With this lens in your camera bag, you've got a right to feel ready for anything. It's got one of the wider zoom ranges you'll see in a lens, regardless of manufacturer. At the wide end of the range, you're in portrait territory, and with an aperture of f/4 you'll be able to get nicely blurred backgrounds for pleasing isolation of your foreground subject. But here's something not many portrait lenses have — the ability to zoom from your subject to the beautiful pileated woodpecker that just landed on the tree branch 60 feet behind her.

The lens features a Super Sonic wave focusing motor, for smooth, fast and ultra-quiet focus adjustment. An easy-grip ring assists you when you want to switch over to manual focus, and an auto-clutch ensures that the ring will not rotate in auto-focus mode.

Product Research


Overview: The Sony SAL70400G (70-400mm F4-5.6 G SSM) is a superior quality lens that is an excellent choice for a wide range of medium to long-distance telephoto applications. It has a 35mm equivalent focal length of 105-600mm when used with APS-C format cameras.

Compatibility: The SAL70400G lens is equipped with a Sony A-mount, and is designed for use with Sony Interchangeable Lens Digital Cameras. With an optional LA-EA1 mount adapter, this lens can be used on Sony α (alpha) NEX-series hybrid cameras and camcorders with the E-mount.

G-Series Lens: Sony's G-Series lenses are designed for maximum descriptive power, maintaining excellent peripheral light characteristics and maximizing contrast even at the edges of the frame.

Fast Aperture: The fast F4-5.6 aperture enables you to shoot at higher shutter speeds, making it ideal for sports photography.

ED (Extra-low Dispersion) Glass: The lens is equipped with two ED (Extra-low Dispersion) glass elements for sharp, high contrast images at all focal lengths.

Super Sonic wave Motor (SSM): The built-in Super Sonic wave Motor (SSM) gives you fast, smooth, quiet focusing.

Auto/Manual Focus: You can switch between AF (auto focus) and MF (manual focus) on the lens. The auto focus range can also be selected. The switch has three positions: Full (no distance limit--auto focus works in the entire range), 3m-infinity (AF works from 3 meters to infinity), and Manual Focus. To shoot in AF mode, you will need to set the focus mode to AF on the camera and the lens. To shoot in MF mode, you can set the lens or the camera to MF, or both. The focusing ring can be rotated until the subject is in focus.

Direct Manual Focus (DMF): The focusing ring can be rotated to set the correct DMF when the focus is locked in AF-A (automatic auto focus) or AF-S (single-shot auto focus).

Focus Hold Button: The lens has a Focus Hold button, which, when pressed and held, suspends the auto focus function and fixes the focus for shooting. If the camera has a custom function capability, the function of the Focus Hold button can be changed. The SAL70400G has three Focus Hold buttons.

Lens Hood: The lens includes a flower-shaped lens hood to reduce flare and ensure maximum image quality. It has a polarizing filter window which can be opened to allow the rotation of the polarizing filter (if one is attached) without having to remove the lens hood. The window should be closed before shooting. When not in use, the lens hood can be inverted and stored on the lens backwards. If using the camera's built-in flash, you will need to remove the lens hood to prevent blockage of the flash light.

Tripod Mount Collar: Because of its weight and size, the SAL70400G lens includes a tripod mount collar. The collar can be loosened to allow you to rotate the camera between vertical and horizontal positions while mounted. There are index marks at 90° intervals so you can adjust the camera position precisely. If desired, the collar can be totally removed.

Teleconverter Compatibility: The lens is compatible with the optional SAL14TC (1.4x) and SAL20TC (2x) teleconverters in MF mode only. The Auto Focus function on the camera does not work with teleconverters installed.
