Re: [APML] Carl Zeiss 300mm f/4 lens for 35mm or Pentax67 cameras?
I found it very disturbing to but a Contax with Zeiss lens, then find it was made in Japan, not in Germany, then found that the optics were pretty awful.
I recommend people to stay away from Zeiss till they go back and reestablish themselves in Germany
