this is the only review channel i will ever need. for being 20 minutes tony talked as precisely and quickly as possible.
You're an increasingly smart guy, Tony. You take a technical and even scientific approach when you look at a camera, but still keep practicality in mind. I mean you were able to do a better review of this camera than most will probably do hands on. Thanks for the awesome videos!
wow, im 5 minutes into the video and i had to pause it just to thank you that there is finally someone explaining all the specs that are so hard to understand sometimes. instant subscribe. looking forward for more of videos like this
I just loved your explanation about pixel density. thank you.
Great overview and comparisons. Looking forward to seeing the hands on with this! Thanks for the great content!
What's different about your videos is I find your explanations for the just turned prosumer very well constructed and thoughtful for those who are not familiar with every term. Subscriber now and will use your links if I make the purchase, keep up good work!
There are many other videos on Sony a7s II preview, but your videos have got more views..!!!
You are a great teacher Tony.!!!
I never comment on youtube generally, but this was one of the most informative review I have seen and I kinda liked your style. Thank you :-)
You are great at your job. Always a pleasure watching your informative videos. Perfection = Chelsea and Tony Northrup.
Best camera/lens reviews on the web!! Thumbs up!!
Great Details .
Thank you.
Super video as always. Very informative. Outstanding channel.
Excellent video!
Of course they announced the A7SII, literally the day after my A7RII showed up. I think I made the right call as I like the idea of having a more "all around" camera where I can get great stills if need be as well as good 4k video. I picked up an Assassin just for the touchscreen and other features because having worked with the A7S/Shogun combo, I knew that was the right call.
Great info! Thank You!
I'm looking forward to the full review of this camera ;)
I can't for the LIFE of me understand what the people who dislike this video didn't like!!! How many previews went into such detail on the reasons the A7SII is such a strong video performer in low light? Whatever! This was a great preview Tony!
Any news on improving the rolling shutter issue that Philip Bloom 'mentioned' in his review of the A7s (1)?
BTW you guys rock! Love your work Tony & Chelsea.
The cadence Tony uses when he says 4k sounds like the spanish phrase "por que".
Thank you so much for this video :)
There is new function in the menu "Gamma Disp. Assist"
This function will give you color graded preview when using S-Log2 or S-Log3
Many thanks for the comprehensive review, both technically and practically (including ergonomics). Tony, are you anticipating the same overheating issue as the a7r II ?
Hey. Great review! What about battery life time on the Sony A7S II?
Ha! It seems obvious now, but didn't occur to me that I could use a speed booster in super 35 mode on the a7r2. I look forward to seeing you do a test with that.
I agree with you on the need for F2.8 zoom lenses. For a hobbyist like me in my late 40's that would be a definite buy. the 55mm and 35mm I absolutely love but I just can't justify an f4 28-70 and f4 70-200. I really think they are missing out on sales of cameras without the 2.8 zooms. The lack of them almost has me wanting to sell off my Sony and go with Nikon or Canon instead. I want native lenses! The only thing I adapt are my takumars for the fun of using them. May I also add, I truly enjoy the format you and Chelsea provide. It's "inviting" for back of a better term and not pro a specific manufacturer, your honest opinions are appreciated. Keep up the good work!
Great video. I think you have some great honest information here. I make a lot of videos on youtube too so I'm really interested in the best video quality I can get. It seems like you are more into video than stills too. I would love to see you run the A7Sii and/or A7Rii against a high end video camera like the Sony Fs5 or FS7,
Great informative video and honest review! I'm really waiting for sony to make a gh4 nx1 version of their full frame cameras. We want tilting touchscreen. The nex vg series video cam is actually a good format with tilting touchscreen and good onboard mic. Sony should make one using the a7s sensor.
Thank you for your effort. I find your review pretty informative, honest and neutral. This is exactly what consumers are looking for. Keep up the good work 👍🏻
Thanks for the intro to the camera and the review. The original A7S is now discounted to being just a couple of hundred pounds more than a GH4 in some UK retailers. Since I cannot easily distribute or edit 4K at the moment - would you recommend a cheaper, original A7S shooting HD for now and, perhaps, adding an external recorder when 4K really takes a hold in a year or two and I can make more use of it?
Awesome footage! We shot our last movie "my days as a woflman" on the sony A7s with shogun. pretty nice picture quality :)
Nice video Tony!
