Sigma Aizu Prime 50mm T1.3 LF Lens for ARRI PL

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.

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 which delivers a natural, organic look. They provide quiet elegance and depth to the image, with distortion and focus breathing carefully minimised 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 colour 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 Super35 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 depth to the imagery.

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.
