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.
X-Processor 4

The brain that utilises 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. The new processor, combined with a new algorithm, enhances the Film Simulation modes, substantially improving the camera’s ability to track moving subjects, boosts AF’s speed and accuracy, and allows for a more diverse range of video functions. It maximises the full potential of X-Trans CMOS 4 sensor to deliver the highest performance in all aspects in the history of X Series.
