The X100S retains the classic styling of its predecessor the X100 but has been extensively re-worked inside, with a 16MP X-Trans sensor that includes on-chip phase-detection elements (a technology first utilized by Fujifilm), and a higher-resolution LCD in its Hybrid optical/electronic viewfinder. A faster 'EXR II' processor, along with the on-chip AF information help Fujifilm offer what it says is the world's fastest AF. The X100S backs-up its rangefinder-esque looks with a digital split-image manual focus system, allowing fast manual focusing. Image quality is excellent, and almost all of the operational quirks that dogged the X100 have been fixed in its replacement. The X100S is definitely one of our favorite cameras of the year.
