The MFR4-5 Macro Focusing Rail from Oben is a lightweight macro stage designed for precise 4-way camera alignment. Its ability to make small incremental adjustments is ideal for close-up work, tilt-shift or macro-photography. The MFR4-5 provides 2.75" of maximum front to back movement and 1.25" of maximum left to right movement controlled by dual-level adjustment knobs. The two angles of movement are controlled by independent top and bottom rails which may be separated using the included Allen key. This allows the top rail to be used alone as a front-to-back macro rail. The rail is also equipped with an integrated Arca-type compatible quick release clamp and an included Arca-type plate. The plate uses a 1/4"-20 screw mount compatible with most cameras. The rail can also be mounted on most tripods by utilizing the built-in 1/4"-20 and 3/8"-16 tripod mounting threads. A durable aluminum construction provides smooth operation for extended use and keeps the unit lightweight at only 1.3 lb.
