KF 77mm Hybrid 3-in-1 Filter ND2-32 + CPL + Black Diffusion 1/4

This 77mm hybrid filter merges a variable neutral density filter (ND2–ND32, 1–5 stops), a circular polarizer, and a black diffusion 1/4 element into a single ultra-slim ring. It delivers precise exposure control, glare reduction, and cinematic highlight softening in one tool, ideal for landscape, portrait, and video work.

Advantages

The multi-layer coated high-definition optical glass ensures neutral colour rendition and high clarity. Water-, oil-, and scratch-resistant coatings protect the surface during outdoor shoots. The aviation aluminum alloy frame is both lightweight and robust, while the double-threaded design allows stacking additional filters or lens caps. No vignetting occurs at wide angles thanks to the ultra-slim profile.

Suitable for

• Landscape photographers balancing sky and foreground exposure
• Videographers needing smooth exposure transitions without changing aperture
• Portrait artists seeking soft, diffused highlights and reduced reflections
• Travel shooters wanting a versatile all-in-one filter solution

Key specifications

• Filter diameter: 77mm
• ND range: ND2 to ND32 (1–5 stops)
• Polarizer type: Circular (CPL)
• Diffusion strength: Black Diffusion 1/4

Recommendations

For best results, rotate the filter ring to adjust polarisation and ND density simultaneously. Use the black diffusion effect sparingly in high-contrast scenes to preserve detail while softening highlights. Always clean with a microfiber cloth to maintain coating integrity.
