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.\u003c\/p\u003e \n\u003c\/div\u003e\n\n\u003chr style=\"border:0; border-top:1px solid #ddd; margin:25px 0;\"\u003e \n\n\u003c!-- ===================== SAE TECHNICAL SPECIFICATIONS ===================== --\u003e \n\u003cdiv style=\"font-family:Arial, sans-serif; margin-bottom:25px;\"\u003e\n    \u003ch2 style=\"font-size:20px; color:#111; margin-bottom:15px; border-bottom:1px solid #ccc; padding-bottom:5px;\"\u003eSAE Technical Specifications\u003c\/h2\u003e \n    \u003cul style=\"padding-left:20px; line-height:1.8; font-size:14px;\"\u003e \n        \u003cli\u003e\n\u003cstrong\u003eBase Rail Length:\u003c\/strong\u003e 10.00 inches.\u003c\/li\u003e \n        \u003cli\u003e\n\u003cstrong\u003eBase Rail Thickness:\u003c\/strong\u003e 0.625 inch (5\/8\").\u003c\/li\u003e \n        \u003cli\u003e\n\u003cstrong\u003eLead Screw Resolution:\u003c\/strong\u003e 0.0416 inch (1.06mm) travel per full revolution.\u003c\/li\u003e \n        \u003cli\u003e\n\u003cstrong\u003eHorizontal Load Capacity:\u003c\/strong\u003e Up to 15 lbs (parallel to ground).\u003c\/li\u003e \n        \u003cli\u003e\n\u003cstrong\u003eVertical Load Capacity:\u003c\/strong\u003e Up to 10 lbs (perpendicular to ground).\u003c\/li\u003e \n        \u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e CNC-machined 6061-T6 Aluminum with Black Hard Coat Anodized finish.\u003c\/li\u003e \n        \u003cli\u003e\n\u003cstrong\u003eHardware:\u003c\/strong\u003e High-grade Stainless Steel.\u003c\/li\u003e \n    \u003c\/ul\u003e \n\u003c\/div\u003e\n\n\u003chr style=\"border:0; border-top:1px solid #ddd; margin:25px 0;\"\u003e \n\n\u003c!-- ===================== KEY FEATURES SECTION ===================== --\u003e \n\u003cdiv style=\"font-family:Arial, sans-serif; margin-bottom:25px;\"\u003e\n    \u003ch2 style=\"font-size:20px; color:#111; margin-bottom:15px; border-bottom:1px solid #ccc; padding-bottom:5px;\"\u003eQuick Overview \u0026amp; Key Features\u003c\/h2\u003e \n    \u003cul style=\"padding-left:20px; line-height:1.8; font-size:14px;\"\u003e \n        \u003cli\u003e\n\u003cstrong\u003eDual-Action Positioning:\u003c\/strong\u003e Press the slider release lever for fast coarse adjustments, then engage the lead screw for sub-millimeter fine control.\u003c\/li\u003e \n        \u003cli\u003e\n\u003cstrong\u003eSecure Locking Mechanism:\u003c\/strong\u003e Features a side lock to firmly secure the slider in place after achieving the perfect focus point.\u003c\/li\u003e \n        \u003cli\u003e\n\u003cstrong\u003eModular Quick Release Clamp:\u003c\/strong\u003e 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).\u003c\/li\u003e \n        \u003cli\u003e\n\u003cstrong\u003eUniversal Arca-Swiss Base:\u003c\/strong\u003e Integrated bottom dovetail fits industry-standard quick release clamps from RRS, Kirk, and Wimberley.\u003c\/li\u003e \n        \u003cli\u003e\n\u003cstrong\u003eNodal Slide Functionality:\u003c\/strong\u003e Optimized design allows it to serve as a precise nodal slide for professional panoramic stitching.\u003c\/li\u003e \n    \u003c\/ul\u003e \n\u003c\/div\u003e\n\n\u003chr style=\"border:0; border-top:1px solid #ddd; margin:25px 0;\"\u003e \n\n\u003c!-- ===================== PRODUCT DESCRIPTION ===================== --\u003e \n\u003cdiv style=\"font-family:Arial, sans-serif; line-height:1.6; color:#333;\"\u003e\n    \u003ch2 style=\"font-size:20px; color:#111; margin-bottom:15px; border-bottom:1px solid #ccc; padding-bottom:5px;\"\u003eDetailed Product Description\u003c\/h2\u003e \n    \u003cp style=\"font-size:14px; margin-bottom:15px;\"\u003eThe 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.\u003c\/p\u003e \n    \n    \u003cp style=\"font-size:14px; margin-bottom:15px;\"\u003eReliability 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.\u003c\/p\u003e \n    \n    \u003cp style=\"font-size:14px;\"\u003eThis 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.\u003c\/p\u003e \n\u003c\/div\u003e","brand":"Hejnar Photo","offers":[{"title":"Default Title","offer_id":67701615132777,"sku":"MS3_10","price":375.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/1278\/9353\/files\/0001_MS3_10.jpg?v=1793750567","url":"https:\/\/www.hejnarphotostore.com\/products\/0-inch-single-stage-lead-screw-macro-rail","provider":"Hejnar Photo","version":"1.0","type":"link"}
