Sunwayfoto MFR-150S Overview

The Macro Focusing Rail with Screw-Knob Clamp from Sunwayfoto gives you the ability to accurately adjust your camera's fore-or-aft position when shooting macro photography. The clamp at the top is Arca-type compatible and is secured with a screw-knob. The focusing rail itself has a double-dovetail mount and is compatible with most Arca-type clamps available.

The Macro Focusing rail has both a ratchet handle, for fast and quick adjustments, and a thumb-screw knob along with engraved index marks on the side of the rail for fine adjustments. The CNC machined T6061 aluminium rail holds a maximum weight capacity of 15.4 lb, but may hold less weight once the angle of the rail is changed.

The Type III black anodized aluminium is scuff and scratch resistant and the finish is also resistant against corrosion. In addition, two focusing rails can be stacked for dual axis adjustments (fore-or-aft and lateral). Located on the bottom of the plate are two safety stop screws to prevent any accidental pulling or falling out of the rail when a clamp is partially open.
