[Leica] Apo and asph: pros and cons

["A S Jordan" <andrewsjordan@worldnet.att.net>]

We have been excited for many months about the aspheric series of lenses for
the Leica M and the apochromatic lenses for the Leica R.
On the one hand, many improvements have been noted compared to the older
designs. On the other hand, some users have commented on the extreme
sharpness of the 100mm f2.8 Elmarit R that is a drawback in portraiture and
the lack of "bokeh"  with the 35mm f1.4 Summilux M. Since most of us are
interested in upgrading our photographic tools it would be interesting to
hear from users as well as optics experts about the pros and cons of these
new designs. I hope this will stimulate some timely discussion.
