This is very encouraging for leica enthusiasts in a way. While it would be great to have everything, it bears out the notion that the lens is still the crucial part of a set-up. Where can I pick up a DMR?

There's an interesting thread on fredmiranda.com that discusses the tradeoffs between sensor color accuracy and low-noise high-ISO performance:

there's a lot to wade through but it seems that better color accuracy comes to a large degree from sharp frequency cut-off in the sensor's color filter array (CFA) which limits bleeding of one wavelength into a photosite intended for another wavelength; a sensor with a weaker CFA requires less amplification so high-ISO noise is less.

If this is true it would help explain the DMR's poorer high-ISO noise performance along with its excellent no-fuss colors.
