Ideal for macro photography to make precise positioning movements to achieve the perfect framed shot, for QTVR and other precise copy/repro work, this plate has finger-tip control for ultra-fine positioning - but with a simple lock-release lever for fast set-up. Two plates can be interlocked at 90° for full lateral/forward/back movement (over 4.7"). In extruded aluminium, the plate has 1/4" and 3/8" holes and screws for tripod and camera mounting.
