Overview

The Tamron 28mm f/2.8 Adaptall (model CW-28) is a compact, all-metal lens praised for excellent handling and solid build. Optically, it delivers crisp, colorful images with good sharpness at f/4–f/5.6 and pleasing bokeh at f/2.8. Weaknesses include a loose aperture ring on older samples and manual focus that can be challenging in dim light. It suits film shooters or digital users with Adaptall adapters who want a durable, affordable wide-angle prime.
