# Title: Sirui MS18 Macro Focusing Rail ## Description: The MS18 Macro Focusing Rail from Sirui is a precision linear motion lead screw focusing stage and rail, incorporating a camera platform with a rotating Arca-type quick release set. The rail has a capacity of 6.69" of travel distance, each full rotation of the crank providing 1.25mm of movement for precise camera positioning. The focusing knob has a crank handle that conveniently folds flat. The rail has a hollowed-out design to reduce weight, but it still maintains a robust 22 lb load capacity. The base of the rail features an Arca-type dovetail, making it easy to mount on compatible devices. It also has four removable, rubber-tipped feet for tabletop use. The camera platform has a locking lever and incorporates an Arca-type quick release clamp that can be quickly rotated into four positions in 90° increments. The included quick release plate has traction pads to resist movement between the plate and camera body. ## Product type: * RETAIL - Lens Accessories - Macro Accessories ## Vendor: Sirui ## Tags: ## Price range: 109.0 - 109.0 USD ## Link: https://procam.com/products/sirui-ms18-macro-focusing-rail ## Compare-at price range: 99.0 - 99.0 USD ## Options - Title: Default Title ## Variants - Default Title, SKU: MS18, Available: yes, Inventory: 8, Delivery profile: - ## Metafields - description_excerpt: - whats_included: - specifications:
