4/3 (MFT)

The Olympus OM-D E-M1 Mark III is a Micro Four Thirds camera. What it lacks in sensor size and megapixels, it more than makes up for in portability, comfort, and features. Though it isn't as compact as siblings like the Olympus OM-D E-M5 Mark III, the E-M1 Mark III features a sturdy, weather-sealed design that's advertised to be splashproof, dustproof, and freezeproof down to 14F/-10C. Throw in a high-resolution 80MP photo mode, continuous shooting up to 60 fps (15 fps with mechanical shutter), and in-body image stabilization (IBIS) rated for up to 7.5 EV, and you've got a well-rounded camera without the bulk of larger-sensor systems.

Our Verdict

7.7 Travel Photography

The Olympus E-M1 Mark III is good for travel photography. It's relatively portable and uses Micro Four Thirds lenses, which tend to be more compact. It's incredibly comfortable to shoot with and features remarkably sturdy construction, with weather-sealing and temperature resistance. It also has a highly effective in-body image stabilization feature, making it easier to take handheld shots at slower shutter speeds. Photos look detailed with pleasing colors and good noise handling, though its smaller sensor makes it a bit less suited to low-light photography compared to some APS-C and full-frame alternatives. It has a good overall battery life, too, but you can't use it while it charges, which is a bit inconvenient if you run out of battery on the go. Its autofocus system also isn't the most effective or reliable with busier scenes or subjects.

Pros
  • Great overall image quality.
  • Relatively lightweight and portable.
  • Sturdy dustproof, splashproof, freezeproof design.
  • Good battery life.
Cons
  • Autofocus lags behind the best.
  • Good low light performance for MFT, but lacking compared to full frame.
7.9 Landscape Photography

The Olympus E-M1 is great for landscape photography. It's a remarkably well-built camera with weather-sealing and a relatively portable design, making it a good option for long hikes or shoots at remote shooting locations. JPEG images look good straight out of the camera, with minimal noise and pleasing colors. If you prefer to process your own photos, its RAW noise handling and dynamic range are good for a Micro Four Thirds camera but fall short compared to larger-sensor options. On the upside, the camera has a 'High Res Shot' feature that combines multiple shots to create a single image with a resolution of up to 80 megapixels, giving you greater dynamic range and more leeway to crop and edit your files or get high-quality prints.

Pros
  • Great overall image quality.
  • Relatively lightweight and portable.
  • Sturdy dustproof, splashproof, freezeproof design.
  • 'High Res Shot' mode.
Cons
  • Good low light performance for MFT, but lacking compared to full frame.
  • Dynamic range is limited compared to larger-sensor cameras.
8.1 Sport & Wildlife Photography

The Olympus OM-D E-M1 Mark III is great for sports and wildlife. With its mechanical shutter, it can shoot at a very fast 15 fps to help you capture moments of fast action or moving subjects like birds. In addition, it has a 'Pro Capture' drive mode that lets you start burst shooting with a half-press of the shutter, and it only records a set of images once you fully press down, ensuring you don't miss a critical moment. Overall, image quality is great, though because of the camera's limited max ISO, you'll need to use faster lenses to get fast-enough shutter speeds for moving subjects in more demanding lighting conditions, like indoor arenas or stadiums. Its autofocus system also lags behind leading competitors in this area. On the upside, MFT lenses tend to have more focal reach without the bulk of larger-sensor equivalents.

Pros
  • Blazing fast continuous shooting speed.
  • Great overall image quality.
  • Relatively lightweight and portable.
  • Sturdy dustproof, splashproof, freezeproof design.
  • 'Pro Capture' mode.
Cons
  • Autofocus lags behind the best.
  • Good low light performance for MFT, but lacking compared to full frame.
7.6 Vlogging

The Olympus E-M1 III is a good choice for vlogging. It features an excellent in-body image stabilization feature to smooth out camera shake in handheld video. Its fully articulated screen lets you monitor yourself while recording, and it's weather-sealed, meaning you can shoot in more adverse weather conditions without worry. It's also relatively lightweight and portable, although it's a tad cumbersome for vlogging purposes compared to more compact options. Video quality is good overall, but it doesn't perform as well in dim lighting. It can also record at a fairly wide range of frame rates, particularly in 1080p, which includes a high-speed capture mode that records 120 fps video.

