Today Canon announced their new R5c video focused camera version (specs at BHphoto and Adorama). This might be considered an official competitor of the Sony A1 and you can find a full R5c vs A1 spec comparison on that special BH page. On the pro side this camera shoots 8k60p but on the downsides it doens’t have IBIS, a huge cooling vent and only a micro Hdmi.
