Zeiss Ikon Contaflex lens 4.0 35mm Pro Tessar from Carl Zeiss on Sony E-Mount - A7rIV

This is the second video in my series about the Zeiss Ikon Contaflex Pro-Tessar set lenses from Carl Zeiss, which I have adapted to the Sony E bayonet.
In today's video I will show you the mechanical and optical quality of the Zeiss Ikon Contaflex 4.0/35mm Pro-Tessar from Carl Zeiss, which I used on a Sony A7rIV.
If you want to know more about the adapter and the general use of these lenses on the E-mount, check out my first video in this series.
