Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX500 IS and the Canon EOS Rebel T100? 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 side-by-side display below illustrates the physical size and weight of the Canon SX500 and the Canon T100. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon T100 is considerably larger (81 percent) than the Canon SX500. In this context, it is worth noting that neither the SX500 nor the T100 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX500 has a lens built in, whereas the T100 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 T100 and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the SX500 gets 195 shots out of its Canon NB-6L battery, while the T100 can take 500 images on a single charge of its Canon LP-E10 power pack.

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.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The SX500 was launched at a lower price than the T100, 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon SX500 features a 1/2.3-inch sensor and the Canon T100 an APS-C sensor. The sensor area in the T100 is 1086 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.6. The sensor in the SX500 has a native 4:3 aspect ratio, while the one in the T100 offers a 3:2 aspect.

Technology-wise, the T100 uses a more advanced image processing engine (DIGIC 4+) than the SX500 (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.

With 17.9MP, the T100 offers a higher resolution than the SX500 (15.9MP), but the T100 nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 1.33μm for the SX500) due to its larger sensor. Moreover, the T100 is a much more recent model (by 5 years and 6 months) than the SX500, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the SX500 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon T100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T100 for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Canon SX500 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.

The Canon PowerShot SX500 IS has a native sensitivity range from ISO 80 to ISO 1600. The corresponding ISO settings for the Canon EOS Rebel T100 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800.

In terms of underlying technology, the SX500 is build around a CCD sensor, while the T100 uses a 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 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 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 also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the T100 provides a better video resolution than the SX500. It can shoot movie footage at 1080/30p, while the SX500 is limited to 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the T100 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the SX500 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon SX500 and Canon T100 along with similar information for a selection of comparators.

It is notable that the T100 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the SX500 does not provide wifi capability.

The T100 is a recent model that features in the current product line-up of Canon. In contrast, the SX500 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the SX500 was succeeded by the Canon SX510. Further information on the features and operation of the SX500 and T100 can be found, respectively, in the Canon SX500 Manual (free pdf) or the online Canon T100 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Canon SX500 and the Canon T100? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Canon PowerShot SX500 IS:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (461k vs 230k dots).
• Ready to shoot: Comes with a built-in lens, while the T100 requires a separate lens.
• More compact: Is smaller (104x70mm vs 129x102mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the T100).
• Sharper images: Has hand-shake reducing image stabilization built-in.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More heavily discounted: Has been available for much longer (launched in August 2012).

Advantages of the Canon EOS Rebel T100:

• More detail: Has more megapixels (17.9 vs 15.9MP), which boosts linear resolution by 8%.
• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Is equipped with a larger and more technologically advanced 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 4+ vs DIGIC 4).
• Better video: Provides higher definition movie capture (1080/30p vs 720/30p).
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/1600s) to freeze action.
• Faster burst: Shoots at higher frequency (3 vs 0.8 flaps/sec) to capture the decisive moment.
• More flexible: Makes it possible to change lenses and thus to use specialty optics.
• Longer lasting: Gets more shots (500 versus 195) out of a single battery charge.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More modern: Reflects 5 years and 6 months of technical progress since the SX500 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the T100 is the clear winner of the contest (17 : 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 SX500 and the Canon T100 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best DSLR 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 incomplete and does no justice, for example, to the way the SX500 or the T100 perform in practice. 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 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.

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. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
