Irix Cine 11mm T4.3 Sony E-Mount Cinema Prime Lens (Imperial)

On a cramped interior set or a windswept exterior, the Irix Cine 11mm T4.3 gives cinematographers an ultra-wide perspective with full-frame coverage. Its manual focus and aperture rings are engineered for smooth, repeatable pulls, while the 0.8 MOD gears slot straight into standard follow-focus rigs. The lens body is machined from aluminum-magnesium alloy and sealed against dust and moisture, so it holds up to demanding production schedules.
