Originally posted by Wheatfield Since present lenses are designed for the ~45mm flange distance, there would be no savings in terms of body depth if something like what you are proposing was to use a K-mount.
Solution: very short (pancake) AF catadioptric mirrors. Right.

But could we use Leica LTM glass? Canon FD and Oly Pen-F, sure.
Quote: A new camera line would need to be introduced with lenses designed to work with the new body, which would put Pentax up to three lens systems. This would be acceptable if the present DSLR lens range was complete, but it isn't.
Pentax already has three lines: FA, DA, and 645. A short-register EVIL line (maybe H-mount, after Hoya) would make four. Is Pentoya up to running four separate lens lines? Would a fourth Pentoya lens line be "spreading too thin", or a "wedge into new markets"?? Other than Sigma, Tamron, other multi-mount foundries, how many cam.makers produce more than one line of dSLR lenses? (I'll ignore CCTV and other small-footprint glass.)
Quote: Also, electronic viewfinders need to get better.
Moore's Law will provide for that. What's unreasonable last year will be in WalMart next year.
EDIT: I almost forgot to add my conclusion: Don't expect any FF or APS EVILs from Pentoya, nor Rangefinders. I suspect we'll see such from a maker not already invested in multiple lens lines: Samsung, Fuji, Sony, Panasonic. Hey, it'd be great to have a full range of digicams from one maker: m4:3, APS, FF, 4x4, 645, 6x6, 6x9, etc, and as dSLRs, RFs, EVILs, whatever. Some of these could even be game-breakers. But resources are required, lotsa resources. And unless Pentoya patents and exploits some radical must-have technology, they probably won't have the $$$ and we won't see the goodies. Bother.
