Our 4 Way Macro Shot Fine Focus DSLR Camera Rail provides a platform for your camera when attached to a tripod or copy stand. In situations such as close-up work or long distance photography this allows you to adjust the camera position slightly, left or right, or forward or backwards, without moving your tripod or other support. The rails are geared, providing smooth precise adjustment, and have locks once you achieve the right position. This allows you to adjust up to 2 inches left and 2 inches right of center. Also allows you to adjust the camera base forward up to 4 inches. Features all metal construction, a female 1/4x20 thread on the bottom for attaching to a tripod, and a 1/4x20 male thread for attaching your camera.
