10" Lead Screw Focusing Macro Rail with Quick Release Clamp

The Hejnar Photo 10-Inch Single Stage Macro Rail is a professional-grade linear motion instrument designed for high-precision macro photography and lab alignment tasks. Built with a robust 5/8-inch thick base, this lead screw rail provides the mechanical rigidity needed to minimize micro-vibrations. Its dual-speed positioning system allows for rapid framing and microscopic focal plane adjustments, and it functions exceptionally well as a nodal slide for parallax-free panoramic photography.

Quick Overview & Key Features

• Dual-Action Positioning: Press the slider release lever for fast coarse adjustments, then engage the lead screw for sub-millimeter fine control.
• Secure Locking Mechanism: Features a side lock to firmly secure the slider in place after achieving the perfect focus point.
• Modular Quick Release Clamp: Top slider clamp can be oriented in three distinct positions for maximum equipment compatibility (note: cannot be set with the knob on the same side as the slider lock knob).
• Universal Arca-Swiss Base: Integrated bottom dovetail fits industry-standard quick release clamps from RRS, Kirk, and Wimberley.
• Nodal Slide Functionality: Optimized design allows it to serve as a precise nodal slide for professional panoramic stitching.

Detailed Product Description

The Hejnar Photo 10-Inch Single Stage Macro Rail is engineered for photographers who demand absolute precision. By adjusting the distance between the camera and subject via the lead screw rather than the lens focus ring, you maintain a constant magnification ratio—a critical requirement for successful focus stacking.

Reliability is at the core of this design. The 5/8" thick aluminum base provides superior torsional stiffness, ensuring that heavy professional camera setups weighing up to 15 lbs remain rock-solid. The lead screw delivers exactly 1.06mm of travel per turn, providing the fine sensitivity needed for high-magnification macro work.

This rail is as versatile as it is precise. Beyond its primary role as a focusing stage, its 10-inch length makes it an ideal nodal slide for panoramic photography, helping minimize parallax errors by finding the lens's nodal point. Each unit is proudly CNC-machined in the USA and finished with a black hard-coat anodize for maximum wear resistance.
