Controlled light diffusion

Black Mist works by deliberately diffusing part of the light. Highlights become softer, contrast is gently reduced and bright practical lights develop a smooth glow. The optical effect is captured in-camera rather than being created only in post-production.

Black Mist 1/4 – effect strength

The 1/4 strength sits between the subtle 1/8 and the stronger 1/2. It gives clearly visible highlight diffusion and lower contrast while keeping the image readable, making it a versatile choice for portraits and filmmaking.

Portraits and people – softer tonal transitions

For portraits, 1/4 helps soften harsh tonal transitions and minor skin imperfections without completely removing texture. It is a useful choice for beauty, fashion, music videos and narrative work featuring people.

Night scenes and video – glow around light sources

Around street lamps, neon signs and other bright points, 1/4 creates a characteristic soft glow. It suits night city scenes, music videos and cinematic work where the diffusion should be noticeable but remain controlled.

MMS – Magnetic Mount System

All Irix Cine lenses (except 11 and 21 mm) have the Magnetic Mount System (MMS), which is compatible with Irix Edge MMS filters and the Irix MMS Lens Hood. Irix Edge magnetic filters have a unique, threadless design, making them extremely quick to replace. MMS filters can be stacked on top of each other, which not only allows you to connect them freely, but also saves a lot of space during storage.

18 anti-reflective coating layers on each side

High-quality optical glass is coated with18 anti-reflective layers on each side. These coatings help control unwanted reflections and maintain strong image quality alongside the creative diffusion effect.

SR – tempered glass for increased durability

SRtechnology uses reinforced tempered glass with increased resistance to mechanical damage, a practical benefit for outdoor work, travel and intensive filmmaking.

Nano coating – easier maintenance

ANanosurface treatment provides hydrophobic and oleophobic properties together with an antistatic top layer. It helps reduce water, greasy marks, fingerprints and dust while making cleaning easier.
