    Overview

    The Sigma AF 28-200 mm f/4-5.6 Zoom-Eta is a compact all-in-one zoom from the film era, offering versatility from wide-angle to telephoto in a single lens. It provides adequate sharpness for general use, with best results around f/5.6–f/8 in good light. Optical weaknesses include a slow variable aperture and lack of stabilization. Build quality is typical of its era, with plastic construction and smooth zoom/focus rings. It suits photographers seeking an affordable, vintage look for film or adapted mirrorless use, especially for travel and everyday shooting.
