The K&F Concept 52mm Multi-Function Black Mist 1/4 & ND8128 Filter is designed for creators seeking a compact, all-in-one tool that enhances both the artistic and technical quality of their images. This dual-purpose filter functions as a Black Mist 1/4 diffusion filter softening highlights, reducing contrast, and adding a cinematic glow and as a variable ND filter with a 37 stop adjustment range (ND8128). Crafted with top-grade optical glass and protected by a double-sided 28-layer anti-reflection coating, it minimizes glare while maintaining an impressive 84 transmittance, ensuring clean, sharp imaging even at telephoto focal lengths. The ultra-thin 7.4mm aviation-aluminum frame eliminates vignetting and features a CNC-machined trapezoidal pattern for superior grip and smooth, precise adjustments. With durable coatings that are waterproof, anti-scratch, anti-oil, and anti-mildew, this filter is built for demanding environments and provides exceptional clarity and ease of use for both still photography and video production.
