The Jupiter-8 (ЮПИТЕР-8) is the Russian version of the German Carl Zeiss Sonnar f/2 (The f/1.5 Sonnar was cloned under the name Jupiter-3). It was released both in LTM (M39) and in Kiev (Contax) mount. The lens that I present is the Kiev-version.

There exist many minor variations of this lens. Production of the Jupiter-8 in Contax-mount was initiated soon after the war by KMZ, but production was moved to Arsenal (Kiev, Ukraine) and started there in 1954. This lens is the first Arsenal version and was made in 1955 (serial 5510986). This model was only made in the period 1954-1956 and was rebaptized Jupiter-8M from 1957 on.

Princelle lists this lens as A160; SovietCams has it listed as PT3560.

Aperture range: f/2-f/22
Minimum focussing distance: 0.9m
Aperture blades: 9

I am particularly fond of the Jupiter-8 for Kiev league... I obtained the adapter from my Hungarian friend Attila, another MF-lens aficionado. You can buy the adapter from his e-bay store. It is, by far, my favourite adapter.

A real-life example:

ISO400, f/2
