A high-resolution 20.3MP Live MOS sensor works in conjunction with a TruePic VIII image processor to promote fast shooting performance, a sensitivity range from ISO 200-25600, and versatile video recording capabilities. Ideal for photographing moving subjects, too, the sensor and processor combination enables full-resolution continuous shooting up to 8.7 fps. Beyond stills, the E-M10 Mark IV also supports UHD 4K video recording up to 30 fps, Full HD at 60 fps, and high-speed HD recording at 120 fps.

In-body, sensor-shift image stabilization helps to minimize the appearance of camera shake by up to 4.5 stops with any lens in use and compensates for camera movements that become especially noticeable when working with telephoto shots, macro imagery, and long exposures. Furthermore, this advanced image stabilization system works across five axes to compensate for vertical angle rotation, horizontal angle rotation, horizontal shift, vertical shift, and rolling camera shake movement. This range of detected movements serves to benefit traditional still image shooting as well as movie recording and working with moving subjects more effectively.

The quick and intelligent autofocus system uses 121 contrast-detection areas for refined accuracy and focusing speed when working in variety of lighting conditions and shooting situations. Suiting working with moving subjects, continuous autofocus benefits from the same subject-detection algorithm used in the sports-optimized E-M1X and, benefitting portraiture, the same face- and eye-detection functions as the E-M1 Mark III also make it possible to accurately focus on the profile, lowered face, or a partially hidden face. Alternatively, manual focus operation is also benefitted by the inclusion of MF assist functions, including live view magnification and focus peaking.
