Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1D and the Canon EOS-1D Mark III? 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 and the Canon 1D Mark III. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side 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 Canon 1D and the Canon 1D Mark III are of equal size. However, the 1D Mark III is markedly lighter (27 percent) than the 1D. 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 1D gets 500 shots out of its NP-E3 battery, while the 1D Mark III can take 2200 images on a single charge of its LP-E4 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 table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 launched at a markedly lower price (by 31 percent) than the 1D, 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 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 more expensive and lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature an APS-H sensor, but their sensors differ slightly in size. The sensor area in the 1D Mark III is 4 percent smaller. They nevertheless have the same format factor of 1.3. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, the 1D Mark III uses a more advanced image processing engine (DIGIC III) than the 1D (DIGIC), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a slightly smaller sensor, the 1D Mark III offers a higher resolution of 10.1 megapixels, compared with 4.1 MP of the 1D. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 7.21μm versus 11.56μm for the 1D). However, it should be noted that the 1D Mark III is much more recent (by 5 years and 4 months) than the 1D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Canon 1D Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 1D Mark III for good quality output (200 dots per inch) amounts to 19.4 x 13 inches or 49.4 x 32.9 cm, for very good quality (250 dpi) 15.6 x 10.4 inches or 39.5 x 26.3 cm, and for excellent quality (300 dpi) 13 x 8.6 inches or 32.9 x 21.9 cm. The corresponding values for the Canon 1D are 12.5 x 8.3 inches or 31.7 x 21.1 cm for good quality, 10 x 6.6 inches or 25.4 x 16.9 cm for very good quality, and 8.3 x 5.5 inches or 21.1 x 14.1 cm for excellent quality prints.
The Canon EOS-1D has a native sensitivity range from ISO 200 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Canon EOS-1D Mark III are ISO 100 to ISO 3200, with the possibility to increase the ISO range to 50-6400.
In terms of underlying technology, the 1D is build around a CCD sensor, while the 1D Mark III uses a CMOS imager. 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Feature comparison
Apart from body and sensor, cameras can and do differ across a variety of features. The 1D and the 1D Mark III 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 1D Mark III has a higher magnification than the one of the 1D (0.58x vs 0.55x), 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 1D, the Canon 1D Mark III, and comparable cameras.

The 1D writes its imaging data to Compact Flash cards, while the 1D Mark III uses Compact Flash or SDHC cards. The 1D Mark III features dual card slots, which can be very useful in case a memory card fails. In contrast, the 1D only has one slot.
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.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.
Both the 1D and the 1D Mark III have been discontinued, but can regularly be found used on ebay. The 1D was replaced by the Canon 1D Mark II, while the 1D Mark III was followed by the Canon 1D Mark IV. Further information on the features and operation of the 1D and 1D Mark III can be found, respectively, in the Canon 1D Manual (free pdf) or the online Canon 1D Mark III Manual.
Review summary
So what conclusions can be drawn? Which of the two cameras – the Canon 1D or the Canon 1D Mark III – 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.
Arguments in favor of the Canon EOS-1D:
- Faster shutter: Has higher mechanical shutter speed (1/16000s vs 1/8000s) to freeze action.
- More heavily discounted: Has been available for much longer (launched in September 2001).
Reasons to prefer the Canon EOS-1D Mark III:
- More detail: Has more megapixels (10.1 vs 4.1MP), which boosts linear resolution by 56%.
- Better jpgs: Has a more modern image processing engine (DIGIC III vs DIGIC).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.58x vs 0.55x).
- Larger screen: Has a bigger rear LCD (3.0" vs 2.0") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (230k vs 120k dots).
- Faster burst: Shoots at higher frequency (10 vs 8 flaps/sec) to capture the decisive moment.
- Less heavy: Has a lower weight (by 430g or 27 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (2200 versus 500) out of a single battery charge.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More affordable: Was introduced into a lower priced category (31 percent cheaper at launch).
- More modern: Reflects 5 years and 4 months of technical progress since the 1D launch.
If the count of individual advantages (bullet points above) is taken as a guide, the 1D Mark III is the clear winner of the contest (11 : 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 and the Canon 1D Mark III 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 remains incomplete and does no justice, for example, to the way the 1D or the 1D Mark III perform in practice. 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 above review scores should be interpreted 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, please note that some of the review sites have changed their methodology and reporting over time.
