Description — Sigma 85mm T2.5
The Sigma 85mm T2.5 Cine Lens is a prime telephoto lens designed for full-frame cinema and video production, mounted on the industry-standard PL Mount. With a fixed 85mm focal length and a maximum aperture of T2.5, it delivers a consistent and calibrated exposure performance that makes it a strong candidate for use within a matched cinema lens set. The lens is built exclusively for manual focus, reflecting the professional cinema workflow where focus control is handled independently by a trained focus puller.
Weighing 1,400g, the lens is substantial but appropriate for its class, and the 95mm filter thread ensures compatibility with standard cinema matte boxes and filtration accessories. The full-frame image circle means this lens is ready for the demands of modern large-format and full-frame cinema sensors. With no image stabilization and no autofocus, this lens is purpose-built for controlled production environments — studio shoots, narrative productions, and any setting where a full camera crew is in place.
