Ideal for macro photography to make precise positioning movements to achieve the perfect framed shot, for QTVR and other precise copy/ repro work, the new sliding plate has finger-tip control for hairs-breadth positioning but with a simple lock-release lever for fast set-up. Two plates can be interlocked at 90 degrees for full lateral/forward/back movement (over 120mm). In extruded aluminum, the plate has 1/4-in. and 3/8-in. holes and screws for tripod and camera mounting.
