A camera designed with speed, versatility, and portability in mind, the Olympus OM-D E-M1 Mark III / Mark 3 Mirrorless Digital Camera (Body Only , Black) is a well-rounded Micro Four Thirds mirrorless camera suitable for a variety of stills and video needs. Featuring a 20.4MP Live MOS sensor and an updated TruePic IX image processor, the camera is characterized by its quick continuous shooting, up to 60 fps with an electronic shutter and 15 fps with a mechanical shutter, as well as DCI and UHD 4K video recording. The sensor and processor also offer a sensitivity range up to ISO 25600 while a sophisticated 5-axis sensor-shift image stabilization system compensates for up to 7.5 stops of camera shake for sharper handheld shooting. Beyond imaging, the sensor's design also incorporates 121 on-chip phase-detection points, all of which are cross-type, along with 121 contrast-detection areas for fast and precise focusing and subject tracking performance.

In regard to the E-M1 III's physical design, it features a durable magnesium alloy body along with extensive weather-sealing to support working in harsh climates. Both a 2.36m-dot, 0.74x-magnification electronic viewfinder and 3.0" 1.037m-dot vari-angle LCD touchscreen are featured, too, for intuitive control and working from a variety of angles. Additionally, built-in Wi-Fi and Bluetooth further expand sharing and remote shooting capabilities, and dual SD card slots afford greater file saving flexibility.
