This dramatically downsized1 compact, lightweight clip-on flash with guide number (GN) 45 is best suited to use with the A7 series. The flash supplies powerful output even for bounce lighting, recycling only takes approx. 2.5 seconds, and stamina in performance delivers up to approx. 210 bursts.
Built-in wireless radio control:
Use this flash with a compatible camera4, for multi-flash shooting, even under strong sunlight or from relatively distant locations thanks to its radio-controlled system. HVL-F45RM can be either wireless commander or receiver. As a commander, HVL-F45RM supports up to 15 units of compatible flashes or receivers in up to 5 groups, for connecting with remote units at up to 30 metres6. It also works with optical wireless communications.
Bounce head for flexible lighting:
HVL-F45RM bounce head for flexible lighting rotates 360 degrees horizontally (180 degrees in both left and right directions) and also tilts 150 degrees upwards and 8 degrees downwards, providing the illumination you want depending on shooting situations.
Sony's Quick Navi control interface provides easy, intuitive access to lighting parameters via one easy press of the 'Fn' button. Everything you need to know is right there on the screen and accessible using a few buttons and the control wheel, thereby minimizing the necessary operations required to adjust settings before you shoot.
Customizable key assignment:
Key customization function allows easy assignment of frequently used features for quick operation. Customizable settings include lighting compensation level and flash output level. Customizable keys are highlighted in red.
You'll enjoy effortless operation of flash features. Tab-structure menus on the LCD screen are the same as those on the camera body for fast access and intuitive use.
Cool running and energy efficient, the LED light enables you to create natural lighting and shadows for both movies and stills.
High-speed sync (HSS):
Take advantage of synced flash with high-speed shutter. Whereas conventional sync shooting requires that the shutter speed be the same or slower than the synced flash speed, the aperture would be narrowed, making it difficult to get background bokeh effects. But with high-speed sync (HSS) you can use flash with any shutter speed, even up to the highest shutter speed provided by the camera. This allows you to increase the aperture as needed to create a narrow depth of field that keeps your subject in perfect focus while the background blurs, for beautiful portraits. Wireless high-speed sync is also possible with compatible cameras.
Dust and moisture-resistant design:
Count on reliable flash even in challenging outdoor conditions with specially designed seals at joints around the durable body to keep out dust and moisture. This is a particular bonus in outdoor usage where you have no control over various factors including wind and environmental dust.
Through-the-Lens (TTL) wireless flash:
Even when performing wireless flash shooting, flash output can be determined based on accurate measurement of the amount of light through the lens. Since you can freely change the position and direction of the flash unit exactly as you want, it's possible to soften intense shadows and suppress blown highlights when shooting a subject from right in front (of the subject), or add soft shadows that emphasize a sense of depth and presence. Wireless flash ratio control is available.
Advanced Distance Integration (ADI):
ADI provides automatic metering that is virtually unaffected by the reflectance of subjects or backgrounds, maintaining correct exposure even with overly reflective or overly dark subjects. It pre-flashes the unit to incorporate the reflected light measurement, together with precise distance information from a compatible camera's lens, to achieve the optimum flash level.
Test flash mode:
The test flash mode enables you to check shadows on the subject before taking photos, and also to check the light level using an external flash meter, which is essential for studio photography. The light level of the test flash depends on the light level setting in manual flash (M) mode, and the flash unit fires with a light level of 1/1 in through-the-lens (TTL) mode.
Auto zoom control optimized for image sensor size:
This flash unit automatically selects the appropriate flash coverage for the focal length of the lens on the attached camera within the range from 24 mm to 105 mm. This function also adjusts the flash zoom to match the camera's image sensor size, minimizing light fall-off at the image periphery. The flash coverage required for cameras using 35 mm full-frame and APS-C size image sensors differs substantially, and this intelligent function automatically provides the optimum flash coverage for each.
Auto White Balance Adjustment:
Colour temperature varies according to the environment you're shooting in, and the colour temperature of a flash should match that of the ambient light to look natural. With this intelligent function, colour temperature information is transferred from the flash unit to the camera for correct white balance setting, to help you capture more natural-looking colour reproduction in flash photography.
Multi/Micro USB port:
This flash features Multi/Micro USB port for supporting software update to the latest version via connected PC.

Great speedlight for a7rii!I purchased this flash specifically for my a7rii for on-the-go applications when I don't want to carry my bigger light. I'm happy that the flash pattern is nice and round and light is soft which surprised me in a good way of course. I used to own other Nikon flashes before I switched to mirrorless (happy I did) but this one from and for Sony is just awesome! The features like installed radio, which is super easy to pair with FA-WRC1M, focus assisting LED/video light and off course the perfect size for a7rii are worthy of investment!

Amazing for Low Light SituationsHave been using it almost non stop for low light shoots and it greatly improves the autofocus and isolated capabilities of my 7rii!!!