In one of the videos from announcement Sony representative said that it is supporting HDMI Plus. Not familiar with this connector and all I could find is "Digital Plus HDMI", this looks like full size HDMI with some audio improvements.
Wow that camera looks great! Wish I could work with it :D
It would be very interesting if you could get the Black Magic URSA Mini 4.6K version and compare it against A7S / A7S II. Very different beasts, with the URSA sporting global shutter and 10bit with great HD downscale option, and A7S sporting crazy low light and crazy low light.
about the micro HDMI, Sony did give us a little accessory to hold cables in place without the need of a cage with the A7RII, so there's a good chance they will give us the same accessory with the A7SII at least.
great review as always Tony - yes it is amazing how few lenses Sony is putting out - and no F2.8 zooms which is amazing - and seems like Sony has just totally forgot their APS-C E mount - which has had no new lenses for ages and no F2.8 zooms either and will never I suspect -
tony whatever happened to your in-depth post-peru definitive followup review of the a7rii????
But it can also do a review for Canon 1DX, although already old pear on youtube lacks a comprehensive review as you can do it yourself with all the details for me are the best that you can do this job perfectly explains things full attention thanks tony hope that takes into account my request for CANON 1DX
Thanks for the video Tony! I always enjoy your work... I've been waiting for the 7S II for a while now. I am still shooting with a GH3 on a rig and I must say the form factor is not ideal. At this point I am very much considering a dedicated camcorder such as the new Panasonic AG-DVX200, or the JVC GY-LS300. The JVC has the ability to use most lenses on the market with its 4/3 mount and Variable Scan Mapping technology. The Panasonic uses a 4/3 sensor and fixed lens but is an all in one grab and go set up. Considering the price for the camcorders VS price for the Sony and the additional gear needed to operate an SLR style camera (rig, xlr adapter etc etc) I am not sure for a one man band such myself it's worth it. Of coarse this all depends on what a person is looking for. I am just thinking out loud here. Maybe people don't realize the amount of additional gear and extra time involved in using a SLR to shoot good quality video.
Cheers,
Greg
This was an awesome video. One thing, the "APS-C mode" on the a7R II - isn't that just digital zoom? You could easily just crop the full frame in post couldn't you?
+SeanHodgins no, the middle of the sensor and lens is used so it gives the effect of zooming but its not zoom plus the best part of the lens is the middle
LockCircle is coming up with a micro-hdmi to hdmi lock adapter. Coming at the end of September.
I am loving the video capabilities of that camera! Makes me want it for that alone. 3k dollars, though...
Btw, you always manage to give your videos those nice touches that sets you apart from the rest. The production value (as I've mentioned in other comments), and fun little details like at 1:41 (line from record button to the word "Awful"). Stuff like that really makes a difference :-)
@Tony Northrup doesn't Sony include since A7Rll the clamp for the micro hdmi so it won't pull out?
And about the form factor, is an advantage if you use the camera in a gimball like the letus helix or movi.
Hi,Great information, I want to buy a7s2 for featur film making so that i want to know about lenses which lenses for suitable for this camera i mean to say whats kind of block lenses use for it.please guide me
finally subscribed.
Does the A7s ii still have the crop in 1080p or is that feature completely gone? :o
Hi Tony,
I've been considering to move from my canon to Sony A7S\R II for a while
?in case I will use my crop lenses, can I still get the sensor to work on super35 and to be able to shift to APS-C
also do you have any idea if the AF will still be useable for stills on both cameras?
thanks a lot !
wow, i feel like this is actually quite a big step up from the a7s, even while considering the $500 mark up. do we know if it can send 4k out micro HDMI while recording 1080p at 120 internally? or any other internal record while sending out 4k, for that matter?
can u tell me how to make 50p progressive video a slow mo in sony vegas ??
what would you recommend for low light (club scenes) 4k camera?
how do you turn the IBIS on/ off? it seems as if anyone can do it but i can't find it on the menu or see if it's actually working
Tony, with video, I will be able to trace fast moving objects against the fixed stars. I need your advice on where to get a bundle, camera and lens deal. Thanks
+Richard Mondio Oh, interesting project! Re: bundles, I haven't seen anything like that available. I'd just buy a used lens--you probably won't find a good deal on the a7S II while it's new. Enjoy!
