A camera designed with speed, versatility, and portability in mind, the
Olympus OM-D E-M1 Mark III 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
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.
20.4MP Live MOS Sensor and TruePic IX Image Processor
A high-resolution 20.4MP Live MOS sensor and updated TruePic IX image
processor work in concert to provide notably fast shooting performance,
expanded sensitivity range up to ISO 25600, and versatile 4K video
recording capabilities. Ideal for sports and wildlife shooting, the
sensor and processor combination avail a full-resolution continuous
shooting rate of 15 fps for up to 101 consecutive raw files when working
with the mechanical shutter. When shooting with the silent electronic
shutter, this shooting rate can be boosted up to 60 fps with single-shot
AF for up to 50 consecutive raw frames or 18 fps shooting with
continuous AF for up to 90 consecutive raw frames.
DCI and UHD 4K Video Recording and OM-Log
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 30p 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 both an
external mic jack and headphone jack are available for improved audio
recording and monitoring.
Benefitting recording in varying light conditions, an integrated OM-Log
setting can be used to extend the effective dynamic range and afford a
greater range of control during post-production color grading when used
with the accompanying LUT file. 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.
121-Point All Cross-Type Phase-Detection AF
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.
Additionally, continuous autofocus sensitivity can be set, to benefit
its use while recording video, within five levels for more pleasing
Suiting portraiture, Face Priority and Eye Priority AF are also
available to prioritize the face and eyes of your subject. And for
working in low-light conditions, focusing sensitivity is available down
to -3.5 EV, and a dedicated Starry Sky AF mode can be used for focusing
on stars and other nighttime sky subjects. Converse to the autofocus
capabilities, manual focus users are also benefitted by live view
magnification and focus peaking controls for greater accuracy.
5-Axis Sensor-Shift Image Stabilization
In-body, sensor-shift image stabilization helps to minimize the
appearance of camera shake by up to 7 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 7.5
stops is possible.
Body Design and Connectivity
- High-resolution 2.36m-dot electronic viewfinder is available for
eye-level monitoring, and it offers a high 0.74x maximum magnification
for clear, distortion-free viewing.
- Rear 3.0" 1.037m-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, an LV
Boost mode can be used to optimize the screen's brightness and
prioritize the frame rate when working in dark locations.
- Included BLH-1 rechargeable lithium-ion battery provides approximately
420 shots per charge with normal settings or up to an impressive 900
shots per charge with the quick sleep mode activated.
- The USB Type-C port can be used for quick in-camera battery charging.
- 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.
- Dual SD memory card slots offer improved flexibility for image
storage, allowing you to segregate raw and JPEG files to different
cards, save duplicate files to both cards, or simply double your storage
space with overflow recording. Additionally, one of the card slots is
UHS-II compatible for faster read/write speeds when used with a
compatible UHS-II card.
- Wide accessory compatibility provided with the incorporation of 3.5mm
headphone and microphone ports, a PC sync flash terminal and top hot
shoe, USB Type-C and micro-HDMI ports, and a 2.5mm port for optional
- Rugged splash, dust, and freezeproof construction incorporates
extensive sealing throughout the magnesium alloy body to accommodate
working in harsh weather conditions and trying environments, even when a
cable, microphone, or a set of headphones are attached.
- Supersonic Wave Filter and a dust-resistant coating are used to
greatly reduce the likelihood of dust reaching the sensor.
- Durable shutter unit is rated to perform for over 400,000 actuations.
- Tripod High Res Shot mode offers the equivalent output of an 80MP
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.
The TruePic IX processor aids this process by compensating for any
subject movement blur and this feature can also be configured to record
50MP or 25MP images for file size flexibility.
- Handheld High Res Shot mode, like the Tripod mode, produces a 50MP
JPEG or raw file by compositing sequentially recorded files into a
single image. The Handheld High Res Shot mode differs from the Tripod
mode by recording 16 independent frames, opposed to eight, and the
slight movement caused by hand-holding provides the range of movement
needed to produce the larger final image.
- Simulating the effects of a neutral density filter, Live ND results in
blurred subject movement by compositing exposures to replicate the look
of a single image taken at a slower shutter speed. Particularly suitable
for photographing moving water, five modes are available—ND2, ND4, ND8,
ND16, and ND32—to vary how movement is portrayed.
- 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
- 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 9999 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

lenses, as well as the M.Zuiko Digital MC-14 1.4x and MC-20 2.0x
- 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.
M.Zuiko Digital ED 12-40mm f/2.8 PRO Lens
Included with the camera is the M.Zuiko Digital ED 12-40mm f/2.8 PRO; a
wide-to-portrait-length 24-80mm equivalent zoom. Its sophisticated
optical design, which includes a variety of aspherical, low dispersion,
and high refractive index elements, reduces both chromatic and spherical
aberrations throughout the zoom range for notable clarity, sharpness,
and color accuracy. A ZERO lens coating has also been applied to improve
contrast when working in strong lighting conditions. Beyond the advanced
lens design, this zoom is also characterized by its constant f/2.8
maximum aperture, as well as its durable weather-sealed construction for
working in a variety of conditions. Additionally, a Movie & Still
Compatible autofocus system achieves fast, smooth, and silent focusing
performance, and a manual focus clutch affords instant switching between
