External Flash with Wireless Radio Control
Powerful yet compact
Radio wireless flash control for versatile shooting
Supply powerful lighting with the compact high-performance HVL-F45RM clip-on flash. Explore freedom of built-in wireless radio control in multi-flash settings and conventional optical wireless communication. Easy operation, excellent reliability, expert results — especially for enthusiasts of compact α E-mount interchangeable-lens cameras.
Powerful compact with stamina
Dramatically downsized to fit the α E-mount cameras, this compact flash is as powerful as guide number 45. Recycle time is approx. 2.5 seconds, with flash output up to approx. 210 times.
Multi-flash shooting via built-in radio wireless
With its built-in wireless radio-controlled system, the versatile HVL-F45RM can be used as either commander or receiver, supporting a wide range of shooting situations. As a commander, connect up to 15 units of compatible flashes or receivers in up to 5 groups. You'll appreciate wireless convenience and varied lighting for flashes placed at distances of up to 98.4 feet.
Reliable and precise control in any setting
Radio signals enable stable connection over a wider shooting area (about 98.4 ft/30 m). Compatible off-camera flash units or receivers pick up radio signals — in bright light, around obstacles, and even when installed behind the camera. That means more consistent results without pairing errors.
Operability & reliability for expert shooting
Intuitive operation via camera-like menus
Enjoy quick intuitive operation with tab menus just like that on the camera.

One press of the 'Fn' button calls up the Quick Navi screen, letting you directly change shooting settings.
