    Overview

    The Tamron 70-150mm f/3.5 Adaptall-2 model 20A is a compact, lightweight telephoto zoom with good color rendition and decent sharpness, especially in the Adaptall-2 version (pdeley). It offers close-focus capability and is well-suited for casual use on mirrorless cameras like the Sony NEX (k9tales). However, it is less common than longer zooms like the 70-210mm, and its optical performance is not exceptional, with the original Adaptall version being less sharp (pdeley). Build quality is typical of the era, and it is best for those wanting a compact, affordable vintage zoom for general photography (Miranda F).
