About Cooke S7/i

When capturing cinematic visuals that push the boundaries of visual storytelling, the 21mm T2.0 S7/i Plus Prime Lens for PL Mount stands as a paragon of optical excellence. Engineered by Cooke, a brand synonymous with precision and the coveted 'Cooke Look', this lens is meticulously crafted to accommodate the expansive requirements of 35mm, Super 35mm, Full Frame, and VistaVision formats, ensuring compatibility with the latest full frame cinema camera sensors with an image circle of at least 46.31mm.

The S7/i Prime series is renowned for its versatility, allowing filmmakers to seamlessly transition between various formats without compromising on image quality. The 21mm T2.0 lens is no exception, offering a harmonious blend of practicality and high-end performance. Its optical design is optimized for maximum sharpness and contrast at full aperture, with exceptional control over flare, veiling glare, distortion, and spherical aberrations.

Color consistency is paramount in multi-lens productions, and this lens is color matched to integrate flawlessly with the Anamorphic/i, S4/i, miniS4/i, 5/i, and Panchro/i Classic lenses, maintaining the integrity of the Cooke family color palette across your footage.

Incorporating the advanced /i Technology, this lens enables the automatic capture of critical metadata such as lens settings, focusing distance, aperture, depth-of-field, hyperfocal distance, and even the lens' serial number. This data streamlines post-production workflows and enhances on-set efficiency, particularly for VFX-intensive projects.

The craftsmanship behind the 21mm T2.0 S7/i Plus Prime Lens is evident in every aspect of its construction. Traditional grinding and polishing techniques are employed to achieve unparalleled precision, while meticulous metrology ensures each lens meets Cooke's rigorous quality standards. High-temperature vacuum evaporation techniques are used to apply thin-film coatings to the glass, enhancing image quality and durability.

The lens' external finish features a scratch-resistant PTFE hard anodized coating, designed to withstand the rigors of challenging shooting environments. Its robust construction is paired with a thoughtful design, including large focus scales with clear numerals and an engraved entrance pupil position, aiding focus pullers in even the most demanding lighting scenarios.

Compatibility is key, and the 21mm T2.0 S7/i Plus Prime Lens maintains a common front diameter of 110mm across most of the Cooke S4/i Prime range, with standardized focus and iris drive gears. The eight-leaf linear module iris assembly provides a smooth aperture range from T2 to T22, while the cam-style focus movement ensures precise and smooth focus adjustments.

Balanced for both handheld and Steadicam use, this lens is designed to pair seamlessly with the latest compact cinema cameras, offering a comfortable weight-to-size ratio for dynamic shooting. The hardened PL mount with /i Technology contacts ensures a secure and reliable connection to your camera system.

In summary, the 21mm T2.0 S7/i Plus Prime Lens for PL Mount is a testament to Cooke's legacy of optical innovation, delivering unmatched image quality, reliability, and versatility for filmmakers and cinematographers who demand the very best.
