January 2008 - pictures shot with a PENTAX K20D and comparison with K10D:
Most pictures below are converted from DNG files, showing maximum possible noise (both brightness and color noise corrections have been zeroed, except two pictures as reported). Then, be aware that they don't have unsharp mask applied: please apply it at your leisure. Pictures at 3200 and 6400 ISO have been shot handheld and full aperture or so (hence not everything is in focus) either indoor with tungsten lighting or outdoor at night.
