novel, potential new SLR: any mount becomes interchangeable for any lens.

Of course the 35mm Hasselblad-stye cameras from Rollei.
And Contarex and Adox models.

All are SLR's except for the Adox.

Umm, kind-of: Kickstarted by a British order, it took longer to perfect it to the iconic Mustang IV / P-51D variant after Rolls Royce suggested dropping a Merlin in.

Not a bad idea. In my view the instant return mirror is the most over-rated of all camera gizzmos. My old Exakta VX iia had no instant return mirror, and once I was used to the idea I didn't see that as any great disadvantage. Kiev 60 also has no instant return mirror.

No doubt the RR Merlin and the P51D version was excellent. However, my statement is still true: from plans on paper to first flying aircraft was approximately five months.

I know that comparing experienced engineers in a wartime situation with inexperienced photo neophytes isn't exactly fair, but still: five months is amazing.



If a non-instant return mirror is good enough for a 500C/M (a camera that Jesus himself used [*]), it's good enough for me!

You know, sometimes a simpler technology is better in terms of less bugs to attempt to iron out. Like you, I agree with this statement.

Back in 1966 when I was 16, I got my first 'real' camera, a Minolta Autocord CDS, primarily because I was told that composing on such a screen would be easier and better. When I got my first 35mm SLR, a Canon AE-1, in 1978, I learned rapidly that this was not the case.

We are told over and over again, that lack of an instant return mirror hampers our ability to make great pictures because what we do not see afterward, becomes a perilous omission. It does not. There are many truisms in photography that are primarily marketing ploys with little or no sense. - David Lyga

Would just like to see Nikon come out with an updated version of the N75 N80.

First if Nikon ever introduce another film camera it would be more like the FM3a or even a rangefinder that makes use of the new Z mount. However, that's unlikely. Now what do you mean by updated N75/N80? What kind of features should be on it?
 
The Zeiss Ikon Contarex and Contaflex 35mm SLR cameras came with interchangeable backs that could be changed in mid-roll. Work pretty well but they are a bit complex so if you are not using them regularly you need to carry the instructions with you. A couple of my Contarex backs leak light when I remove them from the camera so I don't use them when I intend to change things out. I think the Contaflex backs were a bit more successful and mine at least seem to work a little better.

However, as with many cameras, the fly in the ointment is that all these cameras are getting old and will likely require some service. Not easy to find someone who can service them, at least in a timely fashion, any longer.

Both cameras do have a wonderful selection of lenses though and I think they are worth working with for that reason alone.
