Thank you for viewing. This is a metal macro strobe arm made by KIRK. It's angle adjustable and comes with a clamp. It attaches using the tripod mount of a lens, etc., but there are various ways to use it depending on your ideas. There are no particularly noticeable scratches or stains, and the movement is normal. This is a macro flash bracket designed by KIRK Enterprise Solutions (KES) for lenses with tripod mounts, to be attached to a lens plate. With two joints that allow for stepless directional adjustment, the freedom of flash work is dramatically increased, such as setting the flash above the lens from a high position, lighting from the left or right, or illuminating from behind the subject. The attachment part has a quick-release clamp shape, so if you attach the included plate to the lens plate, attaching and detaching the bracket is one-touch. - Type: Strobe arm - Color: Black - Material: Metal - Adjustment function: Angle adjustable The price takes discounts into consideration, so we cannot accept price negotiations. Thank you for your understanding.
