I have used both the 50/3.5 MC and the Tamron 90/2.5 (52B, with 49mm
filter thread) for lots of flat subject copy work and been pleased with
the results. I'm sure there are other lenses, both Zuiko and third party
that would work well, but my personal experience is limited to these
two. They are also two of the more reasonably priced lenses for this
purpose. I've never felt any need for something else for such work.
I generally worked close to f8. At middle apertures, both have excellent
sharpness and nice flat fields.(Not to say they don't at other
apertures, I just didn't check.) Contrast and color depends a lot on
lighting. I worked mostly with Ektachrome 160T and flood lights.
Contrast seemed normal. Color was perfectly adequate for the purpose of
projecting in university classrooms, where projector, lighting, screen
color, etc. introduce all kinds of variance anyway. For accurate,
repeatable color, I assume flash would work better, as floods change
color temp as they age. They have the advantage of simple setup to avoid
reflections and simple exposure without a lot of testing. Since some of
my work went into the macro range where exposure compensation would come
into play, TTL metering was a blessing. I got fine exposures and overall
results from the first roll. But you have studio flash with modeling
lights and a flash meter, no?

Does anyone have any opinions on the best lens for flat work and/or
painting reproduction? Has anyone tried the 80/4 on a 14mm tube? I am
looking for accurate color, sharpness, and normal contrast.
