Overview

The Tamron 21mm f/4.5 Adapt-A-Matic is a pre-computer era lens with a warm vintage rendering. Its build is almost entirely metal and built to last. Optically, it is a pre-computer era design, so it may lack modern sharpness and contrast. The Adaptamatic system uses a breech-lock mount, which is physically incompatible with later Adaptall bayonet mounts. Handling is fully manual, making it suitable for mirrorless shooters who want a tank-like build and classic optics. It suits vintage enthusiasts and those seeking a unique rendering.
