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 SX730 was launched at a markedly lower price (by 43 percent) than the G7X, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon G7 X features an one-inch sensor and the Canon SX730 a 1/2.3-inch sensor. The sensor area in the SX730 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 G7X has a native 3:2 aspect ratio, while the one in the SX730 offers a 4:3 aspect.
Despite having a smaller sensor, the SX730 offers a slightly higher resolution of 20.2 megapixels, compared with 20 MP of the G7X. 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 G7X). However, it should be noted that the SX730 is much more recent (by 2 years and 6 months) than the G7X, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the SX730 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The Canon PowerShot G7 X has a native sensitivity range from ISO 125 to ISO 12800. The corresponding ISO settings for the Canon PowerShot SX730 HS are ISO 80 to ISO 3200 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-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 variety of features. The G7X and the SX730 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 adjacent table lists some of the other core features of the Canon G7 X and Canon SX730 along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G7X has a touchscreen, while the SX730 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
The Canon G7 X 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 G7X and the SX730 have zoom lenses built in. The G7X has a 24-100mm f/1.8-2.8 optic and the SX730 offers a 24-960mm f/3.3-6.9 (focal lengths in full frame equivalent terms). Hence, the G7X and SX730 provide the same view at the wide-angle end, but the SX730 has more tele-photo reach at the long end. The G7X offers the faster maximum aperture.
Concerning the storage of imaging data, both the G7X and the SX730 write their files to SDXC cards. The G7X supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the SX730 cannot take advantage of Ultra High Speed SD cards.
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 SX730 HS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the G7X and the SX730 have been discontinued, but can regularly be found used on eBay. The G7X was replaced by the Canon G7 X Mark II, while the SX730 was followed by the Canon SX730 HS. 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 conclusions can be drawn? Is the Canon G7 X better than the Canon SX730 or vice versa? The listing below highlights the relative strengths of the two models.
Advantages of the Canon PowerShot G7 X:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
- Richer colors: The pixel size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/3.3).
- More compact: Is smaller (103x60mm vs 110x64mm) and thus needs less room in the bag.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More heavily discounted: Has been available for much longer (launched in September 2014).
Arguments in favor of the Canon PowerShot SX730 HS:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Faster shutter: Has higher mechanical shutter speed (1/3200s vs 1/2000s) to freeze action.
- More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
- Longer lasting: Gets more shots (250 versus 210) out of a single battery charge.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- More affordable: Was introduced into a lower priced category (43 percent cheaper at launch).
- More modern: Reflects 2 years and 6 months of technical progress since the G7X launch.
If the number of relative strengths (bullet points above) is taken as a guide, the G7X is the clear winner of the match-up (12 : 7 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. 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 and the Canon SX730 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the G7X or the SX730 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 hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
