Canon G9 X Mark II vs SX720
The Canon PowerShot G9 X Mark II and the Canon PowerShot SX720 HS are two digital cameras that were announced, respectively, in January 2017 and February 2016. Both the G9X Mark II and the SX720 are fixed lens compact cameras that are based on an one-inch (G9X Mark II) and a 1/2.3-inch (SX720) sensor. The G9X Mark II has a resolution of 20 megapixels, whereas the SX720 provides 20.2 MP.
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 G9 X Mark II and the Canon PowerShot SX720 HS? 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.
An illustration of the physical size and weight of the Canon G9 X Mark II and the Canon SX720 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.
The G9X Mark II can be obtained in two different colors (black, silver), while the SX720 is also available in two color-versions, but different ones (black, red).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon SX720 is notably larger (24 percent) than the Canon G9 X Mark II. Moreover, the SX720 is markedly heavier (31 percent) than the G9X Mark II. In this context, it is worth noting that neither the G9X Mark II nor the SX720 are weather-sealed.
The power pack in the G9X Mark II can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The SX720 was launched at a markedly lower price (by 28 percent) than the G9X Mark II, which puts it into a different market segment. 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.
The size of the sensor inside a digital camera is one of the key determinants 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon G9 X Mark II features an one-inch sensor and the Canon SX720 a 1/2.3-inch sensor. The sensor area in the SX720 is 76 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 5.6. The sensor in the G9X Mark II has a native 3:2 aspect ratio, while the one in the SX720 offers a 4:3 aspect.
In terms of chip-set technology, the G9X Mark II uses a more advanced image processing engine (DIGIC 7) than the SX720 (DIGIC 6), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a smaller sensor, the SX720 offers a slightly higher resolution of 20.2 megapixels, compared with 20 MP of the G9X Mark II. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.18μm versus 2.41μm for the G9X Mark II). Moreover, it should be noted that the G9X Mark II is a somewhat more recent model (by 10 months) than the SX720, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the SX720 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The Canon PowerShot G9 X Mark II has a native sensitivity range from ISO 125 to ISO 12800. The corresponding ISO settings for the Canon PowerShot SX720 HS are ISO 80 to ISO 3200 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. 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 range of features. The G9X Mark II and the SX720 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 Mark II and Canon SX720 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G9X Mark II has a touchscreen, while the SX720 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
The Canon G9 X Mark II has 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 G9X Mark II and the SX720 have zoom lenses built in. The G9X Mark II has a 28-84mm f/2.0-4.9 optic and the SX720 offers a 24-960mm f/3.3-6.9 (focal lengths in full frame equivalent terms). Hence, the SX720 provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the G9X Mark II. The G9X Mark II offers the faster maximum aperture.
Concerning the storage of imaging data, both the G9X Mark II and the SX720 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 G9 X Mark II and Canon PowerShot SX720 HS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The G9X Mark II is a recent model that features in the current product line-up of Canon. In contrast, the SX720 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the SX720 was succeeded by the Canon SX730. 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 how do things add up? Is the Canon G9 X Mark II better than the Canon SX720 or vice versa? The listing below highlights the relative strengths of the two models.
Advantages of the Canon PowerShot G9 X Mark II:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.

- Faster shutter: Has higher mechanical shutter speed (1/3200s vs 1/2000s) to freeze action.
- 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 affordable: Was introduced into a lower priced category (28 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in February 2016).
If the count of individual advantages (bullet points above) is taken as a guide, the G9X Mark II is the clear winner of the match-up (16 : 6 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 G9 X Mark II and the Canon SX720 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Superzoom Camera listings 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 says little about, for example, the shooting experience and imaging performance of the G9X Mark II and the SX720 in practical situations. 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 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 assessments were made in relation to similar cameras of the same technological generation. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
