Lens Overview — CHIOPT 28-85mm T3.2 Cine Zoom

The CHIOPT XTREME ZOOM 28-85mm T3.2 is a full-frame cine zoom lens designed for professional cinema and video productions. Built around a Canon EF mount, it covers a focal length range of 28mm to 85mm, making it a versatile standard zoom suitable for a wide variety of shooting scenarios — from wide environmental shots to tighter mid-range compositions. The lens operates at a constant T3.2 aperture throughout the zoom range, ensuring consistent exposure as you zoom during a shot.

It is strictly manual focus, with no autofocus capability, which is standard for dedicated cine lenses used with follow focus systems and remote lens control setups.

The lens is designed for the full-frame format, making it compatible with large-sensor cinema cameras and DSLRs using the Canon EF mount.

Weighing in at 2,721.6g, this is a substantial piece of glass intended for rigged production environments rather than handheld run-and-gun use. Overall, it is a purpose-built tool for cinematographers who prioritize optical consistency and manual control in high-end production workflows.
