    70–150mm · f/3.5

    Overview

    The Tamron 70-150mm f/3.5 Adaptall (model 02A) is an early two-touch zoom from 1979, but its optical quality is lackluster, described as 'one of the least interesting Adaptall 2 lenses'. It is heavier (585g) than its successor, the 20A, which has a better reputation for image quality. Build is solid but dated; the constant f/3.5 aperture is a minor advantage over the 20A's actual f/4. This lens suits collectors or those curious about early Adaptall designs, but most users should seek the later 20A model instead.
