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. Following the 8 lenses released in 2025, three more lenses－21mm, 100mm, and 125mm―are now being released, bringing the lineup to 11 lenses spanning ultra-wide-angle to telephoto. This comprehensive system 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.

Compatible with the Cooke /i + ZEISS eXtended Data
The Aizu Prime lenses are compatible with Cooke /i + 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.
