Sony A6500 versus Panasonic GX8
The Sony Alpha A6500 and the Panasonic Lumix DMC-GX8 are two enthusiast cameras that were revealed to the public, respectively, in October 2016 and July 2015. Both the A6500 and the GX8 are mirrorless interchangeable lens cameras that are based on an APS-C (A6500) and a Four Thirds (GX8) sensor. The Sony has a resolution of 24 megapixel, whereas the Panasonic provides 20.2 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 A6500 vs Panasonic GX8
An illustration of the physical size and weight of the Sony A6500 and the Panasonic GX8 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 dimensions 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 A6500 – represents 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 GX8 is notably larger (29 percent) than the Sony A6500. Moreover, the GX8 is markedly heavier (8 percent) than the A6500. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.
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 (A6500) and the Micro Four Thirds Lens Catalog (GX8). 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 GX8 was launched at a somewhat lower price (by 14 percent) than the A6500, 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 A6500 vs Panasonic GX8
The size of the sensor inside a digital camera is one of the key determinants 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. 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 A6500 features an APS-C sensor and the Panasonic GX8 a Four Thirds sensor. The sensor area in the GX8 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 A6500 has a native 3:2 aspect ratio, while the one in the GX8 offers a 4:3 aspect.
With 24MP, the A6500 offers a higher resolution than the GX8 (20.2MP), but the A6500 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 3.34μm for the GX8) due to its larger sensor. Moreover, the A6500 is a somewhat more recent model (by 1 year and 2 months) than the GX8, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under review, the A6500 has a notably higher overall DXO score than the GX8 (overall score 10 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1 bits higher color depth, 1.1 EV in additional dynamic range, and 0.8 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.

The A6500 is a current model that online retailers, such as amazon, will have in stock. In contrast, the GX8 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the GX8 was succeeded by the Panasonic GX9.
Review summary: Sony A6500 vs Panasonic GX8
So how do things add up? Which of the two cameras – the Sony A6500 or the Panasonic GX8 – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Sony Alpha A6500:
- More detail: Offers more megapixels (24 vs 20.2MP) with a 11% higher linear resolution.
- Better image quality: Scores markedly higher (10 points) in the DXO overall assessment.
- More dynamic range: Captures a larger spectrum of light and dark details (1.1 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (0.8 stops ISO advantage).
- More compact: Is smaller (120x67mm vs 133x78mm) and thus needs less room in the bag.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More modern: Is somewhat more recent (announced 1 year and 2 months after the GX8).
Arguments in favor of the Panasonic Lumix DMC-GX8:
- More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
- More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
- Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
- More affordable: Was released into a lower priced segment (14 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in July 2015).
If the count of relative strengths (bullet points above) is taken as a measure, the A6500 emerges as the winner of the contest (7 : 5 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 A6500 or the GX8 handle or perform in practice. 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.

Care should be taken when interpreting the review scores above, 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
