X-Trans CMOS

Continuous Evolution on Resolution
and Color Reproduction

X-Trans CMOS *1 sensor developed by Fujifilm.
Nurtured the idea from film technology,
X-Trans controls moiré while achieving high resolution without the use of a low-pass filter.

X-Trans CMOS 4

4th generation sensor for the X series — A Back-illuminated sensor

Boasting a resolution of 26.1MP, the sensor uses a unique color filter array, synonymous to X-Trans CMOS sensors, to control moiré and false color without the use of an optical low-pass filter. Its back-illuminated structure enhances image quality while maintaining a high S/N ratio. Furthermore, ISO160, previously available only as extended ISO, is now part of the normal ISO range, allowing you to achieve incredibly clean, noise free images.


About X-Trans CMOS

Moiré is controlled by a low-periodic color filter array
that replicates a highly random arrangement of silver
particles on the analog films and efficient color
interpolation from surrounding pixels.



POINT

Arrangement of all three RGB pixels on every single line

RGB is always placed on any horizontal or vertical line to correctly interpolate colors in high-frequency images



POINT

Arrangement of G pixel on all diagonal lines

G pixels are placed in all diagonal lines. It improves the accuracy of diagonal high-frequency image detection and color interpolation
