The E-1 was usually sold bundled with a splash proof Zuiko Digital 14–54 mm 1:2.8–3.5 zoom lens.

Olympus initially gave away free adapters to connect OM lenses to the new Four Thirds System mount.

This adapter allowed a wide range of OM lenses to be used with the new Olympus DSLRs.

The adapter is no longer given away for free, but is still available for purchase from authorised Olympus resellers.
