The 30” Moon Unit™ is a unique octabox-like accessory that is designed specifically for the AlienBees™ Ringflash unit or retired Zeus™ ZRM1 Ringflash head with its own quick-release rotating speedring. Unlike conventional octaboxes, the camera lens can "see" through the center of the Moon Unit™, thereby achieving a unique large-source light on the camera axis. Using the Ringflash with the Moon Unit™ produces subtle, controlled, almost indiscernible shadows and large appealing catchlights at modest camera-to-subject distances. Its minuscule depth and weight allow handholding right along with your camera.
