- - 【Optical Glass GND8】the 3 stops nd filter is made of Germany's top optical glass, with a transmittance of 12.5% and a reflectivity of 1.5%. Due to the precision grinding double-sided polishing, high-definition imaging is guaranteed.
- - 【Function】Grad ND is suitable for large light ratio contrast between the sky and the ground. If the ground is normally exposed, the sky will be heavily burdened. The soft gradient filter can effectively balance the light ratio and contrast.
