Introduction One thing I like about Canon is their wider scope of business vision even for pre-visualizing and m realizing how a fruitful product from successful technological research into commercial application. Perhaps the success of the divergence from FD to EOS partly changed the culture of the Company in attempting to try out new innovations and observe how the market perceive. For those of you who missed the confusing state from the mad rush of sophisticated camera automation in camera design during early '80 which actually resulted in decrease of sale in SLR cameras caused by confusion on average consumers. Mistakes have learnt, so, the evolution of autofocus SLRs in a way also has come to a junction similar to what has happened back then. With streams of models of fully equipped AF single-lens reflex cameras appearing between the end of '80 and early '90, advanced functions such as multi-zone metering, evaluative metering, high-speed film winding, and moving object predictive AF are being adopted as standard functions. It is a fact that these latest technologies are still greatly contributing to expanding the range photographic expression. However, inherent disadvantages of a single-lens reflex camera still remain to be solved. So, it takes a giant dare to allocate some budget to try out to see if this can create a new plateau, both on business as well as technological ground. If succeed, you will have a trending setting technologies for others to follow, worst scenario, you have something unique in your system where others don't.
Virtually time lag-less photography many be a different experience for action sport photographers. The EOS SLRs have been widely used in all major international sport meets/events from Formula One, World Motor GP, Olympic, Football, Basketball, Motor Cross, Olympics etc..The intense atmosphere and speed of F-1 car is well demonstrated with this photo by James North, from UK.

In relating to major weakness in 35mm SLR design (something that one of those Leica user will use to tell you for hours..), two long pending main issues still await to be resolved: 1). Momentarily blinding of visible image during instant of exposure. Although a single-lens reflex camera definitely features the ability to take pictures identical to the scene viewed in the viewfinder, it also blinds the photographer at the very instant of shutter release; 2) There is a release time lag during exposure. Both may not be significant to many users, but actually, they leads to other secondary issues. During the early seventies, Canon and Nikon have experimenting a few limited experimental cameras with a fixed (non-moving) Pellicle (may use word, "pericle") Mirrored SLR cameras for specific usage in unleashing potential for rapid sequence shootings. Although the main reason was to enhance the rapid burst in accordance to the special motor drive made for such purpose but the other advantages of Pellicle Mirror brought have already being identified. The next decade, the application of fixed mirror SLR camera remained as special production unit that aimed to resolve demand for such needs rather than seriously exploring its potential commercially on a large scale basis.
Relative: Some references on the use of Perricle Mirror in SLRs - The consumer-class Canon Pellix QL models; 9.0 fps Canon F-1N High Speed Motor Drive Camera for 1972 Lake Placid Winter Olympic Games; the 1, 5, 10, 14.0 fps Canon New F-1N High Speed Motor Drive for 1984 L.A. Olympic Games. Other labels: Early version of the 3.5, 5, 7.0 fps Nikon F High Speed Motor Drive camera (example: TRIBUNE Nikon F High Speed); a subsequent updated version of 9.0 fps Nikon F High Speed Motor Drive camera for 1976 Montreal Winter Games; 10 fps Nikon F2 High Speed Motor Drive camera for 1978 as well as a Nikon F2 HS MD for 1984's LA Olympic Games; more recently, Nikon poor answer to Canon's EOS-1n RS was a 13 fps Nikon F3 High Speed ("F3 HS") Motor Drive camera of 1996. Poor - because it was still a Manual Focus camera.
What do all these tell ? As you taker notice of various showcased models above, all of them were designed as special application camera and limited to small quantities only. But on the other hand. Canon has made good use of their two decades of experience in mastering Pericle Mirror usage in SLR manufacturing. The only difference between Canon and Nikon in the usage on Pellicle mirror technology now is, Canon took the initiative in deploying it in their trade they know best. So, the first mass market SLR camera with a truly functional Pellicle Mirror in placed of conventional reflex mirror was the 1989's Canon EOS RT - this was the first time Pellicle Mirror used in an autofocus SLR camera. "RT" is short for Real Time - a very appropriate term to use as it has solved the above-mentioned fundamental disadvantages.
A limited production quantity of 20,000 units of the Canon EOS RT have been all sold within the Company's prediction of positive responses from consumers. The extremely encouraging demands have laid the foundation for the development of an EOS-1 equivalent of a high grade RT camera to strengthen Canon new footing at the professional user's market further as the entire reversal of market leadership in this highly competitive segment took Canon more than two decades to realize it. On top of that, various advantages of a fixed mirror would extend technological boundaries of conventional SLR camera design and many new photographic possibilities emerge from adoption of it in the professional orientated Canon EOS-1N.
Originally, I think Canon was also scratching their heads in adopting a common term for this new breed of a SLR camera type. Some trade names was suggested, like EOS-1n HS -RS, EOS-1n HS Pericle etc.. In a Q & A session with some Canon Engineers, this question was well addressed by the representatives " Why is "RS" used instead of "RT"? Is RS mode different than RT mode?" The "RT" in the EOS RT name stands for "Real Time", indicating the camera's full-time viewfinder image and short release time lag of just 0.008 sec. (5 frames/sec.; max. continuous exposure speed). The EOS-1N RS features an even shorter release time lag (0.006 sec.) and achieves a fast continuous shooting speed of approx. 10 frames sec., achieving Real-time Super-high-speed (drive) continuous shooting operation, thus the "RS" name. The mode name has also been changed accordingly to RS mode....". Another informal interpretation of a lesser taste for RS can also be Rapid Shooting or any other definition that can make you feel comfortable..
Well, the basic development concepts of the Canon EOS-1n RS was aimed to provide a top-grade AF single-lens reflex camera which is capable of taking pictures at the real-time/decisive moment with professional expectation in performance and reliability. The main difference for this camera is the RT technologies used in relation to Canon electronic mount system and other related add on usage of pericle mirror such as integrating the high-speed motor drive function, the camera is capable of making high-speed continuous exposures at a rate of approx.10 frames per second and fully equipped with all the basic functions and performance of the simultaneously developed Canon EOS-1N.
Canon EOS-1n RS AF Film-based SLR camera
On a realistic note, I would think Canon could has realized this readily available special application camera may not be contributing too much of corporate revenue but being a core model of the EOS-1N series, which includes a full lineup of other models from EOS-1N, EOS-1N HS and EOS-1N DP, the inclusion of EOS-1n RS as a member of the EOS-1 series serves a business purpose like showcasing Canon superior technological leads over competitions as well as increasing brand awareness and market presence of Canon cameras in the professional camera market.
