It is a Graduated Neutral Density filter that can be used in scenes with a horizontal composition, such as the cityscape on both sides and the sun rising between the mountains. It is designed to be used with 100mm filter holder system in horizontal composition to get the triangle GND effects. The maximum ND value is ND 0.9 (3 stops under exposure).
Coating is Premium Quality.
The world's highest level of low-reflection coating is applied to reduce ghost and light flare.
German-made B270 optical glass is used for high transmittance, and high flatness accuracy is maintained by double-sided ultra-precision polishing.
Visible light transmittance is extremely high, and it is designed to have very little bluish tint during long exposure photography. Realize that this is different from the general one. It has an extremely strong oil-, water-, and dust-proof coating that can be wiped with a regular cloth.
