The Sirui Astra Series 50mm T1.8 1.33x Full-Frame Anamorphic Lens for Nikon Z-Mount is a professional cinema lens designed to deliver the distinctive widescreen look and cinematic character of anamorphic filmmaking. Engineered for full-frame cameras, it produces a 2.35:1 aspect ratio when de-squeezed from a standard 16:9 sensor, creating immersive visual storytelling with authentic anamorphic aesthetics.
With a bright T1.8 aperture, this lens offers excellent low-light performance and shallow depth of field for strong subject separation. The 1.33x squeeze factor generates signature oval bokeh and striking blue lens flares, adding the classic cinematic style favored in feature films and high-end productions.
The 50mm focal length provides a natural perspective that is highly versatile for narrative scenes, interviews, portraits, and commercial work. Its precise manual focus and geared aperture rings are optimized for follow-focus systems, enabling smooth and accurate adjustments during shooting.
Built with robust all-metal construction, the Astra Series lens is designed for demanding professional workflows. It combines exceptional optical performance with the creative advantages of anamorphic cinematography, making it an outstanding choice for filmmakers using Nikon Z mirrorless cameras.
