Cooke S4i 15-40mm T2.0 CXX PL Mount Zoom Lens

Cooke S4i 15-40mm T2.0 CXX PL Mount Zoom Lens gives you the superior performance and ease of operation that you expect 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.

External Finish
A scratch resistant PTFE hard anodised finish is provided on all Cooke lenses, providing a durable, hard-wearing surface to meet the most demanding environmental conditions.

Focus Movement
Our Academy Award winning cam-style focus movement coupled with the added benefit of a large lens barrel diameter, has allowed for an increased number of focus markings, particularly at close focus. Spherical aberration has been controlled throughout the range of focal lengths to eliminate compensation of changes in back focus with aperture. A four-point contact bearing provides a smooth positive backlash-free movement.
