Key Features

The SIRUI MS18 Macro Focusing Rail is a precision tool built for focus stacking, letting macro shooters combine several shots at different focal points into one sharp image in post. Its solid aluminum construction supports camera and lens combinations up to 10kg while weighing only 440g itself, aimed at macro photographers who need both large sweeping adjustments and fine 0.01mm precision on the same rail. A 360-degree rotating head and Arca-type plate add compatibility with existing tripod hardware.


  • Supports up to 10kg (22.05lb): Hollow-out aluminum bottom plate keeps the rail itself to just 440g (0.97lb).
  • 170mm travel range on a 180mm rail: Engraved index marks on both sides enable fine adjustments.
  • Large and minor adjustment modes: Push-button for quick large moves; thumb-screw knob delivers 1.25mm per revolution, down to 0.01mm precision.
  • 360° rotating head at 4 angles: Clamp locks securely in place after every 90 degrees of rotation.
  • Arca-type double-dovetail plate: Works with most Arca-type clamps, with detachable feet for tabletop use.
