Film grain is random... i noticed that the fuji algorithm wasn't random as well. Honestly they're excellent at marketing (which is all the 'random film grain-like sensor' is) but seem to rush things into production. I hope the x pro 1 is different. Though the x100 has its place in my heart, Fuji is all show. The sensor itself, which is wonderful, is by sony. and the physical design of the camera is all fuji, that is to say they are responsible for difficult AF, poor menu layout, poor battery performance, poor manual focus, sluggish startup/read/write speeds, poor OVF/AF coupling, etc. But the size/sensor keep it up there as one of my favorite cameras despite the poor mechanics.
