I sent my 50mm f/1.4 into the Canon shop over christmas for the usual autofocus problem. $125 and two weeks later it came back better than new, and I've been having a blast shooting with it.
This morning it's a little slick out on the sidewalks. I make it 99% of the way to my train station (a 10 minute walk), but just before getting there I slip and land on my butt, camera bag hitting the ground too.
After getting inside and letting the camera warm up, I pull it out and.....the 50's fooked again It's even worse than when I sent it in before - I can spin the ring, but nothing moves and when I shake the lense I can see the rear element moving around. Also bent the step-up ring on the 28mm, but everything else appears to be working fine. Looks like the money I was setting aside for a new lens will again go to fixing this lens. At least it was the 50 and not the 10-22 that took it.
