Very nice quality for I.S.O. 12,800 - good rich color good clarity and not much grain (noise) - very well done for micro four thirds. Would like more dynamic range (highlights and shadows) in direct sunlit lower I.S.O. though, highlights clip a little bit too soon for me and shadows block up too fast in micro four thirds in general. Hopefully these areas will continue to be improved (as they have been) by micro four thirds manufacturers.
