OM System OM-5 Series

The rugged Micro Four Thirds adventure camera — across two generations.

The E-M5 III (under the Olympus name) and its successor the OM-5 represent the more compact, weather-sealed option in the OM System lineup. Both are built for outdoor and travel photography, with strong IBIS and comprehensive weather sealing in a lighter body than the OM-1.
