Low light & noise
EOS R6 Mark III
5.2 µm pixels
32.5 MP on a full frame sensor, ISO up to 64,000
Z6III
5.9 µm pixels
24.5 MP on a full frame sensor, ISO up to 64,000
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
- DPReview studio scene ↗The same scene shot by each camera at the ISO you pick, side by side

- Low-light video tests ↗Real-world high-ISO footage on YouTube
