On my list of cameras I’ve always wanted, a vintage Contax rangefinder has been near the top. The post-war Contax rangefinders (IIa and IIIa models) are wonderful precision mechanisms, and I was lucky sometime ago to acquire a IIIa body at a reasonable price, but I still needed a lens. I had good luck with the Russian Jupiter 8 on my Leica IIIb, so I rolled the dice again and go the same lens in the Contax mount, very inexpensively. I just got the first roll developed, and I am again very happy with the sharpness of this lens!
