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, the sensor is equipped with 2.16M phase detection AF pixels covering approx. 100% of the frame which supports high autofocus performance regardless of where the subject is located within the frame. X-Processor 4, the latest version of X Series’ image processing engine, combined with the latest 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 maximizes the full potential of X-Trans CMOS 4 sensor to deliver the highest performance in all aspects in the history of X Series. With its X-Trans CMOS 4 sensor and X Processor 4 image processing engine combining to produce best-in-class autofocus performance, the X-E4 offers AF speed equivalent to that of other high-performance X Series Mirrorless Cameras (X-T4, X-Pro3), reaching an incredible 0.02 secs. No matter the situation, X-E4’s AF can track and hold the most difficult of moving subjects with tenacious speed, or lock onto an individual’s face with wonderfully intelligent anticipation. Metal hand grip improves the grip on the camera and reduces the chances of camera shake, especially when using heavy, large aperture lenses. This grip can be left in place when using a tripod and enables users to change the battery and SD card without having to remove the grip from the body. The Arca Swiss plate can be used as a quick release with compatible tripods. Metal thumb rest can be fitted to the camera’s hot shoe to provide extra comfort when holding the camera. The surface of the thumb rest is covered in rubber for added stability and its unique shape allows for easy access to the camera’s controls and dials.
