Description — CHIOPT 28-85mm T3.2 Cine Zoom
The CHIOPT XTREME ZOOM 28-85mm T3.2 is a dedicated cine zoom lens built for full-frame cinema and video production. It mounts via Canon EF and spans a focal length range of 28mm to 85mm, classified as a standard zoom. The lens maintains a constant T3.2 aperture across the entire zoom range, which is critical for maintaining even exposure during zoomed shots in professional cinematography.
Focus is entirely manual, making it the right tool for productions using follow focus rigs or remote lens control systems. There is no image stabilization, so it is designed to be used in stabilized production setups. At 2,721.6g, this is a heavyweight lens built for rigged cinema environments.
It covers the full-frame format, ensuring edge-to-edge coverage on large-sensor cameras. The Canon EF mount ensures compatibility with a broad range of full-frame cinema and DSLR bodies. For cinematographers working on commercial, narrative, or high-end video productions who need a consistent, controllable zoom with a manual cine-style workflow, the CHIOPT XTREME ZOOM 28-85mm T3.2 is purpose-built for that environment.

Frequently Asked Questions — CHIOPT 28-85mm T3.2 Cine Zoom
What cameras is this lens compatible with?+
The CHIOPT XTREME ZOOM 28-85mm T3.2 is designed for cameras with a Canon EF mount. It is built for the Cinema / Video camera system and covers the full-frame format, so it is best paired with full-frame Canon EF-mount cinema cameras or DSLRs.
Does this lens have autofocus?+
No, this lens is manual focus only with no autofocus capability. This is consistent with its cine lens design, which is intended for use with follow focus systems or remote lens control setups in professional production environments.
Is the T3.2 aperture constant throughout the zoom range?+
Yes, the maximum aperture is T3.2, and as a cine zoom lens with a single listed aperture value, it maintains that constant T-stop across the 28–85mm focal length range. This is important for maintaining consistent exposure when zooming during a shot.
Does the lens have image stabilization?+

How heavy is this lens and what does that mean for my setup?+
The lens weighs 2,721.6g, making it a substantial piece of equipment. It is best suited for rigged production setups — such as a matte box-equipped cinema rig or tripod-mounted configuration — rather than lightweight or handheld shooting.