Slog 2 native iso on a7s II is 800 too. You can do both Slog 2 and 3
Hello Tony, what do you think about the new pricing for the Alpha series? Is this justified?
Tony is one smart dude. Well done. Oh, and Chelsea is pretty awesome too! :-)
Tony, I wish I didn't come across your wonderfully put together A7s II review, because now I want to buy it! The stabilization, touch screen, 120 fps and S-Log3 all made me rethink getting the original a7s. My main purpose is to video shoot the stars/meteors/satellites at night. Along with this new A7S II, I want to get the F 1.4 35mm lens and use the android app for remote control. Do you know who would offer this combo for me, and what accessories do I need to buy in order to make my purchase a total package astronomical dream come true?
+Richard Mondio Sorry, I don't know enough about what you're doing... Astrophotography is very specialized, and I'm not sure why you'd be shooting video (as opposed to a time lapse). Have you checked out the D810A? You'll also want to research the coma of various lenses.
Hey are you sure the metabones speed boosters actually do give you super 35 coverage? Super 35 is wider than apsc
the competition is very strong awesome job Sony. now i can get a A7s II added to my collection with the D810 =D
great comprehensive video. i t possible to do 1080 120fps on the a7s 1st gen using the atmos assassin or something similar?
+Elliot Tebbs No it isn't.
The FS5 they released looked more interesting to me than the A7Sii for video. Being a photographer though, I couldn't lay that much down on video. I'd go for the A7Rii. But as much as I like that camera, I still need the ergonomics of the Canon, the lenses, being extremely fast with it. I had the original A7R and did landscape shots with it, they are doing well. I still would like to see a pro body. Even though it would be bigger, I don't think mirrorless has to be about being smaller. Adapting lenses isn't a big deal for landscapes and things like that but every day shooting I don't want to adapt the big Canon zoom to it. For video I would. I don't care about auto focus in video.
+nagol5178 Yeah, we have a DSLR crowd on this channel, but most filmmakers will be happier with a proper video camera like the FS5.
I will say that the a7S (and II) have one HUGE advantage--that full-frame sensor gives you background blur and low-light capabilities that you would need to spend $30k to match in a proper video camera. That's why so many people, like us, have hacked together a video rig from what is basically a body designed for stills.
Yeah, I've always shot video with full frame. I do have a smaller sensor I shoot 4k on right now. But I figure the super 35mm cameras will be a step in the right direction. Especially if you have 2.8 lenses. The problem is, if you put one of Sony's F/4 lenses on there, it's not gonna look like F/4 on the full frame. But that's still a shallow depth of field. Sometimes I forget how big an APS-C sensor is. Then I shoot something with my 4k video camera and remember, even F/4 on the super 35 is probably a good bit. I still would rather have a full frame sensor because I like that look.
Tony, you're awesome
Just bought the original lol, but I knew this would come and looking at that price tag I'm not disappointed
Will the A7s get cheaper now that the a7sii is coming out?
Your videos are always extremely informative and look well beyond most other reviews but this one went even further with the in depth analysis..thank you!
Oh..and your phone records 4K? Must be Android (or if you are using iphone you are lying..haha) Congrats
+Nigel Naughton Yeah, I have an S5, but we did just order Chelsea an iPhone 6S, which has 4k.
+Tony Northrup I find that the only reason I use the 4K recording on my S5 is when I'm on the road and I'm driving by an accident scene, I record in 4K on the way by and can grab clean frames for social media posting. Even though I own a 4K TV, I find that 1080p is still fine (it upscales really well) and the 60FPS is probably the better want to go at this point.
Although if you really want to demand something nutty, ask the manufacturers to make 8K @ 120FPS; native ISO 3200 q/ SLog3. That's not asking too much. It would only cost a few million dollars after R&D costs are factored in... And weigh 30lbs. LOL :)
+SeanFromPVD You do know UA-cam already has 8K video though not @120fps. And IMO 4k on a phone just sounds like bragging rights because it's not like you can record very long on those either before you run out of space with all the extra diskspace 4k eats up! 4k@30 just is fine since most people won't notice difference between 30 and 60 just like no one is missing 120fps.
daviangel I do know that they have '8k' showing, but with the manner of compression that is used to make it viable from a bandwidth perspective, it won't be as clear as raw 8K. Most likely it would have significant reductions in color space and the actual pixel count may be based on an algorithmic estimation, rather than actual point data. (i.e. This many pixels will be 'red' from this point to that point, or dithered to this degree over this space.)
