I tied it to the K1000, i.e., an inexpensive camera. Leica's digitals don't play here, limited functionality and all, because of price. I don't believe people spend several thousand dollars on a Leica just to set focus and aperture themselves. The RD-1 was arguably a commercial failure.
I think such a camera would be a total commerical fiasco. As long as I can turn off, ignore, or use digital options as I choose, I'm happy. I want *more* capability, especially connectivity. E.g., I can't wait to use SD cards with wifi and push files back to a server while I'm out shooting.
Actually your first post was entirely unclear (certainly not in any way explicate) about price being a determining factor which would preclude cameras such as the Leica or Epson digitals from consideration in answering your question - whereas you were explicit about aperture and shutter speed selection and manual focus being your determinants.
In fact, you actually asked a very specific self-contained question, which you even gave a paragraph to itself:
"Would you buy a digital -- SLR or RF -- that allowed you to set aperture and shutter speed and forced you to focus manually? And did nothing else? (Let's assume it produces RAW files, since conversion to JPEG is a frill, right?)"
This does not mention price. If you meant price to be included in the answer to that particular question you would have said "Would you buy a CHEAP digital ..."
If you only meant your question to apply to an exact digital replication of the K1000 (which would then be implicitly cheap because the film K1000 was cheap) then you would not have included rangefinders in the above question as the K1000 was not a rangefinder. :bang:
Then again, you did say a camera "that allowed you to set aperture and shutter speed" rather than "that REQUIRED you to set aperture and shutter speed" so I'm guessing clarity of expression is not your strongest point.
Anyway, now that we have established you meant only CHEAP digital slrs or rangefinders which allow/require you to manually focus and select aperture and shutter speed the question becomes even EASIER to answer:
People have shown there is a huge market for expensive versions of this type of camera (such as the Leica M8 and M9). If people could get something like an M9, but have it be CHEAP as well, there would be a HUUUGE market for it, it would be one of the best selling cameras on the market by far !!!!
