Sony 70-400mm F4-5.6 G SSM Lens Key Features

• Super Telephoto Zoom. This superb 70-400mm zoom lens is an excellent choice for a wide range of medium to long-distance telephoto applications. (35mm equivalent when used with APS-C format cameras: 105-600mm.)
• Uncommonly fast aperture. The f/4-5.6 aperture enables shooting at higher shutter speeds to freeze sports action.
• Superb flexibility. The 5.7x zoom range goes all the way from 70mm, suitable for portraits and other medium-angle shots, to a super-telephoto 400mm.
• G Series Optical Performance. 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.
• SSM (Super Sonic wave Motor). Powerful telephoto zoom lenses tend to have larger, heavier elements that are harder to drive in Auto Focus. Sony achieves fast, smooth, near-silent automatic focusing with the Super Sonic wave Motor. It delivers high torque, high speed and rapid start/stop response.
• ED (Extra-low Dispersion) glass. Newton showed that different colors bend at different angles when they pass through glass. In lenses, this causes the problem of chromatic aberration. Sony solves the problem with two ED (Extra-low Dispersion) glass elements. You get sharp, clear images with well defined colors.
• Superb Minimum Focusing Distance. With the ability to focus as closely as 5 feet (1.5m), this telephoto lens also lets you move in for dramatic shots of people, natural subjects and close-up details.
• 0.27x maximum magnification.
• In-Camera Image Stabilization. Works with the SteadyShot image stabilization built into Sony Alpha D-SLRs.
• Three Focus Hold Buttons. The lens enables to you firmly lock in focus for creative control. Focus range limiter can be set to speed auto-focus response. Focus Hold also enables image preview with the A900 D-SLR.
• Smooth Manual Focusing. An easy-grip focus ring on the lens barrel gives you a solid "hands-on" feel in manual focusing.
• Multi-Element Design. The SAL-70400G incorporates 18 elements in 12 groups for high optical precision from the center of the image all the way to the corners.
• Internal Focusing. Focus is accomplished by moving an internal element group, so focus is faster.
• 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. The lens features nine aperture blades.
• Auto Clutch. For reliable operation, the manual focus ring does not rotate in auto-focus mode.
• Works with Optional Teleconverters. Compatible with optional Sony SAL14TC (1.4x) which extends focal length to 560mm (35mm equivalent when used with APS-C format cameras: 840mm) and SAL20TC (2.0x) teleconverters which extends focal length to 800mm (35mm equivalent when used with APS-C format cameras: 1200mm). Teleconverters are compatible with manual focus only.
