The 180/5.5 Piesker Tele-Kalimar lens was recently acquired. It features a preset diaphragm with f/stops from f/5.5 to f/22. It focuses from infinity down to 8 feet.

For a 180mm lens, it is very compact in size measuring only 4 1/2 inches long without its shade. It is pictured with its proper caps and cylindrical tube.
