    50–500mm · f/4.5–6.3

    Overview

    The Sigma 50-500mm F4.5-6.3 DG OS HSM is a 10x superzoom offering extreme versatility from normal to super-telephoto, but optical quality degrades noticeably at longer focal lengths. Build quality is solid with smooth rings and effective optical stabilization, though the lens is heavy (about 4.1 lb) and large. Autofocus is generally fast but can hunt in low contrast. It suits photographers needing a single-lens solution for wildlife or travel, especially on APS-C bodies where it reaches 800mm equivalent.
