Cinematic Full-Frame Anamorphic Capture

Bring a widescreen, cinematic look to your productions with the Sirui IronStar 45mm T1.9 Anamorphic 1.5x Lens. Designed for full-frame cameras, this lens delivers a classic anamorphic aesthetic with rich subject separation, oval bokeh, and natural streak flares. Its fast T1.9 maximum aperture provides outstanding low-light performance while maintaining shallow depth of field for dramatic, filmic visuals.

Signature Anamorphic Look

1.5x Squeeze Ratio – Creates the signature anamorphic widescreen format.
Cinematic Bokeh – Produces oval-shaped out-of-focus highlights for a true anamorphic character.
Natural Flares – Neutral streak flares emerge when pointed at strong light sources.
Wide Perspective – Provides a 30mm horizontal field of view on full-frame sensors.

Flexible Mount Options

Each IronStar prime comes with both ARRI PL and Canon EF mounts, allowing compatibility with a broad range of cinema cameras, mirrorless systems, and DSLRs. This flexibility makes it easy to adapt your lens kit as your camera setup evolves.

Built for Professional Production

The IronStar 45mm is built with a 95mm front diameter for matte box compatibility and features 0.8 MOD focus and iris gears for seamless integration with follow focus systems and lens control rigs. Its 270° focus rotation ensures precise, repeatable focus pulls, ideal for demanding narrative and commercial work.
