Low light & noise
5.9 µm pixels
24.6 MP on a full frame sensor, ISO up to 102,400
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
- DPReview studio scene ↗The same scene shot by each camera at the ISO you pick, side by side
- DPReview reviews ↗Full reviews with high-ISO samples
- Low-light video tests ↗Real-world high-ISO footage on YouTube
How it stacks up
- 446 g — lighter than 96% of the full frame mirrorless cameras we list
- 24.6 MP — more resolution than 55% of the full frame mirrorless cameras we list
