Having higher pixel densities just reduces ISO performance.
No it doesn't.
Yes it does.
Someday someone needs to explain to me why this myth persists after a decade of things going the other way despite similar basic sensor performance (QE).
It's no myth, it's physics. Did you ever ask yourself why the ISO-Monster A7S has lesser Pixel (12MP) and the 5DS with 53MP looses ISO against the old Model (ISO6400)?
The A7S has a better sensor, not just larger pixels.
The 5DS has the same pixel size as the 7DII, which is limited to ISO 16,000 bases, 51,200 extended. The fact that the 5DS is limited the way it is, despite the larger sensor (which gives it an inherent 1 1/3 stop advantage), proves that this is just another Canon artificial crippling exercise.
