In fact if i read mtf tests before buying a lens, it is only in order not to waste my money, not to split hairs. For the apo 90 and the old 90 at full aperture, the tests made by CDI give the same results : good (center), good (edges). So I concluded that the apo is not an absolute winner. At 2.8 , the apo gives : very good, good and my elmarit : good, good.The old summicron : very good, good. So the apo is one more time only equal to the old summicron and both the summicrons are (slightly) superior to the elmarit. I expected something better with the Apo. >> Thanks so much for the illuminating study of the old Summicron vs. the new 90ASPH Summicron. The advise suggests that if one has one of the pre-ASPH Summicrons and shoots primarily at 5.6 and 8, so there is no reason to speed $1,900.00 for a new lens that won't provide any improvement. Thanks again. Don R.
