Canon 10D versus Canon 40D
The Canon EOS 10D and the Canon EOS 40D are two enthusiast cameras that were revealed to the public, respectively, in February 2003 and August 2007. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 10D has a resolution of 6.3 megapixel, whereas the 40D provides 10.1 MP.
An illustration of the physical size and weight of the Canon 10D and the Canon 40D 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 10D – 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 40D is somewhat smaller (2 percent) than the Canon 10D. Moreover, the 40D is slightly lighter (3 percent) than the 10D. In this context, it is worth noting that neither the 10D nor the 40D 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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 40D was launched at a markedly lower price (by 35 percent) than the 10D, which puts it into a different market segment. 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 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 40D 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.
Despite having a slightly smaller sensor, the 40D offers a higher resolution of 10.1 megapixel, compared with 6.3 MP of the 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 5.73μm versus 7.38μm for the 10D). However, it should be noted that the 40D is much more recent (by 4 years and 5 months) than the 10D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
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 consideration, the 40D has a markedly higher DXO score than the 10D (overall score 7 points higher), which will translate into better image quality. The advantage is based on 1 bits higher color depth, 0.4 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.

Beyond body and sensor, cameras can and do differ across a range of features. The 10D and the 40D 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 10D and Canon 40D 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 10D and the 40D have been discontinued, but can regularly be found used on ebay. The 10D was replaced by the Canon 20D, while the 40D was followed by the Canon 50D.
So what is the bottom line? Which of the two cameras – the Canon 10D or the Canon 40D – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Canon EOS 10D:
- More heavily discounted: Has been available for much longer (launched in February 2003).
Arguments in favor of the Canon EOS 40D:
- More detail: Has more megapixels (10.1 vs 6.3MP), which boosts linear resolution by 27%.
- Better image quality: Scores markedly higher (7 points) in the DXO overall evaluation.
- Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (230k vs 118k dots).
- Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
- Faster burst: Shoots at higher frequency (6.5 vs 3 flaps/sec) to capture the decisive moment.
- Longer lasting: Gets more shots (750 versus 500) out of a single battery charge.
- More affordable: Was introduced into a lower priced category (35 percent cheaper at launch).
- More modern: Reflects 4 years and 5 months of technical progress since the 10D launch.
If the count of individual advantages (bullet points above) is taken as a guide, the 40D is the clear winner of the contest (9 : 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.
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 10D or the 40D. 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. This is where reviews by experts come in. 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
In case you are interested in seeing how other cameras pair up, just make a corresponding selection in the search boxes below. There is also a set of direct links to comparison reviews that other users of the CAM-parator app explored. If you cannot find the camera you are interested in, please send me an email, and I will try to add information on that model to the database.
