I've got one in my bag and it is one of the more UNDERRATED lenses. I put it head to head agains my M645 80mm/4 Macro and against my M645 150 2.8 A. I was hoping to find justification for 'kicking it to the curb' but instead I found good reason to keep it.
The Zeiss microcontrast is alive and well, especially as you move toward the shorter end. It gets a touch softer when you go longer nearing the 200 range (what zoom doesn't). Check out the MTF's at pebble place and you see what I mean at the 80mm range. It is not quite the same as the best Zeiss primes, but for $200 you sure are close enough (imo).
I can definitely recommend it ... especially in the 80mm-135mm range where it performs best. I had been getting some pretty good 3D-ishness out of my M645 80/4 in certain applications, but the 80-200 gave even more when I went head to head in a 3D shootout for myself. Kinda reminds me of how the Zeiss 35-70 is a zoom that totally rocks on the short end ... besting many primes ... and the long end is still plenty good, even if a bit slow, complete with Zeiss looks (maybe to a bit lesser degree than some Zeiss primes).
200 ... play it down and offer 150, but 200 for new would still be quite nice.
