Irix Edge MMS CPL + Black Mist 1/2

Polarization and diffusion in a single optical element. No optical compromise.

A CPL and Black Mist 1/2 combined in one filter is a product you won’t find in competing lineups. The Irix MMS CPL + Black Mist 1/2 lets you cut reflections, deepen color saturation, and add organic highlight diffusion to your shots — without stacking two separate filters and without any measurable loss in sharpness. MTF testing (iQ-Analyzer) returned 93% center-frame sharpness with the filter versus 91% without it. This isn’t a compromise. It’s a tool that optically holds its own — and then some.

Designed with filmmakers and photographers in mind

Irix MMS CPL + Black Mist 1/2 is designed for photographers and filmmakers who want to combine precise light control with a refined cinematic look. It brings together two highly desirable effects in one filter: the reflection reduction and color enhancement of a CPL, and the subtle highlight bloom of a Black Mist 1/2. The result is a richer, more dimensional image with cleaner reflections, deeper color, and a softer, more atmospheric rendering of light.

This is the ideal choice for creators who want more than a single-purpose filter. The CPL element helps cut distracting glare and improve color separation, while the Black Mist effect gently softens highlights and gives bright areas a smoother, more cinematic roll-off. Together, they create an image that feels more polished, more immersive, and more emotionally engaging — without losing its natural detail or overall clarity.

Built specifically for the Magnetic Mount System, this filter is made for lenses equipped with the MMS mount, allowing for a faster and more intuitive workflow on set. When every second counts, quick mounting and filter changes become a real advantage. The slim 3.5 mm frame also supports the compact, professional character of the design.

Key Benefits

• Two optical effects, one glass surface Most filmmakers and photographers who want both polarization and diffusion have to stack two filters — adding thickness, increasing vignetting risk, and complicating the workflow. The Irix MMS CPL + Black Mist 1/2 eliminates that problem. Both effects are integrated into a single optical element with a frame thickness of just 3.5 mm (4.87 mm total).

• CPL polarization: reflection control and color depth The rotatable CPL layer provides precise control over reflections from glass, water, and glossy surfaces. The result is deeper color saturation, better tonal separation, and improved scene clarity — particularly visible in outdoor, architectural, and water-based scenes.

• Black Mist 1/2 diffusion: softened highlights, organic roll-off The 1/2 intensity is the most versatile Black Mist setting — strong enough to add a cinematic highlight character (halation around light sources, smoother tonal transitions), yet subtle enough to preserve critical detail. Unlike the Tiffen Black Pro-Mist, which uses black particles embedded in glass, Irix Edge applies multi-layer optical coatings for a more controlled diffusion effect while maintaining color neutrality.

• Verified optical quality — MTF and Siemens star testing (Canon EOS 5DS R, 50 MP) MTF analysis (iQ-Analyzer): 93% center-frame with the filter vs. 91% without — tested on a 50-megapixel sensor where every optical flaw is exposed. This indicates zero image degradation — and the multi-layer anti-reflective coatings may even support contrast. Siemens star analysis confirmed no measurable loss of resolution, preserved image symmetry, and comparable sharpness across the frame. Vignetting (Imatest): with filter sides -1.01 to -1.14 EV, corners -3.39 EV (corner mean -2.66 EV); without filter sides -1.1 to -1.21 EV, corners -3.71 EV (corner mean -2.94 EV) — no negative vignetting impact.

• Studio comparison: CPL + Black Mist 1/2 vs. standalone Black Mist 1/2 The lab report includes a three-way studio comparison of the same scene: no filter, CPL + Black Mist 1/2, and standalone Black Mist 1/2. The key difference: the CPL + Black Mist shot preserves the characteristic highlight diffusion while simultaneously eliminating unwanted reflections via the CPL layer. The standalone Black Mist 1/2 diffuses light but leaves reflections untouched. This is a practical demonstration of the combo filter’s real-world value.

Protective coatings: hydrophobic + scratch-resistant

Dual-sided NANO coating repels water, grease, and contaminants. The scratch-resistant surface improves durability during intensive use, frequent cleaning, and transport in a camera bag or production kit.

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.

Magnetic mount–smooth, fast and secure workflow

The threadless MMS magnetic mount lets you attach and remove the filter one-handed, without looking away from the monitor. During fast configuration changes on set — switching from CPL + Black Mist to a clean ND, for example — you save real seconds that matter on a professional production. The system is compatible with Irix Cine lenses: 15mm T2.6, 30mm T1.5, 45mm T1.5, 65mm T1.5 and 150mm T3.0 Macro (excluding the 11mm T4.3 and 21mm T1.5).

Ultra-thin filter profile

As you already know, the Irix Edge Magnetic Mount System filters have super-thin filter profiles. The total thickness of the filter is 5mm, combined with the possibility of stacking, will allow you to save a significant amount of space for other useful equipment.
