The Surefoot Clamp Plate allows you to have the functionality of both an arca-swiss type of plate and quick-release built in.
Also call a Nodal Rail, or Perpendicular Plate, there are several uses for this device.
1. Attach it under your camera body (with an arca-swiss body plate or L Bracket) to produce a useful macro slider.
2. Use it in your gimbal head (with a body plate or L bracket on the camera) to allow non-collared lenses to fit and balance properly.
3. Create a panoramic or VR setup. Ideally used with a BWG-HD3, it is very easy to setup the correct nodal point for X, Y, Z axis
