A staple of cinematic storytelling, the 35mm Aizu Prime captures scenes with a grounded, human perspective. Known for its versatility, this focal length balances environment and subject with elegance—now elevated by a blazing-fast T1.3 aperture for enhanced low-light performance and exquisite background separation.
Sigma’s Aizu Prime series redefines practicality in cinema optics. As the world’s first large-format cine lens lineup to achieve a consistent T1.3 aperture across all focal lengths, Aizu Primes offer unmatched versatility and creative freedom. Designed exclusively for cinema and manufactured in Sigma’s state-of-the-art Aizu facility in Japan, these lenses deliver a beautifully balanced image—combining modern sharpness with a smooth, organic character.
With compact, lightweight housings, extended data support, luminous engraved markings, and excellent close-focus performance, Aizu Primes are built for the demands of modern productions. Focus breathing is carefully suppressed, distortion is minimal, and performance remains consistent from 18mm to 125mm—setting a new standard for high-end cinematography.
