A macro focusing rail lets you move your whole camera setup closer to or further away from your subject in very fine increments in order to shift the plane of focus exactly where it needs to be to capture the detail you want.įor the second problem, because of the movement that macro focusing rails allow, you can create a series of images at different distances from your subject, shifting the plane of focus through it as you shoot. If you are just looking to pinpoint a specific part of your subject in a single photo, with the depth of field so shallow, it’s easy to miss your target (even with an autofocus lens), especially if handheld but even when using a tripod. You’re rarely going to get your whole subject sharp front-to-back because you just can’t get enough depth of field.Īnd this is where a macro focusing rail steps in.

On one end is a simple round knob, while the other has a handle with a collapsible knob that makes it a little more obvious just how far you’re actually turning it each increment.Įach full revolution of the handle or knob moves the platform 1.25mm, allowing for some very fine movement increments. On each end of the NM-180 is a knob to rotate the threaded rod that runs the length of the unit. This head can also rotate a full 360° so that you can track towards or away from a subject or from one side of it to the other for capturing wide views of flat objects. On top of the carriage that runs along the rail is an Arca Swiss compatible mount (with a very nicely machined plate) into which you can mount your camera and lens. So, if you’re using an Arca Swiss compatible head, you don’t need to bother with tripod plates at all. And the feet are removable, too.Īnother option for tripod-mounting the focusing rail is that the entire thing essentially has a built-in Arca Swiss compatible plate. When you do want to, there is a 3/8-16″ socket underneath with a 1/4-20″ adapter allowing you to mount it to whatever plate you wish. You can still attach it to a tripod, too, but you don’t have to. As I mentioned, the NiSi NM-180 has some thoughtful design features that offer the user a lot of versatility when it comes to how they want to use it.įirst off, there are four feet on the bottom of it, meaning that you can stand it straight on a desk without having to go through the hassle of mounting it to a tripod and then levelling it. Before we take a look at the issues of shooting macro that a focusing rail solves, let’s take a quick look at the NiSi NM-180 and its features.
