I published our Fujifilm X100S studio sample photos last week and they are beautiful. There's only one other APS-C sensor out right now (Nikon D7100) that I think is comparable and I'm not sure it has the subtlety and dynamic range that the X100S's X-Trans CMOS II sensor has. Since Fujifilm's interchangeable lens X-Series cameras all use the original X-Trans sensor and processing, the X100S is a peak into what we can expect from the next generation - and it is good. Take a look at the studio tests to see for yourself how they've improved on the original X-Trans sensor:

Do we have any X100, X100S or X-Series mirrorless camera owners here? What do you think of the X100S image quality?
