Camera OverviewContax RTS

The Contax RTS is a 35mm film SLR camera built around a full-frame 35mm sensor format, meaning image resolution is entirely dependent on the film stock you choose to load. It accepts lenses via the Contax/Yashica mount, giving shooters access to a wide range of compatible glass. The body is constructed with a metal chassis and a titanium top cover, and comes in at 142 x 89.5 x 50 mm with a weight of 700g — solid and substantial in the hand without being unwieldy.

Focusing is entirely manual, with no autofocus system of any kind, which keeps the shooting experience deliberate and tactile. The viewfinder is an optical pentaprism SLR design, offering a direct optical view through the lens. ISO sensitivity spans from 12 to 3200, accommodating both slow fine-grain emulsions and faster stocks for low-light work.

Flash connectivity is handled via a direct X contact hot shoe with anti-shock provision, plus a PC sync socket, with X-sync at 1/60 sec. Power comes from a 6V silver oxide or alkaline battery using common formats such as the Eveready 544 or Mallory PX28. There is no image stabilization, no weather sealing, and no electronic connectivity of any kind — this is a purely optical, mechanical-and-electronic film camera built for deliberate, hands-on photography.

DescriptionContax RTS

The Contax RTS is a 35mm film SLR built on a full-frame 35mm format, with image resolution determined entirely by your choice of film stock. The body is constructed with a metal chassis and titanium top cover, measuring 142 x 89.5 x 50 mm and weighing 700g — a solid, confidence-inspiring build that feels purposeful in the hand. Lens mounting uses the Contax/Yashica mount standard, connecting the body to that system's range of optics.

Composing and focusing is done through an optical pentaprism SLR viewfinder, with all focus adjustments handled manually. Film sensitivity is set across a range of ISO 12 to 3200, giving you flexibility across a broad spectrum of emulsions. For flash work, the camera provides a direct X contact hot shoe with anti-shock provision and a PC sync socket, both operating at an X-sync speed of 1/60 sec.

Power is supplied by a 6V silver oxide or alkaline battery — compatible formats include the Eveready 544, Mallory PX28, and alkaline Eveready 537. There is no weather sealing and no image stabilization system of any kind.
