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 revealed to the public, 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 (X-T20) sensor. The Olympus has a resolution of 15.9 megapixel, whereas the Fujifilm 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 Fujifilm X-T20

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. The two cameras are presented according to their relative size. 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 markedly 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.

Concerning battery life, the E-M10 III gets 330 shots out of its BLS-50 battery, while the X-T20 can take 350 images on a single charge of its NP-W126S power pack.

Any camera purchase will naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. 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.

 

Sensor comparison: Olympus E-M10 III vs Fujifilm X-T20

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies 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.

Olympus E-M10 III and Fujifilm X-T20 sensor measures

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.

E-M10 III versus X-T20 MP

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 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).

 

Feature comparison: Olympus E-M10 III vs Fujifilm X-T20

Beyond body and sensor, cameras can and do differ across a range 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 adjacent table lists some of the other core features of the Olympus E-M10 III and Fujifilm X-T20 along with similar information for a selection of comparators.

Review summary: Olympus E-M10 III vs Fujifilm X-T20

So what conclusions can be drawn? Is there a clear favorite between the Olympus E-M10 III and the Fujifilm X-T20? The listing below highlights the relative strengths of the two models.

ilogo

Arguments in favor of 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).

ilogo

Advantages 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 count of relative strengths (bullet points above) is taken as a measure, 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 before making a decision on a new camera.

E-M10 III 03:03 X-T20

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the E-M10 III or the X-T20 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 where reviews by experts come in.

The review scores listed above should be treated 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
