Featuring Fujifilm's bespoke pixel array, the FUJIFILM X20 captures high quality images with its large 2/3-inch X-Trans CMOS II sensor. And you'll be able to enjoy high-speed continuous photography and Full HD movie shooting thanks to the high performance CMOS element of the sensor.
Originally developed by FUJIFILM for the FUJIFILM X20, the 2/3-inch X-Trans CMOS II sensor inherits the same architecture and features of the high performance sensor found in the acclaimed FUJIFILM X-Pro1 flagship model. Adoption of BSI (backside illumination) technology enables the successful incorporation of phase detection pixels into the array without affecting sensitivity performance- the key to FUJIFILM X20's high-speed AF.
X-Trans CMOS II adopts an original color filter array with a highly random pattern, eliminating the need for an optical low-pass filter (OLPF), which is used in conventional systems to inhibit moiré at the expense of resolution. This lets the sensor directly capture the high resolution performance of the FUJIFILM X20 lens. Also exploiting 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.

Optimization of the X-Trans CMOS II sensor reduces noise by over 30% for an improved S/N ratio. The quality of the clean signal is further enhanced by the new EXR Processor II. 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 color differential to suppress chromatic blur, resulting in image quality far beyond its sensor size.
