Early December will see the announced firmware update, which Olympus will use to improve the video capabilities of its current professional MicroFourThirds camera OM-D E-M1X as well as the E-M1 Mark III. They will then be able to output 4K/UHD (in 30p/25p/24p) and Cinema 4K (in 24p) as 12-bit RAW video signals via HDMI to the Atomos Ninja V HDR monitor/recorder for recording in ProRes RAW format. However, since the sensor resolution of these cameras is higher than 4K at 20MP, no real "raw" signal is recorded -- as with some others, such as the Sigma fp or the NIkon Z6. It remains to be seen how the conversion of the sensor data is done in the camera. As always, support will require an update to the latest Ninja V firmware.

But also the image stabilization for video recordings should be even better with the new firmware, because the algorithm has been revised. The E-M1X / E-M1 Mark III have a movable sensor for 5-axis image stabilization. In addition, a new focus display is to enable a quick check of the focus direction and the approximate focus position during manual focusing.
Firmware version 2.0 for the OM-D E-M1X and firmware version 1.2 for the E-M1 III will be released on December 3, 2020. Also for the E-M1 II and E-M5 III will be updated, but will only get the improved video stabilization and focus display.
