Sigma Aizu Prime 32mm T1.3 LF

Balanced Cinematic Full Frame Prime

The Aizu Prime 32mm T1.3 LF is designed as one of the most versatile focal lengths within Sigma’s Aizu Prime lineup, combining a natural cinematic perspective with the series’ signature ultra-fast T1.3 aperture and large-format coverage. As part of the world’s first full large-format cinema lens lineup with a constant T1.3 aperture across all focal lengths, the lens establishes a new benchmark for modern cinema production.

The 32mm focal length provides an exceptionally balanced angle of view that closely matches natural human perception while still offering cinematic spatial separation and depth. This makes the lens highly effective for narrative filmmaking, handheld cinematography, commercials, documentary work, and dialogue-heavy productions.

Optically, the lens combines modern cinema sharpness with an organic and naturally soft rendering profile. Images maintain high resolution and refined detail while avoiding harsh digital characteristics. The result is a cinematic image with dimensionality, smooth tonal transitions, and elegant falloff behavior.

The constant T1.3 aperture enables filmmakers to achieve extremely shallow depth of field while maintaining excellent low-light performance. Subject isolation appears highly cinematic while focus transitions remain smooth and visually natural. Sigma’s cinema-focused optical design minimizes focus breathing and geometric distortion to maintain visual consistency during focus pulls and dynamic camera movement.

Mechanically, the lens features a robust all-metal cine housing with standardized gear positions, long focus throw, and consistent front dimensions for seamless integration into professional cinema workflows. Despite its large-format coverage and high-speed optical design, the lens remains lightweight enough for modern gimbal, Steadicam, and handheld operation.

Support for Cooke /i Technology and ZEISS eXtended Data enables advanced metadata workflows for VFX-heavy productions and virtual production environments.
