Crop-Frame E-Mount. The Sony E 70-350mm f/4.5-6.3 G OSS is designed for crop-frame Sony E-mount cameras, on which it provides a 105-525mm equivalent focal length.

Pro-Grade Telephoto Zoom. The E 70-350mm f/4.5-6.3 G OSS is a telephoto zoom that’s great for sports photographers, wildlife photographers, landscape photographers, and anyone who’s looking for some extra reach. The seven-blade diaphragm helps create smooth bokeh when you’re using selective-focus techniques.

Image Stabilization. An Optical SteadyShot image-stabilization system minimizes the appearance of camera shake at all focal lengths, giving you sharp images even when you’re shooting hand-held at lower shutter speeds. The SteadyShot system will work with select cameras’ built-in sensor-shift image stabilization for even more effective blur control.

XD Linear Motor Autofocus System. This system provides fast, nearly silent, and highly accurate autofocus performance that’s great for still and video use. A dedicated focus hold button and AF/MF switch help to tailor focusing to your shooting needs.

Advanced Optics. The E 70-350mm f/4 G OSS’s thirteen-group/nineteen-element design includes one aspherical element and three extra-low dispersion elements to minimize chromatic aberrations, and to produce clear, high-contrast images.
