【4-pack ND Filter Set】Fixed ND Filter Kit: ND4(2 stop), ND8 (3 stop), ND64 (6 stop), ND1000 (10 stop) and 1 x filter pouch.

【Filter function】Neutral Density filters' effect is to weaken the amount of light passing through the lens to reduce exposure. Where there is a lot of light and you want to shoot with a wide aperture, you can add a ND Filter to extend the shooting time, for example, shooting foggy running water in a very bright place.

【HD Optical Glass】AGC optical glass effectively reduces reflections and ghosting on the filter surface, ensuring high quality images.

【Multi-layer Coating】Double-sided nano-coating for almost zero light distortionwhile making the filter scratch, water, oil and dust resistant.

【No Vignetting】The ultra-thin aluminium filter frame minimises the effect on light, effectively avoids vignetting for wide-angle shooting, keeping the true color.
