• Front side - M39x1 female thread

This adapter allows using lenses from old Russian ZENIT cameras on Canon EOS cameras with EF mount.

IMPORTANT NOTE: this adapter will NOT work with lenses from rangefinder cameras like Leica, FED, Zorki. They have same thread, but can not be used on (d)SLR cameras and will not focus to infinity even if fit physically.
