g1xmk2 RAW noise performance
I find ISO640 to be the sweet spot on the mk2. Its really just about as good as ISO400.
This camera will be used by me to get many shots at f2.5 ISO640. Is it DSLR quality? Arguably not. Is it close enough for this photographer/dad not to plunge into the DSLR world? Absolutely.
The DPR noise comparisons sort of lose the 640 setting.
