Yes, I've found that a few of my lenses are not as sharp at
the edges as I thought they were, in particular my Pentax 35-105
f/3.5 zoom. I first blamed my scanner (Minolta Scan Dual II, 2820
ppi), but when I looked at the slides with a loupe (8X), sure enough,
the corners weren't as sharp as the centre.
On the other hand, I recently got a used 70-210 f/4-f/5.6 AF
Pentax which scans very well - better than I had originally thought.
Slides from my Pentax 35mm f/2.8 and 28mm f/2.8 lenses also
make good scans.
