The slides were awesome; very crisp indeed :~)! At that time, it was not in my budget; later on I opted for the 70-180 Vario APO Elmarit, which as you know, is a top performer. In the BAS report on R lenses, July 1996, page 23, there are sharpness & contrast diagrams for f2, f4 & f8 from the center thru the edges. What's amazing is that the lines are almost coincidental & straight across; a quote from the test is as follows: "Both at full aperture & stopped down (test apertures f2, f4, &f8 ) the lens offers almost the same incredible optical performance". The header statement for it's optical performance is: " Virtually uncompromising apochromatic correction......A lens of superlative quality ". The only other lens in a similar focal length/speed, that is as good, is the Contax Zeiss 200 f2 APO Sonnar; per tests that were done by a German photo magazine. I'd say, if you want this gem; go get it ;~)! Tom D.
