Small, powerful, reliable radio wireless flash

This high-output GN28 flash offers the type of optimized performance and control that only a genuine Sony product can provide. It can be controlled directly from the camera and is small enough to fit in a pocket while offering professional durability as well as wireless radio communication for a wide range of applications.

Made by Sony for stunning images

The HVL-F28RM offers exceptional performance and stability with α7 series. It offers versatile features and detailed control plus the solid reliability needed for professional and advanced amateur applications in a compact, portable unit.

An ideal GN28 flash for compact mirrorless cameras

The flash head and internal layout of the HVL-F28RM have been redesigned for reduced size and greater portability, making it a perfect match for compact mirrorless cameras. Although it slips easily into a pocket, the HVL-F28RM delivers output that rivals the high-end HVL-F45RM at the same illumination angle and can be effectively used for bounce lighting in a wide range of shooting situations.

Metal shoe foot with rugged side frame

The Multi Interface Shoe features a newly developed metal shoe foot with rugged side frame, significantly increasing strength and reliability.

Dust- and moisture-resistant design

Like Sony's high-end flash units, the HVL-F28RM features a dust and moisture design that can withstand the rigors of professional work, even in challenging outdoor environments.

Effective overheating prevention

An optimized flash-control algorithm provides excellent flash performance while effectively preventing overheating, for long-term stability and reliability.

Comprehensive control from the camera

Flash compensation, light ratio, and other detailed flash parameters can be controlled directly from a compatible camera.
A camera custom key can be assigned to call up the flash parameter display so that adjustments can be made while looking through the viewfinder and gripping the camera. Flash parameters are shown in the selected camera display language.

Direct output adjustment for quick operation

Dedicated light output level buttons (LEVEL -/+ buttons) directly control light output and flash compensation for fast, efficient operation. The light output of other wirelessly paired flash units can also be adjusted in this way for a smooth, stress-free workflow.

Comprehensive flash features

The HVL-F28RM also includes the same high-speed sync, multi-flash, and other flash features as the HVL-45RM and HVL-60RM.

Radio wireless operation for versatile shooting

The HVL-F28RM features stable radio wireless communication. One HVL-F28RM that will function as a commander can be mounted on a compatible camera and paired with a second off-camera HVL-F28RM unit that will function as a receiver. Radio communication provides reliable communication over longer distances than are possible with optical communication, even in bright sunlight or when there are obstacles between the camera and subject. When used as a flash commander the HVL-F28RM can control up to 15 flash and/or receiver units in five groups at distances of up to 114 ft/35 m for extraordinary lighting control versatility.

Reliable off-camera control in any setting

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.

Auto white balance adjustment

Color temperature information is transferred from the flash unit to the camera to ensure accurate white balance for natural-looking colors. With compatible cameras flash output is automatically balanced with ambient light conditions so that skin tones are rendered with ideal white balance.

Flash control based on face detection

The HVL-F28RM works with the face-detection capabilities of compatible cameras to balance flash output with ambient light conditions so that the subject's face is rendered with lifelike, accurate white balance.

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.

Multi/Micro USB terminal

The flash unit can be connected to a computer via its Multi/Micro USB terminal for convenient software updating.

Through-the-lens (TTL) wireless flash

Flash output can be accurately determined by through-the-lens light measurement, even when shooting wirelessly. The position and direction of the flash can be adjusted to soften shadows and highlights when shooting a subject from the front, or to add shadows for a sense of depth when needed. Wireless flash-ratio control is available.

The Multi Interface Shoe features a newly developed metal shoe foot with rugged side frame, significantly increasing strength and reliability.
