Multicoating could indeed be an issue. Flares could be terrible if too
much light was bouncing off the specimen mounting plate.
One site I found describes the resolution of microscope optics as fairly
uniform across brands and time, but dependent on glass technology. The
three major classes of tech are "Plan achromat", "plan fluorite" and
"plan apochromat". The apochromat seems in general to resolve twice as
fine details as do the achromat, with the fluorite in the middle.
I suspect the microscope objectives will have the edge over camera
optics at higher magnification.
Btw, you may want to check this (awesome stuff) out on occasion:

He apparently use a microscope objective mounted in front of another
photographic lens.

I have now worked through five of the old 4X microscope lenses Mike W.
brought me, and found that none of them can match the detail resolution
of a reversed Pentax-M 28mm f/2.8 stopped down to f/5.6. The Pentax is a
little soft in the contrast rendering, though, so maybe the A-series
edition is better.
Most of those lenses will predate (in design if not manufacture) the camera lens
and I don't think any of them will be multicoated.
To explore further options, a Pentax-K 24mm f/3.5 has just been ordered
through eBay. :-)
Interesting times. Another, more systematic study of the 10X lenses
coming up, but not in a couple of weeks. School has just started here,
and I'm busy getting to know my new students.
