High-power GN45 flash with built-in wireless radio control

Shoot masterfully illuminated photos thanks to the flash unit’s guide number (GN) 45 regardless of its compact body and wireless radio control system. Since the flash is also equipped with an LED light for stills and movies, you can make the most of the camera’s still and video capabilities. Dust- and moisture-resistant design lets you use the flash outdoors without worry.

High-power compact flash

This dramatically downsized compact lightweight clip-on flash with guide number (GN) 45 is best suited to use with the α7 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 camera, for multi-flash shooting, even under strong sunlight or from relatively distant location 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 meters. It also works with optical wireless communications.

Bounce head for flexible lighting

HVL-F45RM bounce head for flexible lighting rotates 360° horizontally (180° in both left and right directions) and also tilts 150° upward and 8° downward, providing the illumination you want depending on shooting situations.

Quick Navi

Sony’s Quick Navi control interface provides easy, intuitive access to lighting parameters via one easy press of “Fn” button. Everything you need to know is right there on the screen and accessible using a few buttons and control wheel, thereby minimising the necessary operations required to adjust settings before you shoot.

Customisable key assignment

Key customisation function allows easy assignment of frequently used features for quick operation. Customisable settings include lighting compensation level and flash output level. Customisable keys are highlighted in red.

Tab-structure menus

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.

LED light

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 required 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 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 emphasise 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 optimised 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 24mm to 105mm. This function also adjusts the flash zoom to match the camera’s image sensor size, minimising light fall-off at the image periphery. The flash coverage required for cameras using 35mm 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.
