K&F CONCEPT 77mm ND8-ND2000(3-11stop) Lens Filter Variable Neutral Density

Variabel Neutral Density Filter ND8-ND2000
1. ND-----------Extend exposure time. Try an ND, or neutral density filter. ND filters reduce the amount of light entering the lens. This makes it easier to achieve effects such as a shallower depth of field or blurred motion.
2.Neutral density can be adjusted from nd8 to nd2000, easy to create different neutral density by rotating the ring.
3.Allows the use of slow shutter speeds, with high speed films or digital cameras, to record movement/image blur in subjects.
4.Decrease the depth of field by using wider apertures, which helps separate subjects from their background.
5.The MIN denotes ND8 (3 f-stop) and the MAX denotes ND2000(11 f-stops),gives you full control over your content.
