Body comparison: Canon 5D Mark III vs 1DX
An illustration of the physical size and weight of the Canon 5D Mark III and the Canon 1D X is provided in the side-by-side display below. 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 X is considerably larger (51 percent) than the Canon 5D Mark III. Moreover, the 1DX is substantially heavier (63 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 LP-E6 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, the 1DX 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).

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 49 percent) than the 1DX, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.
Sensor comparison: Canon 5D Mark III vs 1DX
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.
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.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
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 17.9 MP of the 1DX. This megapixels advantage translates into a 11 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 6.95μm for the 1DX). In this context, it should be noted, however, that the 5D Mark III is a somewhat more recent model (by 4 months) than the 1DX, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.
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-1D X are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800..
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

It is notable that the 5D Mark III has a headphone jack, which is not present on the 1DX This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.
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 1DX have been discontinued, but can regularly be found used on eBay. The 1DX was replaced by the Canon 1DX Mark II, while the 5D Mark III was followed by the Canon 5D Mark IV.
Review summary: Canon 5D Mark III vs 1DX
So how do things add up? Which of the two cameras – the Canon 5D Mark III or the Canon 1D X – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Canon EOS 5D Mark III:
- More detail: Offers more megapixels (22.1 vs 17.9MP) with a 11% higher linear resolution.
- Better sound control: Has a headphone port that enables audio monitoring while recording.
- More compact: Is smaller (152x116mm vs 158x168mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 601g or 39 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced category (49 percent cheaper at launch).
- More modern: Is somewhat more recent (announced 4 months after the 1DX).
Reasons to prefer the Canon EOS-1D X:
- Faster burst: Shoots at higher frequency (14 vs 6 flaps/sec) to capture the decisive moment.
- More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
- Longer lasting: Gets more shots (1120 versus 950) out of a single battery charge.
- More heavily discounted: Has been on the market for longer (launched in October 2011).
If the count of individual advantages (bullet points above) is taken as a guide, the 5D Mark III emerges as the winner of the contest (6 : 4 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.
In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 5D Mark III or the 1DX. 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.

Care should be taken when interpreting the review scores above, 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
