The longer focal length means that the DOF is much thinner with the 90mm than
with the 50mm. So, the images will pop in and out of focus much more
aggressively. (you should see what happens with the 180 mm APO Telyt !!) I have
both lenses and, on film, I find it hard to choose one above the other. On the
other hand, on the MTF graphs, the Elmarit does noticeably better. To see the
difference in actual use, I'm sure that one would have to use each lens on a
tripod and then compare the results side-by-side.
Basing your judgment on sequential use of the lenses would tend yield a more
subjective opinion of their performances.

Subject: [LRflex] 50 Summi vs 90 Elmarit Discrepancies
Hi Group,
I'm noticing a 'trend' in my shooting where my 90 Elmarit consistently is
outperforming my 50 Summicron when I'm shooting. Through the viewfinder of my
20D the 90 'looks' sharper, contrastier, snappier, images even on the camera
LCD look better with the 90 than the 50, and doing RAW conversions on the home
computer the 90's shots always edge out the 50 when it comes to contrast, micro
contrast, sharpness, snapiness, "__insert variable here__", the Elmarit 90
always is edging out the 50. Period.
Is this what I 'should' be seeing when comparing a 90 Elmarit R to a 50
Summicron R?
Note: The Summi is NOT turning in bad images on any measure I can find -
they're just edged out by the Elmarit routinely - consistently. Even in the
viewfinder.
