The Sony 70-400mm f/4-5.6 G2 Telephoto Zoom Lens is long-reaching portrait-length-to-telephoto zoom lens that is compatible with both full-frame and APS-C-sized image sensors. Its great zoom range is well benefitted by the inclusion of a high-performance focusing system that revolves around the Super Sonic wave Motor (SSM) for smooth, fast, and quiet AF performance. Benefitting quick shooting applications, this focusing motor utilizes piezoelectric elements that change shape and provide lens functionalities that include a large rotational distance at low speeds and quick start and stop response times. For further refinement of the focusing abilities, three focus hold buttons are available for locking-in focus positions and a focus range limiter can also be employed for greater focus response and subject tracking efficiency. When working with manual focus, an easy-grip focus ring provides increased tactility for more control and an auto clutch mechanism will also disable the manual focusing ring when working in AF modes.
The Sony G-series lenses are designed to provide optimal image sharpness and clarity as well as even peripheral illumination from edge to edge. Contributing to this enhanced image quality is the inclusion of two extra-low dispersion (ED) glass elements, which minimize chromatic aberrations throughout the zoom range and help to maintain true colors and image clarity. Additionally, a Nano AR Coating is also applied to lens elements to reduce lens flare, ghosting, and surface reflection in order to improve image contrast and light transmission.
