The Nikon Nikkor 50-135 mm f/ 3.5 Ai-S is a constant lens speed zoom for Nikon F cameras.
The lens is based on a push-pull scheme (focal length is changed by pushing or pulling the focus ring, the lens length is changing at the same time).
The lens body is all-metal.
Design feature - the front lens does not rotate (for a convenient use of a polarizer).
Macro capabilities: focal length - 50 mm, minimum focusing distance - 0.6 m, scale - 1:3.8
The lens may be considered rare.
