Canon G7 X Mark III vs Sony ZV-1
The Canon PowerShot G7 X Mark III and the Sony Cyber-shot ZV-1 are two digital cameras that were announced, respectively, in July 2019 and May 2020. Both the G7X Mark III and the ZV-1 are fixed lens compact cameras that are equipped with an one-inch sensor. Both cameras offer a resolution of 20 megapixels.
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 ZV-1? 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 Sony ZV-1 are illustrated 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 dimensions are rounded to the nearest millimeter.
The G7X Mark III can be obtained in two different colors (black, silver), while the ZV-1 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 ZV-1 is somewhat smaller (2 percent) than the Canon G7 X Mark III. Moreover, the ZV-1 is slightly lighter (3 percent) than the G7X Mark III. In this context, it is worth noting that neither the G7X Mark III nor the ZV-1 are weather-sealed.
Concerning battery life, the G7X Mark III gets 235 shots out of its NB-13L battery, while the ZV-1 can take 260 images on a single charge of its NP-BX1 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G7X Mark III was somewhat cheaper (by 6 percent) than the ZV-1 at launch, but both cameras fall into the same price category. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.
Both cameras under consideration feature an one-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 2.7. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
In terms of underlying technology, both cameras are build around BSI-CMOS sensors.
The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 20 megapixels. This similarity in sensor specs implies that both the G7X Mark III and the ZV-1 have the same pixel density, as well as the same pixel size. It should, however, be noted that the ZV-1 is a somewhat more recent model (by 10 months) than the G7X Mark III, and its sensor might have benefitted from technological advances during this time.
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 ZV-1 are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.
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 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 are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (4K/30p).
Apart from body and sensor, cameras can and do differ across a variety of features. The G7X Mark III and the ZV-1 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 adjacent table lists some of the other core features of the Canon G7 X Mark III and Sony ZV-1 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The G7X Mark III has one, while the ZV-1 does not. While the built-in flash of the G7X Mark III 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, both cameras under consideration feature an 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 and the Sony ZV-1 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.
Both the G7X Mark III and the ZV-1 have zoom lenses built in. The G7X Mark III has a 24-100mm f/1.8-2.8 optic and the ZV-1 offers a 24-70mm f/1.8-2.8 (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 less tele-photo reach at the long end. Both cameras offer the same maximum aperture.
The G7X Mark III writes its imaging data to SDXC cards, while the ZV-1 uses SDXC or Memory Stick PRO Duo 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 III and Sony Cyber-shot ZV-1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the ZV-1 has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The G7X Mark III does not feature such an accessory-socket.
Both the G7X Mark III and the ZV-1 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 ZV-1 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.
So what conclusions can be drawn? Is the Canon G7 X Mark III better than the Sony ZV-1 or vice versa? The listing below highlights the relative strengths of the two models.
Advantages of the Canon PowerShot G7 X Mark III:
- More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
- Faster burst: Shoots at higher frequency (30 vs 24 flaps/sec) to capture the decisive moment.
- More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
- More heavily discounted: Has been on the market for longer (launched in July 2019).
Arguments in favor of the Sony Cyber-shot ZV-1:
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Longer lasting: Gets more shots (260 versus 235) out of a single battery charge.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- More modern: Was introduced somewhat (10 months) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the G7X Mark III comes out slightly ahead of the ZV-1 (6 : 5 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 ZV-1 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the G7X Mark III or the ZV-1 perform in practice. 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 expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 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, please note that some of the review sites have changed their methodology and reporting over time.
