Excellent condition Contax Carl Zeiss Vario-Sonnar T* 28-70mm f/3.5-4.5 MMJ lens. 
Can be used with a variety of mounts other than Contax/Yashica (e.g., Sony Alpha NEX) 
with the right adapter or bayonet (cf. Novoflex, Fotodiox, Leitax, etc.)

Includes:
  • 1 x Contax 67mm L39 (UV) multi-coated filter.
  • 1 x Contax 67mm top (linear) polarizing filter with case.
  • Original front and rear lens caps.
  • Original documentation.
The optics (both lens and filters) are flawless, and the mechanicals are as smooth as when 
they were new. The best combination of German engineering and Japanese build quality.
