    Overview

    The Sigma MF 80-200 mm f/3.5-4 MC High-Speed Zoom-Eta is a manual focus telephoto zoom for full-frame and APS-C, produced from 1980. It uses a push-pull zoom mechanism and has a built-in hood. Optical performance is decent but not outstanding; sharpness is good in the center but softens at the edges, especially at longer focal lengths. Chromatic aberration and flare can be issues. Build quality is solid for its era, with a metal barrel and smooth focus ring, though the push-pull action may feel loose over time. It suits users who want an affordable vintage zoom for film or adapted use, but modern alternatives offer better image quality and autofocus.
