KF 40.5mm Hybrid 3-in-1 Filter: Variable ND2-32, Circular Polarizer, Black Diffusion 1/4

This 40.5mm hybrid filter combines three essential tools in one: a variable neutral density filter (ND2-ND32), a circular polarizer, and a 1/4 black diffusion filter. It delivers precise exposure control, glare reduction, and cinematic softness without swapping filters.

Advantages

The variable ND range from 2 to 32 (1 to 5 stops) lets you shoot wide open in bright light or capture motion blur in video. The circular polarizer cuts reflections and enhances color saturation, while the 1/4 black diffusion softens highlights and reduces skin imperfections for a flattering, filmic look. Multi-layer nano coatings repel water, oil, and scratches, and the ultra-slim aviation aluminum frame prevents vignetting on wide-angle lenses.

Suitable for

• Landscape and outdoor photographers needing glare control and long exposures
• Portrait and wedding shooters seeking soft, cinematic skin tones
• Videographers adjusting exposure smoothly during a shot
• Travel photographers who want one filter for multiple effects

Recommendations

For best results, rotate the front ring to adjust ND density and polarization independently. Clean with a microfiber cloth; avoid harsh solvents. Ideal for lenses with 40.5mm filter threads.
