Sigma客服说可以相机镜头一起送过去重新calibrate。于是我问Can this problem be
completely fixed by re-calibration? What if I want to use the lens on
another camera body, would I need to redo the calibration?
客服回答Its almost a total impossibility for two different bodies to exhibit
the same issue. The lenses are calibrated to a specific standard all the
time and its normally the body that is the issue believe it or not. If the
second body is also out of adjustment you can do a small tweak with micro
focus adjustment to make the lens perform the same as the calibrated lens /
body combo.
他说的可信吗?
