Tamron 80-210 F/3.8-4 Model 03A cutaway

Tamron 80-210mm F/3.8-4 Model 03A: This is a fairly lightweight and very nice handling zoom lens with average performance. Additional features include a built-in lens hood and continuous focusing into macro mode. This model 03A lens, introduced in 1979, was superceded in 1981 by the model 103A. The latter model 103A is more compact, doesn't have a built-in lens hood, and features a heavily revised revised optical design with much better off-axis optical performance. The photo at right (click on photo for a much larger version) shows a cutaway which nicely illustrates the internal complexity of zoom lenses which feature all metal construction.
