Panasonic GX8 versus Panasonic GX80
The Panasonic Lumix DMC-GX8 and the Panasonic Lumix DMC-GX80 (labelled Panasonic GX85 in some countries) are two digital cameras that were revealed to the public, respectively, in July 2015 and April 2016. Both the GX8 and the GX80 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The GX8 has a resolution of 20.2 megapixel, whereas the GX80 provides 15.8 MP.
The side-by-side display below illustrates the physical size and weight of the Panasonic GX8 and the Panasonic GX80. 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. 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 GX8 – 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 GX80 is notably smaller (17 percent) than the Panasonic GX8. Moreover, the GX80 is markedly lighter (13 percent) than the GX8. It is worth mentioning in this context that the GX8 is splash and dust resistant, while the GX80 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. 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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The GX80 was launched at a markedly lower price (by 33 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 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies 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 GX8 offers a higher resolution of 20.2 megapixel, compared with 15.8 MP of the GX80. This megapixel advantage translates into a 13 percent gain in linear resolution. On the other hand, these sensor specs imply that the GX8 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 3.77μm for the GX80). Moreover, it should be noted that the GX80 is a somewhat more recent model (by 8 months) than the GX8, 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 the GX80 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 GX8 has a notably higher overall DXO score than the GX80 (overall score 4 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.6 bits higher color depth, and 0.3 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 are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (4K/30p).
Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the GX80 offers a higher resolution than the one in the GX8 (2765k vs 2360k dots). The following table reports on some other key feature differences and similarities of the Panasonic GX8, the Panasonic GX80, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

The GX80 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.
So what is the bottom line? Is the Panasonic GX8 better than the Panasonic GX80 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Panasonic Lumix DMC-GX8:
- More detail: Offers more megapixels (20.2 vs 15.8MP) with a 13% higher linear resolution.
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
- 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.
- Faster burst: Shoots at higher frequency (10 vs 8 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (330 versus 290) on a single battery charge.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- More heavily discounted: Has been on the market for longer (launched in July 2015).
Arguments in favor of the Panasonic Lumix DMC-GX80:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- More detailed viewfinder: Has higher resolution electronic viewfinder (2765k vs 2360k dots).
- More compact: Is smaller (122x71mm vs 133x78mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 61g or 13 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 (33 percent cheaper at launch).
- More modern: Was introduced somewhat (8 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the GX8 emerges as the winner of the contest (9 : 7 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.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the GX8 or the GX80. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is why hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular 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 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