Pros
  • Relatively lightweight and portable.
  • Fully articulated screen.
  • Sturdy dustproof, splashproof, freezeproof design.
Cons
  • A little bulky for vlogging.
  • Not as well-suited for low-light.
7.8 Studio Video

The Olympus E-M1 Mark III is good for recording studio videos. It delivers good overall video quality in more controlled lighting conditions. It has a fully articulated screen, a full set of inputs and outputs, as well as two UHS-II SD card slots, both of which are easily accessible when the camera is mounted on a tripod. While the camera includes flat and Log profiles, it's limited to 8-bit recording internally, giving you less to work with when grading and editing your footage. Thankfully, it can output 12-bit 4:2:2 video via HDMI, so you can capture video with more color information if you connect an external recorder.

Pros
  • Relatively lightweight and portable.
  • Fully articulated screen.
  • Sturdy dustproof, splashproof, freezeproof design.
  • Can output 12-bit 4:2:2 video over HDMI.
Cons
  • Autofocus lags behind the best.
  • Limited to 8-bit 4:2:0 internally.
  • Not as well-suited for low-light.
5.1 Action Video

The Olympus E-M1 isn't meant for action videos. It isn't designed for mounting on a helmet or other action cam rig, and it's limited to 30 fps recording in 4k. Though it has a 'High Speed' mode in 1080p, which records video at 120 fps for slow-motion playback, this mode incurs a noticeable crop. Also, while the camera is very sturdy and features a splashproof and freezeproof design, it isn't fully waterproof, making it unsuitable for underwater or water sports video. The camera does have a very effective stabilization system, but it can't eliminate camera jitter completely or as effectively as an action camera, especially when moving at a quicker pace.

Pros
  • Relatively lightweight and portable.
  • Sturdy dustproof, splashproof, freezeproof design.
Cons
  • Not waterproof.
  • Not meant for action cam rigs.
  • No high-speed frame rates in 4k.
  • Not as well-suited for low-light.

Differences Between Sizes And Variants

The Olympus E-M1 Mark III comes in one color variant: 'Black'. You can buy the camera body on its own or bundled with the Olympus M.Zuiko ED 12-40mm f2.8 PRO lens. You can see our unit's label here.

Let us know if you come across another variant, and we'll update the review.

Compared To Other Cameras

The Olympus E-M1 III is a well-rounded Micro Four Thirds camera. It's more comfortable to shoot with than most cameras, with a design aimed at enthusiast shooters looking for a more portable solution for photo and video work. The smaller size of its sensor gives it a highly effective in-body image stabilization feature without too much extra bulk. However, it isn't the best option for low-light environments.

The camera borrows a lot of extra features that Olympus first introduced on its flagship Olympus OM-D E-M1X, including 'High Res Shot' mode and Live ND filters, made possible by its TruePic IX processor. All in all, it's a good middle ground for those who want some of the high-end features of Olympus' flagship model but at a lower price point and in a more compact size.

For more options, check out our recommendations for the best vlogging cameras, the best cameras for wildlife photography, and the best digital cameras.

Olympus OM-D E-M5 Mark III

The Olympus OM-D E-M1 Mark III is more well-rounded than the Olympus OM-D E-M5 Mark III. It has a faster max continuous shooting speed, offers better battery life, and feels more comfortable to shoot with thanks to its larger handgrip and slightly larger EVF. It also has an extra SD card slot, a headphone jack, and records video at higher bit rates. On top of that, the E-M1 III has some extra features that the E-M5 III lacks, like a digital ND filter. That said, if portability is your priority for something like travel or vlogging, the E-M5 Mark III is more compact and offers roughly equivalent image quality, since both cameras use the same sensor with similar processors.

