Canon SX730 versus Canon G5 X

The Canon PowerShot SX730 HS and the Canon PowerShot G5 X are two digital cameras that were announced, respectively, in April 2017 and October 2015. Both the SX730 and the G5X are fixed lens compact cameras that are based on a 1/2.3-inch (SX730) and an one-inch sensor. The SX730 has a resolution of 20.2 megapixel, whereas the G5X provides 20 MP.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon SX730 and the Canon G5 X. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the SX730 – represents the basis or 100 percent across all the size and weight measures).

The listed 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 50 percent) than the G5X, which puts it into a different market segment. 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

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. 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 are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon SX730 features a 1/2.3-inch sensor and the Canon G5 X an one-inch sensor. The sensor area in the G5X 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 G5X offers a 3:2 aspect.

Sensor size

Despite having a smaller sensor, the Canon SX730 offers a higher resolution of 20.2 megapixel, compared with 20 MP of the Canon G5 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 G5X). However, it should be noted that the SX730 is a somewhat more recent model (by 1 year and 5 months) than the G5X, 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.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/60p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G5X has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the SX730 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon SX730 and Canon G5 X in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the SX730 and the G5X have zoom lenses build in. The SX730 has a 24-960mm f/3.3-6.9 optic and the G5X offers a 24-100mm f/1.8-2.8 (focal lengths in full frame equivalent terms). Hence, the SX730 and G5X provide the same view at the wide-angle end, but the G5X has less tele-photo reach at the long end. The G5X offers the faster maximum aperture.

Both the SX730 and the G5X are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The SX730 replaced the earlier Canon SX720 HS, while the G5X does not have a direct predecessor.

Summary

So what is the bottom line? Is there a clear favorite between the Canon SX730 and the Canon SX730? The listing below highlights the relative strengths of the two models.


Reasons to prefer 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 (3200/sec vs 2000/sec) to freeze action.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • More compact: Is smaller (110x64mm vs 112x76mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 53g or 15 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (250 versus 210) on a single battery charge.
  • More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 1 year and 5 months after the G5X).

Arguments in favor of the Canon PowerShot G5 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.
  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • 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/1.8 vs f/3.3).
  • More heavily discounted: Has been on the market for longer (launched in October 2015).

If the number of relative strengths (bullet points above) is taken as a guide, 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.

SX730 08:08 G5X

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the SX730 and the G5X in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted 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 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.
