In 1990 the RTS II was replaced by the Contax RTS III.
While RTS II retained the appearance of its predecessor, many regard this as a totally different camera. Many important changes were made. Some of this camera's key features and improvements over the RTS include:
- Quartz Timing
- 97% viewfinder (as opposed to the 92% viewfinder of the RTS)
- Horizontal titanium-foil shutter curtain
Naturally, RTS II was an extension of the original RTS philosophy, which was to create a camera and lens system that was focussed on optical excellence, and flexibility. While generally 'conservative' in terms of design, Contax has been known for interesting (and sometimes unusual) feature innovations. In particular, RTS and RTS II have an AE-Lock feature, that allows the photographer to lock the exposure (EV value) for an unlimited time, unlike many other camera manufactures from the era, which retain a short "EV memory" feature. As well, The body has a manual shutter release system, should the meter battery die. This facility allows the shutter to be actuated mechanically at 1/50 s.
A noteworthy point is that this camera can easily suffer from poor cold-weather metering performance if an alkaline battery is used. Silver Oxide batteries are recommended, and indeed Contax produced a variety of external power packs for this and other RTS cameras that allow the batteries to be carried in a warm pocket in case of cold weather.
