Canon 1D Mark III vs 40D

The Canon EOS-1D Mark III and the Canon EOS 40D are two digital cameras that were officially introduced, respectively, in February 2007 and August 2007. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-H (1D Mark III) and an APS-C (40D) sensor. Both cameras offer a resolution of 10.1 megapixels.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1D Mark III and the Canon EOS 40D? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

The physical size and weight of the Canon 1D Mark III and the Canon 40D 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.

Size Canon 1D Mark III vs Canon 40D
Compare 1D Mark III versus 40D top
Comparison 1D Mark III or 40D rear

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 (36 percent) than the Canon 1D Mark III. Moreover, the 40D is markedly lighter (29 percent) than the 1D Mark III. It is worth mentioning in this context that the 1D Mark III 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 1D Mark III) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (40D). You can compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the 1D Mark III gets 2200 shots out of its LP-E4 battery, while the 40D can take 750 images on a single charge of its BP-511A power pack. As can be seen in the images above, the 1D Mark III has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the 40D, Canon provides the BG-E2N vertical grip as an optional accessory (see here on eBay).

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The 40D was launched at a markedly lower price (by 71 percent) than the 1D Mark III, 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

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

Of the two cameras under consideration, the Canon 1D Mark III features an APS-H sensor and the Canon 40D an APS-C sensor. The sensor area in the 40D is 37 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 1D Mark III and Canon 40D sensor measures

Even though the 1D Mark III has a larger sensor, both cameras offer the same resolution of 10.1 megapixels. This implies that the 1D Mark III has a lower pixel density and larger individual pixels (with a pixel pitch of 7.21μm versus 5.73μm for the 40D), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the 40D is a somewhat more recent model (by 5 months) than the 1D Mark III, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

The Canon EOS-1D Mark III has a native sensitivity range from ISO 100 to ISO 3200, which can be extended to ISO 50-6400. The corresponding ISO settings for the Canon EOS 40D are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.

1D Mark III versus 40D MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under review, the 1D Mark III 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 0.6 bits higher color depth, 0.4 EV in additional dynamic range, and 0.6 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.

Both the 1D Mark III and the 40D offer Live View, so that they make it possible to use the rear screen for framing. Both cameras are still-image focused and cannot record videos.
 

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The 1D Mark III 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 viewfinder in the 1D Mark III offers a wider field of view (100%) than the one in the 40D (95%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the 40D has a higher magnification (0.59x vs 0.58x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon 1D Mark III and Canon 40D along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The 40D has one, while the 1D Mark III does not. While the built-in flash of the 40D is not very powerful, it can at times be useful as a fill-in light.

The 1D Mark III writes its imaging data to Compact Flash or SDHC cards, while the 40D uses Compact Flash cards. The 1D Mark III features dual card slots, which can be very useful in case a memory card fails. In contrast, the 40D only has one slot.

 

Connectivity comparison

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-1D Mark III and Canon EOS 40D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Both the 1D Mark III and the 40D have been discontinued, but can regularly be found used on eBay. The 1D Mark III was replaced by the Canon 1D Mark IV, while the 40D was followed by the Canon 50D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.


Review summary

So what is the bottom line? Which of the two cameras – the Canon 1D Mark III or the Canon 40D – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Canon EOS-1D Mark III:

  • Better image quality: Scores markedly higher (7 points) in the DXO overall assessment.
  • Better low-light sensitivity: Requires less light for good images (0.6 stops ISO advantage).
  • More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
  • Faster burst: Shoots at higher frequency (10 vs 6.5 flaps/sec) to capture the decisive moment.
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Longer lasting: Can take more shots (2200 versus 750) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been on the market for longer (launched in February 2007).


Advantages of the Canon EOS 40D:

  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.59x vs 0.58x).
  • More compact: Is smaller (146x108mm vs 156x157mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 333g or 29 percent) and is thus easier to take along.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (71 percent cheaper at launch).
  • More modern: Was introduced somewhat (5 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the 1D Mark III emerges as the winner of the contest (9 : 6 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. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

1D Mark III 09:06 40D

How about other alternatives? Do the specifications of the Canon 1D Mark III and the Canon 40D place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the 1D Mark III and the 40D in practical situations. 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.

Expert reviews

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
