Just posted: Our hands-on first look at the Fujifilm X100S. Fujifilm's update of its large sensor, fixed lens X100 adds significant upgrades, including a 16MP X-Trans CMOS sensor with on-chip phase detection AF, a higher resolution LCD display in its unique Hybrid optical/electronic viewfinder, and the company's latest user interface. But there's a whole host of smaller improvements too, which promise to iron out many of the X100's particular quirks. In our first look preview, we take a detailed look through what's changed compared to its predecessor.
