I find the Topcon R a fascinating SLR and I only ever seen one, in 1976.
Sorry, I disagree. Something can be a first, without being either famous, or important. But please carry on, it's an interesting conversation and I have no wish to impede it...
VP Exakta First slr for the proletariat. Hasselblad 1000F Olympus Pen F 16mm Narciss Pentax 110 Polaroid SX-70 Duflex First 35mm SLR Asahiflex and several of it's siblings Super D Graflex Kodak/Nikon DCS 100 first generally available digital slr
The VP Exakta was rather expensive compared to the K.W. Reflex Box, which came out the same year.
There had also been a few even simpler roll film SLRs before that, like the Ensign Reflex: http://camera-wiki.org/wiki/Ensign_Roll_Film_Reflex
Or the exceedingly primitive Ihagee Roll Paff Reflex: http://www.pacificrimcamera.com/pp/iharollpaff.htm
- the Canon Pellix (pellicle mirror)
Nice to see this on your list. I've never used one but it seems like a really nice idea, the advantages of an SLR with none of the disadvantages. If you happen to know more about the Pellix it would be interesting to know why the concept failed in the marketplace (mirror too delicate, too dim etc.).
...
The benefits cited were no mirror shake, ...

Of course, i've handled one Pellix, as i'm a Canon fan...
The problem with the pellix was: The pellicle robs speed AND, worse, it affects picture quality. I have a review by "Modern Photography" and they say the speed loss is measured at 2/3 of the stop. The loss of sharpness was rated at one "subjective quality" grade. That is, what was rated as "very good" was rated as "good" with the Pellix compared to the FT using the same 50/1.8 lens.
The other problem is that any dirt or smudges on the pellicle mirror will have an effect on image quality.
And yet, due to the mirror, the viewfinder image is dimmer, since we're not capturing the full light output of the lens.
The benefits cited were no mirror shake, but even by the time the Pellix was launched, the Canons had very very low mirror shock; even the Canonflex RM (which is earlier) has very low mirror shock (they use a geared mechanism to deaccelerate the mirror - little known fact). Same for the FT, FTb and F-1 cameras. Even the A-series cameras have very low vibration levels.
and the Pellix design allowed for lenses with protruding rear elements that would clash with a moving mirror. Canon offered one 35mm lens specifically for the Pellix, but never many any other use of the advantage.
Nikon built a "Pellix" variant of the F2 as a high speed motor driven camera. Eliminating the time for mirror lift and then mirror return allowed for higher framing rates.
As the owner of an EOS RT I wouldn't mind an EOS-1N RS myself, simply because of that scintillatingly high 10fps motor drive but it's not a priority for me. If I come across one at the right price, perhaps. But, although I don't pretend to know a lot about this category of cameras, I'm not sure it really was the fastest fps rate for a film SLR? The fastest mass produced or readily available one, perhaps. If you have a look at the following links there are a couple of cameras referenced (the Nikon F3 High Speed & 1984 Canon F-1 High Speed) at 13.5 fps and 14fps, respectively. It's a subject Stephen seems to know more than a bit about, so he may be a good person to ask for more details?I believe Canon later introduced a couple Pellicle Mirror SLRs, one was the Eos RT, the other the EOS 1N RS. The 1N RS still holds the film SLR continuous burst rate record, thanks to not having to flop the mirror around all the time. 10 Frames per second!
Thanks for the interesting reply, I would have imagined that it was also quieter than other SLRs but maybe not...
Olympus OM-1, opened the smaller, lighter segment, soon by be followed by smaller, lighter from all the camera manufacturers.
