All NiSi Filters are precision engineered from the highest quality H-K9L Optical Glass.
Glass means they are completely distortion free and give the ultimate in image quality. All edges are double ground and polished and corners are rounded. IR technology in every filter provides True-To-Life colour with no cast by reducing the amount of Infra Red light entering the lens which can shift colour accuracy.
Nano coatings help to reduce lens flare, repel oil contaminations and water, making them easier to clean out on location.
Filters are available from Lenslight Nisi
