My 24-70 II tends to have a softer right hand side closer to infinity. Sometimes the right is just as sharp as the left, other times much softer. Even with very even subjects (let's say a building) I always notice softer right side. Only at 24mm though. In the forground though, the right side is razor sharp at the very edge. Very weird behavior to say the least... Sometimes its amazing, other times soft. Mind you, I am talking the very edge of the frame. Maybe 1/8th of the image.
Needless to say, I called Canon CPS and they sent me a prepaid overnight label and its going to them. They told me they can correct such an issue. So I sent with my body as well so after they fix the lens (if they can) they can calibrate it to my body. I just had my 5D3 there with my 70-200 and extender last week and they did a great job calibrating them together. I required something like +6 and +8 on the telephoto end before calibration, now both are at 0. My 24-70 was roughly -3 or -4 on the wide end, +2 or +3 on telephoto end.
I don't mind though... My copy is stunning end to end, and after hearing about some variations on the wide end vs the tele end, I did not want to exchange it (plus pay shipping and all that). So I will let them work their magic and see what is up, if anything. May just be some strange field curvature on one side. I know two other people so far with the same thing, except it happens on the left side for them.
I am extremely happy though otherwise. I love this lens. I just hope they can easily nudge that right side into alignment or whatever it is! Minor issue, but a little annoying for a $2300 optic.
