The K&F Concept Variable + CPL and Black Diffusion Nano-X Series Filter (67mm) combines three essential features in one filter: variable ND, circular polarizer, and black diffusion. This versatile filter allows you to control light exposure, enhance color saturation, and add a cinematic diffusion effect. With its adjustable ND range from 0.6 to 1.8 Optical Density, it gives you greater flexibility in achieving the perfect exposure while also reducing reflections with the CPL element. The Black Diffusion layer softens highlights and creates a more cinematic look, perfect for both photography and videography.
Crafted from 28-layer multi-coated optical glass, this filter reduces glare and maintains image sharpness while providing natural color rendering. The slim design reduces vignetting, even on wide-angle lenses, and the aluminum ring ensures long-lasting durability. This is an ideal choice for photographers and videographers who want complete control over their images with a high-performance, multi-functional filter.
