Description — Cooke 18mm T2.8
The Cooke 18mm T2.8 miniS4/i is a Prime cinema lens in the Wide Angle focal length category, built specifically for Super 35 format cinema production. It features a PL Mount, the professional standard for digital cinema cameras, and a maximum aperture of T2.8 — a true T-stop rating that reflects actual light transmission for consistent exposure matching across a lens set. Weighing 1,300 grams, it is designed to handle the demands of professional rigged camera builds.
Focus is manual only, which aligns with standard cinema production practices where a focus puller manages critical focus adjustments. The lens carries no image stabilization, placing stabilization responsibility on the camera rig or support system. With its 18mm fixed focal length, it delivers a wide perspective suited to a broad range of cinematic applications, from large-scale environment shots to confined interior scenes.
This is a straightforward, purpose-driven tool for Super 35 cinema work.

The Cooke 18mm T2.8 miniS4/i is designed to cover Super 35 format sensors, which is the most common sensor size in professional digital cinema production.
Is the T2.8 aperture the same as f/2.8?+
No. T-stops measure actual light transmission through the lens, whereas f-stops are a theoretical calculation based on focal length and aperture diameter. T2.8 is the value specified for this lens and should not be treated as equivalent to f/2.8 when matching exposure across a lens set.
Does this lens support autofocus?+
No, the Cooke 18mm T2.8 miniS4/i is a manual focus lens only. This is consistent with professional cinema lens design, where focus pulling is performed manually by a dedicated crew member.
How heavy is this lens?+
The lens weighs 1,300 grams, which is a practical weight for integration into a rigged cinema camera build without placing excessive strain on the camera body or support system.
