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 downsized1 to fit the α E-mount cameras, this compact flash is as powerful as guide number 452. Recycle time is approx. 2.5 seconds3, with flash output up to approx. 210 times3.
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 groups4. You’ll appreciate wireless convenience and varied lighting for flashes placed at distances of up to 30m5.

Reliable and precise control in any setting
Radio signals enable stable connection over a wider shooting area (about 30 m / 98.4 ft.). 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.
