I’ve developed a bit of a fondness for these vintage lenses. Great build quality, unique rendering, Zeiss “3D Pop”, and price, are a few of the reasons I reach for one of these lenses 9 times out of 10. I’m putting together this website in order to provide specific information on a variety of Carl Zeiss lenses made for CONTAX in the C/Y mount. New mirrorless systems from Nikon, Sony, and Canon, have made adapting these vintage lenses effortless. I hope you find the site enjoyable and informational.
