The Sigma Cine 85mm T1.5 is a portrait-oriented prime designed to deliver elegant subject isolation and a flattering sense of compression. On full-frame cinema sensors, the 85mm provides a cinematic close-up perspective that highlights emotion and detail while maintaining a comfortable working distance. The fast T1.5 aperture enables smooth, expressive depth transitions and strong low-light versatility, making it ideal for character-driven storytelling, interviews, and commercial beauty work. Optically, the 85mm offers high resolving power with refined highlight rolloff and minimal chromatic aberration, producing a polished, natural image. Mechanically, it maintains the Sigma Cine design consistency with a 95 mm front diameter, standardized gear placement, and a 180° focus rotation for precise, repeatable marks. The lens is available in ARRI PL, Canon EF, and Sony E mounts, each supporting native metadata protocols. With durable all-metal construction, the 85mm T1.5 is a reliable and cinematic portrait focal length in the Sigma Cine Prime set.
