The Sony 70-200mm f/2.8 G SSM II Lens is a versatile zoom lens covering portrait-length to telephoto perspectives and featuring a constant f/2.8 maximum aperture for enhanced low-light shooting and focus control throughout the zoom range. A Super Sonic Wave Motor (SSM) focusing mechanism provides fast, smooth, and quiet focusing performance with enhanced tracking capabilities that are well-suited to photographing quickly moving subjects. Also helping to increase focusing speeds is the integration of a Focus Range Limiter, which enables you to set pre-defined limits for the lens to focus within for faster response times. Additionally, when paired with Sony A-mount cameras, in-body image stabilization renders this lens stabilized and supports the use of longer shutter speeds with a reduction in appearance of camera shake.
The optical design employs two extra-low dispersion elements to minimize chromatic aberrations throughout the zoom range as well as heighten image clarity and overall sharpness. A Nano AR (anti-reflective) coating has also been applied to lens elements in order to reduce lens flare and ghosting for more contrast-rich imagery and high color neutrality.
