Hello ! Please help me, I have a 50 1.4 and a fungus under the front lens, can I remove it without disassembling the lens? There are 2 holes on the front of the plastic plug, if I unscrew it, can I take out only the front lens? Thank you !
I wouldn't recommend it: the force you have to use might damage the lens inside. It is safer to disassemble the lens like in this video, and then clean the front lens.
Thanks to you, I fixed my wife's camera! Thank you for the video, it gave me the confidence to take the lens apart. Was not as mysterious and risky as I had previously imagined.
Thank you for this excellent video series, my 50mm works again. Very well explained and demonstrated, to the point and not rushed. Much appreciated, please continue with more Canon lenses and bodies.
Thank you! Fixed my 50 by following this. It had a stuck focus. I mean really jammed at the far end. It had small but pretty "sharp" bends at the end of the metal sleeve grooves which I carefully hammered straight against a countertop. That did the trick at least for now.
nice. thanks. just bought a used lens to save some money. glass and lens is clean but focus ring sounds like there is sand inside. was just wondering how to clean it before i decided to return for a new lens.
You're welcome, I'm glad that you like my video. I would recomment to partially disassemble the lens, and then you can clean it under the manual focus ring.
Hey, Thank you for this video. I had a slight dent which I fixed. Put it all back together using your other video and now it seems to not be able to focus, it’s just keeps searching… But In manual it will show the focus locking. Maybe I put the brush on backwards or something I’m not sure what I could have done wrong.
Great video. Very informative and focused on the problem. I managed to repair my lens. I don't thing the metal ring was too deformed (only a little bit), however I slightly ground the main part which caused stiffness of the motion. Now it works without any problem. Thank you so much.
Hey brother this video was fantastic. Thanks to you I have a better understanding of the lens structure and workings. I was able to get an annoying little hair that was lodged in there.
Dude you are a fucking saint. I've had this lens for years and it ended up in a bag away for awhile. I got a new camera it works on and tried to crack it out and had this issue. Your video saved me!!! Was easy to understand and worked like a charm. I didnt put the connectors all the way back at first so I had to dissemble twice but the second time I was so confident it only took me minutes. Thanks so much!!!!!!!
Thank you for this series of video, very interesting. I have discovered some fungus starting to grow, after this lense being packed away in a box that got damp during a recent move. Could you talk about what you would use to clean the fungus from the lens elements?
Hi thank you for your informative lens repair. Would you at some time take apart a Canon EF 50mm f3.5 compact macro lens, mine has a problem with the infinity mark not aligned, as if it had been pushed over to far. It is a slight problem only needed to be correct when doing depth of field checks. Thanks in advance 👍
@@CamerasLensesEtc yes just past the mark. Just a small annoyance. When I switch the camera on and the lens is at infinity with auto focus it is jammed. So to free the focus I switch it to manual focus and move focus and that frees the jammed focus ring. Those that help?
Good video, my focus now working manually but new fault is aperture gets stuck. This causes camera communication error. Tried strip down again and set aperture to f1.4 as soon as rebuilt and attached to camera it stuck on next picture
Check the cable with a multimeter, maybe it was damaged, also clean the end of the cable other idea: check if you can close and open the aperture manually, and it is running smoothly. If that doesn't solve the problem, then you have to replace the aperture, or open up to f/1.4, and disconnect the cable, and use the lens at f/1.4 only.
Hi! Yes, you can, but even though you can remove the ring without disassembling the lens, I would recommend to disassemble it, and hold that lens element to avoid the inner metal ring to be damaged.
I was using a very special, professional tool used by only professionals. :) OK, just kidding... is it a jar opener tool: www.ebay.com/itm/254368045126
Grest video but there is something still missing and any other video on UA-cam shows how to disassembly the front element lenses to clean the dust and fungis between them
@@RONIGLAHNYou might try to unscrew the front lens element using a lens removal tool. (I haven't tried it, but as I see, there is two small cutouts on the front lens unit, so seems that you could unscrew it). I would recommend to disassemble the lens for that, and hold the front lens element. If you would do that with the lens assembled, it could damage the it.
hi, do you think it's possible to move the rear lens already on 4:10? I just need to clean the fungus on the lens part where you used a jar opener and i'm afraid to butcher the lens if i remove all the cables XD hehe
You can try to remove the bayonet mount, then you have access to the ring which needs to be undone. If the ring is stuck, then I would recommend to disassemble the lens try that way, because you can damage the sliders if you use too much force.
@@CamerasLensesEtc it turns out that the fungus is inside the lens at 13:36 part. huhu i'm sad :( i have already disassembled everything and i still can't clean the glass inside :( any tips? huhu
There are three lens elements on the rear of the lens: one in the ring which you remove (the last one), then there is one which is loose inside (it falls out), then there is one under that. As I remember, none of them is two lens elements glued together, so you can clean the surface of them. The important thing is to remember which way the middle lens element was in the hole, and you should put it back the same way.
@@CamerasLensesEtc I have just finisheddddd doing everything and it still works great!!!! huhu Thank you very much for your quiet, clear and very helpful disassembly and assembly tutorialll!!!!
@@CamerasLensesEtc I was able to get it out!!! by the way, I am very amazed at how clean your lenses turned to be even at the assembly! I just can't control the dust around me and had a hard time making the lenses dust free huhu XD but thank youuuuuuu. no more fungus... but dusts :)))) a little dust :((( hahaha
