The Jupiter-8 (ЮПИТЕР-8) has quite a history. Many versions have been produced. Sometimes, the changes were limited to a cosmetic upgrade, but at other times, the lenses were redesigned (for instance, the redesign of Jupiter-8 to Jupiter-8M). The first Jupiter-8 lenses with Kiev/Contax mount were produced by KMZ (Krasnogorsk) when the Great Patriotic War had ended. Contax parts sacked from the Zeiss factories were donated to the Arsenal factory in Kiev and the production of Kiev-cameras was started in 1947. However, the first Arsenal-fabricated Jupiter-8 lenses date from 1954.
Three Arsenal Jupiter-8 versions are known (following SovietCams):
PT3560: first version (1954-1956), metal aperture ring (previously published on my blog)
PT3565: second version (1956-1957), black aperture ring
PT3570: third version (1957-1959), black aperture ring, without "No" serial prefix
It you look at the comparison images, you can notice some minor differences in the aperture settings scale.
Aperture range: f/2-f/22
Minimum focussing distance: 0.9m
Aperture blades: 9

The adapter is made from an original Kiev-camera. I bought it from my Hungarian friend Attila. You can buy the adapter from his e-bay store. It is, by far, my favourite adapter.
