SIRUI Jupiter 28-85mm T3.2 Cine Full-Frame Zoom Lens / Cinema Lens / Video Lens
The SIRUI Zoom Lens 28-85 mm T3.2 with 3x zoom. This lens covers full-frame and larger camera sensors with high sharpness and minimal optical aberration and can be used on various professional camera systems.

3x Zoom
This lens covers a zoom range from wide-angle to medium telephoto (28 mm to 85 mm), greatly simplifying filmmakers' options when shooting. The focus remains unchanged throughout the zoom range, keeping the story consistent and engaging.

Constant T-Stops
For precise exposure control, an aperture range from T3.2 to T22 is offered. Thoughtful designs like a stepless aperture ring and identical gears with 0.8 mm spacing make this lens super comfortable to operate and use.

8K Resolution
The image is sharp without being oversharpened and tends toward a soft vintage look. The transition is smooth and natural with a pleasant bokeh in the background.

Smooth and frictionless focus control
The long focus throw of 259° is designed for precise and smooth focus pulling. The focus ring features a dual scale with feet and meters, allowing the operator and assistant to read the scale simultaneously from different positions.

Focus breathing
Focus breathing is well controlled. No visible focus shift occurs when changing focus.
Hard case
The 28-85 mm cine zoom includes a specially designed hard case that protects against temperature, water, dust, shocks, etc.