This is why downscaled 4K to 1080p can still look better than 1080p; and upscaled 1080p to 4K looks worse than native 4K.
The difference of 30-60 FPS is noticeable, but mainly for the purpose of frame grabbing and cropping videos. About about 65-70Hz+ it starts to seem the same. While you can get 144Hz refresh monitors, using something like free-sync can smooth 72 FPS sufficiently to make it seem as good as 144Hz to the average person. (Because there's no tearing or jitter perceived.)
Everything you just said also applies to 4K so like I said it's not really viable nor ready for the masses. Maybe if they actually used High Efficiency Video Coding (HEVC) for the 4K video on the phones, which I doubt, because I haven't heard anything about it. I"m guessing they'll come up with custom proprietary stuff like Sony. I assume this camera uses XAVC to record 4K. pro.sony.com/bbsc/ssr/micro-xdcam/resource.latest.bbsccms-assets-micro-xdcam-latest-XAVC.shtml Apple should instead have native HEVC support in their next OS 10.11 and iOS 9 if they don't already IMO. Windows 10 has native HEVC and even the new Intel CPU's. GPU accelerated decode of HEVC video file format including both 8-bit and 10-bit support. This will provide improved video playback capabilities on the platforms listed in the following table. communities.intel.com/thread/59216
love your videos!!
But,I have a doubt,I'm a street photographer and I like to portray my perspectives only on Instagram,will the a7s's megapixels do,or will I have to change to some other body which has more pixels.and will it matter.
-a7ii or a7s
How do I choose.?
What's the battery life like on this compared to it's predecessor?
Hi Tony.... I will just wait next month...Maybe there will be Sony A7X..... specs would 4k/60p, HFR 960fps, IBIS, 1920/240fps, 54.4 MP.....LOL. Anyway thanks for your informative video.
Some good improvements here, but I hope that it does not overheat after 15-20 minutes ( like the A7R II ) and this becomes the Achilles heel of this camera. Will have to wait for the reviews to start coming in once the camera is available.
Hi
Sony just stated that they are going to release 8 more lenses by early 2016 and they are going to provide 14 bit uncompressed or lossless files option i guess.
Hi tony, thank you for the review. Could you try AF of the Sony alpha 7rIII with the Canon ef 400mm ?
+Sosa Sebastian We tested it with the 100-400 and 500... it doesn't really work above 200mm in a way that's usable in the real-world. ua-cam.com/video/C1kI4NacaUw/v-deo.html
Tony there are 2.8 lenses on the A mount system you could adapt them on the E mount system easily
+elr2141979 True, but the Canon lenses (and Tamron/Sigma lenses for the Canon mount) tend to be sharper and cheaper, and they're just as easily adaptable.
+Tony Northrup the Sony zeiss 135 1.8 is the sharpest lens on the planet.
+elr2141979 That is a great lens but no. The Zeiss Otus lenses are.
I really hope that the high frame rate 120fps is using a full sensor readout rather than on the original a7s where it would only do 120fps in APS-C Crop mode. Fingers crossed.
How would you compare A7sii and A7s to blackmagic pocket cinema camera obviously for video only as bpcc is video only.The blackmagic can also be paired with the ninja assassin and I think they give you some color grading software with it.
+Brendan Daly The BMPCC has true raw video, so it can theoretically be cleaner when it's graded... The BMPCC also has better usability. But the a7 series is full-frame, which gathers more than 4x more light, so it'll be cleaner in low light. Plus, you get to take full advantage of all the full-frame lenses and their background blur.
Tony, Is there a video cam you can suggest that will take high resolution videos of the night sky for the purpose I have already described? In other words, what would be my other alternative if I chose I video cam instead of the a7s II with a night super sensitive chip?
+Richard Mondio I think your best bet will probably be an a7S (with an Assassin) or a7S II. If you have the budget, the Canon ME-20F-SH will probaby beat it... but we haven't tested it yet.
adding an external monitor is crucial for critical focus, a proper suite of shot exposure tools (histogram, vectorscope, waveform, and rgb parade). For people who are doing serious video, at whom this camera is targeted, they realize that the body alone is frequently not enough to frame, expose, a capture the highest level of video. also external monitors allow you to use LUT when filming in slog. For that you need a monitor.
