Sirui Astra T1.8 1.33x Full Frame Autofocus Anamorphic Cine Lenses 50mm - Innovative autofocus for anamorphic film production

Sirui Astra 50 mm T1.8 is a groundbreaking anamorphic cine lens that offers autofocus in full-frame film production. This lens combines a constant compression of 1.33x with a fast aperture, making it ideal for both professional and independent filmmakers. With its ability to create detailed and visually appealing images, it is perfect for dialogue scenes, documentaries, and compositions that require a natural width.

Outstanding image quality and anamorphic character

The constant compression of 1.33x provides a wider horizontal perspective than traditional spherical lenses with the same focal length. When the material is decompressed in post-production, it achieves a fantastic widescreen character of approximately 2.35:1 from 16:9 recordings. This lens also offers the elongated bokeh and visual depth typical of anamorphic optics, creating an atmospheric and engaging experience for the viewer.

Practical handling and autofocus features

With a maximum aperture of T1.8, this lens is excellent for controlling background blur and filming under varying lighting conditions. The STM-driven autofocus system and the practical AF/MF switch make it easy to switch between autofocus and manual focus, providing flexibility during shooting. Additionally, film-oriented focus and aperture controls allow for more precise handling when necessary, making it an excellent choice for independent productions.
