K&F Nano C Series Variable ND Filter 67mm Blue Coating

The K&F Concept Blue Multi-Coated Variable ND Filter is a neutral density filter offering adjustable light reduction from ND2 to ND400. It uniformly darkens the entire image, allowing for wider apertures or slower shutter speeds than normally required. By slowing down the exposure time or increasing the aperture, it controls depth of field and effortlessly blurs motion, creating a dynamic look for waterfalls, cascades, landscapes, etc. This multi-layer variable neutral density filter doesn't alter image color. The filter's precision reduces vignetting risk on wide-angle lenses.