Even if you purchase the a7s II, you will still need an external monitor, unless you're exclusively a run and gun shooter.
I think the real strengths of the a7s II are: short internal 4k clips (we've yet to see if it's affected by heat issues the way the a7r ii is), expanded slow motion, IBIS, and improved focus. If these things are important to you, the a7s II will be a good buy, but you will STILL need an external monitor. If they are not, the a7s is still a superlative tool fully capable of incredible results.
+trevorpinnocky Yeah, I agree about the external monitor. We do a lot of run-and-gun (and a lot of not-run-and-gun) and so I don't always use a monitor, but I often get back to review the shots and realized I missed focus, or focus drifted...
How much of the higher ISO do you think is just higher noise reduction? It is supposed to be the same sensor?
+FilmFactry I think it might be the same sensor, but I haven't had that confirmed.
@Tony Northrup Does this camera do autofocus touch screen when equipped with a sony lens and a shogun/assassin?
+Marko Aragian no
Hey Tony! I love the videos and I have a question. What would you recommend? The sigma 17-70 2.8-4 or the sigma 18-50 2.8? and how do those lenses compare to the tamron verison?
+Bryan Coronel Go to Northrup (dot) photo. Click on the Gear tab. Go nuts. :-)
+Bryan Coronel
The 18-50 f/2.8 is replaced by the better Sigma 17-50 f/2.8 OS. The Tamron 17-50 f/2.8 non-VC is sharper, but it's autofocus motor is slow and noisy and it doesn't have stabilisation . The Tamron 17-50 f/2.8 VC does have stabilisation, but isn't as sharp as the older version or the Sigma 17-50 f/2.8 OS.
The 17-70 f/2.8-4 performs nice, but isn't f/2.8 through the range, so at 50mm it is a stop slower (and has more DoF) than the constant f/2.8 zooms.
He didn't mention that full sensor readout without binning and line skipping eliminates moire and aliasing.
Hi there, does anyone know if I can use the same metabones adapter and batteries from my Sony A7s on the Sony A7s II?
+Olga Santos Yes, it should work the same.
Why no mention about the reported (and significant) overheating issues with 4K recording in the a7r2 and, since the a7s2 shares almost ever significant design detail (body, ibis, processor, etc, but not sensor), why you think/don't think the a7s2 will share that problem.
Especially since Sony said they didn't do 4K internal in the a7s1 because of overheating problems. And because it appears as though they might be using the same sensor in the a7s2 as the a7s. Or do you think that the low megapixels of the a7s2 sensor will keep it cooler... even though at 4K the data is the same?
This overheating basically eliminates the entire Sony 4K capable a7 series from my consideration because I record events and can't use a camera that has to have a cool down period after 15 to 40 minutes of nonstop recording. Any feedback appreciated!
Hi grate video
What is the difrence betwen a Full Format sensor A7r ii or a Sensor from the sony a7s ii what us a better sensor thanks for the Answere
+TeamOnTheTop The a7R II skips pixels whereas the a7S II doesn't. This shows a comparison to the original a7S: ua-cam.com/video/C1kI4NacaUw/v-deo.html
+Tony Northrup but isnt it bad wen it skips Pixel ????
But what us better Full Format or Not?
Thanks for the Answere.
Now this A7S ll will be the ultimate 4k low light video camera!
whats up with the white balance?
Hey Tony, thank you for this very informative video. Are you 100% sure the a7s II won't have the Super-35 option ? Because the a7s has it. If so, I'll be really happy I got the a7r II ! Having this new option when filming with my 11-24 is such a great advantage.. it gives me a 16-35 (ish) when I need it.
+Francis Hehle I'm 100% sure it won't have a 4k Super-35 option because it doesn't have enough pixels. It would only have 3.5 megapixels with a 1.5X crop, and it needs 8 megapixels for 4k video.
And yeah, I like the Super-35 option, too.
+Tony Northrup Makes total sense. The only thing : The old A7s also has that 12.2MP sensor, but still does Super-35. That's the part I don't understand.
