The Cooke Varotal 20-100mm zoom lens was released in 1971. It was the first high quality Cooke zoom designed for professional motion picture photography that incorporated a totally new design concept that has remained the basis for all Cooke zoom lenses subsequently produced. It can be used for a more vintage look or to soften and give a film like feel on digital camera images.
