Yes, I could be confused I suppose. As I read the manual and work the
menus, it seems like stacking and bracketing are the same thing. Turn on
bracketing and select focus stacking. The mkiii is the same as the OM-1
for frames (15 max). The capture consists of an ORF+jpg for each frame of
the quantity selected and a composite jpg of the stack at the end of the
capture string. Quite brilliant, and I guess you could cull the ORFs you
want and stack them in software. But no need to, for me at least, at this
time.
Anyway, I must be missing something.

It does seem like we're talking about two different things. Maybe as I
learn more, I'll figure it out.

I'd like to get the 60. I'd also consider the PL 45, provided I could
focus stack automagically with it, otherwise there is no good point in the
PL. But I assume it works with Olympus FB. But I feel certain that I
would use the 100-400 much more.
I don't think I'd mind the tripod mount as the DZ 50-200 is similar. The
foot of the mount I generally rotate to 11 or 1 o'clock, where it's out of
the way of my hands when I'm using the lens and serves as an extra handle
when I need it.

I'm actually surprised that you carried tripods, as I assumed you no longer
used them once you got a digicam! I recall your championing the 5D because
of its relatively good handling of noise at high(er) ISOs which made
handholding feasible most of the time (or so the impression).

Life is good! Thanks for sharing, as always.
