Ny Cooke-zoom
Nu har Cooke Optics sitt nya zoomobjektiv klart för leverans från januari månad 2006. Det är en kompakt och ljusstark zoom med brännvidderna 15–40 mm, T2.0
Cooke S4/i 15-40mm T2 CXX Zoom
Superior performance and ease of operation is exactly what you expect from Cooke lenses, but the new 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 (patent pending)
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.
Save Time and Money – /i Technology is the Key
Over the next few months, Cooke will introduce a technological breakthrough that will reshape and streamline the systems involved with filmmaking, beginning with the efforts of cinematographers through post production. It will have the potential of saving you significant time and money. Cooke /i technology is the key and the Cooke CXX zoom is the only zoom that has it.
The CXX Zoom works well with the Arri LMB4 clip-on matte box.
