As I cannot find any specs on the pre-asph, you can tell me why is it more portable than the Summicron asph which weighs in at 255 grams with a 39mm filter and 34.5mm long? That seems very portable to me.

I own both and prefer the pre-aspheric because of its portability in addition to its wonderful image quality which I freely admit isn't up to the micro hoo-ha of the aspheric. It all depends upon what you, the individual photographer, wants in her or his gear.

IME, the ASPH is substantially sharper than the non-asph at 2.0, noticeably sharper at 2.8, and a bit sharper at 4.0. At 2.0 and 2.8 it maintains its center sharpness way out toward the corners, and has a higher macro-contrast at these apertures as well. I think it has less flare than the older lens, too. Erwin says it has less field curvature, but I've never noticed this - I'll take his word for it (I don't test lenses, I just use 'em). I think Erwin's report is accurate, but for my photographic tastes he understates the improvements in the ASPH. Paul
