GN28 flash
ideal for compact hybrid devices

The HVL-F28RM's flash head and internal configuration have been redesigned for reduced size and increased portability. Even though it fits in a pocket, the HVL-F28RM provides output similar to that of the high-end HVL-F45RM, at the same illumination angle.

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

Complete controls from the camera
Flash compensation, light ratio & other detailed flash parameters can be controlled directly from a compatible device. A custom camera key can be assigned to invoke the flash setting screen. Flash settings are displayed in the selected display language of the camera.

Premium functionality and control in a portable unit

Direct light adjustment
Dedicated buttons directly control light output and flash compensation. The light output of other wireless associated flash units can also be adjusted this way for a smooth, trouble-free workflow.

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

Wireless radio operation for versatile shooting

The HVL-F28RM features stable wireless radio communication. An HVL-F28RM that will function as a remote control can be mounted on a compatible camera
and associated with a second external HVL-F28RM unit which will function as a receiver. Radio communication provides reliable communication over longer distances than optical communication, even in direct sunlight or when there are obstacles between the camera and the subject. When used as a flash remote control, the HVL-F28RM can control up to 15 flashes and / or receivers in 5 groups at distances of up to 35m for extraordinary lighting control versatility.
