Ikelite RC1 Olympus & Panasonic TTL Receiver for Underwater DS Strobes

Ikelite RC1 Olympus & Panasonic TTL Receiver for DS Strobes

Enjoy true Olympus and Panasonic LUMIX TTL strobe exposure via fibre optic connection with your compatible Ikelite DS strobe. The RC1 TTL Receiver works seamlessly with cameras in RC flash mode, enabling accurate TTL exposure by communicating directly with the camera—far more precise than traditional “slave TTL” systems.

A separate RC1 TTL Receiver and compatible fibre optic cord are required for each strobe. Using two strobes requires two receivers. This product connects directly to an Ikelite DS strobe and is not designed for use on housings or non-Ikelite strobes.

For AOI housings, please refer to the RC1 Olympus TTL Receiver for AOI LED Flash Trigger and DS Strobes instead.

RC Mode TTL Strobe Exposure

Compatible with Olympus and Panasonic LUMIX RC flash mode, this receiver provides automatic TTL exposure. Set your DS strobe to “TTL” and the camera to “RC” mode for accurate performance. Adjust flash intensity using your camera’s flash exposure compensation controls.

Manual Strobe Exposure

Manual strobe output can be controlled via your strobe's built-in power settings (varies by model). Set the camera’s flash mode to manual and use the lowest flash output necessary to trigger the strobe—conserving your camera’s battery life.
