While more commonly known for their filters and their upcoming cine lenses, NiSi recently announced their new NM-180 Macro Focusing Rail. Focusing rails are essential pieces of kit for serious macro photographers that allow them to create images that might otherwise be impossible, but how well does the new NiSi NM-180 stack up? Maybe pun intended.
I’ve been using the NiSi Macro Focusing Rail for a few weeks now. The short version of this review is that for what it costs, it’s an extremely well-made device, that has some thoughtful design considerations and does exactly what it’s supposed to. In my opinion, it’s well worth what it costs. But how do focusing rails work and why do you need one?
