The Nisi S6 system is designed for landscape photographers who would like to have a filter system for ultra-wide-angle lenses. Specifically for those without a regular filter thread. The system comes with a rotating CPL (circular polarizer), and it allows the use of two more filters. The S6 is a new iteration of a (similarly named) S5, and it features a few improvements.
Let’s first have a look at the improvements and then discuss the handling and use of the S6 system. We will also have a look at a few sample images.
