Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus OM-D E-M10 and the Olympus OM-D E-M10 Mark III? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison: Olympus E-M10 vs E-M10 III

An illustration of the physical size and weight of the Olympus E-M10 and the Olympus E-M10 III is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

Both cameras are available in two different colors (black, silver).

Compare E-M10 versus E-M10 III top
Comparison E-M10 or E-M10 III rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M10 III is somewhat larger (5 percent) than the Olympus E-M10. Moreover, the E-M10 III is slightly heavier (4 percent) than the E-M10. In this context, it is worth noting that neither the E-M10 nor the E-M10 III 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 compare the optics available 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.

Concerning battery life, the E-M10 gets 320 shots out of its BLS-5 battery, while the E-M10 III can take 330 images on a single charge of its BLS-50 power pack.

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.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

Any camera decision 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 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.

 

Sensor comparison: Olympus E-M10 vs E-M10 III

The size of the sensor inside a digital camera is one of the key determinants 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 tend to be more expensive and lead to bigger and heavier cameras 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.

Technology-wise, the E-M10 III uses a more advanced image processing engine (TruePic VIII) than the E-M10 (TruePic VII), with benefits for noise reduction, color accuracy, and processing speed.

Olympus E-M10 and Olympus E-M10 III sensor measures

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 15.9 megapixels. This similarity in sensor specs implies that both the E-M10 and the E-M10 III 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.

The Olympus OM-D E-M10 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The Olympus OM-D E-M10 Mark III offers exactly the same ISO settings.

The E-M10 III is a recent model that features in the current product line-up of Olympus. 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. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus website.


Review summary: Olympus E-M10 vs E-M10 III

So how do things add up? Is the Olympus E-M10 better than the Olympus E-M10 III 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:

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


Arguments in favor of the Olympus OM-D E-M10 Mark III:

  • Better jpgs: Has a more modern image processing engine (TruePic VIII vs TruePic VII).
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.62x vs 0.58x).
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More modern: Reflects 3 years and 7 months of technical progress since the E-M10 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the E-M10 III is the clear winner of the contest (6 : 1 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

E-M10 01:06 E-M10 III

How about other alternatives? Do the specifications of the Olympus E-M10 and the Olympus E-M10 III place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-M10 or the E-M10 III. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews: Olympus E-M10 vs E-M10 III

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

The review scores listed above should be treated with care, though. The ratings are only valid when referring 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
