Sigma has expanded its Aizu Prime cinema lens lineup with the addition of three new T1.3 LF models: the 21mm, 100mm, and 125mm. These join the existing eight lenses in the series, which previously covered focal lengths from 25mm to 75mm. The expansion significantly broadens the creative range available to filmmakers and content creators using the Aizu Prime system.

All new lenses maintain the consistent T1.3 maximum aperture across the lineup, ensuring uniform exposure and depth of field control when switching between focal lengths. This consistency is a key advantage for creators who rely on predictable lighting and bokeh characteristics during dynamic shoots. The LF designation indicates compatibility with large-format sensors, supporting high-resolution cinema cameras now widely used in professional and indie productions.

By filling the gaps at both the wide and telephoto ends, Sigma enables creators to tackle a wider variety of scenes—from tight interiors and landscapes to distant subjects and compressed portraits—without changing lens systems. The move responds to growing demand for modular, high-quality cinema glass that balances performance, consistency, and versatility.

The updated lineup strengthens Sigma’s position in the competitive cinema lens market, offering a compelling option for creators building or expanding their prime lens kits. With coverage now spanning 21mm to 125mm at a constant T1.3, the Aizu Prime series provides a flexible, professional-grade solution for narrative, documentary, and commercial work.

No pricing, availability, or technical specifications beyond those mentioned in the announcement were disclosed in the source. Creators are advised to consult Sigma’s official channels for detailed information on pre-orders, compatibility, and release timelines.
