Olympus E-M10 III versus Olympus E-M10

The Olympus OM-D E-M10 Mark III and the Olympus OM-D E-M10 are two digital cameras that were announced, respectively, in August 2017 and January 2014. Both the E-M10 III and the E-M10 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. Both cameras offer a resolution of 15.9 megapixel.

Body comparison

The physical size and weight of the Olympus E-M10 III and the Olympus E-M10 are illustrated in the side-by-side display below. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the E-M10 III – represents the basis for the calculations 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 Olympus E-M10 is somewhat smaller (5 percent) than the Olympus E-M10 III. Moreover, the E-M10 is slightly lighter (3 percent) than the E-M10 III. In this context, it is worth noting that neither the E-M10 III nor the E-M10 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an overview of suitable optics in the Micro Four Thirds Lens Catalog. 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 somewhat cheaper (by 7 percent) than the E-M10 at launch, but both cameras fall into the same price category. 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

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 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Sensor size

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 15.9 megapixel. This similarity in sensor specs implies that both the E-M10 III and the E-M10 have the same pixel density, as well as the same pixel size. It should, however, be noted that the E-M10 III is much more recent (by 3 years and 7 months) than the E-M10, and its sensor will have benefitted from technological advances during this time. 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.

Sensor resolution

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the E-M10 III provides a higher video resolution than the E-M10. It can shoot video footage at 4K/30p, while the E-M10 is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the E-M10 III offers a substantially higher resolution than the one in the E-M10 (2360k vs 1440k dots). The table below summarizes some of the other core capabilities of the Olympus E-M10 III and Olympus E-M10 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.

The E-M10 III is a current model that online retailers, such as amazon, will have in stock. In contrast, the E-M10 has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-M10 was succeeded by the Olympus E-M10 II.

Summary

So what conclusions can be drawn? Is the Olympus E-M10 III better than the Olympus E-M10 or vice versa? The listing below highlights the relative strengths of the two models.


Reasons to prefer the Olympus OM-D E-M10 Mark III:

  • Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
  • More modern: Reflects 3 years and 7 months of technical progress since the E-M10 launch.

Advantages of the Olympus OM-D E-M10:

  • More heavily discounted: Has been around for much longer (launched in January 2014).

If the count of individual advantages (bullet points above) is taken as a guide, the E-M10 III emerges as the winner of the contest (3 : 1 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.

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 E-M10. 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 hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