Did this and now I have full range of manual focus again, but autofocus doesnt work. It goes back and forth around the proper focal point a couple of times and gives up with the red focus square. Any ideas?
I didn't find a video for the 50mm *1.8* Some dust, maybe sand, is inside the focusing ring ... This 50mm 1.8 has not that screw neat the ring, at the front like this 1.4 Could you give me some recommendation about how to remove the focusing ring of it, please? Thanks!
Hello! Currently I don't have video for Canon 50/1.8 II lens. Here is a brief explanation how to disassemble it: first remove the two screws from the rear electronic connector, then remove the panel of the AF/MF switch which is glued to the lens with two sided adhesive tape. Under that there is a screw which holds a metal pin, remove those. After that the inner part of the lens slides out. The lens consists of two parts which holds the manual focusing ring. On the opposite sides of the lens there are one-one small plastic wedges, which you have to lift up, then remove, then the lens can be separated into two pieces, and you have access to the manual focusing ring.
I've been searching a lot but can't find a solution to my problem. Maybe you're so kind to help me with some info. I bought a second hand canon 50mm 1.4 about two years ago, and since then i had a lot of problems with the focusing system. In one hand, the focusing ring is not smooth at all (i know this happens to many users), but in the other hand, the autofocus misses the focus point too many times. It doesn't seem to be a front or back focus problem. It just misses the focus. Many times in low light, of course, but also in well lit situations. I like to use this lens at f1.8, so it is very noticeable when it happens. I thought about buying a different 50mm lens, but good ones are very big, heavy and expensive compared to the canon 1.4 lens, and many reviews claim that the autofocus in this canon lens may be even more accurate than the sigma art 50mm 1.4 autofocus, for example. So, do you think it is just that my lens is old? Do you think it is something that can be repaired by a professional to be ok again? Do you think the cost of this repair is worth it? Thank you in advance for your advice, and thank you for sharing all that knowledge in your videos
Hello! If the focus is not smooth, then I would advise you to disassemble the lens, and check what is causing the problem. I have this lens in my personal photobag, and I experienced this focusing problem: sometimes the lens (camera) can't find the focus, and this happens mostly in tricky lighting situation (backlit, shooting towards the sun...). When the focusing happens, the lens is in f/1.4, and if you use for example f/1.8, then the lens will be stopped to this aperture right before the picture is taken. I haven't used the Sigma 50/1.4 ART lens, but the reviews are very positive about it. So, here are my solutions: 1) disassemble the lens, check what is causing the not-smooth focusing, and try to repair that. Maybe this is the cause of the focusing problems. (you can do the repair for free) 2) Borrow / buy an another 50/1.4 lens, and compare it to yours. If an another Canon 50/1.4 performs better, then you wil know that something is wrong with your lens. Other option (in the same price category) would be the Sigma 50/1.4 lens (not the ART version). If you use APS-C camera, then the Sigma 30/1.4 would be an another option, or if the f/1.4 aperture is not that important, then the 50/1.8 STM lens, or the 85/1.8 USM lens would work for you.
@@CamerasLensesEtc Thank you very much! Maybe i'll do it, but I'm a little bit hesitant to do the repair myself, i fear that i may do more damage than good to the lens, and even when it clearly has a problem, it stills serves me a lot. I'll try to find another unit of this lens to compare it to mine, and also try other 50mm lenses. The 50mm 1.8 stm from canon i already had it (twice, the first was stolen). Great for the price, but still a lower step in quality than my 50mm 1.4. Again, thanks a lot :)
I'm a newbie to photography, I bought this lens to try out portrait photography and I tried to take a self portrait with my cat and somehow as I was picking her up the tripod got knocked and down went my camera. The second time I've used this lens and I've fucked it. This looks very intimidating but at this point I'm not sure what choice I have.
If the autofocusing is not working, and the manual focus is stuck, then follow the repair instructions in this video. Also, I would highly recommend to use lens hood on this lens, that prevents this problem.
@@CamerasLensesEtc I had a go at it and for the most part it worked! But there was one part that was stiff and autofocus couldn't work properly so I opened it up to try again. And now it won't work at all again. 🤦♀️ I've ordered a replacement part but it's going to take weeks. Oh well
Have you tried to shave off 1mm of the plastic around the lens barrel I marked in the "Canon EF 50mm f1.4 USM lens - repairing the focusing problem" video at 06:06?
You saved my lens :) Thanks a ton. Reassembling the lens was bit tricky but I watched your video in reverse and that helped.
Glad it helped!

I use pure cleaning alcohol to clean the lens elements, that can remove the fungus well, if it is not eat into itself in the coating of the lens.

i have some dust on my inside back piece mirror
maybe can i do only like 13:28 ? disassembly back side only silver ring
please help
Hi! Yes, you can, but even though you can remove the ring without disassembling the lens, I would recommend to disassemble it, and hold that lens element to avoid the inner metal ring to be damaged.
What was the tool you used at the end to separate the glass? Thanks
I was using a very special, professional tool used by only professionals. :) OK, just kidding... is it a jar opener tool:
www.ebay.com/itm/254368045126

It is a "jar opener tool".
Grest video but there is something still missing and any other video on UA-cam shows how to disassembly the front element lenses to clean the dust and fungis between them
This is a very common question... my answer is that it is not possible to separate then attach the two part together.
@@CamerasLensesEtc then the only option is just buying a new one, right? Thanks!
