Thank you. It all comes down to maximizing the strengths, minimizing
the weaknesses.

No profiles hurt by this one yet. I have a ton of work to do before
final prints are made. This one will take a while to do. I've made a
couple of test prints and don't like what I've gotten yet. OM Zuikos
are of the era where the sweet spot for them is 2-3 down from maximum
aperture. When you shoot at those apertures, everything seems to fall
in line and the images are most "ideal" to the OM aesthetic. Some
lenses do better at some focal lengths wide-open, but only in select
applications. For astro work, the OM Zuikos are really not in their
"prime".
Another factor, is that the sensor itself in the 6D really isn't all
that good. Sorry, just speaking truth as I see it. It's main strengths
for me is the full-frame format and video. I trust the 5D Mk XXIV
sensor does better, but the 6D's sensor really vignettes something
fierce and the filter stack is just odd. I can't push the processing
on the images anywhere near what I can with the E-1 and DMC-L1. After
working with about 2000 pictures from this trip, I've had to
occasionally go back to pictures from 2006 of the exact same location
to purify my eyes. Chroma noise is brutal. Where the E-3 trashes the
shadows, the 6D trashes the highlights and the shadows. I'm
mind-boggled by it.
