You inspired me to go the same route. I bought the repair unit from ebay and fixed my lens. Your video made me think it was not so hard, so I decided to give it a try. So far working as butter! Thanks man!
I just fixed my 50 1.4 usm, it had bad "dent" problem on aluminium cylinder part. Now it focuses very smoothly and easily - manually. But for some reason, AF is very slow! Looks like AF micro usm motor is faulty. All gears are moving quite freely by hand but AF motor is having problems to turn the AF mechanism.
Thanks Sharikov, I hope it's easy to replace the motor as I saw on your video. My lens can only focus on objects that are close but once I point the camera to focus on far object the lens won't adjust (I only hear clicking sound) as if the motor can focus back but not forward.
How do i confirm that this is the fault with mine? How did you confirm it was with yours? I tried the barrel replacement method before and it didnt work.
Thank you for helping me understand how to do it when I fix it. Can I ask you where did you find the replacement? Because I can not find the spare part on e-bay. Thank you very much. Alberto
Thank you! It's hard to tel without taking the lens apart.. It might be the same problem as I had, and it also might be a DENT in the Cylinder (the one I take off on the 3:20, the one with the AF drive on it). The DENT does not allow the Glass elements to slide back and front while focusing! It might be fixed by just bending the aluminium cylinder back into its original shape! Hope this helps!
Люди все равльно сделать самому!!! Но основная проблема у этих объективов геликоид, его нужно всего лишь поправить об ровную поверхность. Поэтому рекомендую не снимать бленду. Со шлейфами под баойнетом можно поступить проще - выкрутить 2 шурупа из байонета, которые держат контактную площадку; приподнять байонет и изнутри отжать отверткой пластиковые ушки (одно хватит), они держат черное кольцо которое в свою очередь распирается и поддерживает линзоблок и контактную площадку.
It does sound similar to what I had, althought I had blindspots, @45cm and@1,5m focusing distance, where the AF drive would loose grip becouse of the chipped sprocket.. I would take the lens apart first, before buying the part!!
Sorry man! Have no idea! All the glass elements come of as a hole unit, didnt really think about taking them apart, as I was lucky enougth to have no dust in there..=
Got it of Ebay! Just tiped in Canon AF drive 50mm and picked the best price.. I got it from the UK version of the site, and the seller (Canonspares) is still selling this part now! Just check that its the one for the right 50mm canon lens before buying!!! Hope this helps!

Thanks for the tut! I'm about to order a new drive, have you had any issues since this installation?
Thank you!

So actually that little gear is all that's needed to replace. Just a 5c part causes all of this damage, when it could have been brass for a dime more.
+hughtub i know right? like WTF canon fix that shit
Like the song at the end, reminds of me early pc gaming days when I was a little boy
Glad I could help! :)
Great video! Was the AF drive a Canon one?
Nice video. question though, do you need to calibrate the lens after this?
I calibrated in camera with a ruler, but with a 50mm proper calibration never hurts :)
May I asked which Ebay seller did you get your AF drive unit from?
It does sound similar to what I had, althought I had blindspots, @45cm and@1,5m focusing distance, where the AF drive would loose grip becouse of the chipped sprocket..
I would take the lens apart first, before buying the part!!
Sorry man, haven't got one of those, use primes mainly!
Hello. Can you record a video opening a Canon EF 24-70mm f/2.8 L ?
Sorry man! Have no idea! All the glass elements come of as a hole unit, didnt really think about taking them apart, as I was lucky enougth to have no dust in there..=