Panasonic LUMIX GH5 II

The Panasonic LUMIX GH5 II and the Olympus OM-D E-M1 Mark III are both great Micro Four Thirds cameras, but they're suited to different uses. The Panasonic offers more advanced video features, including more 4k frame rate options, more file format and codec options, and better internal recording capability. If you're more of a photographer or hybrid shooter, the Olympus is more well-rounded, with a high-resolution photo mode, faster burst shooting, and a slightly more reliable autofocus system.

Olympus OM-D E-M10 Mark IV

The Olympus OM-D E-M1 Mark III sits above the Olympus OM-D E-M10 Mark IV in Olympus's camera lineup. The E-M1 III is an enthusiast-grade camera with a weather-sealed construction that feels sturdier and more comfortable to shoot with than the entry-level E-M10 Mark IV. Though they use similar sensors, the E-M1 III has a more advanced processor that gives it better RAW noise handling at higher ISOs. It also has a more advanced hybrid autofocus system that gives it significantly better AF performance. However, it's a lot bulkier and pricier than the E-M10 IV. 

Fujifilm X-T4

The Fujifilm X-T4 and the Olympus OM-D E-M1 Mark III are both great all-around cameras, but the Fujifilm has a slight edge thanks to its larger sensor, slightly more compact design, and more advanced video features. Though the Fujifilm isn't quite as comfortable to shoot with, its APS-C sensor has better noise handling and dynamic range than the smaller Micro Four Thirds sensor of the Olympus. It also has a better battery life and higher-resolution EVF. That said, the Olympus has a faster max burst rate and extra features like a high-resolution photo mode and digital ND filters that still make it an appealing option for photography. However, when it comes to video, the Fujifilm offers better internal recording, higher bit rates, and 4k / 60 fps recording. 

Sony α6000

Although it has a smaller Micro Four Thirds sensor, the Olympus OM-D E-M1 Mark III is better than the Sony α6000, which has an APS-C sensor. The Sony is more portable, but it lacks a lot of the advanced features that the Olympus has, like in-body image stabilization, a high-resolution composite photo mode, and 4k video recording. If you're looking for a versatile camera with plenty of features for a range of photo and video work, the Olympus is a great option. If you're on a budget and want something simpler and more portable, the Sony is still a great option for casual photography.

The Olympus E-M1 feels incredibly comfortable to shoot with. It has a very ergonomic handgrip that feels nice in the hand. There are plenty of buttons and dials, and they're mostly well-placed, so you can easily adjust settings even with your eye to the viewfinder. The power switch is a little oddly placed on the left side of the body, meaning you have to use two hands to power the camera on and off. The SD card slots are easily accessible on the side of the camera, so you can switch out memory cards while the camera is mounted on a tripod. The eyecup isn't the most comfortable, and the joystick on the back is a little hard to use.

The Olympus E-M1 III has good battery life. It's rated for 420 shots according to CIPA standards, though that number should be taken with a grain of salt, and you can typically expect to get more shots than specified. It's a higher rating than many mirrorless cameras, including other Olympus cameras like the Olympus OM-D E-M5 Mark III, but it still falls short compared to most DSLRs. You should still be able to get a lot of shots out of it over a day or even across multiple days, depending on how you use the camera. The E-M1 III also has a power-saving setting called 'Quick Sleep Mode', which is advertised to give you approximately 900 shots on a full charge.

When using HDR mode, which combines multiple exposures into one image with an expanded dynamic range, you can choose from two different settings: 'HDR1' produces a more natural-looking photo, while 'HDR2' gives a more exaggerated "painterly" effect, according to Olympus.

The Olympus E-M1 also has a 'High Res Shot' mode to capture images with a higher resolution than the sensor, which is great for making high-quality prints or giving you more flexibility to crop your photos. It's a complex process, but it essentially works by taking advantage of the camera's IBIS to shift the sensor around in small increments for each shot and then combining them to effectively create an image with a much higher resolution. You can set the shooting method to either 'Handheld' or 'Tripod', and choose between 80MP, 50MP, or 25MP RAW or JPEG files, although 80MP is only available in tripod mode. See here for a sample High Res Shot taken using the 'Handheld' method and here for a 'Tripod' version.

