Overview

The Sony 70-400mm F4-5.6 G SSM is a professional-grade telephoto zoom lens offering excellent sharpness across the zoom range, even at full aperture. It has low chromatic aberration and minimal vignetting. Build quality is superb with a metal body, though it lacks weather sealing. The SSM autofocus is reasonably fast but may struggle in low contrast. It is well-suited for sports and wildlife photography. Weaknesses include slightly soft full-aperture sharpness and a high price.
