Macro Takumar 50mm f4

The Macro Takumar 50mm F4 is one of the best if not the best macro lens ever made, and if you look for it online, with a lil chance you could find it for less than 100 $ ... actually i found mine for 5 $ :) The colors, the sharpness and the build quality of this lens make it the best macro lens to get in a vintage lens collection.
