K&F Concept Nano-X ND4 Green Multicoated Variable ND Filter (55mm)

The Nano-X ND4 Green Multicoated Variable ND Filter from K& F Concept is a 55mm variable neutral density filter providing an adjustable light reduction of 2 stops. It darkens the entire image evenly, allowing a photograph to be made with a wider aperture or slower shutter speed than normally required. By slowing the exposure time or increasing the aperture, it is possible to control the depth of field and convey blurred movement easily, creating a dynamic look for streams, waterfalls, landscapes, and more. This multicoated neutral density filter does not affect the coloration of the image, and it features a waterproof and scratch-resistant coating for durable performance in the field.

The filter is made with premium German optics glass.

The filter is constructed of aviation aluminum alloy, which is both super-slim and lightweight.

Avoiding vignetting on wide angle lenses.

The filter is comprised of an extra tough frame ensuring durability and jamming prevention.

It cuts polarized light to increase contrast and boosts color saturation and vibrancy. It also cuts 2 stops of light for motion blur and depth of field effects in bright light.

The Nano-X features features 18-layers of nano-coating significantly reducing lens flare and ghosting while providing easier cleaning and better protection against water, oil and scratches.

Hard coated multi-coating increase light transmission, which an be used to achieve super slow shutter speeds in daylight to render moving subjects invisible.

Enables slow shutter speeds to be used to record movement in subjects such as waterfalls. It provides a silky smooth affect to flowing water.
