Collector Notes:

Produced from 1979 to 1992, the 02B is part of Tamron’s legendary Adaptall-2 system, allowing photographers to swap mounts across brands. The f/2.5 aperture offers a slight edge in brightness over standard f/2.8 lenses, and the BBAR coating adds character with subtle flare and starbursts when stopped down. It’s a favorite among vintage lens enthusiasts for its portability, build quality, and close-focus capability.
