Canon 1Ds versus Canon 40D

The Canon EOS-1Ds and the Canon EOS 40D are two digital cameras that were officially introduced, respectively, in September 2002 and August 2007. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (1Ds) and an APS-C (40D) sensor. The 1Ds has a resolution of 11 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 1Ds vs Canon 40D

An illustration of the physical size and weight of the Canon 1Ds and the Canon 40D is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures 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 – the 1Ds – 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 considerably smaller (36 percent) than the Canon 1Ds. Moreover, the 40D is substantially lighter (35 percent) than the 1Ds. It is worth mentioning in this context that the 1Ds 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 1Ds) 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.

Concerning battery life, the 1Ds gets 600 shots out of its NP-E3 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 1Ds has a battery grip build 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).

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

The camera’s price is obviously a critical decision-making factor. The listed launch 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 86 percent) than the 1Ds, 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.

 

Sensor comparison: Canon 1Ds vs Canon 40D

The size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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.

Of the two cameras under consideration, the Canon 1Ds features a full frame sensor and the Canon 40D an APS-C sensor. The sensor area in the 40D is 61 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 1Ds (DIGIC), with benefits for noise reduction, color accuracy, and processing speed.

Canon 1Ds and Canon 40D sensor measures

With 11MP, the 1Ds offers a slightly higher resolution than the 40D (10.1MP), but the 1Ds nevertheless has larger individual pixels (pixel pitch of 8.83μm versus 5.73μm for the 40D) due to its larger sensor. However, the 40D is a somewhat more recent model (by 4 years and 10 months) than the 1Ds, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

1Ds versus 40D MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

The 40D offers Live View, so that it can project the live image that the sensor receives onto the rear screen for framing. The 1Ds lacks this capability. Both cameras are still-image focused and cannot record videos.
 

Feature comparison: Canon 1Ds vs Canon 40D

Beyond body and sensor, cameras can and do differ across a range of features. The 1Ds 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 table below summarizes some of the other core capabilities of the Canon 1Ds and Canon 40D in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

One difference between the cameras concerns the presence of an on-board flash. The 40D has one, while the 1Ds 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 1Ds and the 40D write their imaging data to Compact Flash cards. The 1Ds features dual card slots, which can be very useful in case a memory card fails. In contrast, the 40D only has one slot.

Review summary: Canon 1Ds vs Canon 40D

So what is the bottom line? Which of the two cameras – the Canon 1Ds or the Canon 40D – has the upper hand? The listing below highlights the relative strengths of the two models.


Reasons to prefer the Canon EOS-1Ds:

  • Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • 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 available for much longer (launched in September 2002).


Advantages of the Canon EOS 40D:

  • Better jpgs: Has a more modern image processing engine (DIGIC 3 vs DIGIC).
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (230k vs 120k dots).
  • Faster burst: Shoots at higher frequency (6.5 vs 3 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (146x108mm vs 156x157.6mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 443g or 35 percent) and is thus easier to take along.
  • Longer lasting: Gets more shots (750 versus 600) 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 (86 percent cheaper at launch).
  • More modern: Reflects 4 years and 10 months of technical progress since the 1Ds launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 40D is the clear winner of the contest (10 : 5 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera.

1Ds 05:10 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 1Ds or the 40D handle or perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog). The detailed reviews can be accessed by clicking on the site logo in the table header.

The review scores listed above should be treated with care, 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.
