Front lens cap for Jupiter-11 4/135.

The Jupiter-11 F4 is a fantastic lens. In combination with a M42 to Canon-EF adapter you can use it with modern DSLR- or film cameras like the Canon, Blackmagic or RED.

Since this camera stuff is super expencive, I decided to buy some sweet russian lenses on ebay. The lens designs of that UDSSR glases are captured by the russians from the german manufactuer ZEISS after WW2 as spoils of war. So the lens quality is nearly as good as the old Zeiss ones.
But cheep as beans! They will go for abou
