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 (40D) sensor. The 5D has a resolution of 12.7 megapixel, whereas the 40D provides 10.1 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 5D vs Canon 40D

The side-by-side display below illustrates the physical size and weight of the Canon 5D and the Canon 40D. 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 width, height and depth dimensions are rounded to the nearest millimeter. You can also toggle the display 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 – the 5D – 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 notably smaller (8 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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. Alternatively, you can also navigate to the CAM-parator app and make your selection from the full list of cameras there.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The 40D was launched at a markedly lower price (by 61 percent) than the 5D, 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.

 

Sensor comparison: Canon 5D vs Canon 40D

The size of the sensor inside a digital camera is one of the key determinants 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras 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.

Technology-wise, the 40D uses a more advanced image processing engine (DIGIC 3) than the 5D (DIGIC 2), with benefits for noise reduction, color accuracy, and processing speed.

Canon 5D and Canon 40D sensor measures

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.

5D versus 40D MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

The 40D offers Live View, so that it can project the live image that the sensor receives onto the rear screen for framing. The 5D lacks this capability. Both cameras are still-image focused and cannot record videos.
 

Feature comparison: Canon 5D vs Canon 40D

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 following table reports on some other key feature differences and similarities of the Canon 5D, the Canon 40D, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

One difference between the cameras concerns the presence of an on-board flash. The 40D has one, while the 5D does not. While the build-in flash of the 40D is not very powerful, it can at times be useful as a fill-in light.

Both the 5D and the 40D write their imaging data to Compact Flash cards.

Review summary: Canon 5D vs Canon 40D

So what is the bottom line? Is the Canon 5D better than the Canon 40D or vice versa? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor 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).


Reasons to prefer the Canon EOS 40D:

  • Better jpgs: Has a more modern image processing engine (DIGIC 3 vs DIGIC 2).
  • 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.
  • 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 before making a camera decision.

5D 05:07 40D

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 5D or the 40D 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. This is why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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