Of course there's also the mechanical issue of sensor positioning & alignment to overcome...

This wasn't an issue with film so surely it would be possible for the sensor to 'autoalign' ?

One reason that this concept never took off in the past was the interface.  There wasn't really an easy way to retrofit the digital controls necessary to a film camera to set ISO, WB, etc etc.

Take your Spotmatic, screw off the back (the flap that opens to allow access for loading film) at the hinges, screw on the digital back with all the buttons, etc. and voila! one Spotmatic-D.

It was an issue with film, just not a very big one.  Most 35mm film provided the resolution equivalent of about a 6-8mp FF sensor, give or take (& depending on the film of course), so it was pretty tolerant to slight discrepancies in film flatness.  Contax's RTS III (& some Contax MF systems) had a vacuum system that would suck the film against the backplate so that it was absolutely flat, and folks were able to get a bit more resolution out of higher-end film as a result.

A modern high-MP CMOS sensor needs to be *absolutely* aligned and positioned in the plane of focus, so closely that it pushes the limits of the production techniques used to make our mass-produced camera bodies.  This is part of the reason why we have AF calibration in our cameras now, so that we can compensate for manufacturing tolerance variance in the distance between the lens mount & the sensor plane.

It's a great idea (Leica did this with the Digital-Modul-R); the only issue is that you'd have to make an awful lot of different models to work with all the different manufacturers' camera systems out there...

As with any big project, you start with one ... and obviously exclude Canon EOS, Minolta Alpha, and Nikon at first. Furthermore, the basic framework for the digital "back" remains the same no matter what (35mm) camera.

Plus, with most cameras you can replace the film rewind lever with another dial for functions.

Hmmm seems like they had the exact same idea as I did. Who was first? :P

It does not matter to me.  As long as such product exist, I am buying!

Well maybe some one or some corporation is listening ;)

A flexible sensor is very interesting ... they should start with B&W, as it would be easier (just one layer).

They already make flexible displays, so it should be possible (but the degree of bending needed to get it on a roll is something else....).

Nice design idea, pity about the April 1st disclaimer though  :'(
