Sony RX1 ISO-range test samples (JPEG, RAW) at FN
A new Cameraholic Digest is coming within a couple of hours, but until then, you have a pixel-peeping assignment: Focus Numerique has published their Sony RX1 ISO-range test-samples, which are available both in JPEG and RAW. You can get to the full-size JPEG files by clicking on the crops. You can get to the full-size RAW files by clicking on the ISO numbers (50-100-200-400-etc) right below the last of the crops. They are the .ARW files.
Spoiler alert: .ARW is an anagram of RAW :)
Availability-wise, the Sony RX1 is in a state of pre-order, with Amazon offering a blanket December-2012 release estimate, Adorama offering a mid-December-2012 estimate and B&H Photo offering a December-14-2012 estimate. Please note however that estimates are only estimates and estimates change over time!
