Comparison SX620 or SX730 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon SX730 is notably larger (27 percent) than the Canon SX620. Moreover, the SX730 is substantially heavier (65 percent) than the SX620. In this context, it is worth noting that neither the SX620 nor the SX730 are weather-sealed.

The power pack in the SX730 can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The SX620 was launched at a markedly lower price (by 30 percent) than the SX730, 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.

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 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. 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.

Both cameras under consideration feature a 1/2.3-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 5.6. Within the spectrum of camera sensors, this places the review cameras among the smaller-sensor digicams that favor affordability and compact design. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Technology-wise, the SX730 uses a more advanced image processing engine (DIGIC 6) than the SX620 (DIGIC 4+), with benefits for noise reduction, color accuracy, and processing speed.

Canon SX620 and Canon SX730 sensor measures

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 20.2 megapixels. This similarity in sensor specs implies that both the SX620 and the SX730 have the same pixel density, as well as the same pixel size. It should, however, be noted that the SX730 is a somewhat more recent model (by 10 months) than the SX620, and its sensor might have benefitted from technological advances during this time. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The Canon PowerShot SX620 HS has a native sensitivity range from ISO 80 to ISO 3200. The Canon PowerShot SX730 HS offers exactly the same ISO settings.

SX620 versus SX730 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras.

The SX730 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the SX620 does not have a selfie-screen.

Both the SX620 and the SX730 have zoom lenses built in. The SX620 has a 25-625mm f/3.2-6.6 optic and the SX730 offers a 24-960mm f/3.3-6.9 (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 SX620. The SX620 offers the faster maximum aperture.

Concerning the storage of imaging data, both the SX620 and the SX730 write their files to SDXC cards.

Review summary

So how do things add up? Is the Canon SX620 better than the Canon SX730 or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Reasons to prefer the Canon PowerShot SX620 HS:

  • Better light gathering: Has a lens with a wider maximum aperture (f/3.2 vs f/3.3).
  • More compact: Is smaller (97x57mm vs 110x64mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 118g or 39 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (295 versus 250) on a single battery charge.
  • More affordable: Was introduced into a lower priced category (30 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in May 2016).


Arguments in favor of the Canon PowerShot SX730 HS:

  • Better jpgs: Has a more modern image processing engine (DIGIC 6 vs DIGIC 4+).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • 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.
  • Faster shutter: Has higher mechanical shutter speed (1/3200s vs 1/2000s) to freeze action.
  • Faster burst: Shoots at higher frequency (5.9 vs 2.5 flaps/sec) to capture the decisive moment.
  • 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.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More modern: Was introduced somewhat (10 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the SX730 is the clear winner of the contest (11 : 6 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 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.

SX620 06:11 SX730

How about other alternatives? Do the specifications of the Canon SX620 and the Canon SX730 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the SX620 and the SX730 in practical situations. 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.

Expert reviews

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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.
