Driven by a world-class \u003cstrong\u003eMitutoyo micrometer head\u003c\/strong\u003e, this linear stage enables ultra-fine camera-to-subject distance control with a generous 50mm range. Built with an Arca-Swiss compatible bottom dovetail and a highly adaptable quick-release slider clamp, it offers the uncompromising stability required for professional studio and demanding technical workflows.\n\u003c\/p\u003e \n\u003chr\u003e \n\n\u003c!-- ===================== QUICK OVERVIEW \u0026 KEY FEATURES ===================== --\u003e \n\u003ch2\u003eQuick Overview \u0026amp; Key Features\u003c\/h2\u003e \n\u003cul\u003e \n    \u003cli\u003e\n\u003cstrong\u003eExtended Micrometer Range:\u003c\/strong\u003e Features a genuine Mitutoyo micrometer head providing a 0–50mm travel range with precise, readable 0.01mm graduation increments.\u003c\/li\u003e \n    \u003cli\u003e\n\u003cstrong\u003eFully Rotatable Barrel Assembly:\u003c\/strong\u003e The micrometer head can be turned and oriented in any direction to fit your physical workflow, with the default scale facing upward.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003e4-Position Indexable Clamp:\u003c\/strong\u003e Slider block is equipped with a quick-release clamp that can be unbolted and locked in four distinct orientations using a central locking screw and anti-twist dowel pins.\u003c\/li\u003e \n    \u003cli\u003e\n\u003cstrong\u003eUniversal Arca Dovetail Base:\u003c\/strong\u003e The bottom rail features an Arca-Swiss compatible dovetail profile for seamless, wiggle-free integration with standard clamps, gimbals, and ball heads.\u003c\/li\u003e \n    \u003cli\u003e\n\u003cstrong\u003eVertical Weight Capacity:\u003c\/strong\u003e Built to handle demanding vertical configurations, rigidly supporting loads up to 4kg (approx. 8.8 lbs) perpendicular to the ground.\u003c\/li\u003e \n    \u003cli\u003e\n\u003cstrong\u003eHorizontal Weight Capacity:\u003c\/strong\u003e Confidently holds up to 15 lbs (parallel to the ground) under full camera and lens weight.\u003c\/li\u003e \n    \u003cli\u003e\n\u003cstrong\u003ePremium Engineering Materials:\u003c\/strong\u003e Precision CNC-machined from a solid block of aircraft-grade aluminum, high-grade stainless steel hardware, and an ultra-smooth Delrin® Acetal Resin slider mechanism.\u003c\/li\u003e \n    \u003cli\u003e\n\u003cstrong\u003eDurable Mil-Spec Finish:\u003c\/strong\u003e Treated with a satin black hard-coat anodized surface layer for superior wear, scratch, and corrosion resistance.\u003c\/li\u003e \n    \u003cli\u003e\n\u003cstrong\u003eMade in the USA:\u003c\/strong\u003e Proudly manufactured to rigorous professional tolerances to ensure lifelong field and laboratory reliability.\u003c\/li\u003e \n\u003c\/ul\u003e \n\n\u003c!-- ===================== PRODUCT DESCRIPTION ===================== --\u003e \n\u003ch2\u003eProduct Description\u003c\/h2\u003e \n\u003cp\u003e \n    The premium \u003cstrong\u003e50mm Micrometer Adjusting Macro Rail\u003c\/strong\u003e cleanly resolves the intense challenge of managing a razor-thin depth of field in macro photography and focus-stacking workflows. Because minute shifts in distance completely alter the focal plane when shooting past life-size reproduction ratios, standard rack-and-pinion rails lack the necessary control. This stage overcomes that physical constraint entirely, utilizing a high-end \u003cstrong\u003eMitutoyo micrometer drive\u003c\/strong\u003e to translate your entire camera rig forward or backward in absolute 0.01mm micro-incremental steps.\n\u003c\/p\u003e \n\u003cp\u003e \n    A core mechanical advantage of this model is its fully customizable, indexable slider stage. By utilizing a unified locking center screw paired with heavy-duty anti-twist indexing dowel pins, the quick-release clamp can be re-oriented into \u003cstrong\u003e4 separate positions\u003c\/strong\u003e (90-degree steps). This flexible architecture lets you easily choose whether the clamp opens parallel or perpendicular to the adjustment axis, making it completely adaptable to varying camera brackets, base plates, or telephoto lens collars. Additionally, the micrometer barrel itself can be rotated to whichever orientation best suits your eye, allowing the engraved scale to face up, down, or sideways.\n\u003c\/p\u003e \n\u003cp\u003e \n    Engineered to confidently manage heavy professional setups, this macro rail features a completely rigid unibody frame that eliminates mechanical flexing or slop. The integration of premium \u003cstrong\u003eDelrin® Acetal Resin\u003c\/strong\u003e inside the slider track ensures nonabrasive movement and long-term wear resistance without requiring debris-trapping wet lubricants. Whether configured horizontally for field work up to 15 lbs, or locked vertically on a laboratory copy stand at a 4kg capacity, this USA-made focusing rail delivers the rock-solid tracking performance your extreme macro photography demands.\n\u003c\/p\u003e","brand":"Hejnar Photo","offers":[{"title":"Default Title","offer_id":67701616869481,"sku":"MS4-2","price":550.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/1278\/9353\/files\/0001_MS4-2.jpg?v=1793745476","url":"https:\/\/www.hejnarphotostore.com\/products\/50mm-micrometer-adjusting-macro-rail-mitutoyo","provider":"Hejnar Photo","version":"1.0","type":"link"}
