K&F Concept 67mm 3-in-1 hybride filter: variabele ND2-32 + CPL + Black Diffusion 1/4 (KF01.2067)

The K&F Concept 67mm 3-in-1 Hybrid Filter combines three essential photographic tools into one ultra-slim, high-performance filter. Designed for lenses with a 67mm filter thread, this innovative filter integrates a Variable Neutral Density (ND2-32, 1-5 stops), a Circular Polarizer (CPL), and a Black Diffusion 1/4 filter. It eliminates the need to carry multiple filters, saving time and space while delivering professional results.

Advantages

This hybrid filter offers unparalleled versatility: adjust exposure and depth of field with the variable ND, enhance color saturation and reduce reflections with the CPL, and achieve a cinematic soft-focus effect with the Black Diffusion 1/4. The multi-layer nano coatings ensure water and oil repellency, scratch resistance, and anti-reflection, maintaining image clarity. The aviation aluminum alloy frame is durable yet lightweight, and the ultra-slim design prevents vignetting even at wide angles. A key feature is the absence of 'X' cross vignetting at maximum ND density, ensuring consistent performance.

Suitable for

• Landscape photographers needing long exposures and polarized skies
• Videographers requiring smooth ND transitions and reduced glare
• Portrait photographers seeking a soft, dreamy look with diffusion
• Travel photographers wanting a compact, all-in-one solution
