Canon 1D Mark III vs 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 megapixels, whereas the Nikon provides 12.1 MP.

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 Nikon D3? 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 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.

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 compare the optics available 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 built 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. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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

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.

The resolution advantage of the Nikon D3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D3 for good quality output (200 dots per inch) amounts to 21.3 x 14.2 inches or 54.1 x 36 cm, for very good quality (250 dpi) 17 x 11.3 inches or 43.2 x 28.8 cm, and for excellent quality (300 dpi) 14.2 x 9.4 inches or 36 x 24 cm. The corresponding values for the Canon 1D Mark III are 19.4 x 13 inches or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inches or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inches or 32.9 x 21.9 cm for excellent quality prints.

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 Nikon D3 are ISO 200 to ISO 6400, with the possibility to increase the ISO range to 100-25600.

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

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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the D3 has a higher magnification than the one of the 1D Mark III (0.70x 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 Nikon D3 along with similar information for a selection of comparators.

The Nikon D3 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

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.

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 Nikon D3 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 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. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Nikon websites.

Review summary

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).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.58x).
• More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• 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 (8 : 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. 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.

How about other alternatives? Do the specifications of the Canon 1D Mark III and the Nikon D3 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 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.

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.

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.
