1. True Color Ultra-Low Reflectivity CPL (Circular Polarizer)

Light Transmission: ~45%

Reflectivity: Ultra-low at 0.1% to 0.2%

Color Accuracy: Removes the yellowish/warm color cast common in standard polarizers

Frame Thickness: Ultra-slim CNC-machined frame to prevent vignetting

2. Variable ND + CPL 2-in-1 Filter

Light Reduction: 2 to 6 stops (ND4 to ND64) or 1 to 5 stops depending on the specific variation

Design: Combines an adjustable neutral density filter and a circular polarizer in one housing

Artifact Control: Self-locking gear frame or auxiliary levers designed to completely eliminate the annoying "X" cross pattern at high densities

3. Black Mist (Diffusion) Filters

Strengths Available: Commonly found in 1/4 and 1/8

Transmittance: Typically 84% to 87% (for the 1/8)

Effect: Softens highlights, reduces skin blemishes, and produces a cinematic blooming effect around light sources

General Core Specs
