Panasonic GX80 versus Panasonic G9
The Panasonic Lumix DMC-GX80 (called Panasonic GX85 in some regions) and the Panasonic Lumix DC-G9 are two digital cameras that were announced, respectively, in April 2016 and November 2017. Both the GX80 and the G9 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The GX80 has a resolution of 15.8 megapixel, whereas the G9 provides 20.2 MP.
The side-by-side display below illustrates the physical size and weight of the Panasonic GX80 and the Panasonic G9. 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 side – the GX80 – 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 G9 is considerably larger (53 percent) than the Panasonic GX80. Moreover, the G9 is substantially heavier (54 percent) than the GX80. It is noteworthy in this context that the G9 is splash and dust-proof, 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 53 percent) than the G9, 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. 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.
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 G9 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 G9 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). However, it should be noted that the G9 is a somewhat more recent model (by 1 year and 7 months) than the GX80, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.
Unlike the GX80, the G9 has the capacity to capture high quality composite images (80.6MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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. 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the G9 provides a faster frame rate than the GX80. It can shoot movie footage at 4K/60p, while the GX80 is limited to 4K/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the G9 offers a higher resolution than the one in the GX80 (3680k vs 2765k dots). The following table reports on some other key feature differences and similarities of the Panasonic GX80, the Panasonic G9, and comparable cameras.

Both the GX80 and the G9 are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The GX80 replaced the earlier Panasonic GX7, while the G9 followed on from the Panasonic G85.
So what is the bottom line? Is there a clear favorite between the Panasonic GX80 and the Panasonic GX80? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Panasonic Lumix DMC-GX80:
- More compact: Is smaller (122x71mm vs 137x97mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 232g or 35 percent) and hence easier to carry around.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More affordable: Was introduced into a lower priced category (53 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in April 2016).
Advantages of the Panasonic Lumix DC-G9:
- More detail: Has more megapixels (20.2 vs 15.8MP), which boosts linear resolution by 13%.
- High quality composites: Can combine several shots after pixel-shifting its sensor.
- Better video: Provides higher movie framerates (4K/60p vs 4K/30p).
- More detailed viewfinder: Has a higher resolution electronic viewfinder (3680k vs 2765k dots).
- Easier setting verification: Has a control panel on top to check shooting parameters.
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Faster shutter: Has a higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
- Faster burst: Shoots at higher frequency (20 vs 8 flaps/sec) to capture the decisive moment.
- Longer lasting: Gets more shots (400 versus 290) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- More modern: Was introduced somewhat (1 year and 7 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the G9 is the clear winner of the contest (11 : 5 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 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 GX80 and the G9 in practical situations. 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 where reviews by experts come in. The table below summarizes the assessments of some of the best known 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 assessments were made in relation to similar cameras of the same technological generation. 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, please note that some of the review sites have changed their methodology and reporting over time.
