Cognisys Quick Release Clamp
The Cognisys Quick Release Clamp was designed to fit on the StackShot Arca Adapter plate to securely hold your camera to the StackShot Macro Rail. The clamp is Arca Swiss compatible and it will also mount directly to our rotary tables using one of the rotary table spacer kits. This clamp can be mounted in both perpendicular and parallel directions on the macro rail (see below for examples).
The Quick Release Clamp features all aluminum and Stainless Steel construction, all aluminum parts are black anodized. The knob is a large 1" knurled knob for easy grip and secure tightening. The knob is captive to prevent loss of any parts in the field.

Quick Release Clamp Orientation
The Quick Release Clamp can be mounted to the Arca Adapter Plate either perpendicular to or parallel to the camera. This allows mounting of the camera to the StackShot Rail either by the lens foot (left image a Wimberley P-20) or by the camera (right image a Wimberley P-5 plate). The bolts to attach the clamp can be removed directly from the top - no need to remove the Arca Adapter Plate from the StackShot Rail.
