The Tamron 35-135 mm f/ 3.5-4.5 Adaptall-2 model 40A is a kit zoom lens for 35 mm SLR cameras popular in the 1970-90s (via the interchangeable Adaptall-2 mount).
The lens is based on a push-pull scheme (focal length is changed by pushing or pulling the focus ring, in so doing the lens length is changing). It is multicoated.
At a focal length of 35 mm the Tamron 35-135mm f/3.5-4.5 Adaptall-2 model 40A makes it possible to take 1:4 macro scale pictures, and in so doing thу minimum focusing distance is reduced to 0.26 m.
As compared with the first variant (model 22А), this lens has a smaller filter diameter. The optical characteristics of both variants are the same.
