Canon 5D versus Canon 40D
The Canon EOS 5D and the Canon EOS 40D are two digital cameras that were announced, respectively, in August 2005 and August 2007. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (5D) and an APS-C sensor. The 5D has a resolution of 12.7 megapixel, whereas the 40D provides 10.1 MP.
The physical size and weight of the Canon 5D and the Canon 40D are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the 5D – represents the basis for the calculations 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 considerably smaller (91 percent) than the Canon 5D. Moreover, the 40D is markedly lighter (8 percent) than the 5D. It is worth mentioning in this context that the 5D is splash and dust resistant, while the 40D does not feature any corresponding weather-sealing.
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. A larger imaging sensor (as in the 5D) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (40D). You can find a comprehensive 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 61 percent) than the 5D, 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 size of the imaging sensor is a crucial determinant 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. 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.
Of the two cameras under consideration, the Canon 5D features a full frame sensor and the Canon 40D an APS-C sensor. The sensor area in the 40D is 62 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 12.7MP, the 5D offers a higher resolution than the 40D (10.1MP), but the 5D nevertheless has larger individual pixels (pixel pitch of 8.25μm versus 5.73μm for the 40D) due to its larger sensor. However, the 40D is a somewhat more recent model (by 2 years) than the 5D, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
Consistent information on actual sensor performance is available from DXO Mark for most 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"). Of the two cameras under review, the 5D has a notably higher overall DXO score than the 40D (overall score 7 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.8 bits higher color depth, 0.2 EV of lower dynamic range, and 1 stops in additional low light sensitivity. 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 variety of features. The 5D 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 5D and Canon 40D along with similar information for a selection of comparators. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the 5D and the 40D have been discontinued, but can regularly be found used on ebay. The 5D was replaced by the Canon 5D Mark II, while the 40D was followed by the Canon 50D.
So what conclusions can be drawn? Is the Canon 5D better than the Canon 40D or vice versa? The listing below highlights the relative strengths of the two models.
Advantages of the Canon EOS 5D:
- More detail: Offers more megapixels (12.7 vs 10.1MP) with a 12% higher linear resolution.
- Better image quality: Scores markedly higher (7 points) in the DXO overall assessment.
- Better low-light sensitivity: Requires less light for good images (1 stops ISO advantage).
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- More heavily discounted: Has been available for much longer (launched in August 2005).
Arguments in favor of the Canon EOS 40D:
- Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
- Faster burst: Shoots at higher frequency (6.5 vs 3 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (146x108mm vs 152x113mm) and will fit more readily into a bag.
- Longer lasting: Gets more shots (750 versus 400) out of a single battery charge.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced into a lower priced category (61 percent cheaper at launch).
- More modern: Reflects 2 years of technical progress since the 5D launch.
If the number of relative strengths (bullet points above) is taken as a guide, the 40D emerges as the winner of the match-up (7 : 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.
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 5D or the 40D handle or 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. This is why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major 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 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 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.
If you would like to see a different side-by-side camera review, just use the search menu below. There is also a set of direct links to comparison reviews that other users of the CAM-parator app explored. If you do not see the camera that you are looking for, kindly get in touch, and I will try to add information on that model to the database.
