Advanced technology transfers the power of the lens into true-to-life photos.

X-Trans CMOS II incorporates an original color filter array with a highly random pattern, eliminating the need for an optical low-pass filter (OLPF). These 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, utilizing 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.

Setting new standards in low noise performance
X-Trans CMOS II Sensor & EXR Processor II

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 color differential to suppress chromatic blur, resulting in image quality far beyond its sensor size.
