The OM-D E-M10 Mark III takes a full-size SD, SDHC or SDXC card—not microSD without an adapter. Its 4K quick guide recommends UHS-I U3 or higher; the camera’s UHS-I workflow does not gain recording speed from a costly UHS-II card. Format a new card in the camera and choose capacity for the actual RAW, JPEG and video workload.
