7d: MFA before (FW 1.25) and after (FW 2.0) - many lenses
Aug 10, 2012

here is my list of various AF Canon and III-rd party lenses - with one
exception of the Vario-Sonnar 24-85 (Contax N-mount, converted
to EF by Conurus), none did show any change of necessary MFA
before and after upgrading the FW from 1.25 to 2.0;

additionally there are many adopted MF-only lenses - which also can
benefit from MFA confirmation, after all the only diff. stems from the
force which drives focusing cam; here the situation is a bit different;
but it simply can't have anything to do with any possible change in
AF algorithm = non-applicable :P,

so, after a lot of work I now have a lot well MFA'ed lenses - good to
have their working condition confirmed. The speed, accuracy of AF
seems to be better - esp. in low light, and there certainly is much less
hesitancy (One-shot as well in AI-servo, I didn't test anything in AI Focus
yet).
