With its rounded corners and edges, the P300U for Nikon D300 Body from Markins is designed to custom fit this camera body and feels ergonomically comfortable in your hand. The bi-directional dovetail design can mount vertically or horizontally in any direction into an Arca-type-compatible clamp. The plate is constructed from Duralumin and has a black anodized finish that is scratch-resistant. With a 1/4"-20 threaded camera mount, the camera plate attaches directly to the body, and a 1/4"-20 threaded socket is located on the bottom to attach to a monopod if no clamp is available.
