thanks you"Pszczola "and"Madroz " but It is too expensive to buy . I found that most cameras and accessories are much expensive than that in my hometown . It cost only 120ZL for such an adapter . maybe I can buy contax lens such as Contax 50/1.4 or Contax 35/1.4 .or Voigtlander 125/2.5 here .
Can you recommand where I can but them in Warsaw ? and what is the probable price ?
