The FL-50R is an external flash unit that allows wireless* flash settings to be controlled from the camera body. Wireless flash transmission channel settings enable selection of flash/no flash for groups of multiple flash units. In addition it allows TTL auto, auto, and manual modes to be set; offers a bounce and swivel head; and flash coverage is automatically adjusted in several steps to correspond to the image area when zooming. The FL-50 provides GN28 at a 12mm focal length (equivalent to 24mm on a 35mm camera; ISO 100) and GN50 at 42mm focal length (equivalent to 85mm on a 35mm camera; ISO 100).

(* The E3 is the only camera compatible with the Olympus Wireless RC Flash System as of October 2007. The traditional clip-on flash system is usable with any camera model.)
