Hi All,
I just wanted to comment that I think the 20mm f/3.5 that I received
from Clay
is an incredibly early (and, consequently, rare?) version. It's not
multicoated (i.e.
no "MC" marking).
My OM-1 manual, which dates from 1974 or so (i.e. it pre-dates the
existence of the 21/2.0 and
50/1.2 lenses) already refers to the 20/3.5 "MC" Macro (along with the
80/4.0 MC macro, also manual
diaphragm) lenses. So - this means that only from about 1972 - 1974
were these very very early
single-coated Macro lenses made?
Quite special indeed... I also love single-coated lenses for B&W work,
and I must say, the quality
of the 20/3.5 (on all aspects of image quality) is stupendously good,
as long as you use the lens
at relatively wide apertures. Have not done scientific testing, but
from images I actually get the
impression that wide open it's already at peak performance.
Oh, and another question - what do you guys do to tame vibrations from
an OM-1 when using a lens like
this for natural-light work? (i.e. shutter speeds anything from 0.5 to
20 seconds) ? I thought my
old Linhof tripod was reasonably solid, but even with mirror lockup,
at these high magnifications the
image is jumping all over the show, almost impossible. Thus, am
generally using flash for the moment.
Is the answer some über $1000 tripod??
