This 77mm Nano-X Variable ND Filter from K&F Concept is a variable neutral density filter with a range of 1 to 5 stops. The density can be continuously adjusted by rotating the knurled aluminum ring. Increasing exposure density allows the use of a wider aperture setting, providing finer control over depth of field, which can help isolate the subject of an image. Increased density can also be used to lengthen shutter speed to enhance motion blur, as when shooting moving water. A variable density filter is also useful to control camera frame rates when shooting video.

This filter is constructed with premium-grade Japanese optical glass for optimal light transmission and resolution with no added coloration.

28 layers of multicoating prevent flare and glare, allowing optimal light transmission and saturation. In addition, the nano-coating layer technology repels dirt, water, and other elements by beading up rather than absorbing and smearing. The nano resistance coating protects against saltwater, dust, wind, scratches, and other abrasive conditions and elements, making it ideal for use in harsh environments and locations.

Advanced filter technology eliminates the common "X" effect issue that often appears when using variable ND filters on wide-angle lenses.

The filter ring is crafted from aviation-grade aluminum for smooth rotation, it features a density scale and a knurled edge for easy gripping and rotation.
