Sensor performance comparable to full-frame output

Featuring FUJIFILM’s newly-developed 16.3 megapixel APS-C X-Trans CMOS II sensor with a unique, highly randomised, colour filter arrangement

Large APS-C sized X-Trans CMOS II sensor

Thanks to the lack of optical low pass filter(OLPF) and a new, unique pixel array, this sensor delivers a resolution to rival a full-frame camera. And with the addition of phase detection technology, there's also a huge leap in Auto Focus speed.

Leading the way to the ultimate image quality.

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 optimisation of every aspect of its processing circuitry. The enhanced image quality produced by the powerful EXR Processor II.

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

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). These filters are typically used in conventional systems to inhibit moiré, but they also reduce resolution.
The X-Trans CMOS II's pixel array lets the sensor capture unfiltered light from the lens, achieving an unprecedented level of resolution. In addition, utilising the enhanced performance of the EXR Processor II, Lens Modulation Optimiser (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

In the X-Trans CMOS II sensor, the optimised 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.
