In the 70's I had a 28/5.6 Summaron for a while. 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.
