The SW150 filter holder comes assembled with two filter slots, enabling you to use neutral density graduated filters in combination with other filters.
The holder also comes fitted with a Lightshield. The shield helps to prevent unwanted back reflections and creates a light tight seal enabling the use of both the Little and Big Stopper.
Due to the size of the front element of ultra-wideangle lenses, the filters for the SW150 system are larger than those in the standard 100mm rangeGraduated filters are 150 x 170mm, whilst standard filters, the Little and Big Stopper and the Polarizer are 150 x 150mm.
