K&F Concept Nano-C Series 3-in-1 VND2-32 + CPL + Black Mist 1/4 Filter 49mm (KF01.2062)

The K&F Concept Nano-C Series 3-in-1 Filter 49mm puts the three filters a video shooter actually uses into one mount: a variable ND for exposure, a circular polarizer for reflections, and 1/4 black mist for highlight bloom. One filter on the lens instead of a stack that vignettes.

Density runs ND2 to ND32, which is 1 to 5 stops, enough to hold a 180-degree shutter outdoors at a wide aperture. The polarizer rotates independently, so cutting glare does not change your exposure setting.

Coated with 18 layers of green coating and engineered without the black cross across the usable range. Threads onto compact primes such as 50mm f/1.8.
