The Sony SAL-70400G 70-400mm f/4-5.6 G SSM Lens is a 5.7x super telephoto lens, specifically designed for the Sony Alpha SLR series. When mounted to Sony APS-C format Alpha DSLRs, this zoom lens achieves a phenomenal 105-600mm focal length (35mm equivalent). As part of the G series of high quality lenses, the SAL-70400G is designed to deliver extremely sharp performance across its wide focal length range, and it is well suited for sports, action, or wildlife photography.

This lens features high-speed SSM (SuperSonic-Wave Motor) for autofocus speed and precision, and the focus-mode/range switch and three focus-hold buttons provide enhanced operability. And when used with the Alpha 900 SLR camera, the AF hold buttons can be customized to activate the intelligent preview function.

• SSM (Super Sonic wave Motor)

A built-in lens motor for faster automatic focusing with high torque at low speed, quick start/stop response, and quiet, smooth operation.

• ED (Extra-low Dispersion) Glass

Two precision ED Glass lenses correct chromatic aberrations and deliver visually accurate results even at full telephoto zoom extension.

• Focus Hold

Three Focus Hold buttons are provided, which lock the focus at the press of a button.

• Focus-Range Limit

Two focus-range limit settings reduce auto-focusing time.

• Circular Aperture

Because the aperture blades form a near circle at the wide openings used for low-light shots, spot-light sources have a pleasing circular defocused effect.

• Tripod Collar

The removable tripod collar rotates 360° so that the camera and lens can be orientated in any position when mounted from above or below.
