I recently bought, second-hand and for a few euros, the following:
- adapter Exakta to Sony e-mount
- an Exakta 100-500mm 1:5.6-8 MC Macro lens, made in Japan
Strangely, the lens does not fit on the adapter.
Which kind of adapter do I need? I don't find any indication of the lens mount.
Inner diameters of the respective mounts:
- lens: 38 mm
- adapter: 37.5 mm
