Sony A6000 versus Panasonic GX800

The Sony Alpha A6000 and the Panasonic Lumix DMC-GX800 (labelled Panasonic GX850 in some countries) are two digital cameras that were announced, respectively, in February 2014 and January 2017. Both the A6000 and the GX800 are mirrorless interchangeable lens cameras that are based on an APS-C (A6000) and a Four Thirds (GX800) 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 GX800

The side-by-side display below illustrates the physical size and weight of the Sony A6000 and the Panasonic GX800. 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 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 side – the A6000 – 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 Panasonic GX800 is notably smaller (13 percent) than the Sony A6000. Moreover, the GX800 is markedly lighter (22 percent) than the A6000. In this context, it is worth noting that neither the A6000 nor the GX800 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 (GX800). 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.

Concerning battery life, the A6000 gets 360 shots out of its NP-FW50 battery, while the GX800 can take 210 images on a single charge of its DMW-BLH7 power pack.

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 GX800 was somewhat cheaper (by 8 percent) than the A6000 at launch, but both cameras fall into the same price category. 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 GX800

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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Sony A6000 features an APS-C sensor and the Panasonic GX800 a Four Thirds sensor. The sensor area in the GX800 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 GX800 offers a 4:3 aspect.

Sony A6000 and Panasonic GX800 sensor measures

With 24MP, the A6000 offers a higher resolution than the GX800 (15.8MP), but the A6000 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 3.77μm for the GX800) due to its larger sensor. However, the GX800 is a somewhat more recent model (by 2 years and 10 months) 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 GX800 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

A6000 versus GX800 MP

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"). Of the two cameras under review, the A6000 has a notably higher overall DXO score than the GX800 (overall score 9 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.9 bits higher color depth, 0.2 EV of lower dynamic range, and 1.2 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

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 GX800 provides a better video resolution than the A6000. It can shoot movie footage at 4K/30p, while the Sony is limited to 1080/60p.

 

Feature comparison: Sony A6000 vs Panasonic GX800

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A6000 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GX800 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Sony A6000 and Panasonic GX800 along with similar information for a selection of comparators. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

ilogo

Advantages of the Panasonic Lumix DMC-GX800:

  • 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 1080/60p).
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More compact: Is smaller (107x65mm vs 120x67mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 75g or 22 percent) and is thus easier to take along.
  • More modern: Reflects 2 years and 10 months of technical progress since the A6000 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the A6000 comes out slightly ahead of the GX800 (8 : 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.

A6000 08:07 GX800

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the A6000 and the GX800 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 expert reviews are important. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. 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.
