K&F Concept 49mm ND8-2000 Nano-D Variable ND Filter with Multiresistant Coating 3-11 Stop KF01.1353

Key Features

• Variable 0.3 to 33 Optical Density
• 24-Layer Multicoating
• Waterproof and Resistance Coating
• Japanese Optical Glass Construction
• Aviation Grade Aluminum Filter Ring
• Darkens Entire Image Area
• Allows Reduced Shutter Speed
• Allows Wider Aperture

This 3- to 11-Stop Nano-D Variable ND Filter with Multiresistant Coating from KF Concept is a 49mm 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 without overexposing the image. 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. This adjustable filter is especially useful when shooting landscapes and in very bright light conditions, and it is useful for both still and video imaging.

Variable 3 to 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.

Mulitresistant, Waterproof Coating

Both the front and rear surface of this filter feature a multiresistant 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 it features a density scale for ease of use.
