NiSi 105 mm True Colour Variable ND Filter 1 5 Aperture (ND2 ND32) VND Vario Neutral Density Filter, Optical Glass with Multi Nano Coating

Exclusive true colour coating: prevents the yellow tint that is common with other brand filters and ensures absolutely neutral colour rendering, so that no colour distortions occur No "X" effect: provides 5 fixed aperture levels (ND0.3-ND1.5) and allows gradual rotation of the filter without the dreaded "X" effect Multi-nano coatings: up to 20-layer, anti-reflective coatings for low reflections, water and oil resistant coating on both sides No vignetting: larger front thread to avoid vignetting on 16mm lenses, with a filter frame that has a matte black interior to effectively absorb stray light and reduce glare Knurled aluminium frame: the knurled edges of the lightweight, precision-machined aluminium frame of the NiSi variable ND filter allow better grip as well as easy assembly and disassembly
