Long Rail Plate
The ultimate combination: a 6-1/2 inch dual-dovetailed plate with an Arca-style quick release platform. Firmly supports macro lenses virtually to ground level for those low angle shots. Easily rotates the quick release platform 90 degrees to grip the camera body plate and slide the long plate through the ball head's quick release platform to function much like a focusing rail. Also great for panoramic photography.
