Canon 20D versus Canon 10D
The Canon EOS 20D and the Canon EOS 10D are two enthusiast cameras that were revealed to the public, respectively, in August 2004 and February 2003. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 20D has a resolution of 8.2 megapixel, whereas the 10D provides 6.3 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.
Body comparison: Canon 20D vs Canon 10D
An illustration of the physical size and weight of the Canon 20D and the Canon 10D is provided in the side-by-side display below. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the 20D – represents the basis or 100 percent across all the size and weight measures).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 10D is notably larger (5 percent) than the Canon 20D. Moreover, the 10D is markedly heavier (10 percent) than the 20D. In this context, it is worth noting that neither the 20D nor the 10D 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 find an overview of suitable optics 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 want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 20D was launched at a somewhat lower price (by 25 percent) than the 10D, which makes it more attractive for photographers on a tight budget. 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: Canon 20D vs Canon 10D
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.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the 10D is 1 percent bigger. 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.
Despite having a slightly smaller sensor, the Canon 20D offers a higher resolution of 8.2 megapixel, compared with 6.3 MP of the Canon 10D. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 6.42μm versus 7.38μm for the 10D). However, it should be noted that the 20D is a somewhat more recent model (by 1 year and 5 months) than the 10D, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.
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"). Of the two cameras under review, the 20D has a notably higher overall DXO score than the 10D (overall score 5 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.8 bits higher color depth, 0.1 EV in additional dynamic range, and 0.3 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Feature comparison: Canon 20D vs Canon 10D
Beyond body and sensor, cameras can and do differ across a range of features. The 20D and the 10D 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 10D along with similar information for a selection of comparators. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the 20D and the 10D have been discontinued, but can regularly be found used on eBay. The 10D was replaced by the Canon 20D, while the 20D was followed by the Canon 30D.
Review summary: Canon 20D vs Canon 10D
So what is the bottom line? Which of the two cameras – the Canon 20D or the Canon 10D – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Canon EOS 20D:
- More detail: Offers more megapixels (8.2 vs 6.3MP) with a 14% higher linear resolution.
- Better image quality: Scores markedly higher (5 points) in the DXO overall assessment.
- Better low-light sensitivity: Requires less light for good images (0.3 stops ISO advantage).
- 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 500) on a single battery charge.
- More affordable: Was introduced into a lower priced segment (25 percent cheaper at launch).
- More modern: Is somewhat more recent (announced 1 year and 5 months after the 10D).
Arguments in favor of the Canon EOS 10D:
- More heavily discounted: Has been on the market for longer (launched in February 2003).
If the count of individual advantages (bullet points above) is taken as a guide, the 20D is the clear winner of the match-up (8 : 1 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 partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 20D or the 10D. 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. This is why expert reviews are important. The table below summarizes the assessments of some of the best known camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The review scores listed above should be treated with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
