My auto exposure, scale focus, viewfinder Zeiss-Ikon Tenax is amazing. Its 50mm Tessar lens is phenomenal. An exceptional example of a seemingly mediocre 35mm camera which cost $3 at a thrift store in '95. Z-I had a service center in North Hollywood back then and the tech was overjoyed to put in on the testing bench and give it a thumbs up. Business may have been slowing for Z-I in those days but he was quite keen on the virtues of the Zeiss Tessar lens and didn't charge a cent for the service. Great guy, great company, great camera.
