The L-Bracket is precission machined and optimized in design for the Phase One 645 camera. It has laser-engraved marks for the lens axis located on the rear of the plate. The L-Bracket comes with captive-type mounting screws that feature a special, high strength head-to-shank cross section. This plate mounts with a single 3/8”-16 mounting screw.
Your Phase One 645 camera comes with a reducer bushing pre-installed in the camera’s 3/8-inch mounting socket; this bushing must be removed before you can install your new L-plate. Use the supplied (#PH0) Phillips screwdriver to remove the screw that fixes this reducer bushing. With the small screw removed, you can use a small coin to unscrew and remove the bushing. Once removed, align the locator pins then insert and tighten the mounting screw with the supplied hex key. The Phase One L-Bracket is designed intentionally without the use of any cork or rubber-type padding. Direct mating of the camera body and the mounting plate—without any intervening sponginess— improves the mass coupling between the tripod and camera. This assures best vibration damping and enhances rigidity of the system. As an extra benefit you can always mount other type brackets in the extra mounting screw hole on the bracket.
