Focusing Rail for Macro Photography
Following the unprecedented popularity of the NiSi Macro Close-Up Lens for 67, 72 and 77mm lenses, we have once again listened to our customers and produced the NiSi NM-180s Macro Focusing Rail. The biggest challenge facing macro photographers is holding the camera perfectly steady in 3D space. Moving even a millimetre can throw the shot, so it’s easy to lose critical focus even with a tripod. This is where the focusing rail is essential. It gives you precise control over the distance between lens and subject. The NiSi Macro Focusing Rail has an adjustment range of 125 to 145mm subject to plate configuration (1mm travel per revolution.) and can be used on a flat surface or remove the studs to secure it to a tripod. For dual-axis control, you can stack two systems at 90º to each other.
We continuously improve our products, some details may differ between the photos on this page and the actual latest product.
Features
The NiSi Macro Focusing Rail is compatible with the Arca-Swiss dovetail mount and is equipped with an integrated Arca-Swiss type quick release foot-plate and clamp. The long plate for telephoto mounts is ergonomically designed for easy locking and release, and the bottom of the rail includes 3/8” and ¼” mounts for all compatible tripod heads, along with four (removable) studs allowing use directly on a tabletop. The rail has an adjustment range of 125 to 145mm subject to plate configuration (1mm travel per revolution) via the collapsible main thumb-screw or end-screw and a 360º rotating head. Both sides of the rail have engraved index marks to further aid precise positioning.
Construction
The NiSi focusing rail is made of high-precision CNC-machined aluminium and has a corrosion-resistant anodised finish. 
Thanks to the 3/8″ and 1/4″ screw attachment, the Macro Rail NM-180s is compatible with most tripods. The plate, which rotates 360°, can also hold telephoto lenses and the movement distances are conveniently engraved on the side of the rail.

4 Way Macro Focusing Rail?
For the most demanding photographers who require accurate dual axis movement, we recommend the purchase of 2x (two) NiSi NM-180s rails. This perfect combination of two slides delivers total freedom of movement, with top of the range features, high quality and an amazing price thanks to the NiSi model.

Nicely made bit of kit, an essential for higher than 1:1 focus stacking. The first example sent had a slightly bent worm screw resulting in a rough and squeaky travel, but fair play they sent a replacement by return, which is smooth as butter.

Great little macro rail. Really nice smooth dial for adjustments and a nice size for small movements. Really nice build quality and solid once clamped on my tripod.

A well engineered piece of kit that does (almost) what it says in the description. My ‘almost’ comment refers to the four legs because I cannot imagine a situation where I would want to free-stand the unit+camera. My preference would be to have four straight pillars, threaded at the top like the current legs, but drilled and tapped at the bottom to allow the rail to be bolted to a surface.

Lovely engineering. Well made and easy to use.
