Panasonic GX8 versus Sony A6000
The Panasonic Lumix DMC-GX8 and the Sony Alpha A6000 are two enthusiast cameras that were officially introduced, respectively, in July 2015 and February 2014. Both the GX8 and the A6000 are mirrorless interchangeable lens cameras that are based on a Four Thirds (GX8) and an APS-C sensor. The Panasonic has a resolution of 20.2 megapixel, whereas the Sony provides 24 MP.
The physical size and weight of the Panasonic GX8 and the Sony A6000 are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. 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 – the GX8 – 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 Sony A6000 is notably smaller (22 percent) than the Panasonic GX8. Moreover, the A6000 is markedly lighter (29 percent) than the GX8. It is worth mentioning in this context that the GX8 is splash and dust resistant, while the A6000 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. 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 Micro Four Thirds Lens Catalog (GX8) and the Sony E-Mount Lens Catalog (A6000). 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 A6000 was launched at a markedly lower price (by 50 percent) than the GX8, 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 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. 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 are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Panasonic GX8 features a Four Thirds sensor and the Sony A6000 an APS-C sensor. The sensor area in the A6000 is 63 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the GX8 has a native 4:3 aspect ratio, while the one in the A6000 offers a 3:2 aspect.
With 24MP, the A6000 offers a higher resolution than the GX8 (20.2MP), but the A6000 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 3.34μm for the GX8) due to its larger sensor. However, the GX8 is a somewhat more recent model (by 1 year and 5 months) than the A6000, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
Consistent information on actual sensor performance is available from DXO Mark for most 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"). Of the two cameras under consideration, the A6000 has a markedly higher DXO score than the GX8 (overall score 7 points higher), which will translate into better image quality. The advantage is based on 0.6 bits higher color depth, 0.5 EV in additional dynamic range, and 0.7 stops in additional low light sensitivity. 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 GX8 provides a higher video resolution than the A6000. It can shoot video footage at 4K/30p, while the Sony is limited to 1080/60p.
Beyond 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 GX8 offers a substantially higher resolution than the one in the A6000 (2360k vs 1440k dots). The following table reports on some other key feature differences and similarities of the Panasonic GX8, the Sony A6000, and comparable cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

- Less heavy: Has a lower weight (by 143g or 29 percent) and is thus easier to take along.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in February 2014).
If the count of individual advantages (bullet points above) is taken as a guide, the GX8 comes out slightly ahead of the A6000 (9 : 8 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.
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 GX8 and the A6000 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. 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 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.
