Canon G7 X Mark III vs Sony H400
The Canon PowerShot G7 X Mark III and the Sony Cyber-shot DSC-H400 are two digital cameras that were officially introduced, respectively, in July 2019 and February 2014. Both the G7X Mark III and the H400 are fixed lens compact cameras that are based on an one-inch (G7X Mark III) and a 1/2.3-inch (H400) sensor. The Canon has a resolution of 20 megapixels, whereas the Sony provides 19.9 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 Sony Cyber-shot DSC-H400? 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.
An illustration of the physical size and weight of the Canon G7 X Mark III and the Sony H400 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.
The G7X Mark III can be obtained in two different colors (black, silver), while the H400 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 Sony H400 is considerably larger (93 percent) than the Canon G7 X Mark III. Moreover, the H400 is substantially heavier (107 percent) than the G7X Mark III. In this context, it is worth noting that neither the G7X Mark III nor the H400 are weather-sealed.
Concerning battery life, the G7X Mark III gets 235 shots out of its NB-13L battery, while the H400 can take 300 images on a single charge of its NP-BX1 power pack. 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The price is, of course, an important factor in any camera decision. 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 H400 was launched at a markedly lower price (by 57 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 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 Sony H400 a 1/2.3-inch sensor. The sensor area in the H400 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 H400 offers a 4:3 aspect.
With 20MP, the G7X Mark III offers a slightly higher resolution than the H400 (19.9MP), but the G7X Mark III nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 1.19μm for the H400) due to its larger sensor. Moreover, the G7X Mark III is a much more recent model (by 5 years and 4 months) than the H400, 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 H400 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
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 Sony Cyber-shot DSC-H400 are ISO 80 to ISO 3200 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many 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 have a sensor with sufficiently fast read-out times for moving pictures, but the G7X Mark III provides a higher video resolution than the H400. It can shoot video footage at 4K/30p, while the Sony is limited to 720/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the H400 has an electronic viewfinder (210k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G7X Mark III relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon G7 X Mark III, the Sony H400, and comparable 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 H400 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 H400 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 H400 have zoom lenses built in. The G7X Mark III has a 24-100mm f/1.8-2.8 optic and the H400 offers a 24.5-1550mm f/3.4-6.5 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end than the Sony, but less tele-photo reach at the long end. The G7X Mark III offers the faster maximum aperture.
The G7X Mark III writes its imaging data to SDXC cards, while the H400 uses SDXC or Memory Stick PRO Duo cards. The G7X Mark III supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the H400 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 Sony Cyber-shot DSC-H400 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 H400. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Both the G7X Mark III and the H400 are recent models that are part of the current product line-up. The H400 replaced the earlier Sony H200, while the G7X Mark III followed on from the Canon G7X Mark II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Sony websites.

- More heavily discounted: Has been around for much longer (launched in February 2014).
If the count of individual advantages (bullet points above) is taken as a guide, the G7X Mark III is the clear winner of the match-up (23 : 6 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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.
How about other alternatives? Do the specifications of the Canon G7 X Mark III and the Sony H400 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Superzoom 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 remains incomplete and does no justice, for example, to the way the G7X Mark III or the H400 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 where reviews by experts come in. 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.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
