Product Description:
Linear motion lead screw focusing or macro rail. The bottom rail (5/8" thick) includes dovetail that works with clamps while the slider is equipped with quick release type clamp. The clamp can be oriented in 3 positions; it cannot be set with the knob on the same side as the slider lock knob. Camera to subject distance can be adjusted in fine increments. Fast positioning can be done by pressing slider release lever and sliding the slider on top of the rail. After setting position, slider can be locked in position with the side lock. Lead screw delivers 1.06 mm of travel per full revolution. Works very nicely as a nodal slide.
