Manfrotto 3419 Micrometric Positioning Sliding Plate Focusing Rail, great cond.

Description

The
Manfrotto 3419 Micrometric Positioning Sliding Plate
is a quick release system that allows for some positioning within the clamp for fore-aft macro adjustments.
It is the ideal tool to make precise positioning movements to achieve the perfect framed shot, for macro photography, for QTVR, and other precise copy/repro work. This plate has finger-tip control for ultra-fine positioning, but has 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"). Made of extruded aluminium, the plate has 1/4"-20 and 3/8" holes and screws for tripod and camera mounting.
Works great, rarely used. I'm not doing much macro work, so passing this along.
Also selling lights, soft boxes, other macro rails, and other photography related items. Please see my other listings. Can combine shipping.
