I'm selling a BLACK Zeiss G Vario-Sonnar 35~70mm f/3.5-5.6 for Contax G2. Also adaptable to several digital cameras as you know.
The lens is in very fine condition, may have very small marks of use. But I could almost as new. The glass is clean, no scratches, no fungus.
Price: 600 Euros
If you have any question or would like some photos, please let me know.
