Our take on the Sony SAL-70300G

by Woody Sherman

When you're shooting outdoors, the world is your subject. That means you'll need a lens that can take you to where the opportunities are in a hurry, while maintaining the flexibility to handle a wide range of distances. That's why this Sony SAL 70-300mm f/4.5-5.6 G-Series lens is such a good choice for the front of your Sony Alpha camera. Its generous zoom range will take you from a perfect portrait length to a close-up shot of the next mountain ridgeline over from where you are.

Superb clarity awaits you as well, thanks to two extra-low dispersion glass elements and an acclaimed multi-element optical design. And the Super Sonic wave autofocus motor (SSM) does its job quickly, smoothly, and quietly, while keeping your subject crisply locked-in.

Overview: The Sony SAL70300G (70-300mm F4.5-5.6 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 105-450mm when used with APS-C format cameras.

Compatibility: The SAL70300G 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 F4.5-5.6 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.

Lens Hood: The lens includes a flower-shaped lens hood to reduce flare and ensure maximum image quality. 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.
