Does this work for lenses which have the Exakta Mount? In particular Zeiss Jena vintage lenses. Thanks. - Paul
Asked by: Paul
No, the Simmod M42 Lens to Canon EF Camera Conversion Mount will not work on Exacta Mounts.  The M42 is designed only to be screwed onto an M42 native lens, not any other form.
