Irix Cine 11mm T4.3 L-mount Imperial Cinema Lens

On a cramped indie set, the Irix Cine 11mm T4.3 L-mount lens lets the cinematographer capture the entire scene without moving the camera. Its 126° angle of view on full-frame sensors pulls every detail into frame, from the actor's expression to the gritty texture of the alley wall. The imperial focus scale, marked in feet, matches the workflow of crews who still think in inches and yards. Built from aluminum-magnesium alloy, the lens shrugs off the bumps of a run-and-gun shoot, while three rubber seals keep dust and moisture out when the weather turns. The 180° focus rotation gives the focus puller room to work precisely, and the 0.8 mod gear rings drop straight into standard follow-focus systems. This is a lens for filmmakers who need a wide perspective without compromise.

Good to know

The Irix Cine 11mm T4.3 is part of Irix's cinema lens lineup, designed for full-frame L-mount cameras. Its imperial focus markings cater to crews accustomed to feet and inches, while the internal focusing mechanism prevents the lens from changing length during focus pulls, maintaining balance on gimbals and rigs. The 95mm front filter thread allows the use of standard cinema filters, and the 9-blade aperture produces pleasing bokeh when shooting wide open. With a close focus distance of just 0.27m, you can get remarkably close to your subject while still capturing the expansive background.
