X-Trans CMOS 4

The First X Series model featuring a new back-illuminated sensor
The FUJIFILM X-T3 features a newly-developed back-illuminated “X-Trans*1 CMOS 4” sensor, the fourth generation to feature in the X Series. 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.
