The K&F Concept Variable ND filter operates on the same principle as a Circular Polarizer – rotate until you reach your desired effect and shoot. It allows you to have continuous control over the amount of light coming through your lens in an approximate range of 1 (ND 0.3) to 9 (ND 2.7) stops – while maintaining the integrity of your image.

Provides 1 to 9 stops of light reduction control.

Ultra Slim – 7.4mm.

Ultra-slim frame support no vignetting at 16mm focal length.

Comes in K&F Concept professional packaging with PU leather Case.

Made with Japanese imported optical glass using K&F Concept Nanotec technology.

Note:

When using the ND filter to the maximum(ND400) or bigger degree density, it will appear "X" spot or a blur in the picture, this is a normal phenomenon.

(Suggestion: Lower down the density value gradually and reduce the aperture, until the facula disappeared.)
