My first SLR was a rebadged Zenit -- the Cosmorex SE. I loved that camera and shot quite a bit of film with it.
I later got rid of it.
Years later, I bought another for $10 or so and was surprised how crude it now felt.
I remember that when I bought the Cosmorex back around 1974 or so, there were some Kodak Retinas in the case. But I had my heart set on a new camera, so I had to have the Cosmorex.
