Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G7 X Mark II and the Canon PowerShot G9 X? 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.

Body comparison

An illustration of the physical size and weight of the Canon G7 X Mark II and the Canon G9 X is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

The G9X can be obtained in two different colors (black, silver), while the G7X Mark II 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 Canon G9 X is notably smaller (12 percent) than the Canon G7 X Mark II. Moreover, the G9X is markedly lighter (34 percent) than the G7X Mark II. In this context, it is worth noting that neither the G7X Mark II nor the G9X are weather-sealed.

The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will naturally be influenced heavily by the price. 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 G9X was launched at a somewhat lower price (by 24 percent) than the G7X Mark II, which makes it more attractive for photographers on a tight budget. 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 size of the sensor inside a digital camera is one of the key determinants 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the 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 chip-set technology, the G7X Mark II uses a more advanced image processing engine (DIGIC 7) than the G9X (DIGIC 6), with benefits for noise reduction, color accuracy, and processing speed.

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 II and the G9X have the same pixel density, as well as the same pixel size. It should, however, be noted that the G7X Mark II is a somewhat more recent model (by 4 months) than the G9X, and its sensor might have benefitted from technological advances during this time.

The Canon PowerShot G7 X Mark II 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 Canon PowerShot G9 X are ISO 125 to ISO 12800 (no boost).

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.

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.

The G7X Mark II 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 G9X does not have a selfie-screen.

The Canon G7 X Mark II and the Canon G9 X 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 II and the G9X have zoom lenses built in. The G7X Mark II has a 24-100mm f/1.8-2.8 optic and the G9X offers a 28-84mm f/2.0-4.9 (focal lengths in full frame equivalent terms). Hence, the G7X Mark II provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the G9X. The G7X Mark II offers the faster maximum aperture.

Concerning the storage of imaging data, both the G7X Mark II and the G9X 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.

Connectivity comparison

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 II and Canon PowerShot G9 X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Review summary

So how do things add up? Is the Canon G7 X Mark II better than the Canon G9 X or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon PowerShot G7 X Mark II:

• Better jpgs: Has a more modern image processing engine (DIGIC 7 vs DIGIC 6).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (8 vs 6 flaps/sec) to capture the decisive moment.
• Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/2.0).
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Longer lasting: Can take more shots (265 versus 220) on a single battery charge.
• More modern: Is somewhat more recent (announced 4 months after the G9X).

Arguments in favor of the Canon PowerShot G9 X:

• More compact: Is smaller (98x58mm vs 106x61mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 110g or 34 percent) and is thus easier to take along.
• More affordable: Was released into a lower priced segment (24 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in October 2015).

If the number of relative strengths (bullet points above) is taken as a guide, the G7X Mark II is the clear winner of the match-up (9 : 4 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.

How about other alternatives? Do the specifications of the Canon G7 X Mark II and the Canon G9 X 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G7X Mark II or the G9X. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

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], 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 are only valid when referring to cameras in the same category and of the same age. 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.
