Made of durable and lightweight aluminum, the rail is designed for macro photography. The millimeter markers on the entire length allow the camera to be precisely moved along the rail. The markers are also on the quick-release mounting bracket, so that moving the camera relative to the object is possible on two axes. The screw on the back of the quick-release handle allows you to “lock” it in place, ensuring your camera stays in a fixed position.

A screw mechanism ensures the plate slides smoothly on the rail. Mounting the plate on the handle is adjustable a lever that presses the plate to ensure structural stability. The GMR-150 rail can be connected to all heads, nodal rails, and handles that use the Arca-Swiss mounting standard.

Fastening the rail is also possible on other accessories that have a 1/4″ male thread, as the GMR-150 has two 1/4″ female threads.
The set includes a macro photographic rail and two Allen keys.
