I don't see a long term future for Leica in camera bodies. Digital has commoditized camera bodies in the same way "quartz movements" commoditized wrist watches. There is no such thing as a "fine quartz movement" as there was a "fine Swiss movement" in the mechanical era. The $10 cheapo quartz watches keeps the same time as a $1500 luxury brand. There is a difference in this analogy, however. Watches are more of a jewelry item than cameras, and the higher prices are not for improved functionality as in the "Swiss movement" era. Now you're paying for what is essentially an expensive man bracelet than improved performance via a better mechanically engineerd precision movement.
My entry level Nikon? My $60 Quantaray 24mm that doubles as a APS-C 35? The $200 Nikon 35mm f1.8? All together I have less than $800 tied up in a kit that I defy you to tell me any real difference in output with an M8.
Digital has done to cameras what quartz movements have done to watches.
Except one problem for the luxury camera maker. Cameras aren't jewelry. (I'll refrain from a snarky comment...)
In the long run, Leica would be better served, IMO, being just a "luxury" lens manufacturer and make lenses in other mounts like Nikon and Canon. Sigma/Tamron have done nicely filling focal length gaps in the line-up for the big boys. Leica could be the luxury Tamron and give up bodies all together.
That's what I'd do if I was Leica CEO.
I'd do just what they are doing.
For decades Leica relied on hint the "pro" system, which required "pro" or "master printer" labs and facilities. not just a status symbol, Leica's got their cachet because they were real workhorses of photojournalism.
Big stumble when AF and microprocessors entered the realm, but still the Yuppies liked their bourgeoise cameras. And they still had access to professional finishing.
Huge stumble when analog stares into extinction by digital much faster than Leica or Kodak project (Fuji, Canon, Nikon, and barely, Pentax and Olympus, get it right). Suddenly you're $800 DSLR is starting to come close to the $6,000 Leica, because those Yuppies are only ever making 4x6's and the photojournalism market is starting to shred.
Leica suddenly looked very vulnerable to being a living antique.
But....by putting the processing in the camera and then the home computer, Leica has been able to move far beyond the home darkroom or "pro" photo lab clique.
Anyone with a home PC can now enjoy Leica's mystique, much of it well-earned, although the IQ part now a diminishing asset compared to the luxury brand association.
Digital has broadened the market enormously for Leica, just like suburban driveways made it possible to overspend on SUV's. Leica can afford to put far too many resources into quality of production compared to IQ value...and they still sell because of the conspicuous consumption desire.
No longer tied to film and the endgame of processing, Leica's market has exploded. M-mount is everywhere. If people want Leica lenses, so what? Make bodies, too. It's all about the brand.
As for film, none of the major camera manufacturers support film camera production anymore. They benefited enormously at the expense of film as now all those $'s going into processing are now going straight to more Leica glass and Monochrom bodies. Kodak and film users lose, Leica gains.
