The Modular Rotation System is the choice working of professionals who shoot sports, weddings, nature or any situation where you need to stay mobile and rapid gear changes are essential. The Modular Component Set V2.0 consists of two individual lens changer pouches, a flash pouch and an accessory pouch that lock to or slide around any Think Tank Photo belt. Since the pouches are modular, the carrying system can be reconfigured to match any assignment, under any condition. FEATURES: A four piece modular component set that fits into a travel bag. 4-Piece modular system designed for a DSLR user with 2-4 lenses Components are padded for extra protection. Components can "Rotate or Lock" on the belt. To rotate, place the white plastic tang behind the belt while attaching the component. Rotating the component prevents the weight of the equipment from creating a pressure point on the hip by being stationary for an extended time. Also, moving the component to a different place on the belt allows a photographer to assume a different position such as kneeling, bracing against a wall, or lying prone without damaging gear. Each Lens Changer has a front stretch pocket for lens caps. Attaches to any Think Tank Photo belt (not included)
