to the ground. Shutter focus allows me to simply use my thumb on the shutter button to focus and shoot when I'm shooting from a very low angle, which is far easier on my wrist.
That is another valid reason that I missed out in the video. Thanks for adding in.
I use BBAF and photo birds in flight and pickleball often and it works for me. However you have made many valid points. I'll consider them in my other shooting.
made exactly same experience… used back button focus for a while and switched back to normal use for close to all scenarios! (own a E1 MII)
My canon 6D is incredibly comfortable when held with back button focus, it's designed well that way at least.
Use it if it works for you.
As is Nikon! It's the Olympus that is wrong! Watch them change it?
I shoot birds and wildlife with my old Zuiko ED 300mm 2.8 + EC 20 2x teleconverter. I have never been able to get used to BBF with that gear as I've always felt lifting my thumb makes everything very unstable. Even with the EM-1 Mk2, I'm not very confident. Maybe with a tripod, it would be fine but hand held; it is definitely a No, No! Thanks Robin!
You are right, handling is a big issue for me, glad I am not alone.
Rajesh, I shoot mainly sports and wildlife. For that I use a combination of BBAF (back button AF) and FBAF (Front button AF) and with the Nikon D850 or D500 it works very well for those venues. I program the back button for what I am planning to shoot most that day (i.e. if animal portraits single point AF, if BIF (Birds in Flight) then group AF. The front button is a different focus mode (i.e. if BBAF is single point, the front button would be group for BIF). That way, should unpredictable things happen as did today (with a Cara Cara plucking a seagull off the ground into mid air) I can quickly hit group AF and catch a wing or part of the bird for capture). All that said, it took practice, but is now very useful. I agree with Robin's point that this style doesn't fit all people, all cameras, all shooting styles, or all situations. Stating why you like something or don't is always helpful. Even though I shoot Nikon I follow Robin's channel and Joe's channel for Olympus. They have some pretty cool people using Olympus gear who do a nice job telling it like it is. Kudos.
I never find the back button is useful for focus, I set my back button to switch on MF. I have the amazing pro capture this and back button have no sens.
That makes sense, switching to MF is a good alternative
Yes, I switch to MF too. Especially if I'm using a tripod and my subject is crossing a fixed point.
@@mucklark6943 yes if you focus on the perfect subject and you don't want change it or refocus. Useful
Good video with some valid points well explained and argued - but I'll stick with AF-C and back button focus when shooting handheld; it just suits me and my photography.
If it works for you, then use it!
I totally agree.The same situation with street photography.
Thanks! Glad you share similar views.
Late to the video, but one more point that was mentioned in a video by someone who also doesn't use BBF is that releasing the AF-ON button with your thumb before pressing the shutter button is very counterintuitive and, as you mentioned, it introduces unnecessary handling movement, and it introduces at least a little time gap between focus and release which can easily ruin macro shots.
I *believe* I understand why many people prefer BBF, but I've tried it and it's definitely not suited for me or my shooting style. (Neither is using AF-C btw, I'm always on AF-S.)
I use back button focus because I find the shutter button, on my EM 1 mk 11, too sensitive . This results in photos
being taken while I'm trying to focus. Each to their own.
Good that it works for you.
BBF AF-lock is good for video shooting in Lumix cameras. It works like manual focus. No focus hunting in BBF. I prefer this nethod for video. But in photo shooting i use both as per scenereo.
Great video Robin, I have been using BBF and do like it even though I don't at times, I'll now switch back to normal and see how that goes, nice to have that option
yes it is always good to have options
My method for using BBF is to use it with continuous AF (AF-C), not single AF (AF-S). As long as you have your thumb on the AF-ON button the camera is auto focusing, you do not have to let go of the AF-ON button to press the shutter. When a camera has fast accurate AF-C, some do not, and is ergonomically designed for BBF, you can leave the camera set to AF-C and still have the instant choice of AF-C or AF-S by releasing or not the AF-ON button. Whatever method photographers use, if it works for you it is fine.
I use C-AF but I dont use BBF. It works and I have high keeper rates. I just don't get the need to keep pressing another button. And I need to securely grip the camera, I cannot imagine using any camera with just 3 fingers.
Another reason I don't like BBF: if using the battery grip (HLD-9), the AEL/AFL button is not really accessible in portrait orientation without reassigning the AEL/AFL button to F1. And to get the "natural" function of F1, you have to reassign button function to another button. Not worth the confusion IMO. And I agree, the half press and shoot seems faster.
Interesting argument on macro. I shoot a lot of macro with Olympus E-M1 II and the PEN-F, former with back button focus) and I really appreciate BBF for macro. But I use a different technique. I use either MF or S-AF with BBF, with autofocus only being used to get in the range of a shot, and then, with focus locked, I’ll subtly refocus with my body, at the nearest point of what I want in focus of the subject I’m shooting, and then I’ll either rock forward in a controlled movement and shoot a burst, or in magnified view will focus with my body and shoot when I have the subject in the desired focus. With the burst I can frequently stack some shots of even a moving subject to get more DoF. Coupling AF with the shutter I found I frequently failed to nail focus exactly where I wanted it on the eye.
But, as you say, what matters in the end is what the photographer enjoys. And a video like this that encourages a photographer from a different perspective may be just the thing that helps them to find the solution they love. So thanks!
And nice macro shots.
man, burst, rock back and forth, manual focus, those are a lot of steps!
I just rely on S-AF, move my focusing point to the desired spot on the frame, half press shutter button and press down quickly after AF is acquired. works every time.
And I did a video on shooting macro too, if you are curious how I did it.
Robin Wong I’ve checked out your other video. I guess I should have specified that the manner of shooting I described is what I use when I’m working at very close focal ranges (e.g. the face of a wasp) where an autofocus box placed on the eye, for example, is unlikely to place the focal plane where needed, or when image stacking is desired. Or in more extreme examples such as shooting a snowflake (which can involve dozens of exposures in sequence). It is a method similar to what Don Komarechka uses.
The method I described, for me, wouldn’t work reliably if shooting, for example, a bumble bee flying flower to flower. In those cases I tend to prefer a focusing method similar to what you’re describing here and would agree with your assessment. And I’d also agree, there, that back button focusing isn’t doing me any favors. S-AF would be my preference and pairing that with a back button and nailing the exposure with the shutter button introduces more lag and margin of error than would be the case if I paired it with the shutter button, and I feel like I get a bit fewer keepers with C-AF on the back button (though it has been decent for quickly-moving subjects like bumble bees).
I came here after seeing your comment on Matti's video! Cool to see you actually did it!
You are completely right . Hi Robin
Thanks !
Apart from the reasons you mention, Robin, there is an other factor that for me makes BBF a non-option.
Like yourself I wear glasses (with rather thick lenses, as I'm far sighted).
But I also have a left eye preference. So, when I'd use the camera's EVF, with the BBFmethod I'd have to wriggle my thumb between the right glass of my specs and the Focus button: how inconvenient!
BTW I've also switched off touch screen: my nose will unintentionally activate focus (focus to the lower right corner of the image) while using the EVF. Moreover I mostly prefer to use the EVF, instead of the screen: to have a concentrated view of my subject, without distractions.
PeterK
I don't use back button for the simple reason it does not work effectively with manual lenses.
LOL!!!; PERFECT
