Sony A6000 versus Panasonic GX85
The Sony Alpha A6000 and the Panasonic Lumix DMC-GX85 (labelled Panasonic GX80 in some countries) are two digital cameras that were officially introduced, respectively, in February 2014 and April 2016. Both the A6000 and the GX85 are mirrorless interchangeable lens cameras that are based on an APS-C (A6000) and a Four Thirds (GX85) sensor. The Sony has a resolution of 24 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: Sony A6000 vs Panasonic GX85
An illustration of the physical size and weight of the Sony A6000 and the Panasonic GX85 is provided 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 – the A6000 – 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 GX85 is notably larger (8 percent) than the Sony A6000. Moreover, the GX85 is markedly heavier (24 percent) than the A6000. In this context, it is worth noting that neither the A6000 nor the GX85 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can find an overview of optics for the two cameras in the Sony E-Mount Lens Catalog (A6000) and the Micro Four Thirds Lens Catalog (GX85). 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 A6000 was launched at a somewhat lower price (by 25 percent) than the GX85, which makes it more attractive for photographers on a tight budget. 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: Sony A6000 vs Panasonic GX85
The size of the imaging sensor is a crucial determinant 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.
Of the two cameras under consideration, the Sony A6000 features an APS-C sensor and the Panasonic GX85 a Four Thirds sensor. The sensor area in the GX85 is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the A6000 has a native 3:2 aspect ratio, while the one in the GX85 offers a 4:3 aspect.
With 24MP, the A6000 offers a higher resolution than the GX85 (15.8MP), but the A6000 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 3.77μm for the GX85) due to its larger sensor. However, the GX85 is a somewhat more recent model (by 2 years and 1 month) than the A6000, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the GX85 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 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"). Of the two cameras under review, the A6000 provides substantially higher image quality than the GX85, with an overall score that is 11 points higher. This advantage is based on 1.2 bits higher color depth, 0.5 EV in additional dynamic range, and 1 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

If the number of relative strengths (bullet points above) is taken as a guide, the A6000 emerges as the winner of the contest (10 : 7 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 before making a decision on a new camera.
In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the A6000 or the GX85 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 expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major 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.

The review scores listed above should be treated with care, 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.
