Well, I see what you are driving at, but I feel that if the resolution is there, which it is to a greater extent in the APO 90, then it would be a question of finding good default LR3 or CS5 settings to give the pop where you want it. Of course it is great to just get the file from the camera as you want it, but not every lens can be a 50 Lux ASPH.
I think the problem is when all the different detail levels have very high contrast - at least with the type of web resize & sharpening that I know and use. A 75 Cron (and 90 AA for that matter) shot looks better at 100% than the 90 Cron V3, but once I start sharpening and resizing I\'m amplifying the finer detail in each step to be preserved in the smaller image. It tends to work well for course and fine detail, but in my experience if the mid level detail is exceptionally high the end result gets messy. You simply cram too much high (micro)contrast detail on a small area.
It\'s possible that there is some sort of PP workaround and that a clever use of multi level USM can solve it, but with my current technique I end up with images (at web size) that I\'m not quite pleased with.
That, and I think you mentioned that it never gets completely sharp stopped down, right?
It never gets as sharp as for instance the 75 Cron, but you have to engage into some serious pixel peeping to notice it. In terms of resolution stopped down, the difference between the 35/2 Biogon and the 28/2 Cron are on the same order as the difference between the 75 Cron and 90 Cron V3. It does affect the drawing style, but I don\'t consider the sharpness of the 28 Cron to be problematic, just because it doesn\'t quite reach the Biogon. On the contrary, the difference in the contrast of the finest detail give the lenses somewhat different drawing styles - which is a good thing.
