Any camera decision will obviously take relative prices into account. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The SX520 was launched at a somewhat lower price (by 11 percent) than the S120, which makes it more attractive for photographers on a tight budget. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon S120 features a 1/1.7-inch sensor and the Canon SX520 a 1/2.3-inch sensor. The sensor area in the SX520 is 35 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.5 and 5.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Despite having a smaller sensor, the SX520 offers a higher resolution of 15.9 megapixels, compared with 12 MP of the S120. 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 1.33μm versus 1.89μm for the S120). However, it should be noted that the SX520 is a somewhat more recent model (by 11 months) than the S120, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage. 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 SX520 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX520 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 cm. The corresponding values for the Canon S120 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The Canon PowerShot S120 has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Canon PowerShot SX520 HS are ISO 100 to ISO 3200 (no boost).

Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensors. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

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, but the S120 provides a higher frame rate than the SX520. It can shoot video footage at 1080/60p, while the SX520 is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The S120 and the SX520 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. The table below summarizes some of the other core capabilities of the Canon S120 and Canon SX520 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 S120 has a touchscreen, while the SX520 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Canon S120 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.

Both the S120 and the SX520 have zoom lenses built in. The S120 has a 24-120mm f/1.8-5.7 optic and the SX520 offers a 24-1008mm f/3.4-6 (focal lengths in full frame equivalent terms). Hence, the S120 and SX520 provide the same view at the wide-angle end, but the SX520 has more tele-photo reach at the long end. The S120 offers the faster maximum aperture.

Concerning the storage of imaging data, both the S120 and the SX520 write their files to SDXC cards. The S120 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the SX520 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 PowerShot S120 and Canon PowerShot SX520 HS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the S120 offers wifi support, while the SX520 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the S120 and the SX520 have been discontinued, but can regularly be found used on ebay. The SX520 was replaced by the Canon SX530, while the S120 does not have a direct successor. Further information on the features and operation of the S120 and SX520 can be found, respectively, in the Canon S120 Manual (free pdf) or the online Canon SX520 Manual.

Review summary

So how do things add up? Is the Canon S120 better than the Canon SX520 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Canon PowerShot S120:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
• More detailed LCD: Has a higher resolution rear screen (922k vs 461k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster burst: Shoots at higher frequency (12.1 vs 1.6 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/3.4).
• More compact: Is smaller (100x59mm vs 120x82mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 224g or 51 percent) and hence easier to carry around.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More heavily discounted: Has been on the market for longer (launched in August 2013).

Advantages of the Canon PowerShot SX520 HS:

• More detail: Has more megapixels (15.9 vs 12MP), which boosts linear resolution by 15%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• More affordable: Was released into a lower priced segment (11 percent cheaper at launch).
• More modern: Was introduced somewhat (11 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the S120 is the clear winner of the match-up (16 : 5 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 S120 and the Canon SX520 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom 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 incomplete and does no justice, for example, to the way the S120 or the SX520 perform in practice. 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 expert reviews are important. 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
