    Overview

    The Tamron 28-70mm f/3.5-4.5 Adaptall-2 model 44A is a versatile zoom lens with interchangeable mounts, praised for its adaptability. Optically, it offers good contrast and color, with sharpness best from 50-70mm at f/5.6-11, but soft at 28mm wide open. The 62mm filter version is preferred over the inferior 52mm variant. Build quality is acceptable, though the zoom ring feels less durable than the focus ring. It suits budget-conscious photographers needing a compact, all-around lens for film or casual digital use, especially with fast film.
