Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 5D Mark III and the Canon EOS-1Ds Mark II? 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 5D Mark III and the Canon 1Ds Mark II. 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 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 Canon 1Ds Mark II is notably larger (40 percent) than the Canon 5D Mark III. Moreover, the 1Ds Mark II is markedly heavier (28 percent) than the 5D 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the 5D Mark III gets 950 shots out of its Canon LP-E6 battery, while the 1Ds Mark II can take 1200 images on a single charge of its Canon NP-E3 power pack. As can be seen in the images above, the 1Ds Mark II 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 5D Mark III, Canon provides the BG-E11 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. 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.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 5D Mark III was launched at a markedly lower price (by 56 percent) than the 1Ds Mark II, 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 imaging sensor is a crucial determinant 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. 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.

Both cameras under consideration feature a full frame sensor and have a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the review cameras among the large-sensor cameras that aim for top notch image quality. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

In terms of chip-set technology, the 5D Mark III uses a more advanced image processing engine (DIGIC 5+) than the 1Ds Mark II (DIGIC II), with benefits for noise reduction, color accuracy, and processing speed.

While the two cameras under review share the same sensor size, the 5D Mark III offers a higher resolution of 22.1 megapixels, compared with 16.6 MP of the 1Ds Mark II. This megapixels advantage translates into a 15 percent gain in linear resolution. On the other hand, these sensor specs imply that the 5D Mark III has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 6.25μm versus 7.21μm for the 1Ds Mark II). In this context, it should be noted, however, that the 5D Mark III is much more recent (by 7 years and 5 months) than the 1Ds Mark II, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

The resolution advantage of the Canon 5D Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 5D Mark III for good quality output (200 dots per inch) amounts to 28.8 x 19.2 inches or 73.2 x 48.8 cm, for very good quality (250 dpi) 23 x 15.4 inches or 58.5 x 39 cm, and for excellent quality (300 dpi) 19.2 x 12.8 inches or 48.8 x 32.5 cm. The corresponding values for the Canon 1Ds Mark II are 25 x 16.6 inches or 63.4 x 42.3 cm for good quality, 20 x 13.3 inches or 50.7 x 33.8 cm for very good quality, and 16.6 x 11.1 inches or 42.3 x 28.2 cm for excellent quality prints.

The Canon EOS 5D Mark III has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-102400. The corresponding ISO settings for the Canon EOS-1Ds Mark II are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 50-3200.

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.

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 5D Mark III has a notably higher overall DXO score than the 1Ds Mark II (overall score 7 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.7 bits higher color depth, 0.4 EV in additional dynamic range, and 0.6 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The 5D Mark III indeed provides movie recording capabilities, while the 1Ds Mark II does not. The highest resolution format that the 5D Mark III can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 5D Mark III and the 1Ds Mark II 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 5D Mark III has a higher magnification than the one of the 1Ds Mark II (0.71x vs 0.70x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon 5D Mark III, the Canon 1Ds Mark II, and comparable cameras.

The 5D Mark III writes its imaging data to Compact Flash or SDXC cards, while the 1Ds Mark II uses Compact Flash or SDHC 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 5D Mark III and Canon EOS-1Ds Mark II 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 5D Mark III and the 1Ds Mark II have been discontinued, but can regularly be found used on ebay. The 1Ds Mark II was replaced by the Canon 1Ds Mark III, while the 5D Mark III was followed by the Canon 5D Mark IV. Further information on the features and operation of the 5D Mark III and 1Ds Mark II can be found, respectively, in the Canon 5D Mark III Manual (free pdf) or the online Canon 1Ds Mark II Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon 5D Mark III or the Canon 1Ds Mark II – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon EOS 5D Mark III:

• More detail: Offers more megapixels (22.1 vs 16.6MP) with a 15% higher linear resolution.
• Better image quality: Scores markedly higher (7 points) in the DXO overall assessment.
• Better low-light sensitivity: Requires less light for good images (0.6 stops ISO advantage).
• Better jpgs: Has a more modern image processing engine (DIGIC 5+ vs DIGIC II).
• Broader imaging potential: Can record not only still images but also 1080/30p movies.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.71x vs 0.70x).
• Larger screen: Has a bigger rear LCD (3.2" vs 2.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
• Faster burst: Shoots at higher frequency (6 vs 4 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (152x116mm vs 156x158mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 265g or 22 percent) and hence easier to carry around.
• More affordable: Was introduced into a lower priced category (56 percent cheaper at launch).
• More modern: Reflects 7 years and 5 months of technical progress since the 1Ds Mark II launch.

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

• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Gets more shots (1200 versus 950) out of a single battery charge.
• More heavily discounted: Has been around for much longer (launched in September 2004).

If the number of relative strengths (bullet points above) is taken as a guide, the 5D Mark III is the clear winner of the match-up (13 : 3 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 5D Mark III and the Canon 1Ds Mark II 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 5D Mark III or the 1Ds Mark II. 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 (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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
