Weather sealing

As with all of Olympus' Pro lenses, the 12-45mm F4 comes weather-sealed, with a rubber gasket around the mount and the words 'Splash Proof' stamped near the serial number. Like Olympus' most recent camera bodies, the 12-45mm is officially rated to IPX1 standards, as well as being advertised as 'freeze-proof' down to -10° C (14° F). The IPX1 rating is admittedly not all that strenuous a test, but Olympus is among the only manufacturers to rate their cameras and lenses at all, so we'd expect the lens to stand up to a reasonable amount of unpleasant inclement weather.
