K&F Concept 40.5mm 3-in-1 Multi-Function Filter

The K&F Concept 40.5mm 3-in-1 Multi-Function Filter combines a variable ND2-32, a CPL, and a Black Mist 1/4 diffusion filter in a single compact unit. Perfect for photographers and videographers, it allows precise exposure control, reduces glare, enhances color saturation, and adds cinematic softness to portraits, landscapes, and video footage.

The K&F Concept 40.5mm Nano C Series 3-in-1 Hybrid Filter is a versatile solution for creative photography and filmmaking. This professional-grade filter integrates three essential tools: a Variable ND2-32 for smooth exposure adjustments of 15 stops, a CPL circular polarizer to reduce reflections and enhance color and contrast, and a Black Mist 1/4 diffusion filter to soften highlights and produce a cinematic, dreamy effect. Made from premium AGC Japanese optical glass with 28-layer Nano-C coatings, the filter is resistant to water, dust, oil, and scratches, while the CNC-milled aluminum frame ensures durability and prevents vignetting or reflections. Advanced optical design eliminates the black X effect common in many variable ND filters, making it ideal for wide-angle lenses. Compatible with cameras from Nikon, Pentax, Olympus PEN, Samsung NX, and Sony NEX series, this hybrid filter is perfect for portraits, landscapes, long exposures, and cinematic video projects.
