Description — Sigma 85mm T1.5
The Sigma 85mm T1.5 Cine Lens is a prime lens designed for cinema and video applications, built around a PL mount to integrate with professional cinema camera systems. Its T1.5 maximum aperture delivers strong low-light capability and pronounced depth-of-field control at the 85mm telephoto focal length. The lens provides full-frame image circle coverage, supporting larger-format cinema sensors without compromise.
Focus is entirely manual, with no autofocus capability — a deliberate design choice that fits professional cine production environments where focus pullers manage a follow-focus system. Image stabilization is absent, as is standard for cinema primes used on stabilized rigs or locked-off camera setups. The lens features an 86mm filter thread, and its overall weight comes in at 1,245g, reflecting the robust construction expected in a professional cinema context.
Whether used on dramatic narrative productions or high-end commercial work, the fixed focal length and calibrated T-stop make this lens a reliable tool for consistent, repeatable exposure in multi-lens cinema sets.
