The Sony HVL-F28RM external flash with wireless radio control for Alpha 7 series cameras offers the performance and optimized control options that only Sony can provide. It can be controlled directly from the camera and is small enough to fit in your pocket, as well as offering professional-grade durability and wireless radio communication options for a wide range of applications. The flash head and internal layout have been revised to reduce size and increase portability-it is the perfect match for a compact mirrorless camera. Although small, the device offers power to rival the high-end HVL-F45RM flash and efficient performance with bounce light in a variety of shooting situations.
