This is the primary reason I placed the "Cosina" 70-210 a definite cut 
below the 75-150/4.  My observation at a Brick and Mortar camera store in 
puting one on the front of an OM-2000 when they first came out parallels 
Gary Reese's testing; noticeable pincushion/barrel distortion.  It's an 
optical characteristic I freely admit I'm finicky about and it seems to be 
a common problem with all but the very best zoom lenses.  Although the 
75-150/4 likely had at least a little, it was never noticeable in the 
architectural shots I made with mine, and I never worried about it.  To me, 
lackluster contrast is much less problematic to cope with than avoiding 
noticeable barrel/pincushion distortions in the field . . . depends some on 
type of subject material and how noticeable it makes them.
