K&F Concept 82mm ND8 to ND2000 Nano X Variable ND Filter with Multi Resistant Coating

This ND8-ND2000 Nano-X Variable ND Filter from KF Concept is a 77mm variable neutral density filter that provides an adjustable light reduction of 3- to 11-stops. It darkens the entire image area evenly, allowing a photograph to be made with a slower shutter speed or wider aperture than normally required. Slowing the shutter speed increases the exposure, making it possible to increase image blur to emphasize motion, as when shooting flowing water. Alternately, when increasing the aperture provides finer control over depth of field, useful when trying to isolate the subject or increase bokeh. This adjustable filter is especially useful when shooting landscapes and in very bright light conditions, and can be used for both still and video imaging. Variable 3-11 Stops This ND8-ND2000 variable neutral density filter has a filter factor range of 0.9 to 3.3, providing an exposure reduction from 3- to 11-stops. It can help add motion blur and reduce depth of field when shooting still images, and to select a proper frame rate when shooting video. Japanese Optical Glass The filter is made of Japanese AGC optical glass for the same high level of image quality as the lens it is used on. Mulit-Resistant, Waterproof Coating Both the front and rear surface of this filter feature a multi-resistant coating that repels dust and grime and protects for fine abrasions. The coating is also waterproof and oil resistant, making it easy to use and keep clean, even in hard environments. 24-Layer Multicoating The optical glass filter features a total 24 layers of multicoating for optimal light transmission and color saturation, without color shift. Aircraft Grade Aluminum Alloy Filter Ring The super lightweight CNC-machined filter ring is only 7.5mm thick, and features a density scale for ease of use.
