I'm just doing market research on the camera right now. - First of all, the firmware enabling this feature has not been released yet. Is this correct? - Secondly, when this mode is enable, the camera can do the recording and storing of the video internal? I did a quick calculation and 400 megabit comes out to be 50 mega-byte. The fastest uhs-1 (sdxc uhs-1 u3 v30) card can write at ~90 megabyte per second. - If my calculation is right, then what's the point of needing a uhs-ii class card? These uhs-ii card can write up to 150 megabyte per second based on official spec. (Bus Speed (Default Speed/ High Speed/ UHS) - SD Association) Thanks.
