Modern filmmakers want more than just sharp images — they want cinematic depth, immersive widescreen visuals, and a workflow fast enough for real-world productions. Traditionally, anamorphic filmmaking required fully manual lenses, large cinema rigs, and complicated focus pulling. The SIRUI Astra changes that.
As the world’s first full-frame autofocus anamorphic lens series, the SIRUI Astra lineup combines a cinematic 1.33x squeeze ratio, fast T1.8 aperture, lightweight construction, and modern autofocus technology into a compact system built for today’s creators. Whether you are shooting narrative films, commercials, documentaries, or online content, the Astra series delivers professional cinematic results with a much more flexible workflow.
The World’s First Full-Frame Autofocus Anamorphic Lens for Solo-Ready Faster Productions
The SIRUI Astra series introduces something filmmakers have wanted for years: a true full-frame autofocus anamorphic lens system. Unlike traditional anamorphic lenses that rely entirely on manual focus, Astra brings fast and reliable autofocus into cinematic filmmaking without sacrificing the classic anamorphic look.
This breakthrough design makes anamorphic shooting far more practical for solo creators, small crews, handheld productions, and fast-paced content creation workflows. Instead of constantly managing manual focus during movement-heavy scenes, filmmakers can focus more on composition, storytelling, and camera motion.
The Astra lineup combines:
-
T1.8 1.33x full-frame anamorphic lens design
-
Fast and accurate autofocus performance
-
Cinematic widescreen imaging
-
Lightweight portability for modern productions
-
Reliable low-light shooting capability
With its constant 1.33x squeeze ratio, the lens creates immersive cinematic framing while preserving a natural field of view. The result is a professional movie-style aesthetic with elegant oval bokeh, cinematic subject separation, and enhanced visual storytelling.
The fast T1.8 aperture also makes the Astra series an excellent low-light filmmaking tool. From night exteriors to dim interior scenes, filmmakers can maintain strong image quality while achieving shallow depth of field and smooth background blur.
For creators who want the visual language of cinema without the limitations of traditional manual anamorphic setups, the SIRUI Astra anamorphic lens represents a major step forward.
Blue Flare or Neutral Flare — Choose Your Cinematic Style
One of the most recognizable characteristics of anamorphic cinematography is lens flare. The SIRUI Astra series gives filmmakers the flexibility to choose between two distinct visual styles depending on the mood and tone of a project.
The blue flare version delivers the classic anamorphic sci-fi aesthetic often associated with blockbuster cinema. Strong horizontal blue streaks create a dramatic and stylized image that works especially well for music videos, futuristic scenes, commercials, and high-contrast lighting environments.
For filmmakers who prefer a cleaner and more natural image, the neutral flare version offers a more subtle cinematic rendering. It preserves the immersive anamorphic character while reducing overly stylized flare artifacts, making it ideal for documentaries, narrative storytelling, interviews, and commercial productions.
By offering both blue flare and neutral flare options, the Astra series allows creators to adapt the lens to different storytelling moods and visual identities.
Seamless AF/MF Switching for Professional Cinema Workflows
While autofocus is one of the Astra series’ biggest innovations, SIRUI also understands the importance of manual control in professional filmmaking.
The lenses feature seamless AF/MF switching, allowing creators to instantly transition between autofocus operation and precise manual focus control depending on the shooting situation. This flexibility is especially valuable during controlled cinematic productions where focus pulling accuracy is critical.
The manual focus ring includes clear focus distance markings for improved precision and compatibility with professional follow focus systems. Whether mounted on a handheld rig, tripod setup, shoulder rig, or gimbal configuration, the Astra lenses integrate smoothly into professional cinema workflows.
Additional cine-oriented design features help streamline production efficiency, including:
-
Unified gear positions across the lens lineup
-
Consistent 67mm filter thread size
-
Compact and lightweight construction
-
Smooth focus ring operation
-
Fast lens swaps during production
For filmmakers balancing speed and cinematic precision, the Astra series delivers a workflow that feels far closer to dedicated cinema lenses than traditional hybrid photo lenses.
A Complete 50mm, 75mm, and 100mm Anamorphic Lens Kit
The SIRUI Astra lineup is designed as a complete cinematic lens ecosystem. The 50mm, 75mm, and 100mm focal lengths provide filmmakers with versatile visual options for different storytelling scenarios while maintaining a consistent look and handling experience across the entire set.
Because the lenses share similar physical dimensions, gear placement, and handling characteristics, switching focal lengths during production is quick and efficient.
50mm — Natural Cinematic Storytelling
The SIRUI Astra 50mm T1.8 1.33x full-frame autofocus anamorphic cine lens offers one of the most versatile cinematic perspectives in the lineup. Its natural field of view makes it ideal for:
-
Interviews
-
Narrative filmmaking
-
Commercial production
-
Environmental portraits
-
Handheld storytelling
The 50mm focal length balances subject isolation and environmental context, creating immersive cinematic compositions without feeling overly compressed.
75mm — Emotional Close-Ups and Subject Separation
The 75mm anamorphic lens introduces stronger cinematic compression and enhanced background separation, making it especially effective for emotional storytelling and dramatic close-up work.
It performs particularly well for:
-
Emotional character shots
-
Tighter compositions
-
Dialogue scenes
-
Cinematic portraiture
-
Medium close-up framing
The added compression helps create a more intimate visual connection between the audience and the subject while maintaining the signature anamorphic aesthetic.
100mm — Telephoto Cinematic Depth and Compression
The 100mm anamorphic lens delivers powerful telephoto compression and dramatic cinematic depth, making it ideal for highly stylized visual storytelling.
This focal length excels in:
-
Close-up portrait photography
-
Long-distance framing
-
Dramatic cinematic compression
-
Isolated subject shots
-
High-end commercial visuals
The stronger compression effect creates layered cinematic depth and visually striking background separation that enhances emotional impact within a frame.
Together, the 50mm, 75mm, and 100mm Astra lenses form a professional full-frame anamorphic toolkit capable of handling a wide range of cinematic production styles.
