The Olympus OM-D E-M5 Mark III is a Micro Four Thirds mirrorless camera with an abundance of speed, precision, and versatility. 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. 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. 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. Full HD 1080p and HD 720p recording are also supported. Audio recording is possible using the built-in stereo microphone, and an external mic jack is available for improved audio recording quality.

The 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. All 121 phase-detection points are cross-type, too, for improved precision in mixed lighting conditions, as well as enhanced subject tracking capabilities. 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. 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.  Additionally, when paired with select lenses featuring optical image stabilization, shake compensation up to 6.5 stops is possible. 

The high-resolution 2.36m-dot electronic viewfinder is available for eye-level monitoring, and it offers a 0.67x maximum magnification for clear, distortion-free viewing. Wide accessory compatibility is provided with the incorporation of a microphone port, a top hot shoe, micro-USB, and micro-HDMI ports, and a 2.5mm port for optional remotes. Built-in Wi-Fi and Bluetooth permit wireless image sharing and remote camera control from a linked smartphone or tablet when using the dedicated O.I.Share app for iOS and Android. TruePic VIII processing aids this shooting function by compensating for any subject movement blur and this feature can also be configured to record 25MP images for file size flexibility.

 This mode works to only record newly detected light sources over time and allows you to watch as an image develops, making it ideally suited for photographing star trails or other moving light sources. As soon as you press the shutter button halfway, frames will begin to be recorded, and once you fully press the shutter, the image will be saved in addition to the previous 35 frames. Additionally, you can hold the shutter button in this mode to keep shooting continuously using the silent electronic shutter function. Anti-flicker shooting automatically detects the frequency/flicker of artificial lighting and activates the shutter at peak brightness moments to render exposures with consistent exposure and color. 

Included with the camera body is the M.Zuiko Digital ED 12-45mm f/4 PRO lens; a 24-90mm-equivalent zoom distinguished by its f/4 constant maximum aperture that strikes a balance between a bright design and a highly compact design to suit its use in everyday situations. A ZERO coating is also featured, which controls flare and ghosting for improved contrast when working in bright and backlit conditions.  Additionally, the lens is weather-sealed to enable its use in trying weather conditions.
