    Overview

    The Tamron SP 24-48mm f/3.5-3.8 Adaptall-2 model 13A is a compact, all-metal wide-to-normal zoom with smooth manual focus and versatile Adaptall-2 mount. Optically, it delivers good sharpness and contrast, especially at the wide end, where it can outperform the Canon 24-105mm f/4 L. Weaknesses include a slow aperture, no filter thread on the front, and significant flare without the rare hood. Build is solid but the aperture ring feels flimsy. It suits full-frame users seeking a characterful, affordable wide zoom for video or stills.
