NiSi Quick Adjustment Macro Focusing Rail NM-200S with 360 Degree Rotating Clamp

The NiSi Quick Adjustment Macro Focusing Rail NM-200S is a precision instrument designed to give you complete control over camera positioning in macro photography. Whether you’re working with extension tubes, close-up lenses, or dedicated macro optics, this rail lets you dial in focus with confidence.

At the heart of the system is an 18cm adjustment range delivered via a smooth collapsible thumb-screw knob with engraved index marks on both sides of the 20cm rail. The stage travels 1mm per revolution, giving you the fine control macro work demands. The integrated Arca-type quick-release clamp features a convenient push button for swift large adjustments and rotates a full 360 degrees, so you can reposition your camera without removing the plate from the clamp.

The NM-200S arrives with a longer quick-release plate designed to support telephoto lenses safely, complete with a groove for camera straps. Four detachable foot nails let you use the rail directly on a tabletop for hands-free setup, while the 3/8″ and 1/4″ screw holes on the base accept any standard tripod head. The rail mounts into most Arca-type clamps and ball heads on the market.

Built from CNC-machined aluminium with a hard-anodised, corrosion-resistant finish, the NM-200S resists scuffs and scratches through years of use. It safely handles loads up to 5kg. For even finer control across two axes, two rails can be stacked together.
