Getting Started

Mastering Your RTS III

Power the System

Install four fresh AAA batteries into the grip compartment to power the electronic shutter, metering, and integrated motor drive for reliable operation.

Mount the Lens

Mount your Zeiss lens by aligning the red dots and rotating until it clicks securely. Ensure the lens is fully seated to maintain electrical contacts for metering.

Select Exposure Mode

Set the main switch to your desired exposure mode: ‘A’ for aperture-priority automatic or ‘M’ for full manual control over shutter speed and aperture.

Load Film Correctly

Load 35mm film by opening the back, aligning the leader with the take-up spool, and advancing a frame with the motor drive to ensure proper transport.

Engage Vacuum Back

Press the small lever on the film back to activate the vacuum pump, which holds the film flat against the pressure plate for maximum sharpness.

Rewind and Unload

After shooting, use the camera’s motor drive to automatically rewind the film into its canister. Press the recessed rewind button if needed for a mid-roll advance.

Questions About the Contax RTS III System
