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. Included with the camera body is the super slim pancake prime XF 27mm f/2.8 R WR lens. This 41mm-equivalent lens features an updated weather-sealed design along with a manual aperture ring for intuitive exposure control adjustment. In terms of optics, one aspherical element is featured and helps to reduce distortion and spherical aberrations, and a Super EBC coating has also been applied to control flare and ghosting. Additionally, benefitting both photo and video applications, a high-torque DC coreless motor is used to realize quick, accurate, and near-silent autofocus performance.
