Leica is no stranger to expensive cameras and lenses. For example, last October, a Leica 0-series camera from 1923 sold at auction for about $3.7 million. However, not all Leica equipment worth millions is anywhere near that old. Enter the Leica Apo-Telyt-R 1600mm f/5.6 super-telephoto (or super-super-telephoto) prime lens worth $2 million.
