The Sunwayfoto MCP-01 Mini-Clamp Package comprises a pair of DDC-26 clamps and the hardware necessary to join them either lined up with each other or oriented at a 90° angle from each other. The two clamps join securely bottom to bottom, which gives you an Arca-style clamp on the top and on the bottom of the assembly.
With such a construction, you can position the dual clamp precisely along a dovetail-style camera rail (from Sunwayfoto or other from manufacturers). Because the DDC-26 clamps can be parallel or perpendicular to each other, an attached camera (outfitted with an Arca-style camera plate, of course) can either smoothly slide fort & aft or left & right along the rail, creating the ultimate nodal slide for precision projects such panoramic photography.
The Sunwayfoto DDC-26 Mini Screw-Knob Clamp is an all-metal, Arca-swiss style clamp that attaches to tripod heads via its 1/4″-20 mounting hole and included 5mm screw. Its jaw opens with a range of 38-41.5mm and its captive-design knob locks tightly to secure your camera. Designed with a “+” shaped mounting groove on the bottom, its orientation can be changed to fit quick release plates set in either direction and it can be perpendicularly attached to a second DDC-26 and used on a rail mount. Two safety relief grooves help to keep your camera secure.
