AT A GLANCE
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-F28RMA offers exceptional performance and stability with the 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*1 flash for compact mirrorless cameras
The flash head and internal layout of the HVL-F28RMA 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-F28RMA 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.

High reliability and durability in a compact flash unit
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 *2
Like Sony’s high-end flash units, the HVL-F28RMA features a dust and moisture design5 that can withstand the rigours of professional work, even in challenging outdoor environments.
*2 Not guaranteed to be 100% dust and moisture proof.
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.
High-end features and control in a portable unit
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-F28RMA 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-F28RMA features stable radio wireless communication. One HVL-F28RMA that will function as a commander can be mounted on a compatible camera and paired with a second off-camera HVL-F28RMA 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-F28RMA can control up to 15 flash and/or receiver units in 5 groups *3*4 at distances of up to 114 ft/35 m for extraordinary lighting control versatility.
*3 Up to 5 groups in GROUP mode, or 3 groups in TTL/Manual mode. 3 Group max. when used as a receiver.
*4 When used as a receiver, the HVL-F28RM can only be assigned to three groups: A, B, and C. It cannot be assigned to group D or E.
*5 Sony test conditions.
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.
