By moving the entire camera rig instead of the lens focus ring, this rail allows for precise focus stacking while maintaining a consistent reproduction ratio. With an overall length of 10.50 inches and a 3.5-inch maximum travel distance (88mm), it provides a generous range of movement for complex macro subjects.\u003c\/p\u003e \n    \n    \u003cp style=\"font-size:14px; margin-bottom:15px;\"\u003eDurability is at the core of this design. The rail utilizes self-aligning linear sleeve bearings with a PTFE liner, ensuring smooth, friction-free movement without the need for traditional grease that can attract dust and debris. The aluminum housing is treated with a specialized 0.002\" ceramic coating, making it highly resistant to corrosion and wear in challenging field conditions.\u003c\/p\u003e \n    \n    \u003cp style=\"font-size:14px;\"\u003eThe integrated precision scale allows for repeatable alignment, which is critical for scientific and industrial workflows. The bottom rail dovetail interfaces seamlessly with Arca-style tripod heads, while the top quick-release clamp can be repositioned in four different orientations. Whether you are balancing a heavy telephoto setup horizontally or shooting at a vertical 90-degree angle, this rail offers the stability and control needed for razor-sharp macro results.\u003c\/p\u003e \n\u003c\/div\u003e","brand":"Hejnar Photo","offers":[{"title":"Default Title","offer_id":67701617098857,"sku":"MS5PS_8-MS","price":375.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/1278\/9353\/files\/MS5P-8-MS-6.jpg?v=1793670416","url":"https:\/\/www.hejnarphotostore.com\/products\/8-inch-screw-adjusting-macro-rail-with-scale","provider":"Hejnar Photo","version":"1.0","type":"link"}
