Canon G7 X Mark II versus Canon G9 X
The Canon PowerShot G7 X Mark II and the Canon PowerShot G9 X are two digital cameras that were officially introduced, respectively, in February 2016 and October 2015. Both the G7X Mark II and the G9X are fixed lens compact cameras that are equipped with an one-inch sensor. Both cameras offer a resolution of 20 megapixel. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.
Body comparison: Canon G7 X Mark II vs Canon G9 X
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. Three consecutive perspectives from the front, the top, and the back are presented. All size dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the G7X Mark II – represents the basis or 100 percent across all the size and weight measures).
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 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, just select a new right or left comparator from among the camera models in the table.

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 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison: Canon G7 X Mark II vs Canon G9 X
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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies 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.
The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 20 megapixel. 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.
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"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. 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 (1080/60p).
Feature comparison: Canon G7 X Mark II vs Canon G9 X
Beyond body and sensor, cameras can and do differ across a range of features. The G7X Mark II and the G9X 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 table below summarizes some of the other core capabilities of the Canon G7 X Mark II and Canon G9 X in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the G7X Mark II and the G9X have zoom lenses build 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.
The G7X Mark II is a current model that online retailers, such as amazon, will have in stock. In contrast, the G9X has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the G9X was succeeded by the Canon G9 X Mark II.
Review summary: Canon G7 X Mark II vs Canon G9 X
So what is the bottom line? Which of the two cameras – the Canon G7 X Mark II or the Canon G9 X – has the upper hand? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Canon PowerShot G7 X Mark II:
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- 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).
Advantages 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 count of individual advantages (bullet points above) is taken as a guide, the G7X Mark II emerges as the winner of the contest (7 : 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.
In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the G7X Mark II or the G9X handle or 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 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
