Sigma Corporation (CEO: Kazuto Yamaki) is pleased to announce the launch schedule of the “Aizu Prime Line,” a new series of interchangeable lenses for cinema production under the “Sigma Cine Lens” brand.

The Aizu Prime Line sets a new benchmark in filmmaking as the world’s first full lineup of large-format cinema lenses with a consistent T1.3 aperture across all focal lengths. Designed to deliver both modern sharpness and a naturally soft, organic look, these lenses offer rich texture, depth, and expressive power. With 12 lenses ranging from 18mm to 125mm—including an initial release of 8 core lenses from 25mm to 75mm—this system is built to meet the diverse demands of cinematic storytelling.

Engineered specifically for cinema, the Aizu Prime lenses feature an optical design that minimizes distortion and focus breathing while maintaining a consistent visual character across the lineup. The large φ46.3mm image circle supports full-frame, Super 35, and large-format cameras, ensuring compatibility with cutting-edge systems like the ARRI ALEXA LF and VistaVision. With a short minimum focusing distance, these lenses also excel in close-up work, delivering dramatic, high-impact visuals.

Despite their ultra-fast T1.3 aperture and large-format coverage, the lenses remain compact and lightweight—ideal for handheld, gimbal, and Steadicam use. Built with precision and durability in mind, they offer smooth operation and support ZEISS eXtended Data for real-time metadata and streamlined VFX workflows. The Aizu Prime Line is a powerful, versatile toolset for filmmakers seeking both technical excellence and artistic expression.
