Modern filmmakers want more than just sharp images—they want cinematic depth, immersive widescreen shots, and a workflow fast enough for real productions. Traditionally, anamorphic filming 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 series, the SIRUI Astra line combines a cinematic 1.33x squeeze factor, a bright T1.8 aperture, a lightweight design, and modern autofocus technology in a compact system for today’s creatives. Whether feature films, commercials, documentaries, or online content—the Astra series delivers professional cinematic results with a significantly more flexible workflow.
The world’s first full-frame autofocus anamorphic lens for faster solo productions
The SIRUI Astra series brings something filmmakers have wanted for years: a true full-frame autofocus anamorphic system. Unlike traditional anamorphic lenses that rely entirely on manual focus, Astra integrates fast and reliable autofocus into cinematic filming—without losing the classic anamorphic look.
This groundbreaking design makes anamorphic filming much more practical for solo creators, small teams, handheld productions, and fast content workflows. Instead of constantly having to manually control focus during action-packed scenes, filmmakers can focus more on composition, storytelling, and camera movement.
The Astra series combines:
-
T1.8 1.33x full-frame anamorphic design
-
Fast and precise autofocus
-
Cinematic widescreen presentation
-
Lightweight design for modern productions
-
Reliable low-light performance
With its constant 1.33x squeeze factor, the lens creates immersive cinematic compositions while preserving a natural field of view. The result is a professional film aesthetic with elegant oval bokeh, cinematic subject separation, and enhanced visual storytelling.
The bright T1.8 aperture also makes the Astra series an excellent choice for low-light filmmaking. From nighttime outdoor shots to dimly lit interiors, filmmakers can maintain high image quality while achieving shallow depth of field and smooth background blur.
For creatives who want to use the visual language of cinema without the limitations of traditional manual anamorphic setups, the SIRUI Astra Anamorphic Lens represents a significant advancement.
Blue flares or neutral flares — Choose your cinematic style
One of the most distinctive features of anamorphic cinematography is lens flares. The SIRUI Astra series gives filmmakers the option to choose between two different 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 films. Strong horizontal blue light streaks create a dramatic and stylized image, especially suited for music videos, futuristic scenes, commercials, and high-contrast lighting situations.
For filmmakers who prefer a cleaner and more natural image, the Neutral Flare version offers a subtler cinematic look. It preserves the immersive anamorphic character while reducing overly stylized flare effects, making it ideal for documentaries, narrative films, interviews, and commercial productions.
By choosing between Blue Flare and Neutral Flare, creatives can tailor the lens to different storytelling moods and visual identities.
Seamless AF/MF switching for professional cinema workflows
Although autofocus is one of the biggest innovations of the Astra series, SIRUI also understands the importance of manual control in professional filmmaking.
The lenses feature seamless AF/MF switching, allowing creatives to instantly switch between autofocus and precise manual focusing depending on the shooting situation. This flexibility is especially valuable in controlled cinematic productions where precise focus pulling is crucial.
The manual focus ring has clear focus distance markings for greater precision and compatibility with professional follow-focus systems. Whether mounted on a handheld rig, tripod, shoulder rig, or gimbal — Astra lenses integrate seamlessly into professional cinema workflows.
Additional cinema-oriented design features improve production efficiency, including:
-
Consistent gear positions across the entire lens series
-
Uniform 67mm filter thread
-
Compact and lightweight design
-
Smooth focus ring
-
Fast lens changes during production
For filmmakers who want to combine speed and cinematic precision, the Astra series offers a workflow that is much closer to dedicated cinema lenses than classic hybrid photo lenses.
A complete anamorphic lens set with 50 mm, 75 mm, and 100 mm
The SIRUI Astra series was developed as a complete cinematic lens ecosystem. The focal lengths 50 mm, 75 mm, and 100 mm offer filmmakers versatile visual options for different storytelling scenarios while maintaining a consistent look and identical handling across the entire series.
Since the lenses have similar dimensions, gear positions, and operating concepts, switching between focal lengths during a production is quick and efficient.
50 mm — Natural cinematic storytelling
The SIRUI Astra 50mm T1.8 1.33x full-frame autofocus anamorphic lens offers one of the most versatile cinematic perspectives in the series. Its natural field of view is ideal for:
-
Interviews
-
Narrative film productions
-
Commercial films
-
Environmental portraits
-
Handheld storytelling
The 50 mm focal length creates a balanced relationship between subject isolation and environmental depiction, producing immersive cinematic compositions without excessive compression.
75 mm — Emotional close-ups and strong subject separation
The 75 mm anamorphic lens produces stronger cinematic compression and improved background separation, making it particularly suited for emotional storytelling and dramatic close-ups.
It is especially suitable for:
-
Emotional character shots
-
Tighter compositions
-
Dialogue scenes
-
Cinematic portraits
-
Medium close-up framing
The stronger compression creates a more intimate visual connection between the audience and the subject while preserving the characteristic anamorphic aesthetic.
100 mm — Tele-cinematic with strong depth effect and compression
The 100 mm anamorphic lens delivers powerful telephoto compression and dramatic cinematic depth, making it ideal for highly stylized visual storytelling.
This focal length is especially convincing for:
-
Close-up portraits
-
Shots over longer distances
-
Dramatic cinematic compression
-
Isolated subject shots
-
High-quality commercial visuals
The stronger compression creates layered cinematic depth and visually impressive background separation, enhancing the emotional impact within an image.
Together, the Astra lenses with 50 mm, 75 mm, and 100 mm form a professional full-frame anamorphic toolkit for a wide range of cinematic production styles.
