And thanks to their robust, cine-style housing (which also allows for the use of a follow-focus system), their full-frame coverage and interchangeable mounts, they will be reliable partners for years to come.;Application;The size and weight of the Compact Zoom CZ.2 make the lens perfect. Both Zoom Lenses are colormatched not just to eachother, they fit perfectly to all ZEISS prime lenses.;The Zoom lenses are ideal for top-quality movies, feature films productions and documentaries. With their outstanding color matching, typical for ZEISS, they make an optimal addition to the Master Prime, Ultra Prime and Compact Prime.;The Compact Zoom CZ.2 70-200mm T/2.9 comprises all the features of a cine-style lens. Extra-long focus throw, constant T-stop of 2.9 across the entire zoom range and easy-to-read markings. But the main difference to a regular photo zoom lens is a phenomenon called “focus shift”. When zooming in on an object with a photo zoom lens you always have to adjust focus. As soon as you change the image frame the position of the sharp plane of focus changes as well. In still photography this is not a problem. But in motion picture it is a big issue because your details might be out of focus. Your scene is ruined.;A highly precise mechanical adjusting concept is used to compensate this negative effect with the Compact Zoom CZ.2 70-200mm T/2.9. The goal is to stabilize the image position while zooming. Three independent lens movements are necessary to achieve this. You have a sharp crisp image without refocusing.
