This is the data from Gary's tests of the 200/4 and 200/5 on an OM-2000 
with mirror and aperture pre-fire and Bogen tele support:
-----------------------------------------------------------
200mm f/4 Zuiko (multi-coated)
Vignetting = A
Distortion = none
All tests shot with the same lens, in 9+ condition. These multiple
tests were done to determine the effects of vibration from shutter
travel and the auto diaphram mechanism.

OM-2000 with mirror & auto diaphram prefire, lens supported by
Bogen Telephoto Lens Support
Aperture  Center    Corner
f/4       B         B-
f/5.6     B+        B
f/8       A-        B
f/11      A-        B+
f/16      B+        B+
f/22      B+        B+
f/32      B         B-
Notes: Statistically insignificant differences to the OM-4 test below 
[snipped out], perhaps indicating little advantage to a vertical 
traveling shutter in the OM-2000.
------------------------------------------------------
200mm f/5 Zuiko (single-coated)
OM-2000 with mirror and aperture prefire and Bogen Telephoto Lens
Support
Vignetting = A
Distortion = slight pincushion
Aperture  Center     Corner
f/5       B-        B-
f/8       B         B-
f/11      B+        B
f/16      A-        B+
f/22      B+        B
f/32      B         B-
Notes: Moderately low contrast.
---------------------------------------------------------------

This is comparing multi-coated 200/4 vs. single coated 200/5 but I chose 
this pair because both are supported the same on the same body and we 
all know that vibration is a big problem with the 200/4 and probably the 
200/5.  The differences between them are only about 1/2 a grade which 
Gary's notes say should not be considered significant without a paired 
comparison.  Unfortunately, the 200/5  multicoated test was run on an 
OM-1.  See Gary's original test data format below for more:
