RE: [Leica] 75 F1.4 vs. 90 F2 Apo Asph: Best with M6?

[Dan Cardish <dcardish@microtec.net>]

If you are interested in seeing how the bokeh of the APO 90 compares with
the 75, check out my Leica page http://www.kelvin.net/leicaman/ and click
on the 'portfolio'.  

The last photo on the last line is with the new 90 @f2, the first three of
the last line were done with the 75 @f2.8.  Also, the 2nd photo on the
first line was with the new 90 @f2.

I haven't worked on this page (http://www.kelvin.net/leicaman/) in months.
In reality, what I call my portfolio is in actuality just some images used
to show the qualities of typical Leica lenses.  This eventually will be
called my 'Leica test photographs'.  I've also been meaning to get a better
photo of my Leica's  ;-).
