Canon G9 X versus Canon G7 X Mark II

The Canon PowerShot G9 X and the Canon PowerShot G7 X Mark II are two digital cameras that were announced, respectively, in October 2015 and February 2016. Both the G9X and the G7X Mark II 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 G9 X vs Canon G7 X Mark II

An illustration of the physical size and weight of the Canon G9 X and the Canon G7 X Mark II is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures 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 G9X – 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 G7 X Mark II is notably larger (14 percent) than the Canon G9 X. Moreover, the G7X Mark II is substantially heavier (53 percent) than the G9X. In this context, it is worth noting that neither the G9X nor the G7X Mark II 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. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 G9 X vs Canon G7 X Mark II

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. 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 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 G9 X and Canon G7 X Mark II sensor measures

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 G9X and the G7X Mark II 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.

For most cameras, data on sensor performance has been reported by DXO Mark. 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").

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60p).

Feature comparison: Canon G9 X vs Canon G7 X Mark II

Beyond body and sensor, cameras can and do differ across a range of features. The G9X and the G7X Mark II 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 G9 X and Canon G7 X Mark II in connection with corresponding information for a sample of similar cameras.

Both the G9X and the G7X Mark II have zoom lenses build in. The G9X has a 28-84mm f/2.0-4.9 optic and the G7X Mark II offers a 24-100mm f/1.8-2.8 (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 G9 X vs Canon G7 X Mark II

So what conclusions can be drawn? Is the Canon G9 X better than the Canon G7 X Mark II or vice versa? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Canon PowerShot G9 X:

  • More compact: Is smaller (98x58mm vs 106x61mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 110g or 34 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced segment (24 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in October 2015).

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: Gets more shots (265 versus 220) out of a single battery charge.
  • More modern: Was introduced somewhat (4 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the G7X Mark II emerges as the winner of the match-up (7 : 4 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.

G9X 04:07 G7X Mark II

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the G9X or the G7X Mark II. 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. This is why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
