Price history: is the newer one cheaper?
Low light & noise
EOS R5 Mark II
4.4 µm pixels
45 MP on a full frame sensor, ISO up to 51,200
α1 II
4.2 µm pixels
50.1 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
- DPReview studio scene ↗The same scene shot by each camera at the ISO you pick, side by side
