Tamron Adaptall-2 75-250mm F/3.8-4.5 Model 104A Lens

Tamron 75-250mm F/3.8-4.5 Model 104A: This is a fairly lightweight and very nice handling zoom lens with above average performance. Additional features include a built-in lens hood and continuous focusing into macro mode. This lens, introduced in 1981, replaces the earlier model 04A with a heavily revised optical design. Note that this lens, cosmetically, is very similar in appearance to the earlier model 04A lens. It is very hard to tell these two lens versions apart unless you look at the model number engraved on the lens.
