Product description for Sirui IronStar T1.9 1.5x Anamorphic Full-Frame Cine Lens 75 mm Neutral Flare

IronStar 1.5x Full-Frame Anamorphic Cinema Lens Set

Bring the widescreen back to life with IronStar
The first set includes three lenses—35 mm, 45 mm, and 60 mm—for basic framing. Following the release of the 75 mm, 100 mm (macro), and 135 mm lenses to complete the system, the IronStar set now comprehensively supports both commercial and artistic film projects. The 100mm lens, with a minimum focusing distance of 0.3 m, overcomes the limitations of anamorphic close-ups and improves detail reproduction at close range. Identical gear positions and front diameters ensure consistent optical performance across the entire set.

Three new focal lengths
From medium to telephoto focal lengths—versatile for all subjects and widescreen shots!

75 mm T1.9

  • Natural storytelling
    Equivalent to 50 mm horizontally on full-frame. Human eye perspective, ideal for dialogue and storytelling. Balanced separation of subject and background.
  • Minimum focusing distance 0.8 m

Constant compression ratio of 1.5x
Compared to 1.33x, 1.5x offers a wider horizontal field of view, stronger background compression, and a more elliptical bokeh, which enhances the overall cinematic look and feel.

  • 3:2 mode → 2.25:1 widescreen format
  • 16:9 mode → 2.66:1 widescreen format
  • 16:9 output in 6:5 mode

*Effortlessly achieve a classic 2.4:1 widescreen aspect ratio with minimal cropping.

Support for vertical shooting
The PL mount, which rotates 360° in four directions, supports both horizontal and vertical shooting. When combined with a vertical monitor, it enables a professional on-set monitoring system that transcends traditional aspect ratio limitations and opens up a new form of cinematic vertical widescreen storytelling.

Large Image Circle
The IronStar series lens set features a 46mm image circle, ensuring full coverage of all full-frame sensors in mirrorless cameras. It produces a clear, vignette-free image and delivers a truly immersive cinematic experience.

Sharp and Even
The extremely fast T1.9 aperture ensures sharp performance in low-light conditions. The vertical bokeh is smooth, with sharp subjects and blurred backgrounds, effortlessly creating a shallow depth-of-field look rich in spatial depth and artistic tension.
*35/45/60/75 mm, maximum aperture T1.9

Cinematic Atmosphere
Features two flare styles—blue and natural flare—that enhance the anamorphic look with a cinematic aesthetic.

  • Neutral Flare
    Presents light in its natural form and is suitable for everyday shots, emotional commercials, natural and humanistic scenes, etc.

Outstanding optical performance
The IronStar series lenses feature 19 precision optical elements, including aspherical and cylindrical lenses, to reduce weight and produce sharp images with a subtle vintage glow – where modern technology meets classic cinematic aesthetics.


  • Aspherical Lens Precisely corrects spherical aberrations and chromatic aberrations at the edges, reduces weight, and improves image clarity.

  • Cylindrical Lens A precise optical design with multiple cylindrical elements helps prevent distortion, flare, and loss of sharpness.

Well-controlled focus breathing
Virtually zero focus breathing during focus shifts ensures image stability and consistency—essential for professional film production workflows.

Consistency on Set
The IronStar series lenses are designed for a consistent look, color temperature, and color tone, ensuring a unified visual style throughout the creative process.

Wide Compatibility

  • Filter thread: Ф92 mm/3.6 inches,
  • CPL and VND filters included in the kit
  • Front diameter: Ф95 mm/3.7 inches, compatible with standard cinema-grade matte boxes

Identical gear position
Designed for quick lens changes, which simplifies the process of follow-focusing and accessory adjustments.

Compact and lightweight
The lightest model weighs 1085 g

1/4" threaded base
Improves mounting stability

Interchangeable PL/EF Mount Module
Each lens features a native PL mount and comes with an EF mount and the necessary tools. Users can effortlessly switch between mounts as needed, significantly improving the lens’s cost-effectiveness and versatility.

Innovative back focus adjustment
Simply turn the back focus adjustment ring instead of disassembling the mount or adding shims—for flexible and convenient operation.

Born for professional quality
This affordable anamorphic cine lens enables indie filmmakers, small teams, and commercial project groups to work with cinematic precision.

Free replacement within three years for non-human-caused damage (with valid proof of purchase). Lifetime paid repair service for human-caused damage (e.g., drops, water, modifications).
