Filter kits combine square filters, a filter holder and often adapter rings or a case in one purchase. This category includes Cokin NXS, Nuances Extreme, M Traveller, L and Z-Pro kits, black-and-white and infrared photography kits, and the NiSi 100 mm system V7 kit.

A kit is a convenient start for landscape photography, typically including C-PL, ND and graduated ND filters (for example GND2, GND4, GND8). Choose a kit by system size (M, L or 100 mm) and check that the included adapters, such as 72, 77 and 82 mm, fit your lenses.
