2.4 GHz Wireless Radio TTL System. You can use the Olympus FL-700WR Electronic Flash as a 2.4 GHz radio commander or remote as part of Olympus’s radio wireless system, alongside the FR-WR Receiver and FC-WR Commander. The system operates at a range of up 98.4 feet and doesn’t require line of sight. The FL-700WR also supports the Olympus TTL system for automatic exposure, high-speed sync, and special camera functions like High Res Shot and Focus Stacking.

Flash Output. The FL-700WR features a 12-75mm zoom range, 7mm wide panel, and flash output of GN:137.8’ @ ISO 100/75mm.

Multiple Flash Modes. The FL-700WR offers flash modes that make exposing your subject even easier than before. You get Super FP flash sync, first curtain, second curtain, and slow-sync modes, and you can wirelessly switch among these modes.

Functionality. The FL-700WR Flash can be adjusted from 0° to 90° tilt for bounce and will swivel in a 360° radius (180° both left and right). There’s also a continuous LED light for video purposes. The unit is powered by four AA batteries (not included).

High-Quality Build. This flash is IPX-1-rated, dust- and splash-resistant, rated for use in temperatures between 14° and 104° F, and weather sealed in the same manner as Olympus’s high-end cameras, so you can use it in a range of inclement conditions.

Compatibility. As of January 2019, the Olympus Wireless Radio System is only supported by the Olympus OM-D E-M1X / E-M1 Mark II / E-M1 / E-M5 Mark II and PEN-F.
