Telephoto Zoom: This The 2.8x zoom range goes all the way from 70mm, suitable range of mediumto lofor portraits and other medium-angle shots, to a telephoto sed with APS-C format200mmras: 105-300mm.)
Uncommonly fast aperture: The fast f/2.8 aperture enables shooting at much higher shutter speeds to freezeaction.
Superb flexibility: The 2.8x zoom range goes all the way from 70mm, suitable for portraits and othermedium-angle shots, to a telephoto 200mm
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): Designed for fast, smooth, silent automatic focusing, this unique technology achieves high torque at low speed with rapid start/stop response. It operates through the ability of a piezoelectric device to reshape itself quickly when voltage is applied.
ED (Extra-low Dispersion): Two ED (Extra-low Dispersion) glass elements minimize chromatic aberration for sharp, clear images with well defined colors.
Superb Minimum Focusing Distance: With the ability to focus as closely as 3.9 feet (1.2m), this telephoto lens also lets you move in for dramatic shots of people, natural subjects and close-up details.
In-Camera Image Stabilization: Works with the SteadyShot INSIDE. image stabilization built into Sony a DSLRs.
Focus Range Limiter: Used when you need the quickest possible autofocus response within a certain focal range. The lens will only autofocus within the set range eliminating AF atfocal lengths outside.
Multi-Element Design: The SAL70200G incorporates 19 elements in 16 groups for high optical precision from the center of the image all the way to the corners.
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.
Works with Optional Teleconverters: Compatible with optional Sony SAL14TC (1.4x) which extends focal length to 280mm(35mm equivalent when used with APS-C format cameras: 420mm) and SAL20TC (2.0x) teleconverters which extends focal length to 400mm (35mm equivalent when used with APS-C format cameras: 6900mm). Teleconverters are manual focus only
