K-F CONCEPT Slim vario ND 2-400 variable gray filter 77 mm

The K-F Concept Slim Vario ND 2-400 is a variable neutral density filter with a 77 mm thread. Its adjustable light reduction lets you control exposure at the lens, so you can shoot with a wide aperture or a long shutter speed even in bright daylight. It suits photographers who want to work deliberately with motion blur or shape the colours and contrast of their images.

The filter has a slim, transparent housing and weighs only 70 g, so it adds little bulk to your camera kit. It is a practical choice for landscape and street photography, where it helps create atmospheric images with a smooth, even light effect.
