Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

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 HX400V was launched at a markedly lower price (by 33 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.

Sensor comparison

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 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 Sony HX400V a 1/2.3-inch sensor. The sensor area in the HX400V 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 HX400V offers a 4:3 aspect.

Canon G7 X Mark III and Sony HX400V sensor measures

Despite having a smaller sensor, the HX400V offers a slightly higher resolution of 20.2 megapixels, compared with 20 MP of the G7X Mark III. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.18μm versus 2.41μm for the G7X Mark III). Moreover, it should be noted that the G7X Mark III is much more recent (by 5 years and 4 months) than the HX400V, 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 HX400V 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-HX400V are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-12800.

G7X Mark III versus HX400V MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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").

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G7X Mark III has a touchscreen, while the HX400V 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 HX400V 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 HX400V have zoom lenses built in. The G7X Mark III has a 24-100mm f/1.8-2.8 optic and the HX400V offers a 24-1200mm f/2.8-6.3 (focal lengths in full frame equivalent terms). Hence, the Canon and Sony provide the same view at the wide-angle end, but the Sony has more 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 HX400V 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 HX400V cannot take advantage of Ultra High Speed SD cards.

It is notable that the G7X Mark III has a microphone port, which is missing on the HX400V. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Travel and landscape photographers will find it useful that the HX400V has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the G7X Mark III and the HX400V are recent models that are part of the current product line-up. The G7X Mark III replaced the earlier Canon G7X Mark II, while the HX400V does not have a direct predecessor. 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.



Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon G7 X Mark III or the Sony HX400V – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

If the count of relative strengths (bullet points above) is taken as a measure, the G7X Mark III is the clear winner of the match-up (20 : 10 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.

G7X Mark III 20:10 HX400V

How about other alternatives? Do the specifications of the Canon G7 X Mark III and the Sony HX400V 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 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 HX400V 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.

Expert reviews

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 (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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
