The Irix Cine 21mm T1.5 L Mount lens pairs a wide 21 mm field of view with fast T1.5 transmission for full-frame cinema work. Its 43.3 mm image circle supports expansive compositions, interiors, events, and close perspective-driven shots while keeping subject proportions controlled. The imperial distance scale provides focus markings in feet for crews that work with that standard.
Wide Full Frame Optics
Built for 43.3 mm full frame coverage, the lens uses 11 rounded iris blades to produce smooth out-of-focus rendering. Very low focus breathing helps framing stay stable during focus changes, while low distortion supports natural-looking wide compositions. The supplied product information also identifies the optics as 8K-ready for high-resolution capture workflows.
Cinema Focus and Iris Control
Manual focus is supported by a 180-degree focus ring rotation and standard 0.8 M gearing with 117 teeth. The aperture ring rotates 75 degrees and uses matching 0.8 M gearing with 110 teeth. Internal focusing and consistent cine-style gear placement help the lens integrate into follow focus and rig-based workflows without changing the external lens length during focusing.
Weather Sealed Working Design
Four rubber O-rings provide weather sealing for work around dust and moisture. Laser-engraved, UV-reactive markings remain easier to read in dim production environments. A standardized 95 mm front diameter supports cinema accessories, while the detachable lens support foot helps reduce strain on the camera mount when the lens is used with follow focus equipment.
