Packing a wealth of capabilities within an especially compact design, the Olympus OM-D E-M5 Mark III is a Micro Four Thirds mirrorless camera with an abundance of speed, precision, and versatility. Featuring a 20.4MP MOS sensor and a TruePic VIII image processor, the E-M5 Mark III offers quick continuous shooting up to 10 fps with a mechanical shutter, up to 30 fps shooting with an electronic shutter, and DCI and UHD 4K video recording. The sensor and processor combination also affords a sensitivity range up to ISO 25600 while a sophisticated 5-axis sensor-shift image stabilization system compensates for up to 6.5 stops of camera shake for sharper handheld shooting. Complementing the imaging specs, the sensor's design also incorporates 121 phase-detection points, all of which are cross-type, along with 121 contrast-detection areas for fast and precise focusing and subject tracking performance.
Despite all of its performance-oriented attributes, the E-M5 Mark III manages to retain a sleek design, which is also weather-sealed for use in trying weather conditions. A high-resolution 2.36m-dot 0.67x-magnification OLED viewfinder is featured along with a 3.0" 1.04m-dot touchscreen LCD, which sports a vari-angle design to suit working from high, low, and front-facing angles. Additionally, built-in Wi-Fi and Bluetooth enable wireless transferring and remote camera control from linked mobile devices.
A high-resolution 20.4MP 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 4K video recording capabilities. Ideal for photographing moving subjects, the sensor and processor combination also avails a full-resolution continuous shooting rate of 10 fps for up to 150 consecutive raw files when working with the mechanical shutter. When shooting with the silent electronic shutter, this shooting rate can be boosted up to 30 fps with single-shot AF for up to 23 consecutive raw frames or 10 fps shooting with continuous AF for up to 152 consecutive raw frames. If recording JPEGs, unlimited sequential shooting is possible until the memory card is full.
The sensor and processor also support recording both DCI (4096 x 2160) and UHD (3840 x 2160) 4K movies. When working in DCI, a true 24.00 fps frame rate is used, along with IPB compression and a 237 Mb/s bit-rate, and UHD 4K is available in frame rates up to 29.97p and a 102 Mb/s bit-rate. Full HD 1080p and HD 720p recording is also supported. Audio recording is possible using the built-in stereo microphone, and an external mic jack is available for improved audio recording quality. Use of an external recording monitor is also possible, via HDMI output, which supports 4:2:2 8-bit color for a greater color correction range.
Additionally, a Time-lapse Movie mode is also available for recording up to 4K UHD resolution with a 5 fps shooting rate to highlight subject changes or movement over a longer period of time. Full HD and HD time-lapse settings are available, too, as well as a high-speed Full HD setting with 120 fps frame rate.
An advanced autofocus system combines both 121 on-chip phase-detection points and 121 contrast detection areas for focusing performance that is both quick and accurate. All 121 phase-detection points are cross-type, too, for improved precision in mixed lighting conditions, as well as enhanced subject tracking capabilities. Different focusing modes are available to suit working in various shooting conditions, including 121-point, for general use; Group 25-point, for moving subjects, such as birds and wildlife, and when 121-point is too wide; Group 9-Point, for smaller and more distant subjects; Group 5-Point, for when 9-point is too wide or to suit working with nearer moving subjects; Single, for working with still or small subjects that are not moving; and Small AF, for working with close-up subjects. Custom AF targets can also be set, for working with specific numbers of focus points within the 121-point grid, and an AF limiter function allows you to constrain the focusing distance within a specified range for more responsive performance.
In-body, sensor-shift image stabilization helps to minimize the appearance of camera shake by up to 5.5 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 unique 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. Additionally, when paired with select lenses featuring optical image stabilization, shake compensation up to 6.5 stops is possible.
