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). Along with the standard bounce and swivel capability, power zoom and a full range of TTL Automatic, Automatic and Manual flash modes, the FL-50R offers the Super FP Mode enabling flash sync at speeds up to 1/4000th second so fill-flash can be used in the brightest of situations. This is achieved by the flash's ability to fire before the shutter opens and stay illuminated until after the shutter closes. Designed specifically for Digital photography, the FL-50R flash also has more even illumination with less corner fall-off than traditional film flashes.
Four remote control Communication Channels can be set by the User to avoid interference with other peripherals in the vicinity. Photographers also have the Option to control wireless transmission distance by choosing between three signal strengths for a range of up to 33 feet.
