SIRUI announced the world’s first full-frame anamorphic lens, the ASTRA series. This 1.33x full-frame autofocus anamorphic cinema lens combines a fixed T1.8 aperture with a fast and reliable autofocus system.
Last year, SIRUI shocked the filmmaking community, sparking heated debate and garnering a lot of attention when they introduced their first Super 35 autofocus anamorphic lens. With the launch of the ASTRA series, the company is once again redefining the boundaries of affordable cinema lenses with a groundbreaking new product.
Designed for the modern creator, the ASTRA series is developed for independent filmmakers and producers who demand professional anamorphic imagery combined with the user-friendly operation essential for dynamic, improvisational shoots.

Cinematic Immersion: Full Frame 1.33x Anamorphic Widescreen
The ASTRA series is designed to combine full-frame compatibility with a fixed 1.33x anamorphic squeeze. When used with full-frame sensors, it enables a widescreen aspect ratio that delivers an overwhelmingly immersive experience, producing effects that are iconic of premium filmmaking, such as horizontal lens flares and distinctive elliptical bokeh. Anamorphic image expression is no longer the preserve of big-budget sets. ASTRA puts this expressive power directly within the reach of independent filmmakers and content creators.

T1.8: A revolution in low-light performance and portability
The T1.8 maximum aperture represents a breakthrough in full-frame anamorphic lenses, but SIRUI’s true value lies in its incredibly compact design. With a lightweight and small footprint of just 600-700g, the ASTRA series breaks the common belief that high-speed T1.8 anamorphic lenses are necessarily heavy and bulky.

This combination enables creators to excel in challenging low-light environments, capturing clear, usable footage where other lenses struggle—all without the burden of heavy equipment. It also creates a shallow depth of field, easily separating the subject from the background, and produces smooth, distinctive anamorphic bokeh. The powerful combination of lightweight design and large aperture adds a powerful, dramatic cinematic quality to every frame, from intimate portraits to majestic landscapes.

Seamless control: advanced AF and MF system
Building on its pioneering track record in anamorphic autofocus, SIRUI has further evolved its AF technology. The AF system in ASTRA lenses delivers high speed, high precision, smooth, stable and fluid focusing, essential for a wide range of scenes, from unpredictable run-and-gun shooting to controlled portraits.
For users who prefer manual operation, the lens features an ingenious system that allows users to freely switch between AF and MF. The manual focus ring features precise focus distance scales, ensuring compatibility with follow focus and LiDAR systems, meeting the demands of professional filmmaking workflows.

Designed for creators: lightweight, consistent, and comprehensive
Understanding the needs of modern filmmakers, SIRUI designed the ASTRA series with portability and efficiency in mind. The three newly added focal lengths (50mm, 75mm, and 100mm) are all compact. All lenses feature a consistent 67mm filter thread and weigh just 600-700g. This consistency ensures high portability and allows for quick lens switching on gimbals or rigs without the need for readjustment.

Versatility and Support
To ensure wide compatibility, the ASTRA series is compatible with E-mount, Z-mount, and L-mount systems, covering all mainstream mirrorless platforms. In particular, SIRUI’s membership in the Leica L-Mount Alliance and official manufacturing authorization for L-Mount lenses highlights the company’s commitment to quality and professional standards.
Further enhancing creativity, two flare styles allow users to choose between the popular classic blue flare or a more neutral beam of light, giving filmmakers the flexibility to create a variety of visual expressions.
