K&F Concept 37/40.5/43/46/49/52/58mm Fader ND Filter Neutral Density Variable Filter ND2 to ND32 for Camera Lens with NO X Spot Nanotec Ultra-Slim Weather-Sealed for Sony Canon Nikon DSLR Camera

Product Description

ND-------Extend exposure time. Try an ND, or neutral density, filter. ND filters reduce the amount of light entering the lens. This makes it easier to achieve effects such as a shallower depth of field or blurred motion.

Neutral density can be adjusted from 2 to 5 stops, easy to create different neutral density by rotating the ring.

The front diameter is larger than the back diameter of this filter , which is specially designed to avoid vignetting at wide angle lens.

Allows the use of slow shutter speeds, with high speed films or digital cameras, to record movement/image blur in subjects.

Decrease the depth of field by using wider apertures, which helps separate subjects from their background.

No "X" cross on images

K&F utilize cutting edge technology you're going to say goodbye to this common issue with wide angle lenses and variable ND filters.

Nano Coating

In addition to state-of-the-art MRC, our optical engineers developed new nano coating layer technology, called nanotec, from the ground up to repel dirt, water and other elements by beading rather than absorbing and smearing. Set in our workhorse and built to withstand extreme wind, salt water, dust and other abrasive conditions and elements.
