Canon 1D Mark III vs 1DX
The Canon EOS-1D Mark III and the Canon EOS-1D X are two professional cameras that were officially introduced, respectively, in February 2007 and October 2011. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-H (1D Mark III) and a full frame (1DX) sensor. The 1D Mark III has a resolution of 10.1 megapixels, whereas the 1DX provides 17.9 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 Canon EOS-1D X? 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.
The physical size and weight of the Canon 1D Mark III and the Canon 1D X are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. 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 1D X is notably larger (8 percent) than the Canon 1D Mark III. Moreover, the 1DX is markedly heavier (34 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 (as in the 1DX) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (1D Mark III). You can compare the optics available in the Canon EF Lens Catalog.
Concerning battery life, the 1D Mark III gets 2200 shots out of its LP-E4 battery, while the 1DX can take 1120 images on a single charge of its LP-E4N 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.

Any camera decision will obviously take relative prices into account. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The 1D Mark III was launched at a markedly lower price (by 34 percent) than the 1DX, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 Canon 1D X a full frame sensor. The sensor area in the 1DX is 65 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.
With 17.9MP, the 1DX offers a higher resolution than the 1D Mark III (10.1MP), but the 1DX has smaller individual pixels (pixel pitch of 6.95μm versus 7.21μm for the 1D Mark III). Yet, the 1DX is a much more recent model (by 4 years and 7 months) than the 1D Mark III, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Canon 1D X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 1DX for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 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 Canon EOS-1D X are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.
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 consideration, the 1DX offers substantially better image quality than the 1D Mark III (overall score 11 points higher). The advantage is based on 1.1 bits higher color depth, 0.1 EV in additional dynamic range, and 1.4 stops in additional low light sensitivity. 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 cannot only take still pictures, but also record videos. The 1DX indeed provides for movie recording, while the 1D Mark III does not. The highest resolution format that the 1DX can use is 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. The 1D Mark III and the 1DX 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 1DX has a higher magnification than the one of the 1D Mark III (0.76x vs 0.58x), 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 Mark III, the Canon 1D X, and comparable cameras.

The 1D Mark III writes its imaging data to Compact Flash or SDHC cards, while the 1DX uses Compact Flash cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.
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 Canon EOS-1D X 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 1DX 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 1DX was followed by the Canon 1DX Mark II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So how do things add up? Is the Canon 1D Mark III better than the Canon 1D X or vice versa? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Canon EOS-1D Mark III:
- Less heavy: Is lighter (by 396g or 26 percent) and hence easier to carry around.
- Longer lasting: Can take more shots (2200 versus 1120) on a single battery charge.
- More affordable: Was introduced into a lower priced category (34 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in February 2007).
Reasons to prefer the Canon EOS-1D X:
- More detail: Has more megapixels (17.9 vs 10.1MP), which boosts linear resolution by 33%.
- Better image quality: Scores substantially higher (11 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.1 bits more color depth).
- Better low-light sensitivity: Can shoot in dim conditions (1.4 stops ISO advantage).
- Broader imaging potential: Can capture not only stills but also 1080/30p video.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.76x vs 0.58x).
- Larger screen: Has a bigger rear LCD (3.2" vs 3.0") 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 (14 vs 10 flaps/sec) to capture the decisive moment.
- More modern: Reflects 4 years and 7 months of technical progress since the 1D Mark III launch.
If the count of individual advantages (bullet points above) is taken as a guide, the 1DX is the clear winner of the contest (10 : 4 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 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 1D Mark III and the Canon 1D X 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 1DX in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
