The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Olympus E-M5 III was launched in the US market at a price of $1,199. 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.
The Olympus E-M5 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-M5 III among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 comparators.

Many modern cameras cannot only take still pictures, but also record videos. The E-M5 III indeed provides movie recording capabilities. The highest resolution format that the E-M5 III can use is 4K/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-M5 III has an electronic viewfinder with a resolution of 2360k dots. The viewfinder offers a field of view of 100% and a magnification of 0.68x. The following tables report on some other key feature differences and similarities of the Olympus E-M5 III and comparable cameras.

One feature that differentiates the E-M5 III from many other cameras is in-body image stabilization (IBIS). The E-M5 III reduces the risk of handshake-induced blur with all attached lenses, while cameras without IBIS have to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.
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-M5 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-M5 III has a microphone port. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
While the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the E-M5 III in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods 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-M5 III FAQ
Below are some additional questions and answers concerning some particular features of the E-M5 III.
What type of imaging sensor is used in the E-M5 III?
The camera is build around a CMOS (Complementary Metal–Oxide–Semiconductor) sensor.
Which image processing chip is used to convert the raw signal into an image file and perform noise reduction and image sharpening?
Olympus equipped the E-M5 III with the TruePic VIII image processor.
What is the ISO sensitivity range of the E-M5 III?
The camera has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 64-25600.
Does the camera have a selfie-friendly screen?
Yes, the LCD-screen of the E-M5 III is flexible and can be turned to be front-facing for capturing selfies.
What is the life expectancy of the shutter in the Olympus OM-D E-M5 Mark III?
Olympus does not publish a shutter rating for the E-M5 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.
Is completely silent shooting possible with the Olympus E-M5 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?
No, the Olympus OM-D E-M5 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-M5 III?
The E-M5 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-M5 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 flash?
The E-M5 III's flash sync speed is 1/250 sec.
Does the Olympus E-M5 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 E-M5 III use?
The camera gets its power from the BLS-50 (here at amazon), which is a rechargeable Lithium-Ion power pack.
Where can I find the best deals for the E-M5 III?
