Noise
At low-sensitivity settings from ISO 100 to ISO 400, the LX100 II delivers impressive image quality with no visible noise and crisply defined fine detail. It’s only at ISO 1600 that noise starts to have a clearly detrimental impact, obscuring fine low-contrast detail, but you’ll only really see this when zooming into your image files or making large prints. By ISO 6400 colour saturation is starting to suffer and detail in the darker tones has all-but-disappeared, yet images are still perfectly usable at smaller viewing sizes. However, quality at ISO 12,800 is distinctly marginal, with lots of noise and poor colour. I’d avoid using ISO 25,600 completely.
