Irix Edge Black Mist 1/4 Filter SR (77mm)

The Irix Edge Black Mist 1/4 Filter SR is a 77mm diffusion filter that softens highlights and lowers contrast for film and photo work, built with a reinforced tempered-glass (SR) construction for durability.

• Diffusion Strength: Applies a 1/4-strength Black Mist effect, one of three Irix intensity options (1/2, 1/4, 1/8).
• Look: Diffuses light and lowers contrast while preserving darker image elements, creating a subtle halo around bright light sources.
• Coating: Optical glass with 18 anti-reflective coating layers per side, plus a waterproof, oil-resistant NANO top layer that resists stains and fingerprints.
• SR Tempered Glass: Uses Irix's SR (Super Resistant) tempered-glass process for added scratch and damage resistance.
• Frame: Low-profile aluminum alloy frame designed for a thin, glare-resistant edge.
• Filter Size: Sized for 77mm lens threads.
