Oh. Hmm.

Ive set MA in at least a dozen L lenses in the past few years an with the exception of a lens body and 2.0TC the combo calibrated together by Canon, all the others required MA and it was quite noticeable in every case.

In addition to that, several years ago I searched through seven 24-70 lenses to find the best lens of the bunch. What really became clear was that the lenses that MA was difficult to set or see the difference were all very soft lenses.

People who claim none of their lenses require MA either have crappy lenses, had them calibrated previously or are extremely lucky.
