Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX520 HS 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

An illustration of the physical size and weight of the Canon SX520 and the Canon T100 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 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 notably larger (34 percent) than the Canon SX520. In this context, it is worth noting that neither the SX520 nor the T100 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX520 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 SX520 gets 210 shots out of its Canon NB-6LH battery, while the T100 can take 500 images on a single charge of its Canon LP-E10 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon SX520 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 SX520 has a native 4:3 aspect ratio, while the one in the T100 offers a 3:2 aspect.

With 17.9MP, the T100 offers a higher resolution than the SX520 (15.9MP), but the T100 nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 1.33μm for the SX520) due to its larger sensor. Moreover, the T100 is a much more recent model (by 3 years and 7 months) than the SX520, 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 SX520 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 SX520 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 SX520 HS has a native sensitivity range from ISO 100 to ISO 3200. 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 SX520 is build around a BSI-CMOS 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the T100 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the SX520 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon SX520 and Canon T100 along with similar information for a selection of comparators.

Concerning the storage of imaging data, both the SX520 and the T100 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 SX520 HS and Canon EOS Rebel T100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

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 SX520 does not provide wifi capability.

The T100 is a recent model that features in the current product line-up of Canon. In contrast, the SX520 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the SX520 was succeeded by the Canon SX530. Further information on the features and operation of the SX520 and T100 can be found, respectively, in the Canon SX520 Manual (free pdf) or the online Canon T100 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Canon SX520 or the Canon T100 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Canon PowerShot SX520 HS:

• 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 (120x82mm vs 129x102mm) and thus needs less room in the bag.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• More heavily discounted: Has been available for much longer (launched in July 2014).

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.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (3 vs 1.6 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 210) 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 3 years and 7 months of technical progress since the SX520 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the T100 is the clear winner of the contest (15 : 7 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 SX520 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 says little about, for example, the shooting experience and imaging performance of the SX520 and the T100 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 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 assessments were made in relation to similar cameras of the same technological generation. 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, please note that some of the review sites have changed their methodology and reporting over time.
