I, too, have not worked with the 90, but I would find it hard to believe you
could improve on the quality of the 100. An amazing piece of glass and
metal. I have an older 90 and it sees use only if I want a ligher load,
know I am not going to need to focus closely, or know I will have to focus
fast on moving objects, Perhaps the 90 APO has such advantages over the
100, but as I said, I find it hard to believe any advantages on optical
quality would be noticable. Maybe others have actual experience with both
lenses. I,too, would like to hear from them.

Hi Barney,

It is a dream lens in most respects. Its macro qualities are excellent, and as you have expressed an interest in that capability, it's an easy choice. I doubt that the difference in focal lengths between these two lenses would make much of a difference for your portrait shots.
What I'd suggest is renting each from your camera store and spending the weekend shooting a couple of rolls. That should answer your question definitively.
