Colour Cast Performance
Worlds Sharpest ND Filter. 100% Guaranteed.
The X4 ND features SCHOTT Superwhite B270 optical glass, which is an ultra clear crown glass. It is produced by melting high purity raw materials and then made using the continuous draw process. The result is excellent transmission in the ultraviolet, visible, and infrared spectrums, and a high surface quality that accepts our state-of-the-art MRC and nanotec coatings exceptionally well.
Most of the neutral density filters on the market exhibit a strong blue or magenta cast. The higher the ND factor the more pronounced the colour cast.
The X4 ND has the most neutral color transmission throughout the visible range and well into infrared.
