Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX20 IS and the Canon EOS Rebel XS? 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 physical size and weight of the Canon SX20 and the Canon XS are illustrated 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon XS is notably larger (14 percent) than the Canon SX20. In this context, it is worth noting that neither the SX20 nor the XS are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX20 has a lens built in, whereas the XS 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 XS and their specifications in the Canon EF Lens Catalog.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Convert to Imperial

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. The SX20 was launched at a lower price than the XS, 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. 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. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 SX20 features a 1/2.3-inch sensor and the Canon XS an APS-C sensor. The sensor area in the XS is 1075 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 SX20 has a native 4:3 aspect ratio, while the one in the XS offers a 3:2 aspect.

In terms of chip-set technology, the SX20 uses a more advanced image processing engine (DIGIC 4) than the XS (DIGIC 3), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a smaller sensor, the Canon SX20 offers a higher resolution of 12 megapixels, compared with 10.1 MP of the Canon XS. 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 1.53μm versus 5.71μm for the XS). However, it should be noted that the SX20 is a somewhat more recent model (by 1 year and 2 months) than the XS, 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 SX20 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon SX20 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX20 for good quality output (200 dots per inch) amounts to 20 x 15 inches or 50.8 x 38.1 cm, for very good quality (250 dpi) 16 x 12 inches or 40.6 x 30.5 cm, and for excellent quality (300 dpi) 13.3 x 10 inches or 33.9 x 25.4 cm. The corresponding values for the Canon XS are 19.4 x 13 inches or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inches or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inches or 32.9 x 21.9 cm for excellent quality prints.

The Canon PowerShot SX20 IS has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Canon EOS Rebel XS are ISO 100 to ISO 800, with the possibility to increase the ISO range to 100-1600.

In terms of underlying technology, the SX20 is build around a CCD sensor, while the XS 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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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.

Many modern cameras cannot only take still pictures, but also record videos. The SX20 indeed provides movie recording capabilities, while the XS does not. The highest resolution format that the SX20 can use is 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the SX20 has an electronic viewfinder (202k dots), while the XS has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The table below summarizes some of the other core capabilities of the Canon SX20 and Canon XS in connection with corresponding information for a sample of similar cameras.

Both the SX20 and the XS have been discontinued, but can regularly be found used on ebay. The XS was replaced by the Canon T3, while the SX20 was followed by the Canon SX30. Further information on the features and operation of the SX20 and XS can be found, respectively, in the Canon SX20 Manual (free pdf) or the online Canon XS Manual.

Review summary

So how do things add up? Is the Canon SX20 better than the Canon XS or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon PowerShot SX20 IS:

• More detail: Offers more megapixels (12 vs 10.1MP) with a 7% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better jpgs: Has a more modern image processing engine (DIGIC 4 vs DIGIC 3).
• Broader imaging potential: Can record not only still images but also 720/30p movies.
• More framing info: Has an electronic viewfinder that displays shooting data.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Ready to shoot: Comes with a built-in lens, while the XS requires a separate lens.
• More compact: Is smaller (123x88mm vs 126x98mm) and thus needs less room in the bag.
• 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 modern: Is somewhat more recent (announced 1 year and 2 months after the XS).

Advantages of the Canon EOS Rebel XS:

• 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.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/3200s) to freeze action.
• Faster burst: Shoots at higher frequency (3 vs 0.7 flaps/sec) to capture the decisive moment.
• More flexible: Makes it possible to change lenses and thus to use specialty optics.
• More heavily discounted: Has been on the market for longer (launched in June 2008).

If the number of relative strengths (bullet points above) is taken as a guide, the SX20 comes out slightly ahead of the XS (11 : 10 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 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 SX20 and the Canon XS 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the SX20 or the XS 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 expert reviews 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.

Care should be taken when interpreting the review scores above, 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
