Lens Overview — IRIX 11mm T4.3

The IRIX 11mm T4.3 is a prime cinema lens built for full-frame sensors, offering a wide-angle perspective at a fixed 11mm focal length. Designed for the Cinema/Video camera system, it carries a PL Mount interface — one of the most widely adopted standards in professional cine production — making it a practical choice for cinematographers working with high-end cinema cameras. The lens operates at a maximum aperture of T4.3, a measured T-stop rating that reflects real-world light transmission rather than a theoretical f-stop value, giving cinematographers accurate exposure consistency across a matched lens set.

Focus is entirely manual, which aligns with standard cinema workflow practices where focus pullers operate dedicated follow focus systems. With no image stabilization, the lens is intended for use on rigged cinema setups where stabilization is handled externally. Weighing in at 1,105g, it sits on the heavier side but is proportionate to its full-frame cinema construction.

The 86mm filter thread accommodates standard front-mounted filtration. As a prime lens in the wide-angle focal length range, the IRIX 11mm T4.3 on PL Mount is a purposeful tool for wide establishing shots, environmental storytelling, and immersive visual perspectives in professional cine production.
