The difference in 'sharpness' at any common aperture isn't huge between these two; certainly not as big as that between the old 50 Summilux and the new ASPH, but the rendition difference is quite marked. There is a place for both lenses and I don't think I'm willing to give up that difference. At f/2 and f/2.8 the new lens has better mtf results, by by f/4 you'll be hard put to tell the difference. I have to say that most of the time I like the pictures the Summilux produces better than those of the Summicron, even though I carry the Summicron more due to the size. And f/1.4 can often be useful. -- * Henning J. Wulff /|\ Wulff Photography & Design /###\ mailto:henningw at archiphoto.com |[ ]| http://www.archiphoto.com
