Description — Sirui 28-85mm T3.2 EF Mount
The Sirui Jupiter 28-85mm T3.2 is a manual-focus cinema zoom lens built for Super 35 format cameras and fitted with a PL Mount. The focal length range of 28mm to 85mm places it in the standard zoom category, covering wide-angle through short-telephoto perspectives — a range that suits a wide variety of cinematic applications from establishing shots to medium close-ups. The constant T3.2 maximum aperture is one of the lens's most practical attributes, maintaining consistent exposure across the entire zoom range without requiring iris compensation.
With a weight of 2,540g, this is a substantial piece of glass built to cinema-grade standards, designed for use on professionally rigged camera setups. Focus is fully manual, in keeping with the demands of scripted production where repeatable, precise focus marks are essential. There is no image stabilization onboard, which is consistent with cinema production practice.
The PL Mount configuration ensures the lens integrates directly with the cinema camera ecosystem built around that standard, and the Super 35 format coverage matches the sensor size found in many widely used cinema camera platforms.
