Lens Overview — Sigma 85mm T1.5 FF

The Sigma 85mm T1.5 FF Cinema Prime is a full-frame cine lens mounted in the industry-standard PL Mount, making it compatible with a wide range of professional cinema camera systems. With a focal length of 85mm and a maximum aperture of T1.5, this is a compelling choice for cinematographers who demand strong low-light performance and the ability to work with a shallow depth of field. The T1.5 rating is a true transmission value, giving directors of photography a reliable and consistent exposure reading across a matched cine lens set.

At 85mm on a full-frame format, this lens sits comfortably in the portrait and medium telephoto range, making it well-suited for close-up character work, interview setups, and scenes that benefit from natural background separation. The lens is manual focus only, which is standard practice in professional cinema workflows where a dedicated focus puller operates the lens via a follow focus system. Weighing in at 1,210g, it has a substantial, production-ready build.

Image stabilization is not present, which is typical for a lens in this category intended for use on stabilized rigs or gimbals.

Description — Sigma 85mm T1.5 FF

The Sigma 85mm T1.5 FF Cinema Prime in PL Mount is a manual focus prime lens built for full-frame professional cinema cameras. With a maximum aperture of T1.5, it delivers a true light transmission value that cinematographers can rely on for consistent exposure across a matched lens set. The 85mm focal length places this lens in the standard-to-medium telephoto range, making it particularly effective for dialogue scenes, close-up character work, and any situation where natural subject-background separation is desirable.

It is a Prime lens with a fixed focal length, which suits productions that prioritize optical quality and a deliberate, controlled shooting approach. The lens weighs 1,210g, reflecting a solid cinema-grade construction. Image stabilization is not included, so this lens is best paired with a stabilized support system.

With its PL Mount, it slots directly into established professional cinema camera ecosystems without adapters.
