Olympus E-M10 III versus Panasonic G80

The Olympus OM-D E-M10 Mark III and the Panasonic Lumix DMC-G80 (labelled Panasonic G85 in some countries) are two digital cameras that were officially introduced, respectively, in August 2017 and September 2016. Both the E-M10 III and the G80 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The Olympus has a resolution of 15.9 megapixel, whereas the Panasonic provides 15.8 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 Panasonic G80

The physical size and weight of the Olympus E-M10 III and the Panasonic G80 are illustrated in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures 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 Panasonic G80 is notably larger (11 percent) than the Olympus E-M10 III. Moreover, the G80 is markedly heavier (23 percent) than the E-M10 III. It is noteworthy in this context that the G80 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 camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch 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 G80, 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.

 

Sensor comparison: Olympus E-M10 III vs Panasonic G80

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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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.

Olympus E-M10 III and Panasonic G80 sensor measures

While the two cameras under review share the same sensor size, the E-M10 III offers a slightly higher resolution of 15.9 megapixel, compared with 15.8 MP of the G80. This megapixel advantage translates into a 0.3 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-M10 III has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 3.77μm for the G80). In this context, it should be noted, however, that the E-M10 III is a somewhat more recent model (by 11 months) than the G80, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size. 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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").

Review summary: Olympus E-M10 III vs Panasonic G80

So what is the bottom line? Is the Olympus E-M10 III better than the Panasonic G80 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

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

  • Less heavy: Is lighter (by 95g or 19 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (28 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 11 months after the G80).

ilogo

Reasons to prefer the Panasonic Lumix DMC-G80:

  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More heavily discounted: Has been on the market for longer (launched in September 2016).

If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (3 points each). 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.

E-M10 III 03:03 G80

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the E-M10 III and the G80 in practical situations. 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 (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
