Additional information:

The Tamron 70-150 mm f/ 3.5 Adaptall-2 model 20A  is a telephoto zoom lens with constant lens speed for 35 mm SLR cameras popular in the 1970-90s (via the interchangeable Adaptall-2 mount).

The lens features a push-pull design (focal length is changed by pushing or pulling the focus ring, and in so doing the lens length is changing). It is multicoated.  The lens is equipped with a built-in hood.

At a focal length of 70 mm it enables you to take 1:3 macro scale pictures.

As compared with the first variant (model 02А), the lens has been considerably redesigned and features improved optical characteristics.
