For anyone interested, someone finally pointed me to a video showing the 1.6x crop mode footage. To me it looks very sharp and detailed. It is at around the 2:14 minute mark. If you look at the regular 4k mode before it there is a big difference in the pixelation of the street lights. Canon's heat sheet claims this mode does not overheat. So unlike the R you get IBIS and 10 bit internal, and maybe a little bit better autofocus in this mode. Not ideal for the price, but at least there
