The dynamic range of the M9 mono and other technical details are not that interesting to every Leica buyer. The 'fondlers' as the are called will stick it in a safe place and occasionally stroke it on birthdays and at christmas.
I don't know if this is going to be a limited production camera or not, but Leica have been bold, but I wonder if it will ever be repeated. I can imagine the M10 would have as good ISO performance or better, if Nikon / Canon and so on can do it why not Leica? Okay - we know they can't / won't, but it should be significantly better than the M9.
I think Leica obviously want to at least try to tempt die hard B&W M6/7 users to move to digital, not just to kill film off, but because they can make a few Euros at the same time (if we have Euros by the time it ships). I moved away from film because the film I love isn't made. Saying you'd rather buy a half ton of tri-x is fine for some - I loved it, but not all the time!
The quality of mono images from Aperture 3 and LR 4 is a big improvement over the early days, so surely this will move on and make even the most ardent film lover think digital. Maybe there's denial, as much as film has had a slight come back, it will not be around forever?
I'm looking forward to some more samples and real world use, I gather there will be more revealed tomorrow on the Leica site. Anyway, I'm very interested in one as I could use a Voigtlander 15mm with no colour shift. Think of the savings!
