Overview
The 77mm, 1/4-grade K&F Concept Black Diffusion Filter reduces highlight values and slightly lowers overall contrast. Ideal for fashion and beauty applications in photography and video, it smooths and softens facial wrinkles and blemishes while maintaining high-definition image quality.
Core Features
The filter allows for 84% light transmittance, offering a soft, pastel-like quality of light. It provides more contrast and highlight reduction than the 1/8 density but less than the 1/2 density.
Build Quality
Constructed with high-quality optical glass, the filter includes 28 multicoated layers, making it waterproof, scratch resistant, and oilproof. It is encased in a slim, aviation-grade aluminum frame with machined grooves for easy handling.
