SIGMA has announced its new Aizu Primes, which it states are the world’s first large-format cinema lenses to feature a constant T1.3 aperture across all focal lengths. The lenses will be available in either PL or Sony E mount.
We had a look at the new lineup at Cine Gear 2025.
All of the lenses cover a ⌀46.3mm image circle, ensuring 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.
According to SIGMA, the Aizu Primes combine modern sharpness with an organic and naturally soft look.
The lineup will eventually consist of 12 focal lengths ranging from 18mm to 125mm. The initial release includes 8 lenses with focal lengths from 25mm to 75mm. It’s great to see Sigma release several key focal lengths all at once, as it makes it difficult to buy one or two every few months to get a full set. Nicely done, Sigma!
All lenses in the Aizu Prime lineup feature an optical system developed specifically for cinema applications. The lenses are said to have modern sharpness, but still provide an organic look. Distortion and focus breathing are claimed to be minimized.
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.
SIGMA states that all the lenses have consistent color balance, contrast, and flare characteristics.
The Aizu Prime lenses are relatively lightweight, weighing in at between 1.6-1.7kg / 3.5-3.7 lbs, allowing them to be used on a dolly, Steadicam, or gimbal and handheld operation.
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.
