Cooke S4I T2 (18,25,32,40,50,65,75,100,135mm)

Award winning Cooke S4 Prime Lenses were designed and developed in close technical collaboration with industry professionals. They are colour-matched and compatible with all contemporary Cooke cine lenses.

Cooke S4 optics offer superb optical and mechanical performance, control of flare, distortion, veiling glare and spherical aberrations at full aperture. The cam-type focus mechanism allows for smooth focus adjustments. Modular construction increases ease of maintenance and serviceability.


All of our S4 Prime lenses are now equipped with /i Technology, as of February 2005. S4/i lenses are designed for all PL mounted professional motion picture film and electronic cameras. The /i Technology provides cinematographers and camera operators with vital information on lens setting, focusing distance, aperture and depth-of-field, hyperfocal distance, serial number, owner data, lens type and focal length in both metric and footage measurements. For zoom lenses, the zoom position is displayed.

For companies interested in producing compatible products with /i Technology, the /i protocol is available as a free download: See "Cooke /i User's Guide & Technical Manual" in PDF format under Technical Resources, Free downloads.

65 Soft Effects Attachment

The 65 Soft Effects is made for the S4/i 65mm and 75mm lenses (via Cooke 75mm adapter ring). The design for the attachment is based on Cooke's PS945 soft focus lens for 4x5 large format photography. See more about the soft focus effect in sample photos taken with the PS945 lens. The effect is high resolution with a stunning glow to the highlights -- subtle, but most pronounced wide open at T2, becoming less pronounced as you stop down. (Effect from T2 to T4 with the 65mm lens; T2 to T5.6 with the 75mm lens.)
