Hoya HMC Neutral Density NDx4
The NDx4 filter reduces the light entering the lens by 2 stops. HMC (Hoya Multi Coating) has 3 layers of anti-reflective coating on each surface which reduce reflections down to 1-2%. In conditions of extreme light intensity, such as sunshine on snowy mountains or on the beach, or when using a camcorder, ND (Neutral Density) filters are recommended as essential.
