With dual gearing and the integrated Q=Base Arca-Swiss type quick release system, the Novoflex Castel-Q Focusing Rack is an invaluable tool for any macro photographer. 5.5" of total movement is available, and the entire assembly can be attached to either a conventional tripod head or an Arca-Swiss compatible quick release clamp (made by Arca-Swiss, Foba, NPC, Gitzo & others).
The Novoflex Q=Plate series QPL-1 square quick release plate fits any Arca-type quick release system (except the Arca Swiss Flip-Lock). It features a 1/4"-20 camera screw, on a 1.65" square plate that can slip in from any direction.
The bottom edges are dovetailed for smoother loading and unloading from the clamp, as well as less abrasions. The screws of the Novoflex plates work with both traditional flathead screwdrivers as well as 5/32" Allen wrenches.
Note! The Novoflex Arca-type quick release plates are thinner by the slimmest of margins than Arca-Swiss quick release plates. They are not recommended for use in the Arca-Swiss Flip-Lock quick release clamp.
