28mm · f/2.8
The Tamron-F 28mm f/2.8 (II) is a compact, all-metal lens from the Adapt-A-Matic range (1969-1971), built to a high standard comparable to Nikon/Canon/Zeiss. Optically, it delivers crisp, colorful images with vibrant colors, good sharpness, and pleasant bokeh at f/2.8; group shots are sharp at f/4-f/5.6. Weaknesses include a loose aperture ring due to age and no autofocus on entry-level Nikon bodies. It suits users who appreciate vintage build quality and manual focus, especially for portraits and group shots.
