sometimes original makers' lens will also need to be caliberated..... its not an uncommon thingy....
get a body with micro adjustment? then you can do the cali urself..
I was in the same situation as well, deciding between the two and finally last week I have gotten the Sigma. Well, over the weekend, brought it out for some fun and I was satisfied.
With issue of front/back focussing, well, MA could assist alittle...but do remember to test several copies at the shop the you want to buy from..
This photo was taken with a Canon 5D MKII + Sigma 50mm F1.4 @ 1.4, 1/100, ISO800
