X-Trans CMOS 4: The First X Series model featuring a back-illuminated sensor The FUJIFILM X-T3 features a back-illuminated 'X-Trans 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.
Its back-illuminated structure enhances images 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. X-Processor 4: The brain that utilizes the full potential of the X-Trans CMOS 4 sensor The FUJIFILM X-T3 uses the X-Processor 4, an evolved version of X Series' image processing engine that boasts advanced processing capabilities.
