I got to 2 minutes into the video and thought..... there's NO WAY I would ever get this all back together again! great vid but beyond me lol

[@Jackzira]

After having my 50mm sit around for many years not functioning I decided to follow this tutorial and found out I had the same problem. Super easy to follow guide and my lens works perfectly again. Thank you so much!

[@takeapart]

perfect! happy to help….

[@serinawyman]

Thank you so much for your guide. I bought the lens without realising it has autofocus issue. I followed the steps in the video.
The step that took the longest time was filing to make the gap bigger. It took 4 times repeating to file, place the screws back, turn the barrel and repeat. before it was sliding smoothly. The autofocus is working now. All done within an hour. Thank you for creating this video!

[@takeapart]

thanks for watching, and your support

[@FlyHighWavesSounds]

Just finished mine. A big thank you for sharing this. My lens got stuck and had the focus issue from long time. Was fun doing it and happy that is working again and like new. 📸

Bro I knew thirty seconds into your video that this project was over my head but I couldn’t stop watching really in awe at your ability. Nice man and thanks.

[@takeapart]

thanks for watching

[@roarjohnsen]

Worked for me too, the lense had just been collecting dust for many years. I even had the official service partner of Canon in Norway to check what was wrong with it a while back. They concluded that it was more expensive to fix compared to buy a new one. Thank you very much for the video, easy to follow and it worked perfectly on the first try after assembling it.

[@takeapart]

glad to hear! thanks for watching 🙏

[@benzprivateworld8430]

Thank you. You made my lenses work again. You are a hero to all of us who came to see you. Hope you can help us solve many problems.

WOOW - I actually did it - thanks to your perfect tutorial - I was lucky that it was the same error on my lense :) Did the repair in the same matter also - perfect!!!! Thank you so much for creating this video - now i have a great lense again :) And you got yourself a subscriber for sure!!

[@takeapart]

thanks for watching! Im happy that it worked for you!
enjoy your lens ...

[@johnpennel5586]

Amazing … had to take it apart twice and the 2nd set of sliders were really sticky after trying to flatten the focus ring, but my lens is now working a treat! I was about to buy a new one after my local photo shop said it wasn’t worth sending it off to Canon to get fixed. Thank you so much for this excellent video 🙏🏻

[@takeapart]

thanks for watching and I’m glad that you fixed your lens!

[@PangazShed]

Great video! I had a sticking focus ring also. Instead of using a wooden mallet, I got a sheet of 1000grit Wet and Dry paper, layed it on a flat surface and carefully rubbed the distorted side. This worked for me. Also easy to follow video, thanks very much!

[@takeapart]

thanks for watching and tip!

[@crimsonsmirk]

Thank you so very much! Большое спасибо! You have saved me hundreds of Euros with your helpful and detailed tutorial.
Also, for everyone trying this, I cannot stress enough the importance of that last step that's checking if the white sliding bits can run through their lanes smoothly. I found out one of them was getting stuck super easily in one of the lanes (while going through the other easily), so I filed the former with a regular metal nail file until it ran almost as smoothly there as in the other and now it seems (fingers crossed) this lovely lens is completely fixed!
I'm so happy! The nifty fifty is my favourite and I have dearly missed its splendour.

[@takeapart]

thanks for watching

[@annieharper9069]

ah thank you for this video! my camera would not focus with my 50mm and after watching this, i took my lens apart and learned that the problem was it was a broken slider. i fixed it up and my lens is good as new! i saved myself a couple hundred bucks and i couldn't be happier!!

[@takeapart]

thanks for watching!

[@tankurttekin_]

Thank you very much! I wouldn't have repaired my 50mm f1.4 without your video. Because that alloy part seemed alright to me in the beginning and the deformed part looked like a factory design curve. I used your Russian method to align that part with a wooden stick and a bamboo chop stick to maintain the thickness of the canal. So I didn't have to sandpaper it to proved smoothness. I am so happy because I saved my dear 50mm lens and it works perfectly again. Thanks again!

[@takeapart]

hi, perfect! thanks for watching …

[@monsrigi89]

Thanks a million for this awesome tutorial!! I found exactly the same problem with the bend in the alloy ring and was able to fix it.

[@takeapart]

happy you fixed it! thanks for watching

[@ronchristensen9832]

Very well done. Just finished mine. At first I thought the same thing, that it looked a bit complicated. But once I got into it, it wasn't so bad. The trickiest part for me was getting everything lined back up while putting it back together. But the video was good enough I could find some landmarks on the rings and it went back fine. Very well done. Thank you!

[@takeapart]

Thanks. Mine had same issue and your guide helped me fix it.
Bad design flaw as a light knock to the front of the lens can cause the thin alloy to bend out of shape. Got a working 50 again now.

[@takeapart]

well it is hard to explain... I will try ... try different lenses and if you get better focus score than the first lens has some issues... or if all your photos has missed focus than it is most likely the lens ... thanks for watching

[@Fjalll]

The lens got stuck at close focus distances because the sliding mount was bent out of shape as the one in the video. Followed the tutorial and it's working fine now.

[@takeapart]

perfect! happy it help

I would be terrified to try this, even though this very well could be the issue lol

[@berica123]

Thanks a milion! Before i looked at your video I was afraid even to look at the lens, but today I said to hell with it! What's the worst thing that can happen if I slam it with a hammer! LOL! So I did! I took it apart four times before I got it right. Now I need four and a half minutes to take it apart and put it back again! Hahahah! Think I'll name it Nifi (nifty fifty)! And, yeah, it is almost 15 years old and now it works like new one!

[@takeapart]

glad to hear! thanks for watching!

[@OutraPerspectiva]

Works like a charm, the focus ring is great now but autofocus stop working :/ Aperture still works, when push the AF button camera recognize that AF is on but the motor don't show signs of life.

[@takeapart]

hi, thanks for watching, please check connections inside the lens ... you may forget to connect something. :-)

[@JakeLewisReal]

Did you end up figuring out the problem?

[@khaimai2271]

How to know the sliding bent has problem? And what tool i should use to fix that bent? I have the same issue like you, and I tried to open the lense, follow your instruction to open it. However, I dont know how to look and regconize the problem from the sliding.
I appreciate if you can write me some details

[@takeapart]

it is common issue …. you have to feel it once you have all apart make sure that it slides nicely without any restrictions.

[@DmasterGm3r]

Hi Men, I got lost in the step where you removed the plastic ring, mine does not do that how do you do it