+Francis Hehle It doesn't do Super-35 for 4k video.
+Tony Northrup Oh, I didn't know that ! Then I'm really happy I got the a7r II. When I saw the a7s II announced right after we bought two a7rII, I was a little upset (because we only do video). But for us the Super-35 option is a better advantage than the low light performance of the a7s II. Thank you for the info :)
is the A7s II the same body as the A7R II? would it fit into an a7R II Rig?
+Skyler Sorenson Yes, same body, should be fine with any a7RII/A7II styled rig/cage.
Yeah, that Ninja Assassin looks great. I think I'll keep my A7s, get the Assassin and just try to be a better film maker.
Good videoo
Solutions: Still photography: D810, 5DSr, A7R II with optional tripod. Only hand held - D750, 5D MkIII
Video/Film acquisition: Arri Amira, Sony FS7, Sony F5, Blackmagic, Canon C300, A7s/II w/ recorder
Slow motion: VR Phantom series, Sony FS700, Sony F55 (up to 260fps)
This is for real work btw :)
Only hand held: add the a7r ii. The 5 axis stabilisation is amazing for video!
Pros would use a gimbal of some sort but as a last resort sure.
I'm not certain this is true but from my experience with the color profiles that flatten the image they give a much much better dynamic range (using Alvaroyus on my D610 brings me from about 13 to 14.5 stops), but doesn't it show a lot more noise in any low light. I did a little bit of testing myself even at 400 ISO I was getting much more noise than using the normal flat profile (but there was as previously stated, much more dynamic range). Is S-Log 3 that way? It does an awesome job for what it's for, but wouldn't it cause a lot of noise?
Log curves are flat around normal exposure (lots of color data there) and then even more flat around the extremes. So if you in post decide to keep a lot of the extremes, they probably will have some issues. How noisy your image will be depends a lot on if you exposed correctly and what choices you do in post, so there is no yes/no answer. Crushing the blacks is a common way to kill noise in shadow areas. For the record I haven't been grading neither Nikon nor Sony footage, so just speaking for my own experience with BMPCC & Canon.
+ArrKayCee Yeah, recovered shadows are noisy on the a7S with S-Log. We only use it when we need the extra dynamic range, and then we have to very carefully adjust the exposure to maximize what we squeeze from the histogram--it'll usually underexpose by default.
Greetings Tony Sir,
Nice video and good information, I was looking to upgrade camera for wedding and fashion photography was thinking for nikon D810, here in India we have long hour wedding functions and in summer weather extremely hot how is the battery life of A7RII which one would you suggest Nikon D810 or new Sony A7RII ?
+Simranpalsingh Kohli I definitely would prefer to shoot a wedding with a D810 or (better yet) a 5DS-R instead of the a7R II... mostly because of lens selection. There are no native f/2.8 zooms for Sony's E-mount system, and you need those for weddings. Or, at least, I need them for how I shoot weddings.
Thanks very very much Tony Sir for the help and suggestion :) really appreciate it you are the best of the best in giving point to point advice and suggestion you are my idol :)
You can't autofocus with a Metabones adapter and Canon lenses?
You can but it sucks so much you are better off manually focusing
Thank you for mentioning the 30 min time limit. No other sites ever bother to mention this deal breaker artificial time limit. Sony is still protecting their higher end video cameras. An no, I don't want to hear about the EU tax excuse. I live in the U.S. I guess it is the GH4 for me. I have a GH2 and love having no time limit other than battery life.
Thanks for the video!
+jeffhalebopp sony is not the first or only company to do this.
+Wayne Summers re: 30 min time limit. Yes for sure. I guess it is far easier just to say the one and only company that doesn't cripple their whole consumer product line which is Panasonic. Every other brand you are guaranteed a camera with a crippled time limit. I am referring to mirrorless consumer cameras of course, not ridiculously expensive pro cameras. It is nice that at least Panasonic give us people without a lot of money a choice.
