Irix Edge MMS CPL + Black Mist 1/2 SR Filter combines two highly desirable optical effects in a single filter: circular polarization and Black Mist 1/2 diffusion. It allows you to reduce reflections, enhance color saturation, and add a subtle cinematic glow to highlights without stacking two separate filters.

Polarization and diffusion in one filter

The Black Mist 1/2 layer gently diffuses light and lowers contrast in bright areas without excessively affecting darker parts of the image. This creates a soft halo around light sources such as lamps, spotlights, or the sun, giving footage and photos a more atmospheric, cinematic character. The effect is especially appreciated in film production and portrait photography, where it can also help soften skin imperfections and harsh light.

The integrated CPL polarizing filter effectively reduces reflections from non-metallic surfaces such as water, glass, leaves, or painted objects. It improves scene clarity, enhances color saturation, and helps achieve deeper blue skies. The level of polarization can be smoothly adjusted by rotating the filter in its mount.

Together, these two effects allow creators to achieve a distinctive look with softer highlights, reduced glare, and naturally rendered colors, while keeping the workflow simpler and more compact than using multiple separate filters.

Designed for fast professional workflow

Irix Edge Magnetic Mount System (MMS) filters were designed for Irix Cine lenses. The magnetic, threadless mounting system makes installation and replacement quick, secure, and convenient, which significantly improves workflow on set. The flat-profile construction also makes the filter easier to handle and clean.

High optical quality and durable construction

The filter is made of high-quality optical glass with multi-layer anti-reflective coatings to maintain sharpness, contrast, and faithful color reproduction. Super Resistant (SR) tempered glass technology increases durability and resistance to mechanical damage, making the filter suitable for demanding shooting conditions. The protective NANO coating additionally repels water, grease, and contaminants while improving scratch resistance.

Verified by lab tests

Laboratory image quality analysis confirmed that the Irix MMS CPL + Black Mist 1/2 does not degrade optical performance in any measurable way. MTF testing (iQ-Analyzer) returned 93% center-frame sharpness with the filter vs. 91% without — confirming that sharpness and contrast remain at or above the reference level. Siemens star analysis showed no loss in resolution or image symmetry. Vignetting measurements (Imatest) confirmed no additional EV drop at the edges or corners. Lab documentation also verified hydrophobic coating and scratch resistance.

One glass element. Two effects. Full control over reflections, color, and highlight character. Irix MMS CPL + Black Mist 1/2 — the filter you don’t need to stack.

Expandable filter system

MMS filters are designed to be freely combined with one another, allowing you to build filter sets tailored to different scenes and production needs.

Compatible with Irix Matte Box IQ

The filter can also be used as part of a broader professional setup and is compatible with the Irix Matte Box IQ system.
