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. Quick release plates are fitted into a compatible tripod's pan head or ball head quick release mechanism for easy removal and replacement of equipment.
The M621 has two bubble levels, and the plate comes supplied with removable 1/4"-20 and 3/8"-16 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.
