Press release

New RC1 Olympus & Panasonic TTL Receiver for DS Strobes

Now true Olympus or Panasonic LUMIX TTL strobe exposure is available via fiber optic connection with a Ikelite DS strobe!

With the RC1 TTL Receiver and a compatible camera with RC flash mode, actual exposure data is calibrated and communicated directly by the camera. This is far more accurate and consistent than “slave TTL” modes built into some underwater strobes which watch the camera’s built-in flash and react.

An individual RC1 TTL Receiver and compatible fiber optic cord is needed for each strobe. Use of two strobes requires two receivers. See strobe and cable compatibility information below.

This product attaches to an Ikelite DS strobe. It is not intended to be attached to a housing and will provide no functionality if attached to a housing bulkhead. This receiver is not compatible with non-Ikelite strobes or non-digital Ikelite strobes.

RC Mode TTL Strobe Exposure

The receiver makes DS Strobes compatible with the Olympus and Panasonic LUMIX RC flash mode, providing automatic TTL exposure. For accurate performance set the DS strobe to “TTL” and the camera’s flash mode to “RC”. Using the camera’s flash exposure compensation controls to make fine tuned adjustments to the strobe’s intensity.

Manual Strobe Exposure

The strobe’s output may be adjusted using the manual power settings built into the strobe (varies by model). Make sure the camera’s flash mode is set to manual. Choose the minimum flash output necessary in the camera to trigger the DS strobe. This will conserve the camera’s battery power.
