Canon 20D vs XS
The Canon EOS 20D and the Canon EOS Rebel XS (labelled Canon 1000D in some countries) are two digital cameras that were officially introduced, respectively, in August 2004 and June 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 20D has a resolution of 8.2 megapixels, whereas the XS provides 10.1 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 20D 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.
An illustration of the physical size and weight of the Canon 20D and the Canon XS is provided 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 smaller (19 percent) than the Canon 20D. Moreover, the XS is substantially lighter (35 percent) than the 20D. In this context, it is worth noting that neither the 20D nor the XS are weather-sealed.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Canon EF Lens Catalog.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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 XS was launched at a markedly lower price (by 70 percent) than the 20D, which puts it into a different market segment. 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.
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. 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.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the XS is 3 percent smaller. They nevertheless have the same format factor of 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, the XS uses a more advanced image processing engine (DIGIC 3) than the 20D (DIGIC 2), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a slightly smaller sensor, the XS offers a higher resolution of 10.1 megapixels, compared with 8.2 MP of the 20D. 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 5.71μm versus 6.42μm for the 20D). However, it should be noted that the XS is much more recent (by 3 years and 9 months) than the 20D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Canon XS implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the XS for good quality output (200 dots per inch) amounts to 19.4 x 13 inch or 49.4 x 32.9 cm, for very good quality (250 dpi) 15.6 x 10.4 inch or 39.5 x 26.3 cm, and for excellent quality (300 dpi) 13 x 8.6 inch or 32.9 x 21.9 cm. The corresponding values for the Canon 20D are 17.5 x 11.7 inch or 44.5 x 29.7 cm for good quality, 14 x 9.3 inch or 35.6 x 23.7 cm for very good quality, and 11.7 x 7.8 inch or 29.7 x 19.8 cm for excellent quality prints.
The Canon EOS 20D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. 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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Apart from body and sensor, cameras can and do differ across a range of features. The 20D and the XS are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinders of both cameras offer the same field of view (95%), but the viewfinder of the 20D has a higher magnification than the one of the XS (0.56x vs 0.51x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 20D and Canon XS in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 20D, but is missing on the XS is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
The 20D writes its imaging data to Compact Flash cards, while the XS uses SDHC cards.
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.

Studio photographers will appreciate that the Canon 20D (unlike the XS) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 20D and the XS have been discontinued, but can regularly be found used on eBay. The 20D was replaced by the Canon 30D, while the XS was followed by the Canon T3. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what conclusions can be drawn? Which of the two cameras – the Canon 20D or the Canon XS – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Canon EOS 20D:
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.56x vs 0.51x).
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (700 versus 500) on a single battery charge.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More heavily discounted: Has been available for much longer (launched in August 2004).
Advantages of the Canon EOS Rebel XS:
- More detail: Has more megapixels (10.1 vs 8.2MP), which boosts linear resolution by 11%.
- Better jpgs: Has a more modern image processing engine (DIGIC 3 vs DIGIC 2).
- Larger screen: Has a bigger rear LCD (2.5" vs 1.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (230k vs 118k dots).
- More compact: Is smaller (126x98mm vs 144x106mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 268g or 35 percent) and is thus easier to take along.
- Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
- More affordable: Was introduced into a lower priced category (70 percent cheaper at launch).
- More modern: Reflects 3 years and 9 months of technical progress since the 20D launch.
If the count of relative strengths (bullet points above) is taken as a measure, the XS emerges as the winner of the match-up (9 : 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 20D and the Canon XS place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 20D or the XS. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price 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.
