Revolving around a highly versatile sensor, the X-E4 features an APS-C-format 26.1MP X-Trans CMOS 4 sensor, which has a back-illuminated design to afford smooth tonal rendering, improved low-light performance, and a wide native sensitivity range of ISO 160-12800. As an X-Trans sensor, it utilizes a randomized pixel array, too, which provides a high degree of image quality and sharpness due to the omission of an optical low-pass filter. Versus conventional pixel patterns, the X-Trans design more closely mimics the organic nature of film in order to produce nuanced colors and tonal transitions, while also reducing moiré and aliasing.

The sensor’s design also includes an expanded phase-detection autofocus system, which has 425 selectable points that cover nearly the entire sensor area. This AF system delivers faster, more accurate focusing performance in a variety of lighting conditions down to -7 EV. Complementing the imaging and focusing capabilities, an updated X-Processor 4 is also featured, which has a quad-core CPU, and delivers faster, more responsive performance throughout the camera system, including a full-resolution 8 fps shooting rate with the mechanical shutter, 20 fps rate with an electronic shutter, or a 30 fps rate with an electronic shutter and a 1.25x crop.

Expanding its capabilities beyond stills, the X-E4 offers a versatile array of video capabilities, including internal DCI/UHD 4K recording at up to 30 fps and Full HD recording up to 240 fps for ultra slow-motion playback. Greatly benefitting overall video performance, the speed of the X-Processor 4 enables fast read speeds when recording video and helps to reduce rolling shutter distortion when filming moving subjects. Also, a micro-HDMI port enables 10-bit 4:2:2 recording to an optional external recorder.

Also, the camera features a 3.5mm microphone jack and 2.5mm remote port with included headphone adapter for more advanced audio solutions.

• Bright, high-resolution 2.36m-dot OLED electronic viewfinder has a 0.62x magnification for clear and comfortable eye-level viewing.
• Tilting 3.0″ 1.62m-dot LCD has a touchscreen design for intuitive operation and playback, and the 180° upward tilting design greatly benefits working from high and front-facing shooting angles.
• The top plate incorporates a series of physical controls for fast, intuitive tuning exposure settings, including dedicated shutter speed and exposure compensation dials that offer direct adjustment, even when the camera is off. This exposure compensation dial also has a C position to afford an expanded +/- 5 EV range when working with the command dials.
• Rear joystick is available for intuitive selecting and switching of AF points as well as menu navigation and image playback.
• Integrated Bluetooth and Wi-Fi connectivity allows for wirelessly sharing images to a mobile device or to use the device to remotely control the camera.
• Single SD memory card slot supports the UHS-I standard.
• Included NP-W126S battery provides approximately 380 frames per charge when working with the EVF.

• Provia: The standard contrast and normal saturation color transparency film
• Velvia: High contrast, high color saturation, and vivid color transparency film
• Astia: Subdued contrast and color saturation with a look that is ideal for portraits
• Classic Chrome: Delivers muted tones and deep color reproduction, similar to a dated slide film
• Classic Neg: Muted contrast but vibrant colors with a vintage filmic feel
• PRO Neg: Available with both Hi and Std. contrast options, this mimics the punchy-but-natural feeling of their professional-grade color negative film
• Eterna: For a cinematic look, this provides a flat color, low saturation look well-suited to post-production color grading
• Eterna Bleach Bypass: Refines the standard Eterna look with a higher key, higher contrast feeling while maintaining the overall desaturated look
• Acros: Based on the popular B&W film, this monochrome mode has a distinct tonality and graininess and can be used along with Yellow, Red, and Green contrast filter effects
• B&W: Straightforward and classic black and white effect with Yellow, Red, and Green contrast filter options
• Sepia: Everyone’s favorite old-timey look mimicking the popular alternative process
• In addition to simulating specific film types, a Grain Effect mode is also available to replicate the look of old film photos with an organic textured appearance, which is especially noticeable when printing. Color Chrome and Color Chrome Blue effects are also available to deepen color, tonal response, and gradation with higher saturation colors.

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.
