The Nisi F-Stopper Pro 4x4" (100x100mm) ND1000 (3.0) square glass filter provides 10 stops of Neutral Density filtration. It is compatible with any standard 4x4" filter system including the Nisi lens mounted filter folder, the Lee/Hitech/Cokin systems and matte boxes with 4x4" filter trays.
Nisi has become a leading manufacturer of professional level camera filters, their multi-coated filters providing performance levels similar to expensive brands such as Hoya. A combination of Japanese glass and a sophisticated multi-coating process produces high transmittance levels across their range of coated filters and a minimum of unwanted reflections, glare and artifacting.
