Cinematic 45mm T1.5 Prime

The Irix 45mm T1.5 Cine Lens delivers professional image quality for Canon EF mount cinema cameras. Its 11-element optical design includes four high-refraction glass elements, an extra-low dispersion element and an aspherical lens. The construction achieves a distortion rate of .5 percent and covers a 51.4-degree field of view. The lens is built for Ultra HD 8K production workflows.

Verify EF Mount and Filter Thread

Confirm your camera body uses the Canon EF mount before ordering. The front housing measures 95mm in diameter and accepts 86mm screw-in filters. A magnetic mount secures the reversible hood and future Irix Cine accessories. The lens barrel includes rubber seals at critical points for weather resistance against rain and dust.

Manual Focus Build with Follow Focus Ready

This lens operates entirely via manual focus with a 180-degree rotation angle for precise, repeatable pulls. Focus and iris rings share the same height and rotation angle for streamlined operation. A unique rotating adaptive ring allows compatibility with any follow focus system. The T1.5 aperture uses 9 rounded blades for smooth background separation.

Questions about this item

What comes in the box with the Irix 45mm T1.5 Cine Lens and what must I buy separately?

The lens has a built-in 86mm filter thread and a magnetic mount for a reversible hood, so standard 86mm filters attach directly and the hood mounts magnetically; a follow-focus system is compatible but not included.

Which focal length and aperture version should I choose for 8K cinema work?

This model is a single 45mm T1.5 version designed for Ultra HD 8K cameras with a 51.4-degree field of view, so there are no alternative capacities to select.

What does the T1.5 rating mean when I use the lens on a real cinema camera?

T1.5 measures the true light transmission for consistent exposure across takes, while the f/1.5 aperture with nine rounded blades gives smooth bokeh and the optical design keeps distortion to 0.5%.
