Product description

The Sirui IronStar 100mm is a full-frame anamorphic cine lens with a T2.8 aperture and a 1.5x squeeze. Its horizontal field of view matches a 66mm lens on full frame – 0.5x macro from 0.3 m for food, jewellery and product commercials. This neutral flare version has a native PL mount and comes with an interchangeable EF mount module and tools. The filter thread is 92mm.

100mm anamorphic with a 1.5x squeeze

All IronStar focal lengths share the same look, colour rendering and gear positions. The 46mm image circle covers the full-frame sensor, so the widescreen image comes without vignetting or cropping.

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.

Focus from 0.3 m

0.5x macro captures fine detail while keeping the anamorphic character of the image.

16 aperture blades

Aperture from T2.8 to T16 for shallow depth of field even in low light.

19 elements in 15 groups

Optics with 5 cylindrical elements and an aspherical element.

Weight 1,109 g

With the PL mount and without cap; 1,085 g with the EF module.

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. The PL mount can be set in four positions 90° apart, so the lens also works for vertical shooting.

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.
