Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1Ds Mark III and the Nikon D7000? 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 1Ds Mark III and the Nikon D7000 are illustrated 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D7000 is considerably smaller (42 percent) than the Canon 1Ds Mark III. Moreover, the D7000 is substantially lighter (44 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 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 (1Ds Mark III) and the Nikon Lens Catalog (D7000).

Concerning battery life, the 1Ds Mark III gets 1800 shots out of its Canon LP-E4 battery, while the D7000 can take 1050 images on a single charge of its Nikon EN-EL15 power pack. As can be seen in the images above, the 1Ds 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 D7000, Nikon provides the MB-D11 vertical grip as an optional accessory (see here on ebay).

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

Any camera decision will naturally be influenced heavily by the price. 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 D7000 was launched at a markedly lower price (by 81 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

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 1Ds Mark III features a full frame sensor and the Nikon D7000 an APS-C sensor. The sensor area in the D7000 is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 21MP, the 1Ds Mark III offers a higher resolution than the D7000 (16.1MP), but the 1Ds Mark III nevertheless has larger individual pixels (pixel pitch of 6.41μm versus 4.80μm for the D7000) due to its larger sensor. However, the D7000 is a much more recent model (by 3 years) than the 1Ds Mark III, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Canon 1Ds Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 1Ds Mark III for good quality output (200 dots per inch) amounts to 28.1 x 18.7 inches or 71.3 x 47.5 cm, for very good quality (250 dpi) 22.5 x 15 inches or 57.1 x 38 cm, and for excellent quality (300 dpi) 18.7 x 12.5 inches or 47.5 x 31.7 cm. The corresponding values for the Nikon D7000 are 24.6 x 16.3 inches or 62.6 x 41.5 cm for good quality, 19.7 x 13.1 inches or 50.1 x 33.2 cm for very good quality, and 16.4 x 10.9 inches or 41.7 x 27.6 cm for excellent quality prints.

The Canon EOS-1Ds Mark III has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 50-3200. The corresponding ISO settings for the Nikon D7000 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-25600.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 are not only capable of taking still images, but can also record movies. The D7000 indeed provides for movie recording, while the 1Ds Mark III does not. The highest resolution format that the D7000 can use is 1080/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 1Ds Mark III and the D7000 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 1Ds Mark III has a higher magnification than the one of the D7000 (0.76x vs 0.63x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 1Ds Mark III and Nikon D7000 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The D7000 has one, while the 1Ds Mark III does not. While the built-in flash of the D7000 is not very powerful, it can at times be useful as a fill-in light.

The Nikon D7000 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 1Ds Mark III writes its imaging data to Compact Flash or SDHC cards, while the D7000 uses SDXC 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-1Ds Mark III and Nikon D7000 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 1Ds Mark III (unlike the D7000) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 1Ds Mark III and the D7000 have been discontinued, but can regularly be found used on ebay. The 1Ds Mark III was replaced by the Canon 1DX, while the D7000 was followed by the Nikon D7100. Further information on the features and operation of the 1Ds Mark III and D7000 can be found, respectively, in the Canon 1Ds Mark III Manual (free pdf) or the online Nikon D7000 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Canon 1Ds Mark III and the Nikon D7000? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Canon EOS-1Ds Mark III:

• More detail: Offers more megapixels (21 vs 16.1MP) with a 14% higher linear resolution.
• Better low-light sensitivity: Requires less light for good images (0.5 stops ISO advantage).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.76x vs 0.63x).
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Can take more shots (1800 versus 1050) on a single battery charge.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• More heavily discounted: Has been available for much longer (launched in August 2007).

Reasons to prefer the Nikon D7000:

• More dynamic range: Captures a broader range of light and dark details (1.9 EV of extra DR).
• Broader imaging potential: Can capture not only stills but also 1080/24p video.
• More detailed LCD: Has a higher resolution rear screen (921k vs 230k dots).
• Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More compact: Is smaller (132x105mm vs 150x160mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 605g or 44 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 (81 percent cheaper at launch).
• More modern: Reflects 3 years of technical progress since the 1Ds Mark III launch.

If the count of relative strengths (bullet points above) is taken as a measure, the D7000 emerges as the winner of the match-up (10 : 7 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 1Ds Mark III and the Nikon D7000 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 technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the 1Ds Mark III and the D7000 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
