Wish I'd seen this tutorial a couple of years ago, I sent my 17-55mm off to get it calibrated as it was short focusing. Cost me around £130 !!!

@richandiben money worth spent...don't feel bad, this wouldn't have fixed your front-focusing issues. It's best Canon adjusts electronically rather than trying a mechanical work-around. Thanks for the comment.

Tried it on my sigma and worked out grat thanks. Didn't have any locktite though will this have a big affect?

[motleypixel]

@marcot64 no you'll be fine w/o locktite...good to hear your success.

Thanks. That crap in my lens has been bugging me for years. Clean as a whistle now.

I had the exact same problem with the same lens. Plucked up the courage, followed your video carefully and it worked a treat! Thanks for sharing.

i hope this works for the kit lens, cuz over here theres no techs to clean it. id have to send it to another city, and its so overpriced, im not gona pay someone to do such a simple task hehe ;)
