[Leica] One way to justify a M10R

[don.dory at gmail.com (Don Dory)]

Yes Mark, with pixel counts well over 40mp on many cameras a lot of
photographers are shooting very loose and doing post production cropping.
 Shooting full frame and printing with filed carriers was an important
discipline when film was grainy and many lenses were not so good especially
near wide open.

Some lenses today(admittedly only a very few) are capable of adequately
dealing with over 220 cycles.  Most MTF's shown only record data for 30-40
cycles.
