Re: Should be avoided by inexperienced users

I agree with darklamp on this subject.

There have been many threads on these forums from beginners who have meddled with MFA when their actual focus problems were caused by technique, not body/lens miscalibration.  I have tried recalibrating one of my lenses using MFA and my experience has been the same as others on this thread - I couldn't see any difference after the MFA calibration.

MFA is relatively new and professional photographers have been able to produce great shots from SLRs for many, many years without the benefit of MFA.

Note that MFA only applies to PDAF systems as used on DSLRs.  CDAF systems as used on all mirrorless cameras (including compacts) are not affected by any body/lens miscalibration.
