- In this video I will show how you can disassemble and assemble the focus assembly in Canon FD 50mm 1:1.8 (New Version), Just in case, you want to re-grease the focus helicoid's.
My lens was actually fine in the focus, so I will not the re-grease process.
REMEMBER, when working with focus helicoid's, you have to set small marks inside BEFORE taking apart the focus assembly, and remember how many turn (s) before the threads is separate.
The repair manual will NOT show you that!

This video will save my lenses. Thank you very much for sharing this information and helping keep these lenses alive.
mine already exploded from watching another video RIP. this videos much better.
Thank you so much for posting, you've saved my lens, the reassembly part was super clear - I tried several times unsuccessfully until found your great vid thanks
amazing. I have two of this lenses. you are such an inspiration.
I had the lens completely apart without and then after watching a few other videos, I finally came across yours. I have the lens back together! The blades of the aperture seem to be a little sticky though. Oh well! I’m happy to have it working “somewhat okay.”
Thank you. Seriously saved my life/lenses!
Amazing video. I’m having a bit of trouble removing the name plate on a Canon nFD 24mm f/1.4. I tried the rubber tool with not much luck. Do you know if I would need to pop up the front ring (name plate) with a tool like you do in this video? Kind regards!
Hello. I did everything exactly the same as in tutorial (about 50 times), and everything is fine till final locking: there is no way to set two red dots in the same position - the mount rotates and blocking about 7 millimeters earlier. Any ideas what to do with this problem?
Very Informative video. I open my Canon 50mm lens couple of months ago but tried many time but not able to close it but I think after watching your video I'll do it. I'll try again in few days again.
Amigo ,thank you for more iteresting video ,with this example i repair more than 10 lenses .All the best for you from Spain.🏝 🏝 🏖 🏖
Very concise and easy to follow - was able to fix my lenses, thank you very much!
There's a known issue with canon FD lenses focus ring, that has some metal rollers with rubber that dissintegrates over time, but I watched your video several dozen times and I can't really see anything like it. Do you know this issue?
Hello Very good video!!! Do you have any video of Canon nfd zoom? I have a 35 105 f3.5 macro and I can't get it back together and get the aperture to work. It only stays wide open all the time.
Thank's Daniel, but I don't have any videos about that lens.
Hi thanks a lot for your tutorial
I had an issue with the diaph stucked , I cleaned the blades but dismount the middle and inner helicoid
Unfortunately I didn't do marks like you , I managed to set the middle helicoid and count 6 turns, then I put the middle like you and the helicoid key, but every time I test the focus, the middle helicoid go out to far and I don't know how can I fix this and I can't do focus on infinity
Thanks for the help
Hello, I have a 35mm f2 nfd that the aperature ring will not change the iris (even with adapter, other nfd lenses work). I bought this broken hoping I could fix it. Do you have any videos that might help me?
hej Kenneth. Jeg har sådan en obtik som på videoen, som jeg bruger en del, men focus ringen er desværre gået løs.. jeg tør ikke rigtig rode mig ud i at fixe det selv... ville det være muligt at få den fixet hos dig, imod betaling og forsendelse?
( hvis du er uden for københavn )
Hello, I repaired the aperture blades by myself but made the mistake to not set marks and now the aperture blades closes too far in. Do you have any tips to adjust this the best way?
Hey :) Maybe you have already fixed it but I though I'd write for other people who might have the same problem. At around 36:52 he talks about how the holes are not complete round. More of an elongated circle shape. If you fasten the screws on the wrong side of the elongated circle you will end up with a too small aperture opening. Especially noticeable at f22.
So just loosen the screws a little bit and adjust it so that it ends up on the opposite side of the hole.
Great video, I was able to fix my lens
Tengo un problema con mi lente, no están alineados los puntos rojos y por consecuente no se deja ensamblarlo en mi canon ae1 alguien sabe como puedo solucionar eso, por más que intento no puedo.
¿Pudiste solucionar el problema?
Can you help? I separated the helicoid on my Canon FD 55 1.2 SSC (non-aspherical) without having documented the angle/number of turns to remove/reassemble. Now I cannot get the focus assembly put back together :(
did you fix it? i did same with a 35mm f2
@@thurthevintagelens not yet :/
@@seanmcr6 thank you
Is this applicable to the 50mm NFD 1.4?
Great video. I've been looking at Canon FD 17mm lenses and was wondering if it's the same process to remove the front element in those. I see some that are marked down in price because of dust or haze, and as long as I can easily remove the element and clean it then I am fine.
I've been trying to search for an answer to taking apart the front lens element for the nFD 17mm f/4 and I can't find anything anywhere :/
it can only sit in one position. Jeg kan lyd en dansker fra tusind km, rigtig godt video.
Thank you!