To make it short: A7RII usable up to ISO 12800 and brings 42MP (Makes a good FF-Photocamera). A7SII usable up to ISO 25600 same as A7S (I). A7SII better 120FPS (1080P) Feature set. A7SII makes the better video camera.
nice
Tony when shooting low light with the a7r ii in video it's better in apsc mode/super35 when over ISO 6400, is it the same for shooting stills, do you still gain that benefit. Thanks
+David Huxley No, you are using all pixels for stills (no binning like video)
Dalibor Mrkic thanks dood, I thought it didn't bin any pixels in apsc video mode on the a7r I but did in ff
+David Huxley APS-C in crop mode is 18.6 MP still to much for 1:1 4K
4K with 60fps would definitely generate heating problems in such a small device with such a huge sensor. Thats the reason why it was not implemented I am pretty sure. Tech moves on and at some day it will be possible, but not today. It is already a big achievement to do 4K internally with huge sensor in small device and 120fps now with FullHD.
There are great benefit to the fact that the controls are the same across the entire line. That is one of the things that I hate about Canon that every camera has a different layout and one thing I love about Nikon that no matter which camera I hold in my hands the controls are familiar. I fully use the A7II and A6000 and the wheel is just fine.
As far as the A7SII, I am disappointed. One of the main reason I switched from Nikon to Sony was the low light performance from the A7s and the huge savings from not having to get the D4s. But I am a photographer and not a videographer so when I saw that the new A7SII only had contrast point AF and not Phase detection . That is a bummer and made the A7SII useless for me. The irony is that what I have already spent on the Sony system I could have bought the D4s. :(
That said. I am happy with the A7II and the A7RII spite of it weaknesses over DSLRs. Just wish the A7SII would have been a photography camera.
Having less pixels vs more pixels in the noise battle actually does make a difference, but it works in slightly different ways. More pixels means every pixel is of worse quality, but since there are more pixels, they kind of even out. However, if there are too many pixels, at too high of an ISO, not even the sheer number of pixels will discount for the fact that each pixel is shit. Thus, having fewer pixels can mean having a higher quality when looking at the picture as a whole in the more extreme situations.
+Baba Wethu I found no relationship between pixel density and noise: ua-cam.com/video/_KYvp8PrCFc/v-deo.html
Tony Northrup I have watched that video and I agree. It's just that I realise that in more extreme cases there can't not be a difference. Let's say we have a camera with 4 times as big pixels as another camera. At one point, the ISO will be so high that the pixels only show complete darkness/whiteness/redness or whatever. However, when every single pixel of the higher density sensor shows complete darkness/whiteness-etc. the other sensor with 4 times as much might still be able to retain some information for each pixel. Making the higher resolution pixture 100% blown out whereas there is still some detail in the lower resolution's image.
Of course this isn't a real life scenario, but it still proves that there obviously can be a difference.
Erik Jans Let's say the minimum amount of light a pixel can capture is 1 lumen. Let's say that the lens outputs 2 lumen per 4 pixels. This means each pixel picks up 0.5 lumen and all pixels show complete darkness. However, another camera, with 1/4 the amount of pixels; i.e. each pixel is 4x as big, will recieve 2 lumen for each pixel, meaning every pixel will be able to recieve information.
+Baba Wethu Ok I get your point but i never thought about it like that. I don't think there is a specific threshold under which there is too little light for the pixel to detect anything (within realistic lighting conditions) but rather that the innate noise of the pixel/electronics will affect the signal more if the light is lower. And by combining 4 high noise pixels you get a single pixel with better signal to noise ratio. I'm not an expert though so I might be wrong.

This is a great video. Although hope the A7SII gets a firmware update (wishful thinking) to be able to use S-Log 3 at a stop more at least.
But what kind of lenses personally do you want on the Sony A7 system? Focal lengths I mean also. I'm asking since I feel most of the zooms and primes fill quite well for me so far including the manual focus ones.
+Neopulse00 "Although hope the A7SII gets a firmware update (wishful thinking) to be able to use S-Log 3 at a stop more at least. " stop more would be 3200 ISO, and you can use it 3200, 6400, 12800... you can't go lower
+Dalibor Mrkic I meant 800 obviously not 3200.
Neopulse00 That would be nice.
+Dalibor Mrkic Yeah that would be. It's possible I have come to realize with other companies that were able to give quite crazy firmware updates like adding 4k recording when there was not before or better mechanical functions like AF thanks to updates. So it is possible. They might be holding back because of their video camera dedicated line like the FS700. But it is possible in my opinion.
Neopulse00 Never heard of somebody adding 4K in firmware. Yes AF algorithm can be improved with software, not mechanical part.
