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!

THANK YOU for this guide. My 1.4 lens was stuck not focusing closer than 0.6. Your guide made it so easy to follow and my lens apart without that much fear. After reassembling I have the full range of focus back on my lens!

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

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!

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.

[calebknopp]

Thanks! Got my newly purchased lens in good working order thanks to this video!

[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.

So beautifully done. Concise. Clear. Smart. Glorious!

[annieharper]

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!!

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.

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!

[ronchristensen]

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!

[elthumbz]

First time attempting something like this! Worked like a charm. Thanks!

[jorgenleangen]

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!!

[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. 📸

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.

[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!

[rtpettway]

Great video!! Sanding the guide rails was a perfect idea! My lens works again!!! Thank you!!!

[johnpennel]

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 🙏🏻

Awesome video. My 50 is back in commission!
