Sigma Aizu Prime 65mm T1.3 LF

Cinematic Large Format Prime

The Aizu Prime 65mm T1.3 LF is designed to deliver a refined cinematic portrait perspective combined with the exceptional brightness and optical consistency that define Sigma’s Aizu Prime lineup. As part of the world’s first large-format cinema lens family with a constant T1.3 aperture across all focal lengths, the lens establishes a new standard for cinematic portraiture and narrative filmmaking.

The 65mm focal length provides elegant spatial compression and natural subject separation while maintaining a highly cinematic field of view. This makes the lens particularly effective for emotional close-ups, dialogue scenes, commercial cinematography, beauty work, and dramatic storytelling applications.

Optically, the lens combines high-resolution sharpness with an organic rendering profile optimized for cinema production. Skin tones render naturally, highlights transition smoothly, and out-of-focus areas maintain refined softness without sacrificing overall image detail. The result is a cinematic image that balances technical precision with emotional depth.

The constant T1.3 aperture allows filmmakers to achieve exceptionally shallow depth of field and excellent low-light performance. Subjects separate naturally from the background while maintaining smooth and cinematic focus falloff. Focus breathing and distortion are carefully minimized to ensure stable framing during focus transitions and moving shots.

Mechanically, the lens features a professional cine-standard housing with full-metal construction, long 270° focus rotation, and standardized gear placement for seamless integration into professional cinema workflows.

Support for Cooke /i Technology and ZEISS eXtended Data ensures compatibility with advanced metadata workflows used in VFX production and virtual production environments.
