Canon G7 X Mark II vs Panasonic GX8
The Canon PowerShot G7 X Mark II and the Panasonic Lumix DMC-GX8 are two digital cameras that were revealed to the public, respectively, in February 2016 and July 2015. The G7X Mark II is a fixed lens compact, while the GX8 is a mirrorless interchangeable lens camera. The cameras are based on an one-inch (G7X Mark II) and a Four Thirds (GX8) sensor. The Canon has a resolution of 20 megapixels, whereas the Panasonic provides 20.2 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G7 X Mark II and the Panasonic Lumix DMC-GX8? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
The physical size and weight of the Canon G7 X Mark II and the Panasonic GX8 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.
The GX8 can be obtained in two different colors (black, silver), while the G7X Mark II is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GX8 is considerably larger (60 percent) than the Canon G7 X Mark II. It is noteworthy in this context that the GX8 is splash and dust-proof, while the G7X Mark II does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G7X Mark II has a lens built in, whereas the GX8 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the GX8 and their specifications in the Micro Four Thirds Lens Catalog.
Concerning battery life, the G7X Mark II gets 265 shots out of its NB-13L battery, while the GX8 can take 330 images on a single charge of its DMW-BLC12 power pack. The power pack in the G7X Mark II can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The G7X Mark II was launched at a lower price than the GX8, despite having a lens built in. 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.
Of the two cameras under consideration, the Canon G7 X Mark II features an one-inch sensor and the Panasonic GX8 a Four Thirds sensor. The sensor area in the GX8 is 94 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 2.0. The sensor in the G7X Mark II has a native 3:2 aspect ratio, while the one in the GX8 offers a 4:3 aspect.
With 20.2MP, the GX8 offers a higher resolution than the G7X Mark II (20MP), but the GX8 nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 2.41μm for the G7X Mark II) due to its larger sensor. However, the G7X Mark II is a somewhat more recent model (by 7 months) than the GX8, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The Canon PowerShot G7 X Mark II has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 125-25600. The corresponding ISO settings for the Panasonic Lumix DMC-GX8 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
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"). 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the GX8 provides a better video resolution than the G7X Mark II. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the GX8 has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G7X Mark II relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon G7 X Mark II and Panasonic GX8 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The G7X Mark II has one, while the GX8 does not. While the built-in flash of the G7X Mark II is not very powerful, it can at times be useful as a fill-in light.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the GX8 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Canon G7 X Mark II and the Panasonic GX8 both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Concerning the storage of imaging data, both the G7X Mark II and the GX8 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon PowerShot G7 X Mark II and Panasonic Lumix DMC-GX8 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GX8 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The G7X Mark II does not feature such a mic input.
Both the G7X Mark II and the GX8 have been discontinued, but can regularly be found used on eBay. The GX8 was replaced by the Panasonic GX9, while the G7X Mark II was followed by the Canon G7 X Mark III. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Panasonic websites.
So what conclusions can be drawn? Is the Canon G7 X Mark II better than the Panasonic GX8 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Canon PowerShot G7 X Mark II:

- More heavily discounted: Has been on the market for longer (launched in July 2015).
If the number of relative strengths (bullet points above) is taken as a guide, the GX8 is the clear winner of the contest (16 : 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. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Canon G7 X Mark II and the Panasonic GX8 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the G7X Mark II and the GX8 in practical situations. 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 summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
