Introducing the Aizu Prime Line―the world's first lineup1 of large-format
cinema lenses to achieve an aperture value of T1.3 across all focal lengths.

The lineup combines modern sharpness with an organic and naturally soft
look, bringing rich texture and depth to visuals.

Boasting unparalleled brightness, refined expression, and reliable
performance, the Aizu Prime Line embodies the proven technology and
quality of “Made in Aizu, Japan” establishing the new standard.

lengths from 25mm to 75mm, covering core cinematic production needs.

Key features

Expressive power for profound beauty

A consistent T1.3 across all focal lengths

The T1.3 aperture enables exceptionally shallow depth of field and graceful
bokeh, seamlessly separating the subject while preserving a natural sense of
depth and dimensionality. This refined visual language draws the viewer
into the frame with a subtle yet powerful presence.

Optical design for the demands of cinema

All lenses in the Aizu Prime lineup feature an optical system developed
exclusively for cinema applications. While maintaining modern sharpness,
they avoid rigid or harsh depictions—delivering a natural, organic look. They
provide quiet elegance and depth to the image, with distortion and focus
breathing carefully minimized to ensure visual consistency, even in dynamic
scenes.

Huge perspective range coverage

The Aizu Prime Line is designed as a system to cover a wide range of focal
lengths from 18mm to 125mm. Initially 8 core lenses ranging from 25mm to
75mm are being released, followed by 18mm and 21mm wide-angle lenses,
and 100mm and 125mm telephoto lenses. This comprehensive system,
covering from ultra-wide-angle to telephoto, is adaptable to diverse scenes
and compositions, and supports a wide array of visual expressions.

Completely consistent look

Consistency of color balance, contrast, and flare characteristics ensures
seamless integration between scenes, bringing a high level of harmony to
the entire visual narrative across the entire lineup from 18mm to 125mm.

φ46.3mm image circle

The large φ46.3mm image circle ensures full coverage not only for full-frame
and Super 35 formats, but also for the latest large-format cameras such as
the ARRI ALEXA LF Open Gate and VistaVision. This capability enables
uncompromised filmmaking across a diverse range of projects.

High-impact close-up expression

The short minimum focusing distance enables striking close-up shots. By
getting closer to the subject, the Aizu Prime lenses create visual tension and
dramatic effects, adding impactful depth to the imagery.

Compact, Precise, Reliable

A compact design that unleashes creativity

Despite being built for large-format coverage and featuring an ultra-fast
T1.3 aperture, the Aizu Prime lenses remain remarkably lightweight. This
rare balance of exceptional speed and mobility offers the flexibility and
creative freedom demanded by modern productions—from dolly and
Steadicam to gimbal and handheld operation.

Precise operation and durability

The Aizu Prime lenses offer precise control, exceptional durability, and ease
of maintenance. Despite its compact housing, it delivers unwavering
reliability in demanding shooting environments. Every mechanical detail—
from the wide focus rotation angle to the equal-pitch aperture ring—
embodies the engineering expertise cultivated through the Sigma High
Speed Prime series.

Supports ZEISS eXtended Data

The Aizu Prime lenses support ZEISS eXtended Data, offering real-time lens
metadata during shooting. It also enables the export of distortion and
shading correction data, streamlining workflows for VFX productions.
