    35–70mm · f/3.5

    Overview

    The Tamron 35-70 mm f/3.5 Adaptall-2 model 17A is a compact, moderately fast zoom with macro capability to 1:2.8 at 70mm. Optically, it performs well wide open and throughout the zoom range at distance, but close-up sharpness is poor even stopped down. Build quality is good with plastic construction that feels solid, and handling is nice with a prominent focus ring, though the aperture ring is stiff and narrow. It is lightweight (330g) and balances well on mirrorless bodies like the Sony A7. Best suited for budget-conscious photographers seeking a versatile walkaround lens for general use, but not for critical close-up work.
