Canon 1D Mark III versus Nikon D3

The Canon EOS-1D Mark III and the Nikon D3 are two professional cameras that were revealed to the public, 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 a full frame (D3) sensor. The Canon has a resolution of 10.1 megapixel, whereas the Nikon provides 12.1 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 1D Mark III vs Nikon D3

The side-by-side display below illustrates the physical size and weight of the Canon 1D Mark III and the Nikon D3. 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 1D 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 Nikon D3 is somewhat larger (3 percent) than the Canon 1D Mark III. Moreover, the D3 is markedly heavier (13 percent) than the 1D 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 will tend to go along with bigger and heavier lenses, although exceptions exist. You can find an overview of optics for the two cameras in the Canon EF Lens Catalog (1D Mark III) and the Nikon Lens Catalog (D3).

Concerning battery life, the 1D Mark III gets 2200 shots out of its LP-E4 battery, while the D3 can take 4300 images on a single charge of its EN-EL4a power pack. As can be seen in the images above, both cameras have a battery grip build in. This facilitates image-taking in portrait orientation and gives it additional battery power.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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 1D Mark III was somewhat cheaper (by 10 percent) than the D3 at launch, but both cameras fall into the same price category. 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 1D Mark III vs Nikon D3

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 Nikon D3 a full frame sensor. The sensor area in the D3 is 64 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

With 12.1MP, the D3 offers a higher resolution than the 1D Mark III (10.1MP), but the D3 nevertheless has larger individual pixels (pixel pitch of 8.43μm versus 7.21μm for the 1D Mark III) due to its larger sensor. Moreover, the D3 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 further enhance the light gathering capacity of its pixel-units.

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 consideration, the D3 has a markedly higher DXO score than the 1D Mark III (overall score 10 points higher), which will translate into better image quality. The advantage is based on 0.8 bits higher color depth, 0.5 EV in additional dynamic range, and 1.1 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Feature comparison: Canon 1D Mark III vs Nikon D3

Apart from body and sensor, cameras can and do differ across a variety of features. The 1D Mark III and the D3 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 1D Mark III and Nikon D3 along with similar information for a selection of comparators. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The 1D Mark III writes its imaging data to Compact Flash or SDHC cards, while the D3 uses Compact Flash cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.

Both the 1D Mark III and the D3 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 D3 was followed by the Nikon D4.

Review summary: Canon 1D Mark III vs Nikon D3

So what is the bottom line? Is the Canon 1D Mark III better than the Nikon D3 or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Canon EOS-1D Mark III:

• Less heavy: Is lighter (by 145g or 11 percent) and hence easier to carry around.
• More heavily discounted: Has been on the market for longer (launched in February 2007).

Arguments in favor of the Nikon D3:

• More detail: Has more megapixels (12.1 vs 10.1MP), which boosts linear resolution by 9%.
• Better image quality: Scores markedly higher (10 points) in the DXO overall evaluation.
• Better low-light sensitivity: Can shoot in dim conditions (1.1 stops ISO advantage).
• More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
• Longer lasting: Gets more shots (4300 versus 2200) out of a single battery charge.
• More modern: Was introduced somewhat (5 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the D3 is the clear winner of the contest (6 : 2 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the 1D Mark III and the D3 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. This is why expert reviews are important. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
