Canon 1Ds Mark III versus Canon 7D

The Canon EOS-1Ds Mark III and the Canon EOS 7D are two digital cameras that were announced, respectively, in August 2007 and September 2009. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (1Ds Mark III) and an APS-C (7D) sensor. The 1Ds Mark III has a resolution of 21 megapixel, whereas the 7D provides 17.9 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 Mark III vs Canon 7D

The side-by-side display below illustrates the physical size and weight of the Canon 1Ds Mark III and the Canon 7D. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size 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 1Ds Mark III – 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 7D is considerably smaller (32 percent) than the Canon 1Ds Mark III. Moreover, the 7D is substantially lighter (38 percent) than the 1Ds Mark III. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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 Mark III) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (7D). You can find a comprehensive overview of suitable optics in the Canon EF Lens Catalog.

Concerning battery life, the 1Ds Mark III gets 1800 shots out of its LP-E4 battery, while the 7D can take 800 images on a single charge of its LP-E6 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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 camera comparisons there.

The camera’s price is obviously a critical decision-making factor. 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 7D was launched at a markedly lower price (by 79 percent) than the 1Ds Mark III, 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 Mark III vs Canon 7D

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 1Ds Mark III features a full frame sensor and the Canon 7D an APS-C sensor. The sensor area in the 7D 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.

Canon 1Ds Mark III and Canon 7D sensor measures

With 21MP, the 1Ds Mark III offers a higher resolution than the 7D (17.9MP), but the 1Ds Mark III nevertheless has larger individual pixels (pixel pitch of 6.41μm versus 4.31μm for the 7D) due to its larger sensor. However, the 7D is a somewhat more recent model (by 2 years) than the 1Ds Mark III, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

1Ds Mark III versus 7D MP

Consistent information on actual sensor performance is available from DXO Mark for many 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 1Ds Mark III provides substantially higher image quality than the 7D, with an overall score that is 14 points higher. This advantage is based on 2 bits higher color depth, 0.3 EV in additional 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.

Many modern cameras cannot only take still pictures, but also record videos. The 7D indeed provides for movie recording, while the 1Ds Mark III does not. The highest resolution format that the 7D can use is 1080/30p.

 

Feature comparison: Canon 1Ds Mark III vs Canon 7D

Apart from body and sensor, cameras can and do differ across a variety of features. The 1Ds Mark III and the 7D 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 1Ds Mark III and Canon 7D along with similar information for a selection of comparators.

Review summary: Canon 1Ds Mark III vs Canon 7D

So how do things add up? Which of the two cameras – the Canon 1Ds Mark III or the Canon 7D – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.


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

  • More detail: Offers more megapixels (21 vs 17.9MP) with a 8% higher linear resolution.
  • Better image quality: Scores substantially higher (14 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (2 bits more color depth).
  • Better low-light sensitivity: Requires less light for good images (1 stops ISO advantage).
  • Longer lasting: Can take more shots (1800 versus 800) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in August 2007).


Advantages of the Canon EOS 7D:

  • Broader imaging potential: Can capture not only stills but also 1080/30p video.
  • More detailed LCD: Has a higher resolution rear screen (920k vs 230k dots).
  • Faster burst: Shoots at higher frequency (8 vs 5 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (148x111mm vs 150x160mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 525g or 38 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 (79 percent cheaper at launch).
  • More modern: Reflects 2 years of technical progress since the 1Ds Mark III launch.

If the count of individual advantages (bullet points above) is taken as a guide, the 7D emerges as the winner of the match-up (8 : 6 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 Mark III 06:08 7D

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 1Ds Mark III or the 7D. 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 where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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.
