Introduced in 1982 by Kyocera/Contax, the Contax RTS II was not just a successor to the earlier Contax RTS camera but, in many ways, a whole new camera in its own right. It featured extremely stringent quality standards in its construction, a long list of new and improved features, and compatibility with the Zeiss line of lenses made for the C/Y Contax/Yashica lens mount.
The RTS II was a revolution of a camera, beginning even with its construction. Kyocera put the components of the camera through strict testing and even redesigned how they assembled cameras in order to have a better manufacturing process. Much attention was paid not just to what the camera could do, but how the camera was made. Kyocera made specific advancements in the film chamber of the camera in order to obtain as flat of film during exposure as possible. The pressure plate was widened and a larger diameter take-up spool was used to reduce film curl. Meanwhile the camera employed quartz-timing in its shutter mechanism to make it even faster and more accurate.
Beyond the design, the camera offered many features targeting the professional market. The camera has only two exposure modes, aperture priority and full manual, but when combined with the aforementioned electromagnetic shutter, this produces a near-instantaneous response. The shutter, while battery powered, could be tripped manually without batteries at a 1/50th of a second. Other features included AE lock (that could be locked in for an infinite amount of time), quartz-timed self-timer, an ISO range from 12 to 3200, and a manual shutter speed range from 1/2,000th to 8 seconds (or 16 seconds when in auto exposure).
Then, of course, were the Zeiss lenses, some of the best 35mm SLR lenses with which one can work. It might be because Kyocera knew they were building a camera behind these particular lenses that they worked so hard to make this camera so good - Zeiss is known for their high standards and they would not want their lenses on just any SLR body.

Contax RTS II with Zeiss 50mm f/1.7
Introduced in 1982, the Contax RTS II was probably a full generation ahead of much of the rest of the camera world. While the "II" designation clues you in that it succeeded the original RTS, it is far more than just a sequel. It is a noteworthy camera in its own right.
Kyocera/Contax overhauled their production lines to build this camera, changing how they approached the assembly of camera bodies. Shifting away from the typical assembly line, Kyocera used a "block system" where components of the camera were built in blocks. These blocks then received their own individual testing, as well as overlapping testing, as they were added on to the camera and tested down the chain by later blocks. The shutters were tested through 2000 repetitions and only perfection passed. Similarly, the camera's CPU received 100 individual computerized tests all on its own. This meant that only the cream of the crop hit the market.
Other than quality, the camera boasted features upon features. An electromagnetic shutter with a super light shutter button made exposure response almost instantaneous - hence the RTS (Real Time System) designation. That electromagnetic shutter could still be fired with a mechanical release, at a single speed, in case of battery failure. More features included: unlimited AE lock, a 97% accurate finder, multiple exposure, quartz-timed self-timer, and a titanium shutter to last you forever.
And of course... the lenses. The Contax system made use of Zeiss lenses built for this mount. It was like owning a 35mm Hasselblad 500C. The lenses rightly get most of the attention - they're amazing - but this remarkable camera deserves the spotlight as well.
