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 downsized2 to fit the α E-mount cameras, this compact flash is as powerful as guide number 453. Recycle time is approx. 2.5 seconds4, with flash output up to approx. 210 times4.

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 groups5. You’ll appreciate wireless convenience and varied lighting for flashes placed at distances of up to 30m6.

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..

Intuitive operation via camera-like menus

Enjoy quick intuitive operation with tab menus just like that on the camera.

Quick Navi control interface

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

Flexibly assignable custom function

Assign often-used functions to up, down, left, right, centre keys and control wheel (highlighted in red) for easy access.

Rotate head horizontally 360°

Flexible head rotates 180° left and 180° right for rapid bounce operation.

Tilt 150° upward and 8° downward

Use easy 150° up / 8° down tilt adjustment, plus one-touch rearward bounce.

Support vertical shooting

Bounce flash is possible, even with the camera held in vertical composition.

Common features for uncommon lighting techniques

Control shutter speed and flash intensity for the precise effect you want.

Wireless multi-flash ratio control

Set intensity for each of up to three groups of wirelessly controlled flashes.

High-speed sync (HSS)

Flash can be synchronised to all shutter speeds — unlike conventional daylight sync, in which shutter speed must be equal to or slower than flash speed.

Advanced Distance Integration (ADI)

By acquiring accurate distance information between the lens and subject through TTL metering, ADI delivers precise flash intensity control that is not influenced by high or low reflectance of the subject or background.
