The Giottos MH-658 Quick Release Assembly consists of an Arca-type quick release adapter and a matching camera plate. This system follows the industry-standard Arca Swiss design, and is also compatible with quick release components from other manufacturers (e.g. Arca-Swiss, Foba, Graf/Studioball, Wimberley, etc.).

The sliding camera plate is locked down by turning the side-mounted locking knob. A safety push-button positioned on the side of the adapter adds additional security. A vertical bubble level is incorporated within the locking knob, and a horizontal bubble level is positioned on the base of the adapter. Anti-twist reversible tabs on the plate can be used to prevent slippage when using the head in a vertical position.
