Canon SL3 vs SX720
The Canon EOS Rebel SL3 (called Canon 250D in some regions) and the Canon PowerShot SX720 HS are two digital cameras that were announced, respectively, in April 2019 and February 2016. The SL3 is a DSLR, while the SX720 is a fixed lens compact. The cameras are based on an APS-C (SL3) and a 1/2.3-inch (SX720) sensor. The SL3 has a resolution of 24 megapixels, whereas the SX720 provides 20.2 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS Rebel SL3 and the Canon PowerShot SX720 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.
An illustration of the physical size and weight of the Canon SL3 and the Canon SX720 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
The SL3 can be obtained in two different colors (black, white), while the SX720 is also available in two color-versions, but different ones (black, red).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon SX720 is considerably smaller (38 percent) than the Canon SL3. In this context, it is worth noting that neither the SL3 nor the SX720 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX720 has a lens built in, whereas the SL3 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the SL3 and their specifications in the Canon EF Lens Catalog.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. 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 SX720 was launched at a lower price than the SL3, despite having a lens built in. 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.
The size of the sensor inside a digital camera is one of the key determinants 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 SL3 features an APS-C sensor and the Canon SX720 a 1/2.3-inch sensor. The sensor area in the SX720 is 92 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 5.6. The sensor in the SL3 has a native 3:2 aspect ratio, while the one in the SX720 offers a 4:3 aspect.
In terms of chip-set technology, the SL3 uses a more advanced image processing engine (DIGIC 8) than the SX720 (DIGIC 6), with benefits for noise reduction, color accuracy, and processing speed.
With 24MP, the SL3 offers a higher resolution than the SX720 (20.2MP), but the SL3 nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 1.18μm for the SX720) due to its larger sensor. Moreover, the SL3 is a much more recent model (by 3 years and 1 month) than the SX720, and its sensor will 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 SX720 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon SL3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SL3 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Canon SX720 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 SL3 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS Rebel SL3 has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. The corresponding ISO settings for the Canon PowerShot SX720 HS are ISO 80 to ISO 3200 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

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, but the SL3 provides a higher video resolution than the SX720. It can shoot video footage at 4K/25p, while the SX720 is limited to 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the SL3 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the SX720 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon SL3 and Canon SX720 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 SL3 has a touchscreen, while the SX720 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The SL3 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the SX720 does not have a selfie-screen.
The Canon SL3 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 SL3 and the SX720 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 Rebel SL3 and Canon PowerShot SX720 HS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SL3 has a hotshoe, while the SX720 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
The SL3 is a recent model that features in the current product line-up of Canon. In contrast, the SX720 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the SX720 was succeeded by the Canon SX730. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.

If the number of relative strengths (bullet points above) is taken as a guide, the SL3 is the clear winner of the match-up (22 : 9 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 SL3 and the Canon SX720 place the cameras among the top in their class? Find out in the latest Best DSLR 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 remains incomplete and does no justice, for example, to the way the SL3 or the SX720 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 where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
