    Stable radio wireless communication


    The HVL-F28RM features stable radio wireless communication. One HVL-F28RM that will function as a commander can be mounted on a compatible camera[FN|Refer to support information for supported cameras and functional compatibility.] and paired with other off-camera HVL-F28RM units that will function as a receiver. Radio communication provides reliable communication over longer distances that are possible with optical communication, even in bright sunlight or when there are obstacles between the camera and subject. Slow sync, rear-curtain sync, and multi flash are supported[FN|Refer to support information for supported cameras and functional compatibility.].

    Comprehensive control from the camera


    Flash compensation, light ratio, and other detailed flash parameters can be controlled directly from a compatible camera[FN|Refer to support information for supported cameras and functional compatibility.], and a custom key assignment can allow adjustments to be made while looking through the viewfinder. Flash parameters are shown in the selected camera display language.

    Lighting tailored to individual scenes


    With powerful output that rivals the HVL-F45RM, plenty of light is available for bounce applications, and the flash angle can be set as required via 0, 20, 40, 60, 80, and 120 degree click stops. A lock is provided at the 0-degree position to prevent unwanted angle changes in hectic shooting situations.

    Direct light level control


    Dedicated + and – LEVEL buttons allow direct, speedy light output and flash compensation control, and can also be used to control the same parameters on other wirelessly paired flash units for smooth, efficient workflow.

    High-speed sync (HSS)[FN|Refer to support information for supported cameras and functional compatibility.]


    Normal maximum flash sync speeds mean that the shutter speed must be stopped down when using daylight fill flash, making it difficult to produce background bokeh. High-speed sync allows the flash to be synchronised to the full range of shutter speeds[FN|Refer to support information for supported cameras and functional compatibility.] so that large apertures can be used to create bokeh wherever desired.

    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.

    Multi/Micro USB terminal


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

    Multi/Micro USB terminal


    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.

    Flash control based on face detection


    The HVL-F28RM works with the face detection capabilities of compatible cameras[FN|Refer to support information for supported cameras and functional compatibility.] to balance flash output with ambient light conditions so that subject's face is rendered with lifelike, accurate white balance.
