Olympus E-M10 III versus Fujifilm X-T20
The Olympus OM-D E-M10 Mark III and the Fujifilm X-T20 are two digital cameras that were officially introduced, respectively, in August 2017 and January 2017. Both the E-M10 III and the X-T20 are mirrorless interchangeable lens cameras that are based on a Four Thirds (E-M10 III) and an APS-C sensor. The Olympus has a resolution of 15.9 megapixel, whereas the Fujifilm provides 24 MP.
The physical size and weight of the Olympus E-M10 III and the Fujifilm X-T20 are illustrated in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All size 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 Fujifilm X-T20 is somewhat smaller (4 percent) than the Olympus E-M10 III. Moreover, the X-T20 is slightly lighter (7 percent) than the E-M10 III. In this context, it is worth noting that neither the E-M10 III nor the X-T20 are weather-sealed.
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 Fujinon X Lens Catalog (X-T20). 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 comparisons there.

The listed 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 28 percent) than the X-T20, 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.
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. 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.
Of the two cameras under consideration, the Olympus E-M10 III features a Four Thirds sensor and the Fujifilm X-T20 an APS-C sensor. The sensor area in the X-T20 is 64 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 X-T20 offers a 3:2 aspect.
With 24MP, the X-T20 offers a higher resolution than the E-M10 III (15.9MP), but the X-T20 nevertheless has larger individual pixels (pixel pitch of 3.92μm 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 7 months) than the X-T20, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.
For most cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (4K/30p).
Apart from body and sensor, cameras can and do differ across a variety of features. The E-M10 III and the X-T20 are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 2360k dots. The table below summarizes some of the other core capabilities of the Olympus E-M10 III and Fujifilm X-T20 in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the E-M10 III and the X-T20 are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The X-T20 replaced the earlier Fujifilm X-T10, while the E-M10 III followed on from the Olympus E-M10 II.
So how do things add up? Is the Olympus E-M10 III better than the Fujifilm X-T20 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Olympus OM-D E-M10 Mark III:
- Sharper images: Has hand-shake reducing image stabilization build-in.
- More affordable: Was introduced into a lower priced category (28 percent cheaper at launch).
- More modern: Is somewhat more recent (announced 7 months after the X-T20).
Arguments in favor of the Fujifilm X-T20:
- More detail: Has more megapixels (24 vs 15.9MP), which boosts linear resolution by 25%.
- Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
- More heavily discounted: Has been on the market for longer (launched in January 2017).
If the number of relative strengths (bullet points above) is taken as a guide, the match-up finishes in a tie (3 points each). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the E-M10 III or the X-T20. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. This is why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price 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.
