Canon G7 X vs G9X
The Canon PowerShot G7 X and the Canon PowerShot G9 X are two digital cameras that were revealed to the public, respectively, in September 2014 and October 2015. Both the G7X and the G9X 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 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.
The side-by-side display below illustrates the physical size and weight of the Canon G7 X and the Canon G9 X. 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 measures are rounded to the nearest millimeter.
The G9X can be obtained in two different colors (black, silver), while the G7X 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 (8 percent) than the Canon G7 X. Moreover, the G9X is markedly lighter (31 percent) than the G7X. In this context, it is worth noting that neither the G7X nor the G9X are weather-sealed.
The power pack in the G9X can be charged via the USB port, which can be very convenient when travelling.

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, 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.
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. 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 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 megapixels. This similarity in sensor specs implies that both the G7X and the G9X have the same pixel density, as well as the same pixel size. It should, however, be noted that the G9X is a somewhat more recent model (by 1 year) than the G7X, and its sensor might have benefitted from technological advances during this time.
The Canon PowerShot G7 X has a native sensitivity range from ISO 125 to ISO 12800. The Canon PowerShot G9 X offers exactly the same ISO settings.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under review, the G7X has a notably higher overall DXO score than the G9X (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.5 bits higher color depth, 0.4 EV in additional dynamic range, and 0.2 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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).
Apart from body and sensor, cameras can and do differ across a variety of features. The G7X 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 and Canon G9 X in connection with corresponding information for a sample of similar cameras.

The Canon G7 X 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 and the G9X have zoom lenses built in. The G7X 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 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 offers the faster maximum aperture.
Concerning the storage of imaging data, both the G7X 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.
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 and Canon PowerShot G9 X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the G7X and the G9X have been discontinued, but can regularly be found used on eBay. The G7X was replaced by the Canon G7 X Mark II, while the G9X was followed by the Canon G9 X Mark II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what is the bottom line? Which of the two cameras – the Canon G7 X or the Canon G9 X – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Canon PowerShot G7 X:
- Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.5 bits more color depth).
- 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.
- 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.
- More heavily discounted: Has been on the market for longer (launched in September 2014).
Reasons to prefer the Canon PowerShot G9 X:
- Less heavy: Has a lower weight (by 95g or 31 percent) and is thus easier to take along.
- Easier travel charging: Can be conveniently charged via its USB port.
- More affordable: Was released into a lower priced segment (24 percent cheaper at launch).
- More modern: Was introduced somewhat (1 year) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the G7X is the clear winner of the match-up (8 : 4 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. 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.
How about other alternatives? Do the specifications of the Canon G7 X 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 or the G9X. 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 following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.
