Sirui IronStar 35mm T1.9 1.5x Anamorphic Full Frame Cine Lense PL/EF

Sirui IronStar 35mm T1.9 1.5x Anamorphic Full Frame Cine Lens

The Sirui IronStar 35mm T1.9 1.5x Anamorphic Full Frame Cine Lens (PL/EF) combines full frame optics, 1.5x anamorphic compression and a bright T1.9 aperture to deliver cinematic image quality with a powerful sense of presence. With its wide angle of view, unique flare characteristics and robust build quality, this lens is ideal for filmmakers looking to create visually engaging stories.

1.5x anamorphic compression for cinema feel

With a constant 1.5x squeeze ratio, IronStar 35mm offers a cinematic 2.25:1 (3:2) or 2.66:1 (16:9) image. The wide angle of view, combined with authentic oval bokeh and horizontal compression, makes it perfect for grand scenes, narrative films and visually intense environments.

Wide-angle full-frame coverage

The horizontal angle of view is equivalent to 23mm at full frame, making the 35mm version optimal for landscapes, cityscapes and atmospheric scenes. It captures both environment and movement without losing subject presence or perspective.

T1.9 aperture - fast and accurate

The fast T1.9 aperture delivers sharp low-light images and smooth, cinematic bokeh. Vertical blur transitions smoothly to horizontal compression, creating imagery with depth, character and emotional expression.

Professional optics with 20 elements in 16 groups

The Sirui IronStar 35mm features 20 elements in 16 groups including ED, HRI, aspherical and cylindrical lenses. The combination ensures high resolution, minimal aberration and natural color reproduction. Focus breathing is virtually eliminated, resulting in smooth shots when changing focus - a feature that professional filmmakers appreciate.

Two unique flare styles

Choose between Classic Blue Flare for science fiction and action, or Neutral Flare for natural and emotional scenes. Both versions create a genuine cinematic feel depending on the lighting and tone of the scene.

Switch between PL and EF mount

The lens comes with both PL and EF mount. Thanks to the included tool kit, you can quickly switch mounts without spacers or workshop adjustment. Back focus adjustment also allows you to fine-tune the flange distance for maximum precision.

Robust and rig-friendly design

The IronStar 35mm weighs around 1 kg and has a front diameter of 95 mm - perfect for matte box and gimbal. It features a 270° focus ring with dual marking (meter/foot) and a metal construction that ensures durability, color matching and consistency across the IronStar range.
