The miniS4/i primes (T2.8 to T22 aperture) incorporate everything that today's filmmakers require: smaller, lightweight lenses that offer the same resolution, optical quality and reliability as the S4/i lenses.
High-performing
The same exceptional resolution and optical quality as the S4/i, but at a lower price point.
Lightweight
Enjoy a smaller, lighter lens without compromising on quality.
Reliable
All Cooke lenses are colour matched, meaning miniS4/i and S4/i lenses can be mixed on a shoot with full confidence.
Streamlined
Automatically record key lens data for each frame shot with /i Technology.
i/Technology
Cooke’s /i Technology enables film and digital cameras to automatically record key lens data such as focusing distance, aperture and depth-of-field for every frame shot and provide it to post-production teams digitally. Streamlining production and post, it saves time and cost while eliminating guesswork and enabling greater creative freedom.
You expect and get superior performance and ease of operation from Cooke lenses. The Cooke S4/i 15-40mm CXX zoom lens offers attributes beyond great optical and mechanical performance for 35mm/Super 35mm formats:
New Variable Vignetting Stop
Cooke's new Variable Vignetting Stop allows the high speed CXX lens to maintain T2.0 and high resolution throughout the zoom range. This innovative mechanism adjusts automatically. The benefit to you: no ramping and no flare.
Light and Bright
T2, of course. Light and comparable in size to a Cooke S4/i prime telephoto lens. And like our S4/i telephoto lenses, the CXX zoom offers an extraordinary close focus: Under 7 inches from the front element. And like the Cooke S4/i Primes - no breathing.
