"This is a ProMediaGear Universal quick release DSLR and lens plate. It was specifically designed for the cameras that do not have custom mounting plates such as (Olympus, Sony, Pentax, Canon, Nikon, Leica, Panasonic etc. and even video gear.) Their quick release plate offers exceptional fit and security. By using only a slightly protruding hard rubber cord for anti-rotation, they ensure that the plate rests directly on the camera eliminating any play or ""mushiness"". It features strap loops that are built-in to the plate. It also provides safety stop screws which prevent the camera from sliding out in either direction. 100% made, designed and assembled in the USA Three (3) 1/4-20 mounting holes for direct mounting to tripods, mono-pads, etc. Safety stops (ensure the plate doesn't slip out when clamp is loosened accidentally) Machined aircraft quality aluminum construction Hard black anodized surface coating and wear resistant finish Application The plate will fit virtually all SLR camera bodies and will mount to all ProMediaGear, Really Right Stuff, Arca-Swiss, Markins, Kirk, Jobu Design or any other standard Arca Swiss clamps."
