Additional information:
The Tamron SP 70-210 mm f/ 3.5 Adaptall-2 model 19AH is a telephoto zoom lens 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). Due to design features the lens extends on zooming, as the focus ring moves forward. For the same reason an additional hood is attached to the focus ring, and not to the lens barrel.
The lens is multicoated. At a focal length of 210 mm it enables you to take 1:2.66 macro scale pictures.
