Nikon Z – native mount

This version uses a nativeNikon Z mountfor cameras built around the Nikon Z bayonet. It is designed directly for the Z system and does not rely on a Nikon F version.

Metric – focus scale in metres

TheMetricversion uses a focusing distance scale marked inmetres. Optical and mechanical performance are the same as the Imperial version; only the distance units on the scale differ.

Full Frame coverage and 8K-ready optics

The Irix Cine 11mm T4.3 is designed for Full Frame sensors. Its43.3 mm image circlecovers the Full Frame format, while the optical system is prepared for high-resolution capture including Ultra HD 8K. The actual field of view depends on the camera sensor format.

11 mm and up to 123° of cinematic perspective

In a2.39:1widescreen format, the horizontal field of view can reach approximately123°. The rectilinear design keeps the ultra-wide perspective without the characteristic curvature of a fisheye lens.

16 optical elements – designed for cinema

The optical system uses16 elementsincluding four HR elements, three ASP aspherical elements and two low-dispersion ED elements. It is optimized for high resolution, low aberrations and a consistent image character.

T4.3–T22 and 9 rounded iris blades

The iris operates smoothly fromT4.3 to T22and uses9 rounded blades. Its mechanical, clickless control is designed for precise exposure changes during filming.

Fully manual cine operation

Focus and iris are controlled directly through the mechanical lens rings. The design does not rely on electronic camera-body control, providing a predictable and repeatable workflow on set.

Very low focus breathing

The optical design minimizes field-of-view changes while focusing. Focus pulls therefore look more natural and the framing remains more stable.

180° focus rotation and Mod 0.8 gears

The focus ring offers180° of rotationwhile the iris ring rotates by about75°. StandardMod 0.8gears integrate with both manual and motorized follow-focus systems.

Irix MMS – fast magnetic filter changes

The front of the lens uses theMagnetic Mount System – MMS. It allows compatible magneticIrix Edge MMSfilters and other Irix accessories to be attached quickly without threading them onto the lens.

95 mm front diameter – a cinema standard

The lens has a95 mm front diameter. The Irix Cine 11mm has no conventional front filter thread; compatible filters mount through MMS, while the 95 mm front supports integration with common cine accessories.

Weather-sealed construction for location work

An aluminium-magnesium alloy body and seals at key points help protect the mechanics from dust, moisture and splashes. Laser-engraved UV-reactive markings remain easier to read in low-light conditions.
