Sirui 50mm T2.9 Full Frame 1.6x Anamorphic Lens
The Sirui 50mm T2.9 Full Frame 1.6x Anamorphic Lens is a professional cine prime crafted for filmmakers who want the cinematic widescreen look without sacrificing optical precision. Designed for full-frame cameras, this lens offers a 1.6x anamorphic squeeze, fast T2.9 aperture, and a robust cine housing — making it a reliable tool for narrative films, commercials, and creative storytelling projects.
With its 50mm focal length, this lens sits in the perfect sweet spot between wide and telephoto perspectives. It delivers a natural field of view ideal for dialogue scenes, character-driven storytelling, and portrait cinematography. Combined with its anamorphic design, it produces epic widescreen visuals with oval bokeh and signature horizontal flares.
1.6x Anamorphic Squeeze for Cinematic Aspect Ratio
The Sirui 50mm Anamorphic Lens incorporates a 1.6x anamorphic squeeze factor, which transforms a standard 16:9 sensor into an ultra-wide 2.8:1 aspect ratio once de-squeezed. This creates Cinemascope-style imagery reminiscent of classic Hollywood films.
Unlike cropping in post-production, the anamorphic squeeze preserves full sensor resolution, ensuring that every frame maintains detail and sharpness. This allows filmmakers to achieve a true cinematic look straight out of the camera.
Signature Anamorphic Visuals
The Sirui 50mm T2.9 Anamorphic Cine Prime captures the characteristic anamorphic aesthetics that filmmakers love, including:
-
Oval-shaped bokeh that adds emotional depth to portraits and close-ups.
-
Cinematic blue horizontal lens flares that enhance storytelling impact.
-
Wide field of view with natural perspective compression.
This makes the lens perfect for music videos, feature films, advertising campaigns, and high-end creative projects.
Bright T2.9 Aperture
The fast T2.9 maximum aperture ensures excellent low-light performance and gives filmmakers the ability to create shallow depth of field effects with creamy, cinematic background blur.
This aperture flexibility makes it suitable for studio productions, outdoor shoots, and run-and-gun filmmaking where lighting conditions vary.
Full Frame Compatibility
The Sirui 50mm T2.9 Lens offers full-frame coverage, supporting modern large-format cinema cameras with an image circle up to 44mm. Whether shooting in 4K, 6K, or 8K, it delivers sharpness across the frame with minimal distortion.
Its versatility makes it future-ready for both digital cinema and professional video workflows.
Professional Cine Housing
Designed for professional use, the Sirui 50mm Cine Lens features a durable all-metal construction. It includes 0.8 pitch gears on both the focus and aperture rings, ensuring compatibility with industry-standard follow focus systems.
The lens also has a 270° focus throw, giving cinematographers precise control over focus pulls. Its 95mm front diameter supports matte boxes and cinema filters, making it an easy fit into professional rigs.
Engraved, luminous markings ensure readability during low-light shoots, a valuable feature on demanding sets.
