SIRUI IronStar Series – Anamorphic Cinematic Lenses

The SIRUI IronStar series is here to redefine what’s possible for filmmakers who crave cinematic character without breaking the bank. Engineered for full-frame sensors, these lenses deliver the signature widescreen look, creamy oval bokeh, and iconic flare that once belonged only to ultra-high-end cinema glass — now accessible to every creator.

Full-Frame 1.5× Anamorphic Power

With a 1.5× squeeze ratio, IronStar lenses unlock that immersive 2.25:1 aspect ratio on full-frame cameras, expanding your horizontal field of view while maintaining stunning image sharpness. This means you get the “cinemascope” aesthetic — stretched perspective, natural separation, and emotional depth — without the heavy cropping or post-workflow hassles of traditional 2× systems.

The series debuts with 35 mm, 45 mm, and 60 mm T1.9 focal lengths, each covering a full 46 mm image circle. The fast T1.9 aperture gives you excellent low-light performance and a beautifully shallow depth of field — perfect for narrative, commercial, or music-video work.

Designed for Creative Choice

IronStar comes in two distinctive flare options:

• Blue Flare – that classic sci-fi glow that cuts through urban nights, metallic reflections, and neon palettes.
• Neutral Flare – balanced and realistic, ideal for natural skin tones, daylight exteriors, and storytelling that favors subtlety.

Whichever you choose, the flares feel organic — never overpowering — while the 14-blade aperture ensures smooth, oval bokeh that enhances emotion in every frame.

Built Like True Cinema Glass

The IronStar lenses are all-metal, cine-built tools with geared focus and iris rings, standardized diameters, and precise focus throws for follow-focus systems. Interchangeable mounts (PL / EF) provide flexibility across camera ecosystems — from Sony and Canon to RED and ARRI.

Each lens is carefully balanced for gimbal, handheld, or shoulder-rig use, making it suitable for agile creators and professional DPs alike. The design consistency across focal lengths ensures seamless lens swaps and perfect visual matching during multi-camera shoots.

The Look That Inspires Storytelling

IronStar lenses produce images with personality — a blend of sharpness, warmth, and gentle compression that draws the viewer in. The 1.5× anamorphic ratio creates just the right amount of stretch without feeling exaggerated, while the color and contrast stay pleasingly cinematic.
This is the sweet spot for modern filmmakers: enough character to stand out, yet clean enough for commercial and feature production.

Built for the Future

SIRUI isn’t stopping with the first three focal lengths — 75 mm, 100 mm, and 135 mm are already in development, ensuring the IronStar family grows into a complete professional kit. That means users who start today can build toward a full system tomorrow, all with consistent optical character and matched performance.
