Compatible with DSLR cameras with a hot shoe, the ML-150 II Macro Ring Flash from Godox illuminates your subject with soft, nearly shadowless light that reveals every detail. The ring light consists of two components: a controller, which slips into your camera's hot shoe, and the ring flash, which mounts on your lens. Godox includes 49, 52, 55, 58, 62, 67, 72, and 77mm adapter rings to insure wide compatibility. The control unit is the brain and power pack of the system. The manual unit can regulate light intensity in 11 steps and recycles in 0.1 to 2 seconds and runs on four AA batteries that give you 300 to 1000 flashes.
