In 1973 the Contax name was licensed to the Japanese maker Yashica to create a prestigious brand of 35mmcameras and interchangeable lenses in cooperation with the German company. By that time, Yashica was a production giant with considerable electronic camera experience, and was seeking ways to expand sales and improve brand name recognition in the highly competitive 35mm SLR market. Thus began ‘Top Secret Project 130’, a collaboration with Carl Zeiss to produce a new, professional 35mm SLR with an electronically-controlled shutter, bearing the Contax brand name, along with a new line of premium quality lenses. The F. Alexander Porsche Group was hired to complete an ergonomic and styling study of the new camera. The result was the all-new Contax RTS, which appeared at Photokina in 1974, and proved an immediate hit.

The RTS featured an electronically-controlled, horizontal cloth focal plane shutter with speeds of 1 - 1/2000 sec. plus B, interchangeable focus screens, and the ability to accept a number of professional accessories including power winders, professional motor drives, and both infrared and radio-controlled remote releases.

Carl Zeiss Tessar 45mm f2.8 lens:

Exceptional sharpness in the classic Tessar 4-element design. It has an extremely small size and is light weight. Slightly wider than "Standard" lenses for application in all types of photography.

'Im in love with this lens.

It's very sharp and contrasty and has a focal length that is appropriate for a wide variety of situations.

The lens particularly impresses me with its sharpness at all apertures. I got this lens with a Contax Aria and they make a first-rate combination for travel. This little 45mm Tessar has produced so many "keepers" for me that I feel like it is becoming indispensable. I have bigger zooms that cover the 45mm range, but the color rendition, contrast and sharpness of the Contax 45mm Tessar seem to be the most satisfying.
