For added versatile high performance, this high-speed zoom lens offers a high F2.8 constant aperture brightness over the entire zoom range and a focal length of 12-35mm (35mm camera equivalent: 24-70mm) to cover wide-angle to standard to medium telephoto shooting. What?s more, the stunning AF performance of this lens records excellent 4K video where precise focusing is essential.
