thanks for the explanation. need to mull it over some more to fully understand all ramifications.
especially why i notice the phenomenon of "too small af marker boxes" at times on EOS M (1st gen), but not really on the 5D3. some combination of aps- c vs FF sensor, slower EF-M lenses vs 5D3 on which i generally use f/2.8 lenses or faster) and/or differences in scenes i capture with the 2 systems.
will also be interesting to find out whether EOS M50 with DP-AF and more AF points brings an improvement in practical terms in this regard.
i picked one up just yesterday - funnily and totally co-incidentally exactly at the time when it was questioned here, whether i still qualify as *current* Canon customer at all or just as "dry dock Cano-whiner". M50 is actually for my daughter and she too has noticed the af boxes on EOS M (with 22/2.0) not always matching af-sensitive area. if she does not complain about the issue any more, i consider the issue solved ... no matter how it may have been accomplished in the face of "unforgiving laws of optics".
