The Fujifilm X100s offers you ultimate image quality. Eliminating the optical low pass filter and employing the same original pixel array as the X-Pro1 are the keys to resolution rivaling a full-size sensor.
OLPF-less architecture and the original pixel array are the keys to resolution rivaling a full-size sensor. With the unique integration of phase detection pixels in the array, the X100S takes a dramatic leap in AF speed.
The extreme resolution of FUJIFILM's bespoke APS-C 16M X-Trans CMOS II sensor with OLPF-less architecture, the clarity of the signal achieved by the optimization of every aspect of its processing circuitry, and the enhanced image quality produced by the powerful EXR Processor II take the X100S to the next level of excellence.
X-Trans CMOS II incorporates an original colour filter array with a highly random pattern, eliminating the need for an optical low-pass filter (OLPF). OLPF filters are used in conventional systems to inhibit moiré at the expense of resolution. The X-Trans CMOS II array lets the sensor capture unfiltered light from the lens, achieving an unprecedented level of resolution. In addition, using the enhanced performance of the EXR Processor II, Lens Modulation Optimizer (LMO) factors are calculated to compensate for aberrations and diffraction blur that occur when light passes through the lens and then are applied to produce images with amazing sharpness.

In the X-Trans CMOS II sensor, the optimized circuits elevate the S/N ratio and produce a clean signal that is enhanced by the powerful new EXR Processor II for a further increase in image quality. The original signal processing of the X-Trans array, featuring advanced noise separation technology, combines with a newly developed noise reduction process that exploits the colour differential to suppress chromatic blur, resulting in image quality far beyond its sensor size.
