K&F Concept B-Series Variable ND2–ND400 (77 mm) threaded adjustable neutral density filter reduces the amount of light entering the lens and allows you to vary the density. To select the density, set the dedicated ring to one of nine positions. Useful in bright sun, allowing you to shoot with a wide-open aperture and use longer shutter speeds to create motion effects, for example the “milky water” look.
Included: K&F Concept B-Series Variable ND2–ND400 77 mm filter, carrying box.
