Any camera decision will obviously take relative prices into account. 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 III was launched at a somewhat lower price (by 17 percent) than the G5X Mark II, which makes it more attractive for photographers on a tight budget. 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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 are more costly to manufacture and tend to 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.

Canon G5 X Mark II and Canon G7 X Mark III sensor measures

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 G5X Mark II and the G7X Mark III have the same pixel density, as well as the same pixel size. Moreover, the two cameras were released in close succession, so that their sensors are from the same technological generation.

The Canon PowerShot G5 X Mark II has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 125-25600. The Canon PowerShot G7 X Mark III offers exactly the same ISO settings.

Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the G5X Mark II has an electronic viewfinder (2360k 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 table below summarizes some of the other core capabilities of the Canon G5 X Mark II and Canon G7 X Mark III in connection with corresponding information for a sample of similar cameras.

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 G5 X Mark II and the Canon G7 X Mark III 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 G5X Mark II and the G7X Mark III have zoom lenses built in. The G5X Mark II has a 24-120mm f/1.8-2.8 optic and the G7X Mark III offers a 24-100mm f/1.8-2.8 (focal lengths in full frame equivalent terms). Hence, the G5X Mark II and G7X Mark III provide the same view at the wide-angle end, but the G7X Mark III has less tele-photo reach at the long end. Both cameras offer the same maximum aperture.

Concerning the storage of imaging data, both the G5X Mark II and the G7X Mark III 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.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon G5 X Mark II and the Canon G7 X Mark III? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.


Advantages of the Canon PowerShot G5 X Mark II:

  • Easier framing: Has an electronic viewfinder for image composition and settings control.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.


Reasons to prefer the Canon PowerShot G7 X Mark III:

  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Less heavy: Has a lower weight (by 36g or 11 percent) and is thus easier to take along.
  • More affordable: Was released into a lower priced segment (17 percent cheaper at launch).

If the count of relative strengths (bullet points above) is taken as a measure, the G7X Mark III comes out slightly ahead of the G5X Mark II (3 : 2 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 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.

G5X Mark II 02:03 G7X Mark III

How about other alternatives? Do the specifications of the Canon G5 X Mark II and the Canon G7 X Mark III 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 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 G5X Mark II or the G7X Mark III 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.

Expert reviews

This is why hands-on reviews by experts 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], digitalcameraworld [DCW], 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 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
