30-Inch Moon Unit by Paul C. Buff: The 30-inch Moon Unit is a unique softbox-like device that attaches to the AlienBees (ABR800) ringflash unit with a quick-release rotating speedring. The camera’s lens can see through the center of the Moon Unit to achieve 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 catch lights at modest camera-to-subject distances. Its minuscule depth and weight allow handholding right along with your camera, or you can use it as a conventional off-camera compact softbox. The Moon Unit is lightweight, compact and easy to assemble. It consists of a reversible gold/silver reflector surface in an octagonal shape, a removable front nylon diffuser (with a center hole), a removable black fabric mask to convert the octagonal shape to a circle, a rotating speedring, assembly rods and a special reflector that bounces the flash energy into the Moon Unit (instead of forward). The suggested retail price is $59.95.
