feature: 1. ND-2: 1st gear, 50% less light; 2. ND-4: 2 stops of aperture, reducing light by 75%; 3. ND-8: It can reduce 3 stops of aperture and 87.5% of incoming light; 4. ND-400: Can reduce the amount of light by 9 stops, suitable for long exposure during the day and shooting the sun 5. When the focal length of the lens is in the ultra-wide-angle range and the aperture value is F2.8, if the filter is adjusted to the maximum density for use, more obvious "cross" flares or slight color shift may appear. In order to ensure that the image is not disturbed, it is recommended to reduce the density value of the filter at this time until the disturbing light spot disappears, and then you can shoot normally. scope: Diameter: 82mm Weight: 105g Material: aluminum magnesium alloy, optical glass Colour: Black Keywords: ND filter, ND filter, ND filter, lens, photographic equipment 82mm Neutral Density Variable Graduated Filter Lens ND2 ND4 ND8 ND400 feature: 1. ND-2: 1 stop down and 50% lower light output 2. ND-4: Can reduce the secondary aperture and 75% of the light output 1. ND-8: 3-stop reduction and 87.5% light output 1. ND-400: Can reduce 9 stops of aperture and the corresponding amount of light, suitable for long exposure during the day and shooting the sun 5. When the lens is zoomed to the ultra-wide-angle range, the aperture is F2.8, and the filter lens is adjusted to the maximum density, the lens may have obvious +-shaped flare or slight color shift. Decrease the density of the filter lens until the point of light disappears, allowing you to shoot normally and make sure the image is undisturbed.
