Canon 20D vs XT
The Canon EOS 20D and the Canon EOS Rebel XT (labelled Canon 350D in some countries) are two digital cameras that were announced, respectively, in August 2004 and February 2005. 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 XT provides 8 MP. Read on to find out how these two cameras compare with respect to their body size, their sensors, their features, their input-output connections, and their reception by expert reviewers.

Body comparison: Canon 20D vs XT
The physical size and weight of the Canon 20D and the Canon XT are illustrated 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 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 XT is notably smaller (22 percent) than the Canon 20D. Moreover, the XT is markedly lighter (30 percent) than the 20D. In this context, it is worth noting that neither the 20D nor the XT 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 table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The XT was launched at a markedly lower price (by 40 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison: Canon 20D vs XT
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. 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 more expensive and lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the XT 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.
With 8.2MP, the 20D offers a slightly higher resolution than the XT (8MP), but the 20D nevertheless has marginally larger individual pixels (pixel pitch of 6.42μm versus 6.41μm for the XT) due to its larger sensor. However, the XT is a somewhat more recent model (by 5 months) than the 20D, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
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 XT are ISO 100 to ISO 1600 (no boost).
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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Feature comparison: Canon 20D vs XT
Apart from body and sensor, cameras can and do differ across a variety of features. The 20D and the XT 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 adjacent table lists some of the other core features of the Canon 20D and Canon XT along with similar information for a selection of comparators.

One feature that is present on the 20D, but is missing on the XT 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.
Concerning the storage of imaging data, both the 20D and the XT write their files to Compact Flash cards.
Connectivity comparison: Canon 20D vs XT
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 EOS 20D and Canon EOS Rebel XT and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 20D (unlike the XT) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 20D and the XT have been discontinued, but can regularly be found used on eBay. The 20D was replaced by the Canon 30D, while the XT was followed by the Canon Xti.
Review summary: Canon 20D vs XT
So what conclusions can be drawn? Is the Canon 20D better than the Canon XT or vice versa? The listing below highlights the relative strengths of the two models.
Advantages of the Canon EOS 20D:
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) 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 400) 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 on the market for longer (launched in August 2004).
Arguments in favor of the Canon EOS Rebel XT:
- More compact: Is smaller (127x94mm vs 144x106mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 230g or 30 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 (40 percent cheaper at launch).
- More modern: Was introduced somewhat (5 months) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the 20D comes out slightly ahead of the XT (6 : 5 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.
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 20D or the XT handle or 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.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
