    Overview

    The Sony 100-400mm f/4.5-5.6 GM OSS is a versatile telephoto zoom praised for excellent sharpness, especially at 400mm, fast and accurate autofocus, and high build quality with weather sealing. Weaknesses include noticeable distortion in raw files, a steep price of $2500, and zoom action that can feel stiff and sucks in air. It suits wildlife, sports, and landscape photographers seeking a compact, high-performance telephoto zoom.
