The CXX takes the classic Cooke Look and applies it throughout the zoom range of an incredibly fast zoom lens. Variable Vignetting Stop – developed by Cooke, allows the high speed CXX lens to maintain T2.0 speed and high resolution throughout the zoom range. It adjusts automatically. The benefit to you: No ramping. No flare. And of course, you can count on Cooke's standard /i Technology integration for an array of metadata.
