Sony HVL-F45RM 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 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.

  • Radio-control connection with various types of off-camera units
  • Wireless control of up to 15 units in up to 5 groups

[1] HVL-F45RM (receiver / off-camera flash)
[2] FA-WRR1 (receiver) + compatible flash (off-camera flash)
[3] FA-WRR1 (receiver) + studio flash (via sync cable)
[4] HVL-F45RM (commander / on-camera flash)
[5] FA-WRC1M (commander)

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.

  • Reach deep into the composition
  • Reliable also in bright light
  • Leap over subjects and obstacles

Bought this for use with Sony A58 camera and it fits straight on. Good size and weight for camera and so far resukts have been great. No intention to use off-camera or as part of lighting system at the moment but good to know it has the capability. Compatible with newer camera such as Sony A7 I have eyes on. Relatively new to photogaphy the unit appears simple to set up and use.

Followed the steps provided in manual. But was not able to trigger optically. While my old M320 triggers optically.
Awaiting technical resolution.
