That's true. Lens "sharpness" can be subjective. Many times an
impression of sharpness is really caused by high contrast, or "pleasing"
contrast, or even subject matter: I can take expose adjacent frames
with the same lens and settings, but the subject on one may appear much
"sharper". My "worst" lens--an old no-name screw mt. 105mm--has very
poor contrast and delivers what look like soft pics. But if I look
carefully the lens resolves detail quite well, the same really as my
Ziuko 100/2.8
I think that contrast is a more important variable in image quality.
You can use it creatively, say, by using a soft lens in harsh lighting,
and a high contrast lens in very subtle, evenly lit scenes. The Zuikos
are especially well suited to the latter, especially the 50/2, and I'm
sure the 100/2 . . .(which I've never seen!)
