K&F 77MM CPL+MCUV+ND1000+Lens Cap Circular Polarizing Filter MCUV Protection Neutral Density Lens

This filter set includes MCUV + CPL + neutral ND1000 + 2× filter caps + 3× microfiber cleaning cloths. Filter diameter: 77 mm.

24 layers of coating & CNC frame

All filters are made from premium AGC optical glass imported from Japan. The glass is multi-coated on both sides, free from chromatic aberration (color shift), water-resistant, and oil-resistant.
The ultra-thin frame (1.9–3.5 mm) ensures zero vignetting and dark corners even when using a wide-angle lens with a focal length of 16 mm. The CNC frame with anti-slip coating makes installation and removal easy.

MCUV protective filter

The UV protective filter has two functions: it reduces the blue cast in images caused by UV radiation (98.6% transmission without affecting image sharpness or quality) and protects the lens from dust and scratches.

Circular polarizing filter (CPL)

Helps reduce glare from metal surfaces and increases color saturation and contrast. This effect is often used to deepen the blue color of the sky and highlight white clouds.

10-stop light reduction

Reduces the amount of light entering the lens by 10 stops, allowing for long exposure times and capturing the movement of objects such as waterfalls with a soft, silky water flow effect.
