Does your copy lock into infinity on the Fed-2? Mine doesn't, but locks perfectly on the Zorki-5 that it came with.
The regular Industar 22 and 50 lenses won't go to infinity with a FED2, at least an older one, as the lens mount is too thin. It needs a version of the FED50 lens which has a different infinity lock.
Cheers,
