It looks like you are right Bernard - it's just a gizmo to get the lens cap

NB Bernard, do *not* assume that the hood above will fit your lens! Anyway,
that seller is strictly US only.

The lens hood for the Zuiko 18mm is the 49mm to 72 mm adapter. It is very
shallow. It sounds like the ring could be the lens hood. -jeff
