I offer a Pentax 6x7 Super-Multi-Coated TAKUMAR 200mm f/4.0 lens for sale. The lens is in good condition and works flawless. It is a joy to use in the field, esp. with the extension tubes for close-up work.
Asking price is 170EUR, I am located in Germany but will ship to EU countries around Germany as well.
If you are interested in the extension tubes as well, they are yours for an asking price of 80EUR:
