  • Type

    Standard

    The visual they offer is very close to the human eye and is often called "normal". They provide a natural result with minimal distortions and their focal distance is usually 40-55mm in full frame, 25-40mm in crop frame, and 80-100mm in medium format.

  • Mount

    The type of mount that the camera body must have in order for the lens to be fully functional when attached to it.

    2. Some lenses can be used with older mounts from the same manufacturer, sacrificing certain functions (e.g. autofocus), or even with mounts from other manufacturers using an adapter.

  • Sensor Type

    Full Frame

    Photographic lenses designed for use on full frame sensor cameras. A full frame lens can also be used on a crop frame sensor camera, but with its focal length adjusted according to the corresponding crop factor.

    For example, a full frame lens with a focal length of 50mm (standard) on a camera body with a crop factor of 1.6 will function with a perspective as if it were an 80mm lens (telephoto).

    The reverse does not work as the optics of a crop frame lens are not sufficient to cover an entire full frame sensor, resulting in the edges of the frame being black (severe vignetting).

Description

The Sirui Astra 100mm T1.8 1.33x is a groundbreaking full-frame anamorphic cine lens for Sony E-mount cameras. It is a world-first innovation, combining classic anamorphic aesthetics with a modern autofocus system. Its constant 1.33x squeeze ratio instantly transforms 16:9 footage into a 2.35:1 widescreen cinematic aspect ratio without cropping. The ultra-fast T1.8 aperture delivers impressive subject separation, oval bokeh, and crisp images in low light. The Neutral Flare version produces subtle, natural-toned flares, enabling solo creators to capture authentic cinematic visuals.

Innovative Autofocus in a Full-Frame Anamorphic Lens

The Sirui Astra is the first full-frame anamorphic cinema lens with autofocus.
While traditional anamorphic lenses require manual focusing and a large crew, this lens simplifies the process.
The AF system delivers a fast and highly precise response for every cinematic shot.
It completely eliminates the need for external follow-focus mechanisms, reducing the overall weight of the rig.
It allows solo operators or small production teams to achieve professional results with ease.
Greater workflow efficiency speeds up shoots without compromising image quality.

Constant 1.33x Squeeze and Cinematic 2.35:1 Aspect Ratio

It features a constant 1.33x squeeze ratio throughout the entire focus range.
Since most modern mirrorless cameras record in 16:9, the lens automatically produces a 2.35:1 frame.
The classic widescreen look is achieved without cropping and with no loss of resolution.
It uses every available pixel on the full-frame sensor for maximum sharpness and detail.
This optical squeeze delivers a truly immersive viewing experience with a wide visual horizon.
It brings the authentic feel of traditional cinema directly to digital productions.

Bright T1.8 Cinema Aperture for Low-Light Conditions

The ultra-fast T1.8 cinema aperture ensures outstanding light gathering.
It enables comfortable night shooting and work in low-light scenes without unwanted noise.
It produces an especially shallow depth of field, naturally separating the subject from its surroundings.
It effortlessly directs the viewer’s attention to the main subjects and details of the action.
It maintains exceptional sharpness and tonal balance even at the aperture’s widest setting.
It lends rich texture, atmosphere, and cinematic depth in any lighting conditions.

Classic Oval Bokeh and Natural Neutral Flare

The anamorphic design produces the distinctive oval bokeh in out-of-focus light sources.
The vertical expansion of the background creates a unique sense of space and cinematic dimensionality.
This version features Neutral Flare technology.
It creates subtle backlight reflections that adapt to the color tone of natural light.
It avoids excessive color casts, preserving a more realistic and elegant cinematic look.
It creates a distinctive anamorphic identity that elevates the artistic value of the image.

100mm Telephoto Lens, Close-Ups, and Sony E Mount

The 100mm focal length offers ideal perspective compression for expressive portraits.
It delivers excellent close-up performance, bringing out facial details.
Designed for full-frame sensors with a Sony E-mount.
Despite its advanced optical elements, it retains a compact design that makes it easy to carry.
It perfectly complements the Astra series (50mm, 75mm, 100mm) as the go-to telephoto lens for capturing details.
An essential creative tool for filmmakers seeking intense emotion and focus.
