My first DLSR ever was an E-510, which I think almost wore out. My second was an E-M10 which was a worthy upgrade but not a particular revelation. The E-M1.2 is insanely better than any camera I have ever used. And I have only begun to dig into the settings to configure it. I am really intrigued by the High Res Mode, HDR and anticipatory still buffering.
As to Affinity RAW support. I am surprised that the E-M1.2 isn't listed. Maybe they use an open source profile repository and don't know themselves. As with Affinity Photo, I am suspicious of Photo's E-M1.2 RAW support. Nowhere does Apple show E-M1.2 RAW support as near as I can determine.
The concern is that an app will somehow figure out how to render a file and even acknowledge the camera from which the file came, but not be using a profile that is correct and/or to have missing features. Or not. I just don't know. Support of a major new camera would seem to be something you'd want to announce. Just sayin'
