I agree with what you say - but I notice that the image at
www.coldsiberia.org/animal/standing_horse_no_USM_in_scanner_8bit_850.jpg
is a bit soft on the left side compared with the center (and
the right side - which is a bit soft at the far edge and lower
corner). I'm always surprised when people find lenses
sharp that have obvious deficiencies in alignment or
corner/edge performance...;-)
