    Overview

    The Tamron 70-220 mm f/3.8 Adaptall model Z-220 is a well-built but outdated zoom from the 1960s. Its build quality is superb, with excellent fit and finish. However, it is extremely large and heavy, with a tripod mount reflecting its size. Optically, it is adequate but not sharp at f/4, with strong red fringing; performance improves when stopped down. It suits collectors of vintage Tamron Adaptamatics or those who prioritize build over modern optical performance.
