Cooke S7/i Full Frame Plus Primes

Cooke S7/i FF Lenses are designed to provide maximum performance at full aperture with superior control of flare, distortion and spherical aberration. They have been optimized for film and digital cameras reducing lateral color aberration and providing an organic bokeh. The S7/i series are a comprehensive line-up of 16 focal lengths from 16mm – 300m. Cooke S7/i primes perform well in low light situations. They can produce crisp, fine details and a soft bokeh. 

Large format coverage means you can pair with Super 35mm, current full frame, VistaVision, plus upcoming cameras. All Cooke S7/i prime lenses are color-balanced, color-matched, and compatible with Cooke S4/i, miniS4/i, Anamorphic/i and PANCHRO/i Classic lenses. A nine-leaf linear module iris assembly is fitted into the Cooke S7/i Primes.

Cooke S7/i lenses feature a hardened PL mount with /i Technology contact. The durable exterior includes a scratch resistant PTFE hard anodized finish is provided on all Cooke lenses, providing a hard-wearing surface to meet the most demanding environmental conditions.

Optical Design

The optics are designed to grant maximum performance at full aperture T2.0* with superior control of flare, distortion, and spherical aberration. S7/i lenses offer superb optical and mechanical performance, control of flare, distortion, veiling glare and spherical aberrations at full aperture.
^{*300mm is a T3.3}

These lenses are especially well-balanced for astigmatism and correct for lateral and longitudinal aberrations over the entire image area.

Focus Movement

Cooke's Academy Award® winning cam-style focus movement coupled with the added benefit of a large lens barrel diameter, has allowed for an increased number of focus markings, particularly at close focus.

Every index mark is labeled. More detailed markings allow for more detailed focus control so you can get it right the first time. In addition, Large, clear numerals on both sides of the focus barrel benefit the focus puller when shooting under difficult lighting conditions.

Spherical aberration has been controlled throughout the range of focal lengths to eliminate compensation of changes in back focus with aperture. A four-point contact bearing provides a smooth positive backlash-free movement. The cam-type focus mechanism allows for smooth focus adjustments. Modular construction increases ease of maintenance and serviceability. 

The entire family offers 0.8 mod focus drive gears with 140 teeth.

/i Technology Logo Technology

S7/i lenses come equipped with /i Technology for frame by frame digital information capture, as do all modern Cooke cine lenses for film and digital capture. They are designed for all PL mounted professional motion picture film and electronic cameras.

/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
• Focal length (both metric and imperial)
• Zoom position (when applicable)

/i Technology is accessible via a cable connector near the lens mount and contacts inside the mount which sync with /i compatible cameras and accessories.
