Compatible with Canon E-TTL, the MF-R76C TTL Macro Ring Flash from Godox illuminates your subject with a soft and even light, which is ideal for macro shooting scenes. 2. The ring light consists of two components: a controller that slips into your camera hot shoe, and the ring flash, which mounts on your lens. 3. Godox includes 49, 52, 55, 58, 62, 67, 72, and 77mm adapter rings to ensure wide compatibility with most lenses. With a guide number of 45.9 ft at ISO 100, the MF-R76C provides detailed, wrap-around lighting for your close-ups. The twin-tube design also allows users to set each side to different power ratios, enabling higher contrast lighting when desired. 4. Adding to the unit versatility, the MF-R76C offers TTL and manual modes combined with HSS, first, and second curtain sync capabilities. Besides that, two focus-assist lamps with 10 adjustable levels of power ratio are useful for low light scenes. 5. The control unit powers the system via an included rechargeable lithium battery to ensure long-lasting shoots, giving you up to full-power 550 flashes.
