Canon G7 X Mark III vs Nikon B500
The Canon PowerShot G7 X Mark III and the Nikon Coolpix B500 are two digital cameras that were officially introduced, respectively, in July 2019 and January 2016. Both the G7X Mark III and the B500 are fixed lens compact cameras that are based on an one-inch (G7X Mark III) and a 1/2.3-inch (B500) sensor. The Canon has a resolution of 20 megapixels, whereas the Nikon provides 15.9 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 III and the Nikon Coolpix B500? 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 III and the Nikon B500 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 G7X Mark III can be obtained in two different colors (black, silver), while the B500 is also available in two color-versions, but different ones (black, red).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon B500 is notably larger (39 percent) than the Canon G7 X Mark III. Moreover, the B500 is substantially heavier (78 percent) than the G7X Mark III. In this context, it is worth noting that neither the G7X Mark III nor the B500 are weather-sealed.
The power pack in the G7X Mark III can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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 B500 was launched at a markedly lower price (by 60 percent) than the G7X Mark III, 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.
Of the two cameras under consideration, the Canon G7 X Mark III features an one-inch sensor and the Nikon B500 a 1/2.3-inch sensor. The sensor area in the B500 is 76 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 5.6. The sensor in the G7X Mark III has a native 3:2 aspect ratio, while the one in the B500 offers a 4:3 aspect.
With 20MP, the G7X Mark III offers a higher resolution than the B500 (15.9MP), but the G7X Mark III nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 1.33μm for the B500) due to its larger sensor. Moreover, the G7X Mark III is a much more recent model (by 3 years and 5 months) than the B500, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the B500 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon G7 X Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G7X Mark III for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Nikon B500 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.
The Canon PowerShot G7 X Mark III 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 Nikon Coolpix B500 are ISO 80 to ISO 6400 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). 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 cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the G7X Mark III provides a higher video resolution than the B500. It can shoot video footage at 4K/30p, while the Nikon is limited to 1080/60i.
Apart from body and sensor, cameras can and do differ across a variety of features. The G7X Mark III and the B500 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. The table below summarizes some of the other core capabilities of the Canon G7 X Mark III and Nikon B500 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G7X Mark III has a touchscreen, while the B500 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G7X Mark III has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the B500 does not have a selfie-screen.
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 G7X Mark III 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 III has 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.
Both the G7X Mark III and the B500 have zoom lenses built in. The G7X Mark III has a 24-100mm f/1.8-2.8 optic and the B500 offers a 22.5-900mm f/3.0-6.5 (focal lengths in full frame equivalent terms). Hence, the Nikon provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Canon. The G7X Mark III offers the faster maximum aperture.
Concerning the storage of imaging data, both the G7X Mark III and the B500 write their files to SDXC cards. The G7X Mark III supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the B500 cannot take advantage of Ultra High Speed SD cards.
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 III and Nikon Coolpix B500 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G7X Mark III has a microphone port, which is missing on the B500. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
The G7X Mark III is a recent model that features in the current product line-up of Canon. In contrast, the B500 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the B500 was succeeded by the Nikon B600. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Nikon websites.

If the number of relative strengths (bullet points above) is taken as a guide, the G7X Mark III is the clear winner of the match-up (21 : 8 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the G7X Mark III or the B500 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 following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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.

Care should be taken when interpreting the review scores above, 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
