When I say “bending back into place”, I’m referring to the black focus ring. If you have the same problem that I did, you will notice that the focus ring is bent outward at it’s narrowest point. You will need to do your best to both bend it back into place while not bending it too far. If you do, it will pinch the little white plastic glider in the focus ring slot causing the lens to jam up.

Does that make sense? I hope that helps!

Thanks for the steps! I’m going to try doing this to my 50mm soon.
One question though, I dont understand the “bending back in place” thing. The photos of the white plastic thing are not clear, can you exmplain more? should I tighten the screw on the white thing? or just try to squeeze it back into it’s track? or what should I do? I guess I’ll understand once I actually open the lens and see it, but just wanted to ask if I’m missing something.

Thanks again

I have tried two copies of this lens. My complaint is that the focus ring is not smooth at all. It this normal for this lens. A $100 lens shouldn’t be this rough. Thanks Jeff

I had the exact same problem, lens was dropped in a bag from about half a meter, onto concrete, person carrying my bag didnt know about the lens :S but i followed this and was able to bend the focusing ring back into shape with ease, makes me wonder if canon simply used a stronger material, this would never happen

thankyou

I ran with your advice and the stuff from those forums. I had the same problem where my focusing ring was bent. After bending it back and putting everything back together I’m happy to say it works like new. Thanks a lot!
