ND8 (3 Stop) Square Filter Plus+

You can use one filter system across all your lenses.

Square filter systems are made up of a square filter, a filter holder and a filter adapter to attach it to your lenses. You can buy adapters rings that let you attached the square filter holder with different sizes of lenses. This means you can invest in a better quality neutral density or polarizing filter because you can use it across all lenses instead of buying multiple filters for each lens.

Anyone with a broad collection of lenses, landscape photographers and those who value quality over a minimalist camera bag.

Square filters can be much cheaper than circular filters if you use a broad range of lenses because you can use the one set of filters across all of provided you have the right filter adapters to connect your filter holder to the different sized lenses. Square filters are popular with landscape photographers too because you can, for example, adjust the height of a graduated ND filter in the filter holder to better suit the lighting conditions. Square filters are bulkier and slower to set up so aren’t to those who prefer a light kit and moving quickly.

There are three elements to a square filter system: the filter itself, the filter holder, and the filter adapter that connects to your lens.

You can use your square filter with different size lenses if you buy different sized filter adapters. These allow you to connect your filter holder to your lens. You then insert filters into the holder and you’re ready to shoot. Filter holders let you stack multiple filters so you can combine neutral density filters and polarizing filters.
