Apr 02, 2015 12:07 | #6 My 50 ART required no MA and is without question the sharpest lens I own. If it works great after the +20, I guess I don't see a reason to return it. 5D Mark IV

Well, the amount of adjustment is also dependent upon the body. Someone else, with a different camera, may not need to adjust it so much. Or it may take more. I have MA'd the same lenses on three different camera bodies, and there is little consistency in the settings I end up with.

Apr 04, 2015 08:26 | #10 the accuracy is what is important. you fix the lens via dock and/or send off for a warranty adjustment. A7rIII | A7III | 12-24 F4 | 16-35 GM | 28-75 2.8 | 100-400 GM | 12mm 2.8 Fisheye | 35mm 2.8 | 85mm 1.8 | 35A | 85A | 200mm L F2 IS | MC-11

Sent it in for on warranty repair and came back PERFECT at AFMA +0. Don't return to buy another lemon. Let Sigma recalibrate and fix focus. There are obviously flaws in their manufacturing but if you have a problem SEND IT IN
