NiSi 150x150mm ND filters

NiSi 150x150mm neutral density filters are the ideal tool for your long exposures with ultra-wide lenses.

Optical glass, not resin: surface coatings absorb the light, with no colour casts and minimal impact on sharpness. 150mm wide and 2mm thick, for the NiSi S6 holder with polariser, for ultra-wide lenses without a filter thread, and for other brands’ holders of the same size.

How many stops do you need?

Better than the case it comes with as I can keep filters with the holder much better.

These filters are IMO the best out there. Wish they would give me some discounts though with the money ive spent over the years (hope your reading this @NiSi lol). I have 7 filters with the V7 and V5 holders as well as adding the S6 for my fujfilm 8-16 lens. Hoping over the coming months it'll get used to its fullest potential.
