Panasonic GX800 versus Canon G1 X Mark III
The Panasonic Lumix DMC-GX800 (called Panasonic GX850 in some regions) and the Canon PowerShot G1 X Mark III are two digital cameras that were announced, respectively, in January 2017 and October 2017. The GX800 is a mirrorless interchangeable lens camera, while the G1X Mark III is a fixed lens compact. The cameras are based on a Four Thirds (GX800) and an APS-C sensor. The Panasonic has a resolution of 15.8 megapixel, whereas the Canon provides 24 MP.
An illustration of the physical size and weight of the Panasonic GX800 and the Canon G1 X Mark III is provided in the side-by-side display below. 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 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 GX800 – 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 Canon G1 X Mark III is notably larger (29 percent) than the Panasonic GX800. It is noteworthy in this context that the G1X Mark III is splash and dust-proof, while the GX800 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X Mark III has a lens build in, whereas the GX800 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the GX800 and their specifications in the Micro Four Thirds Lens Catalog.
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. 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixels 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Panasonic GX800 features a Four Thirds sensor and the Canon G1 X Mark III an APS-C sensor. The sensor area in the G1X Mark III is 48 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 GX800 has a native 4:3 aspect ratio, while the one in the G1X Mark III offers a 3:2 aspect.
With 24MP, the G1X Mark III offers a higher resolution than the GX800 (15.8MP), but the G1X Mark III has marginally smaller individual pixels (pixel pitch of 3.72μm versus 3.77μm for the GX800). Yet, the G1X Mark III is a somewhat more recent model (by 9 months) than the GX800, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. 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.
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"). 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 can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the GX800 provides a higher video resolution than the G1X Mark III. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the G1X Mark III has an electronic viewfinder (2360k 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 Panasonic GX800 and Canon G1 X Mark III along with similar information for a selection of comparators. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the GX800 and the G1X Mark III are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The GX800 replaced the earlier Panasonic GF7, while the G1X Mark III followed on from the Canon G1 X Mark II.
So how do things add up? Which of the two cameras – the Panasonic GX800 or the Canon G1 X Mark III – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor 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 flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- More compact: Is smaller (107x65mm vs 115x78mm) and thus needs less room in the bag.
- More heavily discounted: Has been on the market for longer (launched in January 2017).
Advantages of the Canon PowerShot G1 X Mark III:
- More detail: Has more megapixels (24 vs 15.8MP), which boosts linear resolution by 26%.
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better image quality: Is equipped with a larger and more technologically advanced sensor.
- Easier framing: Has an electronic viewfinder for image framing and settings control.
- More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
- Faster shutter: Has higher mechanical shutter speed (2000/sec vs 500/sec) to freeze action.
- Ready to shoot: Has an integrated lens, whereas the GX800 necessitates an extra lens.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
- More modern: Was introduced somewhat (9 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the G1X Mark III is the clear winner of the contest (10 : 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 remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the GX800 or the G1X Mark III. 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 adjacent table relays the overall verdicts of several of the most popular camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
