Tamron 28mm f/2.8 (CW-28) - Tamron Adaptall Mount

The Tamron 28mm f/2.8 (model CW-28) is a vintage wide-angle prime lens designed for the original Adaptall mount system. It offers a classic 75-degree angle of view, making it suitable for landscape, street, and architectural photography. Compact and lightweight, it was designed to be easily adapted to various 35mm SLR bodies of the 1970s. The optical design prioritises portability while maintaining decent centre sharpness. Potential buyers should examine the aperture blades for signs of oil or sluggishness, which can occur with age. SDS ensures the manual focus ring operates smoothly across the range without gritty resistance. As an older Adaptall lens, the mounting lugs should be checked for damage to ensure a light-tight fit with the required adapter. The front and rear glass elements are inspected for scratches and coating degradation.
