Ben Z said:From what I'm led to understand, the proximity of the exit pupil of non-retrofocus rangefinder wide-angle lenses w.r.t. the image plane creates a major problem with digital because the pixels are inside little wells and the well walls block light rays coming in at a steep angle. That's why there have to be microlenses over the sensor to channel the light rays into those wells. That technology was pioneered on the Epson, but there is still some serious vignetting. The M8 although it has significantly less of a crop factor, has less vignetting (try a C/V 15 on both cameras and this will become immediately apparent). So microlens technology improved, but apparently not enough yet for decent performance on a 24x36mm sensor. If that hurdle is jumped then I expect Leica will implement a FF sensor. I'm sure if/when they can get the results people expect without needing IR filters on lenses they'll do that too (although that will pose quite a logistical headache for people using an M8 as a second body, unless M9 has anti-cyan-drift correction also). However I believe Leica will do these things because they will be exciting and beneficial to their loyalist customers, not because they feel compelled to keep up with the state of the art. They managed to keep the R line going well past the time autofocus was accepted and even embraced by the mainstream of professional photographers. Despite much vocal dissidence on the 'net, most guys in Leica's bread-and-butter market imbue every Leica-branded product with qualities that put it out front of any others.
I agree and I think it will be a while before we see a FF digital M. In the meanwhile I'll be taking pictures with my (very very) lovely M8.
