Overview

The Tamron-F 28mm f/2.8 (I) is a compact, all-metal lens from the Adapt-A-Matic range (1969-1971), praised for its sturdy build. Optically, it delivers sharp, colorful images with good bokeh, though a five-blade aperture. Weaknesses include a loose aperture ring on older copies and heavy weight due to steel construction. It suits photographers seeking a vintage wide-angle for manual focus on DSLRs with an adapter, but autofocus is limited to certain Nikon bodies.
