Our Verdict
Olympus OM-D E-M1 Mark III
Olympus OM-D E-M10 Mark IV
The Olympus OM-D E-M1 Mark III sits above the Olympus OM-D E-M10 Mark IV in Olympus's camera lineup. The E-M1 III is an enthusiast-grade camera with a weather-sealed construction that feels sturdier and more comfortable to shoot with than the entry-level E-M10 Mark IV. Though they use similar sensors, the E-M1 III has a more advanced processor that gives it better RAW noise handling at higher ISOs. It also has a more advanced hybrid autofocus system that gives it significantly better AF performance. However, it's a lot bulkier and pricier than the E-M10 IV.
