Olympus E-M10 III versus Sony A6300
The Olympus OM-D E-M10 Mark III and the Sony Alpha A6300 are two digital cameras that were officially introduced, respectively, in August 2017 and February 2016. Both the E-M10 III and the A6300 are mirrorless interchangeable lens cameras that are based on a Four Thirds (E-M10 III) and an APS-C (A6300) sensor. The Olympus has a resolution of 15.9 megapixel, whereas the Sony provides 24 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.
Body comparison: Olympus E-M10 III vs Sony A6300
The side-by-side display below illustrates the physical size and weight of the Olympus E-M10 III and the Sony A6300. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the E-M10 III – represents the basis or 100 percent across all the size and weight measures).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A6300 is notably smaller (22 percent) than the Olympus E-M10 III. Moreover, the A6300 is slightly lighter (1 percent) than the E-M10 III. It is noteworthy in this context that the A6300 is splash and dust-proof, while the E-M10 III does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can find an overview of optics for the two cameras in the Micro Four Thirds Lens Catalog (E-M10 III) and the Sony E-Mount Lens Catalog (A6300). Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-M10 III was launched at a markedly lower price (by 35 percent) than the A6300, which puts it into a different market segment. 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: Olympus E-M10 III vs Sony A6300
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Olympus E-M10 III features a Four Thirds sensor and the Sony A6300 an APS-C sensor. The sensor area in the A6300 is 63 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the E-M10 III has a native 4:3 aspect ratio, while the one in the A6300 offers a 3:2 aspect.
With 24MP, the A6300 offers a higher resolution than the E-M10 III (15.9MP), but the A6300 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 3.76μm for the E-M10 III) due to its larger sensor. However, the E-M10 III is a somewhat more recent model (by 1 year and 6 months) than the A6300, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the E-M10 III has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
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.

The E-M10 III is a current model that online retailers, such as amazon, will have in stock. In contrast, the A6300 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the A6300 was succeeded by the Sony A6500.
Review summary: Olympus E-M10 III vs Sony A6300
So what conclusions can be drawn? Is the Olympus E-M10 III better than the Sony A6300 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Olympus OM-D E-M10 Mark III:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Sharper images: Has hand-shake reducing image stabilization build-in.
- More affordable: Was introduced into a lower priced category (35 percent cheaper at launch).
- More modern: Is somewhat more recent (announced 1 year and 6 months after the A6300).
Advantages of the Sony Alpha A6300:
- More detail: Has more megapixels (24 vs 15.9MP), which boosts linear resolution by 25%.
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
- Faster burst: Shoots at higher frequency (11 vs 8.6 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (120x67mm vs 122x84mm) and will fit more readily into a bag.
- Longer lasting: Gets more shots (400 versus 330) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- More heavily discounted: Has been on the market for longer (launched in February 2016).
If the count of relative strengths (bullet points above) is taken as a measure, the A6300 emerges as the winner of the match-up (8 : 6 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.
In any case, 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-M10 III and the A6300 in practical situations. 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 expert reviews are important.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
