blp1664886145 Posted July 15, 2020 Share Posted July 15, 2020 It is a Komura 135mm f3.5 lens s/n 512345 which was part of a lot I bought a while ago. Last remaining mount to identify. I think it might be Praktika, but not sure Thank you in advance for any information Link to comment Share on other sites More sharing options...
John Farrell Posted July 15, 2020 Share Posted July 15, 2020 Exakta? Praktica cameras were produced in bayonet mount from 1979, and this lens would be older than that. Link to comment Share on other sites More sharing options...

steve_gallimore1 Posted July 15, 2020 Share Posted July 15, 2020 Some Komura lenses had a removable/interchangeable mount, sort of a precursor to T2/adaptall, look for 3 little grub screws behind the mount. Of course, that is of no help if you have no other Komura lenses. Link to comment Share on other sites More sharing options...
rodeo_joe1 Posted July 15, 2020 Share Posted July 15, 2020 The Exakta mount is tiny. Some clue as to its size would help identify it. Link to comment Share on other sites More sharing options...
