Low light & noise
Z8
4.3 µm pixels
45.7 MP on a full frame sensor, ISO up to 25,600
α7R VI
3.6 µm pixels
66.8 MP on a full frame sensor, ISO up to 32,000
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
