Though I can squeeze out 16,000 ISO from my Canon R8 using it's R6ii sensor,
it is amazing how well this Sony does for being 10 years older and double the resolution.
Sometimes you can hide the noise in the pixels for the sheer amount of them.
Also, the Sony is a joy to use, whereas the R8 with it's fat flip out screen,
small grip, and plasticky feel - not so much.
