I haven't tested the EF 50/1.2L vs. OM 50/1.2 for focus shift, but it's
clearly apparent on the EF,  but I haven't seen it on the OM.  IMNSHO the EF
50/1.2L is a let down, particularly considering the excellent ~50mm lenses
canon has made in the past (FD 50/1.2L,  FD 55/1.2AL, EF 50/1.0L, etc.)

It's not hard to conceive of how it could be the case that one shows it and
one doesn't. Significantly different optical formulas have different
characteristics...   (asphericality has nothing to do with focus shift per
se, btw.)

re: MF/LF -   the 110/2.8 RZ lens is pretty common,  the 110/2 Hassy lens
while expensive is not uber-rare. There's an 80/1.9 Mamiya 645 lens that is
common and cheap. There's several 4x5 lenses in the f/4.5 range or even
faster (Aero-ektar f/2.5 comes to mind... That's what, about f/0.5 in 35mm
terms, wide open?) ... So, several options I'd say. Some cheaper than OM
50/1.2 even.  Granted, the portability is much less, but the image quality
will be even higher (given the large film area).

Some sort of Graphic (speed, super, etc.)  with a Kodak aero ektar f/2.5
would be a kick-ass portrait rig, I think.

I do like the sizes of the zuikos. Impressively small. If you think the EF
50/1.2L is big, try the 50/1.0L.... That thing is bigger than the *box* the
OM 50/1.2 comes in(!) and then some...

It's nice to have so many choices for fast 50s out there.
