Price history: is the newer one cheaper?
Low light & noise
SL3-P
4.4 µm pixels
44.9 MP on a full frame sensor, ISO up to 200,000
Lumix S1R II
4.4 µm pixels
44.3 MP on a full frame sensor, ISO up to 51,200
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

Size, to scale
We don't have the maker's dimensions for the Leica SL3-P, so there's nothing to draw to scale.
