Im really interested in picking this lens up to use with my canon 5d. Banannaraws shots have completely sold me. Now I had the 30mm for my 60d and loved it, had no focusing issues with af at all. I see here that the quality control on the 50mm isnt that great. My question is,let's say I get a copy that does front focus or back focusing af. Would it kill the deal if I didnt bother with af and stuck to mf? I'm planning on possibly picking it up in a couple of days. I'm chasing the sigma more than the canon bc I love the bokeh it creates. If it's that much of a hassle I guess ill consider saving a hundred dollars by picking up the canon version. Any insights would be greatful!
If you get a Ee-S focus screen to go along with it, then no, it shouldn't be a problem... manually focusing that is.
Also, you can get the lens calibrated(free if the lens has a warranty), if it does have focus issues, or even replaced, provided you buy it new.
