Agreed.
To start with, here's Gary Reese's lens tests for both lenses (as MC examples
-- I'm sure that a new 85/2.0 SC is no longer available; these results are
available at http://members.aol.com/olympusom/lenstests/default.htm):
***** Lens test results start *****
85mm f/2.0 Zuiko (multi-coated); OM-1 with mirror lockup
Vignetting = B+
Distortion = slight pincushion
Aperture Center Corner
======== ====== ======
f/2 C+ C+
f/2.8 B+ B
f/4 A- B
f/5.6 B+ B+
f/8 A- B+
f/11 B+ B
f/16 B+ B
Note: Moderate contrast.
100mm f/2 Zuiko (multi-coated); OM-1 with mirror lockup
Vignetting = A
Distortion = none
Aperture Center Corner
======== ====== ======
f/2 C+ C+
f/2.8 B- B-
f/4 B B
f/5.6 B+ B
f/8 A- A-
f/11 A A
f/16 A+ A
f/22 A- A-
Note: Exceptionally high contrast images with exceptional
image detail in low contrast range details; remarkable lack
of vignetting wide open.
OM-2000 with mirror and aperture prefire, same lens as above
Aperture Center Corner
======== ====== ======
f/2 * *
f/2.8 B- B
f/4 A A-
f/5.6 A A-
f/8 A A
f/11 A A
f/16 A- A-
f/22 B+ B+
Note: * = not available. Moderately high contrast, except
moderate at f/16 & f/22.
***** Lens test results end *****
Hokay, so now the numbers are done.
Buy the 100/2.0. ;-)
Seriously, I've never had the opportunity to use the 85/2.0, but I've been
stunned by some of the images coming from my 100/2.0 (stunned in a *good* way,
I mean). I'm also not sure I agree with Gary's test results for the 100/2.0
based on his letter-grading scheme, but what the Hell -- he's a lot more
thorough than I am. The 100/2.0's a wonderful lens, IMNSHO.
