Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX20 IS and the Canon PowerShot SX50 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.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon SX20 and the Canon SX50. 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 width, height and depth 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 SX50 is somewhat smaller (1 percent) than the Canon SX20. Moreover, the SX50 is slightly lighter (1 percent) than the SX20. In this context, it is worth noting that neither the SX20 nor the SX50 are weather-sealed.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The SX20 was somewhat cheaper (by 7 percent) than the SX50 at launch, but both cameras fall into the same price category. 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 associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature a 1/2.3-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 5.6. Within the spectrum of camera sensors, this places the review cameras among the smaller-sensor digicams that favor affordability and compact design. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Technology-wise, the SX50 uses a more advanced image processing engine (DIGIC 5) than the SX20 (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 12 megapixels. This similarity in sensor specs implies that both the SX20 and the SX50 have the same pixel density, as well as the same pixel size. It should, however, be noted that the SX50 is much more recent (by 3 years) than the SX20, and its sensor will have benefitted from technological advances during this time. Coming back to sensor resolution, it should be mentioned that the SX20 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The Canon PowerShot SX20 IS has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Canon PowerShot SX50 HS are ISO 80 to ISO 6400 (no boost).

In terms of underlying technology, the SX20 is build around a CCD sensor, while the SX50 uses a BSI-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, but the SX50 provides a better video resolution than the SX20. It can shoot movie footage at 1080/24p, while the SX20 is limited to 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The SX20 and the SX50 are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 202k dots. The following table reports on some other key feature differences and similarities of the Canon SX20, the Canon SX50, and comparable cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

Both the SX20 and the SX50 have zoom lenses built in. The SX20 has a 28-560mm f/2.8-5.7 optic and the SX50 offers a 24-1200mm f/3.4-6.5 (focal lengths in full frame equivalent terms). Hence, the SX50 provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the SX20. The SX20 offers the faster maximum aperture.

The SX20 writes its imaging data to SDHC cards, while the SX50 uses 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 SX20 IS and Canon PowerShot SX50 HS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Further information on the features and operation of the SX20 and SX50 can be found, respectively, in the Canon SX20 Manual (free pdf) or the online Canon SX50 Manual.

Review summary

So what is the bottom line? Is the Canon SX20 better than the Canon SX50 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Canon PowerShot SX20 IS:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Faster shutter: Has higher mechanical shutter speed (1/3200s vs 1/2000s) to freeze action.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.8 vs f/3.4).
• More heavily discounted: Has been available for much longer (launched in August 2009).

Reasons to prefer the Canon PowerShot SX50 HS:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better jpgs: Has a more modern image processing engine (DIGIC 5 vs DIGIC 4).
• Better video: Provides higher definition movie capture (1080/24p vs 720/30p).
• Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (461k vs 230k dots).
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (2.2 vs 0.7 flaps/sec) to capture the decisive moment.
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• More modern: Reflects 3 years of technical progress since the SX20 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the SX50 is the clear winner of the contest (10 : 4 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 SX20 and the Canon SX50 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the SX20 or the SX50 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.

Expert reviews

This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

Care should be taken when interpreting the review scores above, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
