The Fuji X100S takes the highly-acclaimed Finepix X100 to the next level with an all-new 16 megapixels X-Trans II CMOS sensor and faster EXR CMOS processor. Bring the resolution up to 16 megapixels and dropping the anti-alias filter to maximize resolution, this model adds built-in phase-detect autofocus to provide a hybrid focusing system. It also improves upon the unique hybrid viewfinder by upgrading the EVF component to 2.4 megapixels while retaining a large bright-line OVF mode.
