K&F Concept Nano-X Series 2-in-1 Variable ND & CPL Filter 72mm, 2 to 6-Stop (KF01.1916)

The K&F Concept 2-in-1 Variable ND + CPL Filter combines the functions of a variable ND filter and a CPL filter in one filter, providing both light reduction and improved color and contrast. The ND function offers 2–6 stops of light reduction, adjustable from ND4 to ND64, making it suitable for different lighting conditions, from cloudy days to extremely bright days. The CPL function helps remove unwanted glare and reflections from non-metallic surfaces while enhancing color and contrast.

The filter features self-locking technology with an infinitely rotatable adjustment mechanism to make light reduction and positioning easier while avoiding the common black “X” cross effect found in variable ND filters. It is especially designed to minimize this issue when using wide-angle lenses, including 16mm lenses.

The frame is made of CNC-machined aluminum alloy and features a push rod for convenient adjustment of the ND stop. The frame is marked with 5 stops from Min (ND4) to Max (ND64), making it easy to identify and adjust the desired ND level. For video users, the push-rod design can also help with adjusting the light reduction level using auxiliary tools.

The frame surface features an oxidation sandblasted finish, which helps reduce reflections and effectively minimize the entry of stray light. The filter is compatible with all 72mm lenses. Please verify your camera lens thread size before ordering; the number beside the “ø” diameter symbol indicates the lens thread size.
