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 Live 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.
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.
- 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.
- Rear 3.0" 1.04m-dot LCD monitor features a vari-angle design to support working from a variety of angles, and it is also a touchscreen for intuitive menu navigation and image playback. Additionally, a Live View Boost mode can be used to optimize the screen's brightness and prioritize the frame rate when working in dark locations.
- Included BLS-50 rechargeable lithium-ion battery is used to provide approximately 310 shots per charge .
- In-camera battery charging is supported via the micro-USB port.
- Single SD memory card slot is UHS-II compatible for fast read/write speeds.
- Wide accessory compatibility 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.
- Rugged splash, dust, and freezeproof construction incorporates extensive sealing throughout the body design to accommodate working in harsh weather conditions and trying environments.
- Supersonic Wave Filter and a dust-resistant coating are used to greatly reduce the likelihood of dust reaching the sensor.
- Built-in Wi-Fi and Bluetooth permits 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.
- High Res Shot mode offers the equivalent output of a 50MP JPEG image or 80MP raw image by combining eight sequentially recorded frames into a single, larger image. In between each of the exposures, the sensor-shift stabilization mechanism moves slightly in order to acquire more information than in a single exposure and these frames are then composited into a final image with greater resolution and color detail. 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.
- Live Composite is a unique long exposure mode that allows you to gradually build up an exposure over time without overexposing key elements within the frame. 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.
- Live Bulb and Live Time settings can be used to produce creative long exposure imagery. Live Bulb lets you hold the shutter open for up to one minute and Live Time lets you press the shutter button once to open the shutter and then press again within a minute to end the exposure.
- Pro Capture Mode is a unique setting that starts recording and buffering full-resolution JPEG or raw images prior to fully depressing the shutter. 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.
- Interval shooting is supported for up to 999 frames with 1-second to 24-hour exposure intervals.
- 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.
- In-Camera Focus Stacking will automatically record eight images of a subject while shifting the plane of focus slightly, then composite these exposures into a single frame to exhibit an extended depth of field. Alternatively, Focus Bracketing allows you to record between 3-999 frames with adjustable focus steps in a 1-10 range for manual compositing during post-production. These modes are only available when working with M.Zuiko Digital ED 60mm f/2.8 Macro, 12-40mm f/2.8 PRO, 40-150mm f/2.8 PRO, 30mm f/3.5 Macro, 7-14mm f/2.8 PRO, 8mm f/1.8 Fisheye PRO, 300mm f/4 IS PRO, and 12-100mm f/4 IS PRO lenses.
- Keystone Compensation allows you to correct for convergence when working in live view. Similarly, Fisheye Compensation allows you to use the M.Zuiko Digital ED 8mm f/1.8 Fisheye PRO lens as a rectilinear wide-angle lens by correcting and eliminating distortion.
