Featuring eight lens elements in five groups with two aspherical elements, the brand new optical design on the SAL50F14Z lens is optimized for use with Sony’s full-frame α99 camera.   The lens maintains exceptional resolving power and contrast at all apertures, and utilizes a rear-focus system to focus smoothly, quietly and effectively.   It is also dust- and moisture-resistant, extending the appeal to a wide range of outdoor shooting applications.
