Can't see 5 lens being wrong !! I think its more likely to be the body.
The thing is, I have tried them all on not one, but THREE bodies. Two 5d mark iii's and a 6d.
Identical behavior on both 5d's and the problems are different on the 6d, generally less pronounced.Sure, it's possibly that my friend and I both have crappily assembled 5d's. With a canon 50mm 1.4 the focus is spot on with my 5d iii with all points, though, but with my 85L there's a VERY slight front focus shift with outer points kind of like what the sigma art is doing, but much, much less severe which is why I've never noticed it before.
This 5th copy of the sigma are is terrible even with the center points and needed hours of tinkering with my sigma dock to get it working somewhat consistently (with the center points). Did nothing for the outer point problem, though.
And yeah, the IQ of this lens is worth it, but having tried 5 copies I can assure everyone there is definitely noticeable sharpness differences in different copies, they aren't all that amazing. The sigma 35 and the 85L wide open are still sharper.
