The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Olympus E-M10 III was launched in the US market at a price of $649. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison with a 35mm slide
The size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.
The Olympus E-M10 III features a Four Thirds sensor and has a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the Olympus E-M10 III among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.
For most cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of alternatives.

Many modern cameras cannot only take still pictures, but also record videos. The E-M10 III indeed provides movie recording capabilities. The highest resolution format that the E-M10 III can use is 4K/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the E-M10 III has an electronic viewfinder with a resolution of 2360k dots. The viewfinder offers a field of view of 100% and a magnification of 0.62x. The following tables report on some other key feature differences and similarities of the Olympus E-M10 III and comparable cameras.

The LCD screen on the Olympus OM-D E-M10 Mark III is flexibly attached to the body. In particular, the LCD can be tilted vertically to facilitate odd-angle shots in landscape orientation. This tilting design is often preferred, for example, by street photographers to a fully articulated, swivel type of LCD attachment, as it is more unobtrusive during shooting than a screen that flips out to the side.
One convenient feature of the E-M10 III is the presence of an on-board flash. While this built-in flash is not very powerful, it can at times be useful as a fill-in light to brighten deep shadow areas.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Olympus OM-D E-M10 Mark III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-M10 III offers wifi support. Wifi can be a very convenient means to transfer image data to an off-camera location.
While the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the E-M10 III handle or perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]).

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
Olympus E-M10 III FAQ
Below are some additional questions and answers concerning some particular features of the E-M10 III.
What is the technology behind the imaging sensor in the Olympus E-M10 III?
The camera has a CMOS (Complementary Metal–Oxide–Semiconductor) sensor at its core.
Which image processing chip is used in the Olympus E-M10 III to convert the raw signal into an image file and perform noise reduction and image sharpening?
Olympus equipped the E-M10 III with the TruePic VIII image processor.
What is the ISO sensitivity range of the Olympus E-M10 III?
The camera has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600.
What is the life expectancy of the shutter in the Olympus OM-D E-M10 Mark III?
Olympus does not publish a shutter rating for the E-M10 III. Yet, shutters in comparable cameras from other manufacturers are said to be good for at least 100 000 actuations. It should be noted, though, that this number represents a Mean Time before Failure. The shutter might fail earlier, or it might last longer. Anyway, in order to exhaust an expected shutter life of 100 000 shots over, say, three years, one would have to take about 100 pictures each and every day.
How do I find the shutter count on my Olympus E-M10 III?
Olympus embeds the number of shutter actuations in hidden menus. You can check the number of shots that your E-M10 III has taken up to now by carefully following the steps described on the Olympus E-M10 III shutter count page.
Is completely silent shooting possible with the Olympus E-M10 III?
The camera has an electronic shutter option, so that it is indeed feasible to capture images without any shutter noise.
Do I need to purchase an external camera trigger to shoot time-lapse sequences with the Olympus E-M10 III?
No, the Olympus OM-D E-M10 Mark III has an intervalometer built-in, so that low frequency shooting (for example, flower blooming, sunset, moon rise) can be undertaken without the need to purchase a separate external intervalometer and related software.
Is it difficult to use manual focus lenses with the Olympus E-M10 III?
The E-M10 III offers focus peaking as a manual focus aid. This feature works by placing a colored highlight on in-focus zones within the image.
Does the Olympus E-M10 III feature an autofocus assist light?
Yes, the camera has a lamp built-in that can illuminate the subject and improve autofocus in low-light settings.
What is the fastest shutter speed that can be used with the Olympus E-M10 III for flash photography?
The E-M10 III's flash sync speed is 1/250 sec.
Does the Olympus E-M10 III support the Ultra High Speed (UHS) bus interface for SD cards?
Yes, the camera can indeed use UHS-II cards (data transfer speed of up to 312 MB/s).
Which battery does the Olympus E-M10 III use?
