A brilliant match for Sony E-mount full-frame cameras: This 24-70mm f/2.8 lens from Sony gives you a moderate wide-angle to medium-telephoto focal range, useful for everything from landscape and architecture shots to portraits and detailed close-ups. A constant f/2.8 aperture throughout the zoom range lets you easily change focal lengths without having to alter your exposure settings. Improving on a versatile professional zoom lens: This lens is noticeably lighter and a little bit smaller than its excellent predecessor, the Sony FE 28-70 f/2.8 GM .
