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 fingertip control for hairsbreadth 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 aluminium, the plate has 1/4′ and 3/8′ holes and screws for tripod and camera mounting.
