Canon 100D vs SX720
The Canon EOS 100D (called Canon SL1 in some regions) and the Canon PowerShot SX720 HS are two digital cameras that were announced, respectively, in March 2013 and February 2016. The 100D is a DSLR, while the SX720 is a fixed lens compact. The cameras are based on an APS-C (100D) and a 1/2.3-inch (SX720) sensor. The 100D has a resolution of 17.9 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 100D 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 100D and the Canon SX720 is provided 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 size dimensions are rounded to the nearest millimeter.
The 100D 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 (34 percent) than the Canon 100D. In this context, it is worth noting that neither the 100D 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 100D 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 100D 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. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 SX720 was launched at a lower price than the 100D, 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon 100D 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 100D has a native 3:2 aspect ratio, while the one in the SX720 offers a 4:3 aspect.
Technology-wise, the SX720 uses a more advanced image processing engine (DIGIC 6) than the 100D (DIGIC 5), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a smaller sensor, the SX720 offers a higher resolution of 20.2 megapixels, compared with 17.9 MP of the 100D. This megapixels 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 4.31μm for the 100D). However, it should be noted that the SX720 is much more recent (by 2 years and 10 months) than the 100D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. 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 100D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 100D has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Canon PowerShot SX720 HS are ISO 80 to ISO 3200 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.
|Canon 7D II||APS-C||20.0||5472||3648||1080/60p||22.4||11.8||1082||70|

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 SX720 provides a faster frame rate than the 100D. It can shoot movie footage at 1080/60p, while the 100D is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the 100D 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 table below summarizes some of the other core capabilities of the Canon 100D and Canon SX720 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 100D has a touchscreen, while the SX720 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
Concerning the storage of imaging data, both the 100D 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 100D 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 100D has a hotshoe, while the SX720 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the 100D and the SX720 have been discontinued, but can regularly be found used on eBay. The 100D was replaced by the Canon 200D, while the SX720 was followed 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.
So what conclusions can be drawn? Which of the two cameras – the Canon 100D or the Canon SX720 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Canon EOS 100D:

If the count of relative strengths (bullet points above) is taken as a measure, the 100D emerges as the winner of the contest (15 : 12 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 100D 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 100D or the SX720. 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 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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
