K&F Concept K&F filter HD Black Mist 1/4 K&F diffusion filter 67mm 67mm

The K&F Concept 67 mm Black Mist Diffusion Filter 1/4 Nano-X HD MRC is designed for portrait photography and video recordings. This professional filter creates a subtle softening effect that reduces skin imperfections while maintaining image sharpness. The 1/4 diffusion strength provides a gentle haze effect, ideal for dreamy, cinematic shots without excessive blur. Made from precise Japanese AGC optical glass with a double-layer coating for 84 percent light transmission, it effectively minimizes surface reflections and prevents vignetting. The optical glass is double-polished for high resolution performance within a 550 mm focal length range. A 28-layer nano-coating offers comprehensive protection against water, scratches, and oils for long-lasting durability and easy cleaning. The ultra-thin aluminum frame measures only 3.3 mm in width and avoids dark corners and vignetting even with wide-angle and telephoto lenses. CNC machining creates a curved frame design for better grip and slip resistance during mounting and adjustment. Compatible with all lenses with a 67 mm thread diameter. Please check your lens thread size before purchasing, typically marked on the lens barrel or under the lens cap. The Black Mist diffusion effect is particularly suitable for portrait sessions, wedding photography, and cinematic video production, where subtle softening enhances the overall aesthetic quality.
