Hmm.. perhaps there's a market for an updated crop sensor digital rangefinder, but to be be honest, see nothing revolutionary in it. Nothing to show any sign of progress since the R-D1 or M8 were introduced. A reasonably priced full frame digital CL/ CLE-type camera would be a game changer. For those of us who shoot film Leica's (and I'm suggesting this is where the untapped niche is for a more affordable digital rangefinder), we want our lenses to give the same field of view on a digital rangefinder as our film one.
Those folks who were both willing to accept a crop factor and also the myriad of risks that came with buying a used digital rangefinder, have already settled for an M8 or R-D1. What I'm talking about here are all those shooting Leica or Bessa film rangefinders, these folks remain entirely unserved by both Leicas current offerings, as well as used Leica or Epson options.
The naysayers who say this can't be done (and for a reasonable price), seem to be many, and as naysayers go, all sound reasonable, but when is the last time the voice of moderation or reason was the fuel for advancement. To say there is no market for a more reasonably priced full frame digital rangefinder is ridiculous. I'm not sure how many film rangefinder shooters are out there, perhaps Leica M & Bessa production numbers would give us a good idea, but it easily numbers in the tens, if not hundreds of thousands, and to say that is not a market is simply ridiculous.
Something like that, could be the making of Leica, but to be honest they don't seem to have that much vision. I think they could do quite well with a digital CL/CLE serving as an entry level body, and a full M as their flagship. Less people might buy M9's, but that would be more than made up for by combined sales CL/CLE's & M's, as well as the fact Leica would now own an enlarged digital rangefinder market effectively, and put Leica on quite a stable footing simply through camera volume sales.
