Overview

The Sony 70-400mm F4-5.6 G SSM II is a premium telephoto zoom lens praised for excellent sharpness across the zoom range, even at full aperture, with low chromatic aberration and minimal flare. DxOMark notes it is one of the sharpest super-zooms for wildlife, though sharpness at full aperture could be better. Build is robust, 'built like a tank', with fast SSM autofocus but occasional hunting in low contrast. It suits wildlife and sports photographers, especially on APS-C bodies where it reaches 105-600mm equivalent.
