Canon SX730 versus Canon G9 X

The Canon PowerShot SX730 HS and the Canon PowerShot G9 X are two digital cameras that were revealed to the public, respectively, in April 2017 and October 2015. Both the SX730 and the G9X are fixed lens compact cameras that are based on a 1/2.3-inch (SX730) and an one-inch (G9X) sensor. The SX730 has a resolution of 20.2 megapixel, whereas the G9X provides 20 MP. 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.

Any camera purchase 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 somewhat lower price (by 25 percent) than the G9X, which makes it more attractive for photographers on a tight budget. 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.

 

Sensor comparison: Canon SX730 vs Canon G9 X

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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.

Of the two cameras under consideration, the Canon SX730 features a 1/2.3-inch sensor and the Canon G9 X an one-inch sensor. The sensor area in the G9X is 314 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 2.7. The sensor in the SX730 has a native 4:3 aspect ratio, while the one in the G9X offers a 3:2 aspect.

Canon SX730 and Canon G9 X sensor measures

Despite having a smaller sensor, the Canon SX730 offers a higher resolution of 20.2 megapixel, compared with 20 MP of the Canon G9 X. This megapixel 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). However, it should be noted that the SX730 is a somewhat more recent model (by 1 year and 5 months) than the G9X, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage. 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.

SX730 versus G9X MP

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

 

Feature comparison: Canon SX730 vs Canon G9 X

Beyond body and sensor, cameras can and do differ across a range of features. The SX730 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 adjacent table lists some of the other core features of the Canon SX730 and Canon G9 X 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 G9X has a touchscreen, while the SX730 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point or for making menu selections.

Both the SX730 and the G9X have zoom lenses build in. The SX730 has a 24-960mm f/3.3-6.9 optic and the G9X offers a 28-84mm f/2.0-4.9 (focal lengths in full frame equivalent terms). Hence, the SX730 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 G9X offers the faster maximum aperture.

Both the SX730 and the G9X have been discontinued, but can regularly be found used on eBay. The G9X was replaced by the Canon G9 X Mark II, while the SX730 was followed by the Canon SX730 HS.

Review summary: Canon SX730 vs Canon G9 X

So what is the bottom line? Is the Canon SX730 better than the Canon G9 X or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Canon PowerShot SX730 HS:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (3200/sec vs 2000/sec) 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.
  • Longer lasting: Can take more shots (250 versus 220) on a single battery charge.
  • More affordable: Was introduced into a lower priced segment (25 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 1 year and 5 months after the G9X).


Advantages of the Canon PowerShot G9 X:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Better light gathering: Has a lens with a wider maximum aperture (f/2.0 vs f/3.3).
  • More compact: Is smaller (98x58mm vs 110x64mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 91g or 30 percent) and is thus easier to take along.
  • More heavily discounted: Has been on the market for longer (launched in October 2015).

If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (8 points each). 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.

SX730 08:08 G9X

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the SX730 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 hands-on reviews by experts 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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
