OM System OM-1 Series
OM System's professional Micro Four Thirds flagship.
The OM-1 line is the pinnacle of the OM System range — a weather-sealed, pro-grade MFT body built for demanding conditions. The original OM-1 introduced a stacked BSI sensor and subject detection AF; the OM-1 Mark II refined the autofocus further and added a higher-resolution EVF.
