Vintage Vivitar 135mm Telephoto Lens

Vintage Vivitar 135mm Telephoto Lens. Excellent vintage condition! A 135mm M42 mount lens with an auto/manual switch and a f/2.8 to f/22 aperture range. There is an in-built lens hood which slides over the front element when required, although on my copy this is so loose that it won’t keep in place if the lens is pointed upwards. The aperture has 6 blades and operates quite smoothly in half stop clicks apart from the final one-stop click from f/16 to f/22. The focusing ring is also smooth in operation, and is nicely damped. It is certainly easier to turn than the takumar 135 f/3.5, which if anything I find a bit too stiff. According to the focusing scale, the closest focusing distance is about 5 feet, so this would not be a natural choice for macro unless you use an extension tube or close focus attachment lens.