The Olympus OM-D E-M1 Mark III has a wide range of drive modes for burst shooting. Its high-speed continuous drive mode can shoot from 10 fps up to 15 fps, allowing you to capture quick sequential shots of fast-moving subjects, while its low-speed drive mode can shoot at up to 10 fps if you don't need as quick a shooting speed. Both high and low sequential shooting are available in silent mode, which uses the electronic shutter at higher speeds to capture burst photos without noise. It's great for skittish wildlife or situations in which you need to be discreet. In silent mode, the camera can shoot at up to 60 fps in high-speed mode or up to 18 fps in low-speed mode.

The camera also has a 'Pro Capture' mode, available in both high and low speed, that lets you begin continuous shooting by half-pressing the shutter and finish a burst by pressing all the way. If you half-press the shutter and let go, the camera won't save any photos, but if you press all the way, it'll save a certain number of frames from before the full press and a number of frames after the press. It's a great feature for pros who need to be at the ready lest they miss a critical moment. The camera lets you set the burst rate at up to 60 fps in high-speed Pro Cap mode or up to 18 fps in low speed, as well as letting you choose how many pre-shutter frames it records.

All of these modes give you a wide range of speeds to choose from and include an option to limit the frame count to 25 frames for those who want to ensure they don't fill up their card with an unnecessarily large number of shots. Note also that at ISO settings above 8000, the max burst rate in silent and Pro Cap modes drops to 30 fps.

The Olympus E-M1 Mark III has a hybrid AF system that uses both phase-detection and contrast-detection AF points.

The camera includes face and eye detection and does a good overall job tracking moving human subjects. It's certainly a step up from both the Olympus OM-D E-M5 Mark III and the Olympus OM-D E-M10 Mark IV, with a higher rate of in-focus shots.

General subject or object tracking is okay but falls short when compared to more advanced AF systems from Sony or Canon and even other MFT cameras like the Panasonic LUMIX GH5 II. Generally, it does a fair job of keeping up with its target, but you may still notice some hunting or dropping out of focus.

Thankfully, the camera has a lot of settings to fine-tune the AF performance, including a sensitivity adjustment that can help it more easily track faster-moving subjects, as well as center priority settings that will prioritize focus points in the center of the AF area.

The camera also has a specialized 'Starry Sky AF' mode that's optimized for astrophotography and lets you choose between 'Speed' and 'Accuracy' priority. When 'Starry Sky AF' is enabled, you simply half-press the shutter, and the camera scans the scene and adjusts the lens elements to ensure that the stars in the scene are in focus. Though this process can take several seconds, it's possible to get an in-focus handheld shot of the night sky thanks to the camera's excellent IBIS, and it's a nice feature for astrophotographers who don't want to deal with the hassle of manual focus.

The Olympus OM-D E-M1 Mark III has a fantastic in-body image stabilization (IBIS) feature that's rated for up to 7 EV of stabilization, meaning you can slow down your shutter speed up to 7 stops and still get a clear image. When paired with an optically stabilized Olympus lens, that jumps up to 7.5 stops. The camera uses five-axis sensor-shift stabilization to achieve this, allowing you to take handheld photos at very slow shutter speeds.

The Olympus E-M1 Mark III has good dynamic range, especially relative to other Micro Four Thirds cameras. It does a pretty good job of preserving highlight and shadow detail in high-contrast scenes like our skate park sample gallery image, which you can download here. Photos have a fair amount of exposure latitude, if you want to recover shadow detail, for example, but pushing the exposure too far results in very noticeable noise, especially compared to cameras with larger sensors, like the full-frame Sony a7 III (see here).

The camera does have a useful 'Highlight and Shadow Control' feature that lets you adjust the brightness of shadows or highlights independent of each other. On top of that, it has a 'Highlight & Shadow' Live View display setting that shows you if any shadows or highlights in the frame are clipping.

