The Sony A 70-400mm f/4-5.6 G II is a long-range telephoto lens for Sony A-mount cameras, and an update to the original Sony 70-400mm f/4-5.6G SSM.

Super Telephoto Zoom. The full-frame compatible 70-400mm focal length enables you to capture subjects at great distances. The f/4-5.6 aperture is fast enough for normal daylight use, but it’s probably a bit too slow for low or indoor lighting.

SSM Motor with Improved Autofocus Performance. The Super Sonic wave Motor is powered by piezoelectric elements that change shape when voltage is applied, enabling fast, responsive autofocusing. While its predecessor offered decent autofocus performance, this lens features an LSI drive circuit that makes object-tracking performance four times faster.

G-Series Optics. The advanced eighteen-element/twelve-group optical formula features two ED elements that minimize chromatic aberrations, while the internal focusing design allows for faster performance.

Three Focus Hold Buttons. With any A-mount camera, pressing one of the buttons holds your focus point. However, on advanced models like the Sony Alpha a99 II, you can program these buttons to perform additional functions.
