    Overview

    The Tamron 75-250 mm f/3.8-4.5 Adaptall-2 model 104A is a lightweight, value telephoto zoom with good sharpness, especially at 200mm, and pleasant color rendition. Its manual focusing ring is praised for being smooth and precise. Weaknesses include purple fringing in high-contrast scenes and a shallow internal lens hood that is not very effective. Build is solid but requires an Adaptall-2 adapter. It suits budget-conscious photographers seeking a compact, manual-focus telezoom for daylight use, though a 2x teleconverter degrades image quality and light.
