    Overview

    The Tamron 70-150mm f/3.5 Adaptall (model CZ-150) is a compact manual-focus zoom praised for its small size and 49mm filter thread. It offers good close-up capability down to 1:3, extendable to 1:1.5 with a 2x teleconverter. Sharpness is reasonable but not class-leading; it cannot match the optical quality of a DA* 50-135, though it is preferred for hiking and street photography due to its lighter weight. It is easier to use on cameras with image stabilization, like Pentax, than on unstabilized bodies. Best suited for budget-conscious shooters seeking a portable telezoom.
