The Giottos M621 Quick Release assembly is equipped with a camera plate that slides forward and back for macro positioning, and features a safety button that limits the amount of sliding on the quick release. The M621 has two bubble levels, and the plate comes supplied with removeable 1/4"-20 and 3/8" camera screws, as well as a spring loaded video pin. Two threaded holes on the side of the quick release allow for storing the unused camera screw directly on the assembly.

Comes supplied with a short (standard) quick release plate; dimensions 3.5 x 2.2 x 0.6". An optional 5.5" long plate is also available.
