Comprehensive Product Description

The 10-Inch Lead Screw Micro Focusing Rail is an indispensable tool for macro, product, and scientific photography where depth of field is razor-thin. By moving the camera sensor rather than adjusting the lens focus ring, this rail maintains a constant reproduction ratio, allowing you to systematically capture perfect image slices for focus stacking software.

This rail features a dual-drive system designed for efficient field use. For rough framing, simply press the quick-release stage button to slide the camera freely along the 6.3-inch travel path. Once close to your subject, release the button to engage the high-precision lead screw mechanism. Turning the control knob allows you to dial in your focal plane with microscopic control. Each incremental mark on the adjustment scale translates to an ultra-fine 0.1mm of travel, while a complete 360-degree rotation advances the camera exactly 1.06mm.

Mounting and rig integration are completely seamless. The base rail slides directly into any standard Arca-Swiss compatible tripod head clamp. On top, the slider stage is equipped with a premium quick-release clamp that can be repositioned in four different orientations. This modular flexibility allows you to run your camera setup parallel or perpendicular to the rail footprint. Engineered to manage hefty professional setups, its rigid construction safely holds heavy telephoto and macro lens configurations up to 15 lbs horizontally, and up to 10 lbs in a vertical orientation for down-angle studio work.
