The KES geared-track focusing rail saves you time and improves results when shooting precise macro work. This well-balanced focusing rail moves back and forth smoothly at your command. It's ideal to use with stacked lenses for super macro shots.
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.
