Originally posted by GibbyTheMole So, after seeing Ricoh's GXR with it's interchangable lens/sensor units, the thought occurs: Why wouldn't it be possible to make a DSLR along the same lines, but instead of marrying the sensor unit to the lens, make an interchangeable sensor/lens mount unit? Unlike using adapters as an afterthought, such a setup would allow the registration distance to be correct for the whatever mount it was for, and everything could be made to work right to begin with. I would think the ability to use a variety of lens mounts on one camera would make it a big seller.
Of course, licensing the mount design from Nikon, Canon, etc. might be a sticking point.
Might be a dumb idea, dunno...

It might be seen as an admission that the GXR concept was flawed to begin with. It is my understanding that Ricoh claims that having a specific lens mated to a specific sensor allows them to fine tune them to work together more effectively than having interchangeable lenses.
If you have interchangeable lenses, do you really need an interchangeable sensor? Would anyone buy the integrated modules?
Someone has suggested, in another thread, that Ricoh has announced a sensor module that will accept Leica lenses, so maybe I'm wrong.
Making the physical mount interchangeable would be easy. It would be sort of like a reverse t-mount, a simple matter of machining. I think that the real problem would be in the electrical connections. Not only do the physical locations of the connections differ between the various lens mount systems, but having the firmware in the camera to handle all the different protocols would be a programming challenge.
Then too, if you have a camera that accepts, say, Canon, Nikon and Pentax (of course, since its our forum) lenses, users of those lenses would want it to accept p-ttl, i-ttl and e-ttl flashes. Again, this is a serious firmware issue. Interchangeable hotshoes?
Not really a dumb idea, and probably do-able, but I suspect it would be prohibitively expensive.
