Item Description:
GN.58 High-Intensity Flash, High-Speed Sequential Shooting, Compact and Lightweight, Dust and Splashproof Design, Advanced Wireless Controls, 100 LUX LED Video Light/Focus Assist Lamp, 24-200mm Angle of Coverage, 14-20mm With the Built-In Wide Panel

The high-intensity FL-900R boasts a guide number of 58 meters (at ISO 100) and covers a wide range of focal lengths with an electronic zoom head. A built-in wide panel enables you to use wider focal length lenses and have perfect coverage, and a catchlight panel illuminates your portrait subjects' eyes effortlessly.

The FL-900R boasts dust and splashproof construction that perfectly complements weatherproof OM-D camera bodies and all M.Zuiko PRO lenses, enabling you to illuminate your subject in the harshest of weather. Dark and stormy conditions are no match for your complete OM-D system.

With Olympus' RC (remote control) system, you have access to a variety of wireless flash options. Use the FL-900R as a master flash to trigger additional RC compatible flash units, as a slave in one of four independently controlled groups, or as a commander flash using the included IR filter. Four available channels mean the RC Mode is resistant to interference from other photographers, so you can comfortably shoot events when other photographers are nearby.

The built-in 1.5w LED light in the FL-900R is a useful tool as both a continuous source for video shooting and as a focus assist light when shooting stills. One-touch on/off control lets you quickly access 100 Lux power (at 1m) when you find yourself in a low-light situation.

When paired with the OM-D E-M1 Mark II camera body, the FL-900R becomes a sequential shooting powerhouse. The flash fires continuously at 10 frames per second for 100 shots at 1/128 power or 30 times at 1/32 power! State-of-the-art charging circuitry enables the FL-900R to recycle in just 2.5 seconds when shooting sequentially, so you're assured of getting the shot. An improved FP mode with expanded range lets you shoot beyond E-M1 Mark II's sync speed without the worry of overexposure. The new Multi Mode allows you to capture movement in your photos, by firing the flash multiple times during one exposure, further enhancing your creative control.
