The Sigma Aizu Prime 125mm T1.3 LF Cinema Lens (ARRI PL, Feet) pairs a powerful telephoto perspective with the elegant, organic rendering of Sigma's Aizu Prime series. Designed for full-frame and large-format cinema cameras, this 125mm prime maintains the series' remarkably fast T1.3 aperture, providing cinematographers with exceptional control over depth of field, subject isolation, and low-light imagery.
The Aizu Prime series is engineered to deliver an organic, moderately sharp look that emphasizes expressive cinematic character rather than an overly clinical appearance. The longer 125mm focal length creates pronounced visual compression and naturally isolates subjects within the frame, making it particularly effective for close-ups, portraits, dialogue scenes, beauty work, and tightly composed detail shots.
Its ultrafast T1.3 maximum aperture further enhances the 125mm's ability to produce exceptionally shallow depth of field. This combination allows filmmakers to separate subjects dramatically from foreground and background elements while precisely directing the viewer's attention. The wide aperture also provides valuable flexibility when shooting in available-light or low-light environments.
Designed with minimal distortion and coverage for full-frame and large-format sensors, the 125mm maintains the refined visual characteristics established throughout the Aizu Prime family. A consistent T1.3 aperture across the series helps simplify lens changes by providing predictable exposure characteristics and a cohesive visual language across different focal lengths.
Combining strong telephoto compression, large-format coverage, exceptional T1.3 speed, and Sigma's distinctive organic rendering, the Sigma Aizu Prime 125mm T1.3 LF Cinema Lens is a premium choice for narrative filmmaking, commercials, music videos, portraits, and other professional productions where expressive subject separation and cinematic character are essential.
Lens Metadata
Each ARRI PL-mount Aizu prime lens uses ZEISS eXtended technology that provides real-time lens metadata while shooting. It also lets you export distortion and shading correction data to assist in post and visual effects production. The PL-mount Aizu lenses also output Cooke /i data when used with a compatible lens mount.
Full-Frame Coverage
With an image circle of 46.3mm, Aizu primes cover not only full-frame and Super 35 sensors but are compatible with large-format camera options like ARRI ALEXA LF Open Gate and VistaVision.
Consistent Look Across Series
Offering a quietly elegant and natural look, all Aizu focal lengths produce a consistent look with minimal breathing and distortion and balanced color, contrast, and flare characteristics.
Impressive Close-Ups
Short minimum focus distances help you cozy up to your subject, creating impactful close-ups and adding visual tension.
Compact and Lightweight Design
Developed from the Sigma High-Speed Prime series, the Aizu lenses' cine-style design features a lightweight, compact form, 0.8 MOD gears that are compatible with professional lens control systems, and a support foot with both 1/4"-20 and 3/8"-16 threads. The durable housing has a wide 270° barrel rotation that enables precise focus pulls.
114mm Front Diameter
The front outside diameter of 114mm fits many pro matte boxes and lens shades.
Focus Marks in Feet
Focus distances are measured in feet, and like all marks on the Aizu lenses, use luminescent paint for easy visibility.
