Price history: is the newer one cheaper?
Low light & noise
Osmo Action 4
2.6 µm pixels
10 MP on a 1/1.3" sensor, ISO up to 12,800
Ace Pro
1.2 µm pixels
48 MP on a 1/1.3" sensor, ISO up to 6,400
Bigger pixels gather more light each, so they tend to show less noise at high ISO, but sensor design matters as much. For real noise at ISO 6400, these sites measure it:
