Oh, sorry, my mistake!!!! The Canon Pellix...yes...that was the first production 35mm pellicle mirror SLR, and the thing never took off. Now that you mention the Pellix, I remember some on-line accounts of Pellix users. The Pellix lasted for one year, then was replaced by the Pellix QL, which had the Canon "Quick Load" system,designed to appeal to those were not confident in their ability to load a regular 35mm camera by putting a leader into a slit in a take-up spool. It is hard to appreciate it now, but Canon's 1960's cameras were largely kind of junky. Many of the Pellix bodies broke down well before their time,from what I have heard.
The Pellix had no option for a motor drive nor for a winder.
Like Sony today, Canon was just a mid-line SLR camera maker in 1965, stuck in the pack with Pentax and Minolta and Petri,and that ilk of camera makers. It's hard to over-state how far they have come since the Pellix days. But yes, they did make the "Pellix", which was not very popular, nor successful. I'm not saying this to be hostile toward Canon, but in 1965, Canon as a camera maker was a lot like SONY--trying to take on a market with bigger and better-selling and just "better" competitors with better models. It's not surprising that Canon tried something that was radically new, and different, but which was not really destined to succeed. Heck, I had forgotten about the Pellix...it was kind of like that movie with Afflec and Jolie...basically stillborn. Canon introduced the QL or Quick Load system in 1966...as a way to try and get end-users to believe they could load their fancy 35mm SLR cameras. I think SONY is trying some of the same methods, as a "new maker", to try and stimulate sales.
Nikon had a high-speed 7 frames per second camera at the 1972, Sapporo, Japan Olympics. It was called the Nikon F HighSpeed Sapporo, but it had a mirror that was locked up, and then an accessory finder was used.
Then, in 1974, Nikon produced a limited run of another F variant, The Nikon F HighSpeed Montreal, which went to 9 frames per second. THIS model is the one used later, in 1976, at the Montreal Olympics.
There were also 7 Nikon F Motor Pellicle cameras used at the 1976 Montreal Olympics.
The Nikon F2 HighSpeed Model 1, was introduced at Photkina 1978, and NOT in 1976, which Wikipedia wrongly states.
There was also a Nikon F2 HighSpeed Model II, not mentioned by Wikipedia.
The Complete Nikon System, by Peter Braczko, is where this information came from.
Canon and Nikon's pellicle mirror cameras were all basically technical marvels--but they never really DID ANYTHING great, sales-wise. Sony latching on to the decades-old, failed camera making ideas of the past...where will it lead Sony? One of the things research shows is that the mirrorless camera sales in JAPAN were pretty good last year, but in the USA were not so good. DPreview has a good article on sales of mirrorless cameras, posted a day or two ago. SONY might want to try and sew up the mirrorless market, before Canon's missing mirrorless model hits the streets. SOny bailing on the d-slr market??? I suppose they could. They have consumer electronics and video games to bail themselves out.
