Olympus E-M10 III versus Olympus E-M5
The Olympus OM-D E-M10 Mark III and the Olympus OM-D E-M5 are two digital cameras that were officially introduced, respectively, in August 2017 and February 2012. Both the E-M10 III and the E-M5 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. Both cameras offer a resolution of 15.9 megapixel.
The side-by-side display below illustrates the physical size and weight of the Olympus E-M10 III and the Olympus E-M5. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter. You can also toggle the display 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 – 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 Olympus E-M5 is considerably larger (106 percent) than the Olympus E-M10 III. Moreover, the E-M5 is slightly heavier (4 percent) than the E-M10 III. It is noteworthy in this context that the E-M5 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. 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 launched at a markedly lower price (by 50 percent) than the E-M5, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 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.
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-M5 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 5 years and 6 months) than the E-M5, and its sensor will have benefitted from technological advances during this time. 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.
For most cameras, data on sensor performance has been reported by DXO Mark. 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 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 cannot only take still pictures, but also record videos. 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-M5. It can shoot video footage at 4K/30p, while the E-M5 is limited to 1080/60i.
Apart from 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-M5 (2360k vs 1440k dots). The table below summarizes some of the other core capabilities of the Olympus E-M10 III and Olympus E-M5 in connection with corresponding information for a sample of similar cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

The E-M10 III is a current model that online retailers, such as amazon, will have in stock. In contrast, the E-M5 has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-M5 was succeeded by the Olympus E-M5 II.
So what conclusions can be drawn? Is the Olympus E-M10 III better than the Olympus E-M5 or vice versa? The listing below highlights the relative strengths of the two models.
Advantages of the Olympus OM-D E-M10 Mark III:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60i).
- More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
- More detailed LCD: Has a higher resolution rear screen (1040k vs 610k dots).
- More compact: Is smaller (122x84mm vs 122x89mm) and thus needs less room in the bag.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
- More modern: Reflects 5 years and 6 months of technical progress since the E-M5 launch.
Reasons to prefer the Olympus OM-D E-M5:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- More heavily discounted: Has been around for much longer (launched in February 2012).
If the number of relative strengths (bullet points above) is taken as a guide, the E-M10 III is the clear winner of the match-up (8 : 3 points). 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the E-M10 III or the E-M5 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 why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
