K&F Concept Black Diffusion 1/8 -suodatin 4x5.65 inch Matte Box -kehykseen

The K&F Concept Black Diffusion 1/8 Filter is a professional-grade optical filter designed for use with standard 4x5.65 inch matte boxes. Crafted from high-definition optical glass with multi-layer nano coating, this filter softens skin tones, reduces blemishes, and adds a subtle cinematic glow to highlights while lowering overall contrast. Ideal for filmmakers and videographers seeking a dreamy, filmic look without significant light loss.

Advantages

This filter provides a delicate diffusion effect (1/8 strength) that smooths skin imperfections and creates a soft, ethereal atmosphere. The multi-layer nano coating repels water and oil, making it easy to clean and maintain. Scratch-resistant and anti-reflective, it ensures high optical clarity and durability on set.
