Lens Overview — IRIX 15mm

The IRIX 15mm Cinema Lens in PL Mount is a prime wide-angle cine lens designed for full-frame cinema camera systems. Built around a fixed 15mm focal length, it covers a full-frame image circle and pairs that coverage with a maximum aperture of T2.6, offering solid light-gathering capability for wide-angle cinematic work. As a manual focus lens with no autofocus or image stabilization, it is purpose-built for the controlled, deliberate focus pulls that define professional cinema production.

The PL Mount makes it a natural fit for high-end cinema camera platforms that rely on the industry-standard PL bayonet system. At 1,100g, the lens has a substantial but manageable build weight appropriate for a cinema prime intended for rigged or shoulder-mounted setups. The 95mm filter thread size provides compatibility with large-format matte boxes and filter systems commonly used in professional production pipelines.

With a lens type classified as Cine and a camera system designation of Cinema/Video, every aspect of this lens is oriented toward the demands of narrative and documentary filmmaking rather than still photography. It is a focused, no-compromise tool for cinematographers who need a reliable wide-angle prime on a PL-mount body.

Description — IRIX 15mm

The IRIX 15mm Cinema Lens in PL Mount is a dedicated cinema prime built for professional video and film production. With a fixed 15mm focal length and a full-frame image circle, it is designed to serve wide-angle cinematography on large-format cinema platforms. The maximum aperture of T2.6 provides reliable light throughput for a lens in this focal length class, and the T-stop rating ensures consistent, measurable exposure across matched lens sets.

Weighing 1,100g, the lens is constructed with the heft expected of a professional cine prime. Focus is entirely manual, with no autofocus system, aligning with standard cinema production practices where a dedicated focus puller controls focus pulls with precision. There is no image stabilization, keeping the optical design clean and predictable.

The 95mm filter thread supports large professional filter systems and matte box rigs. Classified as a Cine-type lens within the Cinema/Video camera system category, this IRIX prime is a straightforward, production-ready wide-angle option for PL-mount cinema workflows.
