Sirui Macro Focusing Rail MS18 macro rail

The Sirui MS18 is a focus rail designed specifically for close-up and macro photography. It helps you adjust the camera’s distance from the subject in a controlled manner when the focus range is small and fine-tuning is crucial.

Precise distance adjustment

The 180 mm long rail offers a 170 mm adjustment range. The stage moves by 1.25 mm per revolution, and the index marks engraved on both sides of the rail facilitate repeatable fine adjustment.

Arca-type mounting and flexible use

The Arca-style rail fits directly onto the head of an Arca-standard tripod. The rail can also be used on a table or attached to a tripod using removable leg spikes with a 3/8" or 1/4" thread.

Swivelling head for camera positioning

The 360-degree rotating head features angle locks at 90-degree intervals. The ergonomically designed Arca quick-release plate has locking blocks that help to secure the camera firmly in place.
