The 25mm S4/i T2 Prime Lens from Cooke features optimal optical performance, /i Technology lens data transfer, and an ergonomic mechanical design with smooth, cam-based focus adjustments. This 25mm lens incorporates an aperture range of T2.0 to T22, focus scales marked in both feet and meters, and color matching with other modern Cooke cine-style lenses. The S4/i lenses minimize flare, distortion, veiling glare, and spherical aberrations even at the full aperture setting. The S4/i lenses are PL-mounted, making them compatible with most professional cine-style cameras.

Cooke's /i Technology provides a wealth of lens data crucial for matching shots, VFX work, and post-production. Metadata parameters include focal length, focus distance, lens aperture, depth of field, hyperfocal distance, the lens serial number, and more. A modular design ensures easier maintenance and servicing of the S4/i lens series.

Focus marks are engraved in large, clear numerals in feet on one side of the barrel and in meters on the other.

The 110mm front diameter is compatible with most matte boxes and adapters and is common to most of the S4/i series.

An eight-blade linear iris provides an aperture range of T2.0 to T22.
