Filter system manufacturer Nisi has introduced a new filter holder that allows photographers to rotate two filters independently of each other, in much the same way that Lee’s Tandem operates. The Nisi Switch attaches to the existing 82mm filter holder and provides an additional rotation point so that the forward filter can be twisted separately to filters in the main holder.

The system is designed for those using graduated filters to make tackling mountainous horizons easier and so that graduated filters can be placed at more than a single angle to allow photographers to control different areas of the scene individually.

The Switch is part of the company’s 100mm filter system and will cost around $ 99. Those without the current 82mm filter holder will also need to buy a V6, a V5Pro or a V5 kit as well. These kits start at $ 169. For more information see the Nisi website.
