This was the 'sharpest' lens I have ever used or tested. On High Contrast Copy film, the 'Tech Pan' of the era, it tested between 160 and 200 lppm, the highest I've ever come across by a wide margin. It was a rather problematic lens, with severe light falloff, but it was sharp! It was amazing. Just rather pointless. All I ask for now is a reasonable balance to let the image show through, not necessarily one performance aspect of the lens. The 90 A-A is sharp enough for anything I care to do. The 28 probably is as well. So is the 35/1.4A and the 21/2.8A. I don't worry about it. The old Summaron may have been sharper. I don't worry about it. I take pictures. - -- * Henning J.
