This Variable ND Filter from K&F Concept is a 62mm variable neutral density filter providing adjustable light reduction from 5 to 9 stops. This multi-coated filter reduces the entry of light and does not affect the coloration of the image. Allowing greater control for long exposure and motion blur techniques in changing light, it is possible to create a dynamic look for waterfalls, landscapes, and more. The filter's slim design reduces possible vignetting, and the K&F peak technology avoids images with inconvenient x cross. Made of optical glass combined with an aluminum alloy frame, this filter is also green film anti-reflection, waterproof, and oil and scratch resistant.
