Duplicate Jupiter-11 listing — same Soviet 135mm f/4 M39 as ID 4563.
The Jupiter 11 M39 135mm f/4 is a duplicate listing of the Soviet telephoto described under ID 4563. Same lens — Soviet-era 135mm f/4 in M39 screw mount based on Zeiss design. Same optical quality, same M39 adaptation capability, same Soviet build characteristics. Do not purchase both listings.
Same optical quality as ID 4563. Soviet manufacture. f/4 slow. M39 mount. Based on pre-war Zeiss design. Functional but basic. The M39 adaptation to mirrorless is the sole practical utility. Identical to the other listing in every respect.
M39 mount. Same as ID 4563. Same specifications. Do not purchase both. The Jupiter 11 is one of the most common Soviet lenses — many examples exist. Check for smooth focus — Soviet lenses often need servicing.
Duplicate of ID 4563. Same lens. Do not purchase both. Very cheap. M39 adapts to mirrorless. Soviet quality. Only if one listing is cheaper than the other.
