K&F Concept Black Mist 1/4 Diffusion Filter (40.5mm)
Create Soft, Cinematic Highlights with Subtle Contrast Reduction

Enhance your imagery with a cinematic, dreamlike quality using the K&F Concept Black Mist 1/4 Diffusion Filter. Designed to soften harsh light and reduce contrast, this filter adds a gentle glow around highlights while maintaining image clarity. Ideal for portraiture and creative filmmaking, it smooths skin tones by minimizing the appearance of wrinkles, freckles, and pores—producing a more flattering, ethereal look.

• Soft Glow Effect with Lowered Contrast
  Produces delicate highlight flares and reduces overall contrast, helping to create a misty, cinematic aesthetic without losing detail.

• 18-Layer Multi-Coating
  Nanometer coatings on both sides of the glass provide scratch resistance, water and oil repellency, and anti-reflective properties—ensuring durability and optimal light transmission.

• Premium Japanese AGC Optical Glass
  Constructed from imported AGC glass for high-quality optical performance. Dual-sided coatings maintain 84% transmittance with no color shift, preserving image fidelity.

• Ultra-Slim Aluminum Frame
  Built with lightweight aviation-grade aluminum alloy, the filter features a 3.3mm profile to prevent vignetting, even on wide-angle lenses. CNC-machined with a non-slip grip for easy installation and removal.

• Lens Compatibility
  Designed for lenses with a 40.5mm thread. Please confirm your lens size before purchase—the filter thread size is typically marked on the lens barrel next to a “ø” symbol.
