Overview

The Sigma 70mm F2.8 EX DG Macro offers excellent sharpness and 1:1 magnification, making it ideal for macro and portrait work. Build quality is robust with a metal barrel and smooth focus ring, though the AF motor is slow and noisy. The lens is compact and lightweight for its class. Weaknesses include no built-in motor on Nikon mounts, limiting AF compatibility. It suits photographers prioritizing optical quality and macro capability over fast autofocus.
