Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX430 IS and the Canon PowerShot SX730 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.

Body comparison

An illustration of the physical size and weight of the Canon SX430 and the Canon SX730 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

The SX730 can be obtained in two different colors (black, silver), while the SX430 is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon SX730 is somewhat smaller (2 percent) than the Canon SX430. Moreover, the SX730 is markedly lighter (7 percent) than the SX430. In this context, it is worth noting that neither the SX430 nor the SX730 are weather-sealed.

Concerning battery life, the SX430 gets 195 shots out of its Canon NB-11LH battery, while the SX730 can take 250 images on a single charge of its Canon NB-13L power pack. The power pack in the SX730 can be charged via the USB port, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The SX430 was launched at a somewhat lower price (by 25 percent) than the SX730, which makes it more attractive for photographers on a tight budget. 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. 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. 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 tend to be associated with larger, more expensive camera bodies 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 SX430 (DIGIC 4+), with benefits for noise reduction, color accuracy, and processing speed.

While the two cameras under review share the same sensor size, the SX730 offers a slightly higher resolution of 20.2 megapixels, compared with 19.9 MP of the SX430. This megapixels advantage translates into a 0.59999999999999 percent gain in linear resolution. On the other hand, these sensor specs imply that the SX730 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.18μm versus 1.19μm for the SX430). However, it should be noted that the SX730 is a somewhat more recent model (by 2 months) than the SX430, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size. 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 SX430 IS has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon PowerShot SX730 HS are ISO 80 to ISO 3200 (no boost).

In terms of underlying technology, the SX430 is build around a CCD sensor, while the SX730 uses a BSI-CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the SX730 provides a better video resolution than the SX430. It can shoot movie footage at 1080/60p, while the SX430 is limited to 720/25p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The SX430 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 SX430 and Canon SX730 along with similar information for a selection of comparators.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

Both the SX430 and the SX730 have zoom lenses built in. The SX430 has a 24-1080mm f/3.5-6.6 optic and the SX730 offers a 24-960mm f/3.3-6.9 (focal lengths in full frame equivalent terms). Hence, the SX430 and SX730 provide the same view at the wide-angle end, but the SX730 has less tele-photo reach at the long end. The SX730 offers the faster maximum aperture.

Concerning the storage of imaging data, both the SX430 and the SX730 write their files to SDXC cards.

Connectivity comparison

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 SX430 IS and Canon PowerShot SX730 HS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the SX430 and the SX730 have been discontinued, but can regularly be found used on ebay. The SX730 was replaced by the Canon SX730 HS, while the SX430 does not have a direct successor. Further information on the features and operation of the SX430 and SX730 can be found, respectively, in the Canon SX430 Manual (free pdf) or the online Canon SX730 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon SX430 and the Canon SX730? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Canon PowerShot SX430 IS:

• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/3200s) to freeze action.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• More affordable: Was introduced into a lower priced segment (25 percent cheaper at launch).

Advantages of the Canon PowerShot SX730 HS:

• Better jpgs: Has a more modern image processing engine (DIGIC 6 vs DIGIC 4+).
• Better video: Provides higher definition movie capture (1080/60p vs 720/25p).
• More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
• 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 burst: Shoots at higher frequency (5.9 vs 0.5 flaps/sec) to capture the decisive moment.
• Better light gathering: Has a lens with a wider maximum aperture (f/3.3 vs f/3.5).
• Longer lasting: Gets more shots (250 versus 195) out of a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.

If the count of individual advantages (bullet points above) is taken as a guide, the SX730 is the clear winner of the contest (10 : 3 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 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.

How about other alternatives? Do the specifications of the Canon SX430 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 technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the SX430 and the SX730 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.

Expert reviews

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
