External Flash with Wireless Radio Control
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.
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.
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.
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.
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 35 m/114 ft for extraordinary lighting control versatility.
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.
