What’s Changed? Unlike its predecessor, the Sigma Cine 20mm T1.5 FF Prime with /i Technology supports Cooke’s /i metadata protocols to communicate with the camera, recording optical characteristics and lens settings to every frame to make post-production easier. This is especially useful when you’re adding effects in post.

Wide-Angle Prime. This lens offers full-frame coverage, giving you a compact, lightweight, wide-angle cine lens. It’s capable of delivering 6K to 8K resolution, and its fast T1.5 aperture allows depth-of-field control and low-light shooting flexibility.

High-Quality Optics. The 20mm T1.5’s optics are designed to minimize flare and ghosting while enhancing contrast, even in backlit conditions. You’ll get exceptional bokeh, and maximum sharpness across the frame.

Standardized Features. Each lens in Sigma’s FF series shares common focus and iris gear ring positions, enabling quick and easy lens change when using accessories like follow focuses, matte boxes, and lens-control motors. Color balance is standard across this series for easier color correction. The stepless, 0.8 pitch gear aperture and focus rings allow you to use follow focus without the need for clunky gears. Lateral aperture and distance markings make it easy to pull aperture and focus from either side.

That Build Quality Though. Each ring on this lens is sealed, making it both splash-proof and dust-proof. Its markings are laser engraved and a luminous paint job helps you work in the dark. This lens’s body is constructed completely of metal and includes a built-in support foot to prevent undue stress on your camera’s lens mount.
