Peter,

I haven't _noticed_ any light falloff on the corners of photos taken on 
a borrowed R-D1 using my Summilux 50mm at 1.4, which is not to say none 
exists. The signature look of the lens is still easily seen on the 
Epson. And I do see, at least so far, one stop difference in exposure 
time between f2 and f1.4. And all of the "snapshot" exposures - nice 
landscapes and the like - I've taken thus far have been spot on, though 
the meter's limitations must be taken into consideration with backlit 
exposures, just like the M6.

All in all a very nice camera, and for half the price I'd own one 
myself. It was purchased two weeks ago from BH, and has a serial number 
less than 2000.