The Olympus E-M1 III has good internal recording capability. It can reach a max bit rate of about 162 Mbps when recording in DCI 4k, which is good for those who want higher-quality video capture, although it falls significantly short of the advertised 237 Mbps. Standard UHD 4k maxes out at 80 Mbps. Unfortunately, the camera is limited to 8-bit recording internally, giving you less flexibility when editing compared to cameras that can record 10-bit video. Thankfully, we never experienced any overheating while testing its battery life, but recording time is capped at 29 minutes. Overall, it offers good recording capability but is still limited compared to competitors like the Panasonic LUMIX GH5 II or even the Fujifilm X-T4, both of which have more advanced video capabilities.

The Olympus E-M1 Mark III has a good autofocus system for 4k video. It supports face tracking, but unlike the Olympus OM-D E-M5 Mark III, it doesn't support eye-tracking in video mode. Still, it does a good job tracking moving faces. It's fairly quick and accurate; however, it can sometimes lose its target with more erratic or faster-moving subjects. It's pretty good at calculating the distance of an object or subject moving head-on, though it can sometimes step or be slow to fully focus on the target after it's stopped moving. Generally, the AF is well-suited to a range of shooting situations, but it isn't as quick or accurate as competitors like Sony or Canon.

4k video quality is good overall. The camera captures excellent-quality 4k footage under more controlled lighting conditions. It isn't as well-suited to low light since the ISO maxes out at 3200 in video mode. Because of this, low-light footage looks very dark when using the settings dictated by our standardized methodology, although the image still looks fairly sharp. With the aperture set to max, however, 4k video looks a lot cleaner and more detailed, which you can see for yourself here. On top of that, the auto white balance can be a bit finnicky, causing shifts in color temperature as a subject moves closer to the lens, which you can see in our face-tracking AF video.

If you want slightly sharper, more detailed footage, you can also shoot in 'C4k' or Cinema 4k (4096 x 2160 resolution). See here for a test scene extract.

Rolling shutter isn't too bad on the Olympus E-M1 Mark III. If you're shooting handheld, you're unlikely to notice a lot of distortion unless you're panning the camera very quickly.

The Olympus E-M1 Mark III can record 1080p video at up to 60 fps in regular movie mode, which is great for shooting smooth action footage or generating slow-motion video. It also has a 'High Speed' movie mode that captures 1080p video at 120 fps, though it incurs a 1.3x crop. You can set the playback speed to 60 fps, 50 fps, 30 fps, 25 fps, or 24 fps to get varying levels of slow motion.

The Olympus E-M1 Mark III has good internal recording capability in FHD. As with 4k, it's limited to 8-bit 4:2:0 recording internally, but it records at fairly high bit rates, allowing it to capture higher-quality video relative to its resolution. Recording time limit is pretty standard at just under half an hour, which lets you record fairly long takes but is still limiting for videographers who might want to record for longer.

Autofocus performs roughly the same in FHD as it does in 4k. It does a good job of detecting subjects and keeping them in focus, though it can sometimes be slow to find its target after they've moved, especially when compared to some competing AF systems. All in all, it's a solid AF system that can keep up in most situations but can have a bit of trouble with more demanding subjects.

The Olympus E-M1 Mark III has good FHD video quality. Videos look reasonably sharp and detailed, but low light performance is just okay compared to cameras with larger sensors. Unlike the Olympus OM-D E-M5 Mark III, this camera is also limited to ISO 3200 in video mode, making it less adaptable to darker lighting conditions, especially within the constraints of our standardized testing methodology, which results in very dark video. When shot with aperture set to its max (f/2.8 with the lens we tested), video footage looks a lot better and more detailed, although there's still some noticeable noise and loss of detail compared to videos shot in more controlled lighting.

Rolling shutter on the Olympus E-M1 Mark III isn't too bad when shooting in FHD. It's mostly noticeable at faster speeds, but it isn't especially distracting or distorted with simpler and slower camera movements.
