Cooke SP3 18mm T2.4 Full Frame Prime Lens

Ultra-wide cinematic control

The Cooke SP3 18mm T2.4 Full Frame Prime Lens delivers an ultra-wide field of view designed for immersive storytelling, architectural work, and dynamic handheld cinematography. It is engineered as part of Cooke’s modern mirrorless-focused SP3 series, translating the renowned Cooke Look into a compact, lightweight optical system optimized for full-frame sensors.

Despite its wide-angle perspective, the lens maintains exceptional edge-to-edge sharpness while preserving the organic rendering Cooke is known for. Skin tones remain natural, contrast transitions are smooth, and highlights roll off with cinematic precision rather than harsh digital clipping. This makes the 18mm SP3 particularly effective for narrative filmmaking, documentaries, and high-end commercial production.

The mechanical design is optimized for modern gimbal and run-and-gun workflows. Its compact form factor supports lightweight camera builds without compromising precision in focus control or optical consistency across the SP3 series.
