Panasonic GX85 versus Olympus E-M10 II
The Panasonic Lumix DMC-GX85 (called Panasonic GX80 in some regions) and the Olympus OM-D E-M10 Mark II are two digital cameras that were officially introduced, respectively, in April 2016 and August 2015. Both the GX85 and the E-M10 II are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The Panasonic has a resolution of 15.8 megapixel, whereas the Olympus provides 15.9 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: Panasonic GX85 vs Olympus E-M10 II
An illustration of the physical size and weight of the Panasonic GX85 and the Olympus E-M10 II is provided 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. 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 side – the GX85 – 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 II is notably larger (15 percent) than the Panasonic GX85. However, the E-M10 II is markedly lighter (8 percent) than the GX85. In this context, it is worth noting that neither the GX85 nor the E-M10 II 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 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 two cameras under review were launched at the same price and fall into the same 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: Panasonic GX85 vs Olympus E-M10 II
The size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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.
While the two cameras under review share the same sensor size, the E-M10 II offers a slightly higher resolution of 15.9 megapixel, compared with 15.8 MP of the GX85. 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 II 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 GX85). Moreover, it should be noted, that the GX85 is a somewhat more recent model (by 7 months) than the E-M10 II, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels. 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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the GX85 provides a higher video resolution than the E-M10 II. It can shoot video footage at 4K/30p, while the Olympus is limited to 1080/60p.
Feature comparison: Panasonic GX85 vs Olympus E-M10 II

The GX85 is a current model that online retailers, such as amazon, will have in stock. In contrast, the E-M10 II has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-M10 II was succeeded by the Olympus E-M10 III.
Review summary: Panasonic GX85 vs Olympus E-M10 II
So what is the bottom line? Is the Panasonic GX85 better than the Olympus E-M10 II or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Panasonic Lumix DMC-GX85:
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- More detailed viewfinder: Has higher resolution electronic viewfinder (2765k vs 2360k dots).
- More compact: Is smaller (122x71mm vs 120x83mm) and thus needs less room in the bag.
- More modern: Is somewhat more recent (announced 7 months after the E-M10 II).
Arguments in favor of the Olympus OM-D E-M10 Mark II:
- Better low-light sensitivity: Can shoot in dim conditions (0.3 stops ISO advantage).
- Longer lasting: Gets more shots (320 versus 290) out of a single battery charge.
- More heavily discounted: Has been on the market for longer (launched in August 2015).
If the count of relative strengths (bullet points above) is taken as a measure, the GX85 comes out slightly ahead of the E-M10 II (4 : 3 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 when reflecting and deciding on a new camera.
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 GX85 and the E-M10 II in practical situations. 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 expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites. You can find the full text of the reviews, 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.
