X-Trans CMOS 4 Sensor

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. Fujifilm’s X-Trans sensors have alwasy been known to consistently deliver vibrant, true-to-life colors. They also feature a unique design that minimizes moiré effects without the need for a quality-sapping optical low-pass filter. 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. 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. This latest version of X Series’ image-processing engine let’s X-E4 make full use of the technology that drives its professional features. From encoding video to making use of the latest autofocus algorithms, X-E4 has what it takes to perform at level fit for most professionals.
