Horrendous Front Focus Issue

Summary: I just got my copy of this lens in tonight, and it seems like I've gotten a dud. In running focus tests (paper chart), I've found that an AFMA of +20 is barely acceptable with the point I want in focus but still generally front focusing. Here's to hoping that the next copy I get is better...
Summary: This lens arrived yesterday and I compared it with my Canon f1.8 50mm and Canon f4.0 24-105mm lenses. It was not nearly as good as either of them in terms of image sharpness. Even after trying to improve things somewhat with Photoshop, the final image was not nearly as crisp as with either of the Canon lenses.
Summary: Well, I really wanted to love this lens. So much that I tried two different copies. Both had severe focus issues on 5d Mark II. First copy with such a bad front-focus that Canon's focus micro-adjustment wouldn't fix it with +20 setting. I'd estimate that something around +30 would get that fixed. Second copy front-focusing as well, but in this case I actually managed to adjust that with +19 setting, and it looked awesome!...
Sigma Firmware Required!!!! - Not a 1.4 rather a 2.0

Summary: I waited months after owning to write this review. I really wanted to give Sigma the chance to correct the mistakes with this lens. After reading mixed reviews (either love or hate) I am ready to share my experience using this on a Nikon D5100. First. The lens had major focus issues. This is something sigma will not admit. We sent the lens to a Sigma authorized repair center in AZ where they confirmed the focus issues.
Latest copy purchased 2012-July still out of focus- Canon 50mm F1.4 is better

Summary: I am not a pro but serious about photography enough trying to become one. I tried this lens on my Canon Mark iii and compared it with my new 24-70L 2.8 lens. The Sigma back focus as many has claimed, my 24-70L even at wide open for this lens has no focus problem. I have no reason to keep this lens other than the better Bokeh it can create at 1.2. I got to say the bokeh is very creamy and delicious but the out of focus problem just drove me crazy.
Summary: After trying 3 different copies of this lens (Canon), I'm giving up and returning it for a refund. ALL THREE had severe auto front-focus. They were so far out, the camera's focus adjustment couldn't even bring it close. Sure, it focuses fine at 2.8 or greater, but that's just because the depth of field at those apertures hides the front-focus.
Summary: I just received the lens today, and I've already decided to return the lens. I love the build and construction of the lens. It's big and feels pretty good even on my T3i/600D...if just slightly front heavy. However, the lens is obviously front-focusing. I know that many people here might use manual focusing or have a higher model Canon/camera where they can micro-adjust the AF, but I can't on my T3i/600D.
Summary: I just bought this lens on Friday. I shot it right out of the box and noticed it had some focusing issues. I took it to my local camera store and they calibrated the lens with my camera the best they could. It was at my 7D's limit for correction. I shot it all day saturday at a wedding (not a paid gig) and it performed very poorly. There were many missed shots and the lens was searching in the church almost every time I used it.
Summary: I really wanted to like this lens. The 77mm filter is great, and the build quality O.K. Certainly not Nikon quality, but passable. The lens required a plus 20 setting on D300 to bring close up items into semi-sharp focus. Manual focusing was so far off it was pathetic and totally useless. Portraits were horribly soft when using AF and the adjustment. I can't trust this lens, which I planned to use for wedding work. So it's going back and I'm looking for another option.
