Never had a problem with my 50mm f1.8D yet... I have a very stron opinion that Canon lenses are total crap, as the FD won[t mount on the DSLR/SLR and even some SLR wont mount on SLR and Even some DSLR wont mount on DSLR with Canon. Canon plays the money games, and as far as i'm concerned, investing in optics is yet another short lived Canon investment, as they will someday find another way to introduce incompatibility. I havent found a problem with my 18-55, 55-200, 50mmD or 50mm f1.8, my 50mm f1.4 pre-ai, or even my horrible 43-86 pre-ai super flare nikkor. Try using your FD mounted Boat anchors on a modern/relevant camera

Ken Rockwell bitches that the F100 has a brass lens mount... I looked at a Canon SLR of the same year... Plastic lens mount, plastic lens reciever on the camera... Plastic crap.

The Confederate States of America would be offended to have such poor craftsmanship called a "rebel"...
