It's already been done. Check out Gary's lens tests for the 2 lenses <http://members.aol.com/olympusom/lenstests/default.htm>. Gary is careful to point out that only whole grade differences are valid in comparing 2 lenses (except in a few paired tests). Applying that rule, one can clearly conclude that the Tamron at 80mm is at least as good a performer in both sharpness and contrast at every overlapping f-stop as either of the 2 MC samples of the 85/2 that he tested. Based on the consistency with which it outscores the 85/2, I suspect the Tamron is slightly the better lens overall with the particular samples involved and under the specific test conditions.

Walt started all this by suggesting the Tamron as an all-round solution to the 85/2 vs. 100/2.8 (and to stir up a little action- satisfied Walt?). The Tamron is certainly a great lens, but I would never think of it for portrait work except in a fixed setup with a tripod. It's big and heavy and has a completely different feel than either of those small, light Zuikos, like carrying around a couple of extra bricks. (Yes, Mike V., you CAN hand hold it. I guess I could, but I use a monopod.). Wandering around pointing that thing at people in a casual portrait situation would probably send some running in fright!

They are both great lenses, capable of exceptional image-making, but quite different beasts. Why does one have to be best? How could one even know? How about about tests at 1:10, 1:15,,,,1:100...infinity, all duplicated for flare vs. non-flare light, low vs. high contrast subject, hand held vs.sturdy support (particularly appropriate here), wth and without teleconverters, extension tubes, etc., etc..................... What a colossal waste of time!!!!!!!

Moose stepping down from soapbox

would anyone be prepared to put up their two bits and show conclusively that
the Tamron zoom is sharper than an 85/2 and under what conditions? My MC
85/2 is a stunning performer but to have an off brand zoom outperfom it
would be a real eye opener.
