Price history: is the newer one cheaper?
Low light & noise
ONE RS 1-Inch 360 Edition
2.4 µm pixels
21 MP on a 1" sensor, ISO up to 3,200
Theta Z1
2.2 µm pixels
23 MP on a 1" 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:
- Photons to Photos: dynamic range vs ISO ↗Photographic dynamic range measured at every ISO, bodies on one chart
- Photons to Photos: noise vs ISO ↗Read noise at every ISO from lab tests: lower is cleaner in the shadows
