Irix Cine 11mm T4.3 Full-Frame Cinema Lens
The Irix Cine 11mm T4.3 covers full frame with a 117 degree horizontal field of view and no fisheye curvature, which is why it turns up on real estate and architectural shoots where the room has to look open and the verticals have to stay vertical. Distortion is held low by an internally focusing design, so the barrel does not change length and the front element does not rotate as focus is pulled. Weather sealing runs to four rubber o-rings, three on the PL version.
It carries the same 95 mm front diameter, 0.8 mod focus and iris gears and 1/4 in lens support foot as the rest of the Irix Cine line, so it drops into an existing follow focus and matte box rig without rebalancing. The bulbous front element rules out a screw-in filter thread; plan on a matte box for filtration. Markings are laser engraved and filled with UV reactive paint. All SKUs listed here are the imperial (feet) focus scale.
