Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS RP 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

The physical size and weight of the Canon RP and the Canon SX730 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter.

The SX730 can be obtained in two different colors (black, silver), while the RP 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 considerably smaller (38 percent) than the Canon RP. In this context, it is worth noting that neither the RP nor the SX730 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX730 has a lens built in, whereas the RP is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

The price is, of course, an important factor in any camera decision. 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 SX730 was launched at a lower price than the RP, despite having a lens built in. 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 size of the imaging sensor is a crucial determinant 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. 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.

Of the two cameras under consideration, the Canon RP features a full frame sensor and the Canon SX730 a 1/2.3-inch sensor. The sensor area in the SX730 is 97 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 5.6. The sensor in the RP has a native 3:2 aspect ratio, while the one in the SX730 offers a 4:3 aspect.

In terms of chip-set technology, the RP uses a more advanced image processing engine (DIGIC 8) than the SX730 (DIGIC 6), with benefits for noise reduction, color accuracy, and processing speed.

With 26MP, the RP offers a higher resolution than the SX730 (20.2MP), but the RP nevertheless has larger individual pixels (pixel pitch of 5.76μm versus 1.18μm for the SX730) due to its larger sensor. Moreover, the RP is a somewhat more recent model (by 1 year and 10 months) than the SX730, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. 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 resolution advantage of the Canon RP implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RP for good quality output (200 dots per inch) amounts to 31.2 x 20.8 inches or 79.2 x 52.8 cm, for very good quality (250 dpi) 25 x 16.6 inches or 63.4 x 42.3 cm, and for excellent quality (300 dpi) 20.8 x 13.9 inches or 52.8 x 35.2 cm. The corresponding values for the Canon SX730 are 25.9 x 19.4 inches or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inches or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inches or 43.9 x 32.9 cm for excellent quality prints.

The RP has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS RP has a native sensitivity range from ISO 100 to ISO 40000, which can be extended to ISO 50-102400. The corresponding ISO settings for the Canon PowerShot SX730 HS are ISO 80 to ISO 3200 (no boost).

In terms of underlying technology, the RP is build around a CMOS 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.

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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Note: DXO values in italics represent estimates based on sensor size and age.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the RP provides a higher video resolution than the SX730. It can shoot video footage at 4K/30p, while the SX730 is limited to 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the RP 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 following table reports on some other key feature differences and similarities of the Canon RP, the Canon SX730, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The RP has a touchscreen, while the SX730 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Canon RP 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.

Concerning the storage of imaging data, both the RP and the SX730 write their files to SDXC cards. The RP supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the SX730 cannot take advantage of Ultra High Speed SD 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 EOS RP and Canon PowerShot SX730 HS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RP has a hotshoe, while the SX730 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

The RP is a recent model that features in the current product line-up of Canon. In contrast, the SX730 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the SX730 was succeeded by the Canon SX730 HS. Further information on the features and operation of the RP and SX730 can be found, respectively, in the Canon RP Manual (free pdf) or the online Canon SX730 Manual.

Review summary

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

Arguments in favor of the Canon EOS RP:

• More detail: Offers more megapixels (26 vs 20.2MP) with a 16% higher linear resolution.
• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Features a larger and more technologically advanced imaging sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Better jpgs: Has a more modern image processing engine (DIGIC 8 vs DIGIC 6).
• Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Better sound control: Has a headphone port that enables audio monitoring while recording.
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/3200s) to freeze action.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Faster buffer clearing: Supports Ultra High Speed (UHS-II) SDXC cards.
• More modern: Is somewhat more recent (announced 1 year and 10 months after the SX730).

Reasons to prefer the Canon PowerShot SX730 HS:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Faster burst: Shoots at higher frequency (5.9 vs 5 flaps/sec) to capture the decisive moment.
• Ready to shoot: Has an integrated lens, whereas the RP necessitates an extra lens.
• More compact: Is smaller (110x64mm vs 133x85mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the RP).
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More heavily discounted: Has been on the market for longer (launched in April 2017).

If the count of individual advantages (bullet points above) is taken as a guide, the RP is the clear winner of the match-up (21 : 10 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 RP and the Canon SX730 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Superzoom Camera listings 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 RP and the SX730 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.

Expert reviews

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

Care should be taken when interpreting the review scores above, 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
