28–200mm · f/4–5.6
The Sigma 28-200mm f/3.5-5.6 is a vintage superzoom covering wide-angle to telephoto, praised for its compact size and versatility. Optically, it performs best at f/8–f/11, offering character rather than clinical sharpness. Weaknesses include softness at extremes and distortion at wide-angle. Build is solid with a non-rotating front barrel for easy filter use and a zoom lock to prevent creep. It suits photographers wanting an all-in-one travel lens for film or adapted mirrorless use.
