Sirui IronStar 45mm T1.9 1.5x FF Anamorphic Cine Lens (Neutral Flare)

1.5x instead of 1.33x

Compared with a 1.33x squeeze, 1.5x gives a wider horizontal view, stronger background compression and more oval bokeh. A 3:2 sensor yields a 2.25:1 image, 16:9 recording a 2.66:1 widescreen frame.

Neutral flare

Neutral flare presents light in its natural form – ideal for everyday shooting, emotional commercials, nature and documentary. The series is also available with classic blue flare.

46 mm image circle

The 46 mm image circle covers the entire 36 × 24 mm full-frame sensor of mirrorless and cinema cameras. The image is clean, with no vignetting and no need to crop.

Minimal focus breathing

The framing barely changes during focus pulls. The shot stays stable and consistent, as professional film production demands.

Interchangeable PL and EF mount

The lens has a native PL mount and comes with an EF mount module and dedicated tools, so you can match the mount to your camera. Back focus is fine-tuned with a rotating ring – no need to disassemble the mount or add shims.

270° focus throw

The focus ring has a 270° throw for precise focus pulls. Gears sit in the same position on every lens in the series, so follow focus and accessories stay put when you swap lenses. Scales are marked in metres and feet.

1/4″ threaded base

A metal base with a 1/4″ thread under the lens adds mounting stability on a support. The metallic finish keeps the whole series looking uniform.
