Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1D X and the Canon EOS 5D Mark IV? 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

An illustration of the physical size and weight of the Canon 1D X and the Canon 5D Mark IV is provided 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 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 5D Mark IV is considerably smaller (34 percent) than the Canon 1D X. Moreover, the 5D Mark IV is substantially lighter (43 percent) than the 1DX. 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 1DX gets 1120 shots out of its Canon LP-E4N battery, while the 5D Mark IV can take 900 images on a single charge of its Canon LP-E6N 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 IV, Canon provides the BG-E20 vertical grip as an optional accessory (see here on ebay).

Any camera decision will naturally be influenced heavily by the price. 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 5D Mark IV was launched at a markedly lower price (by 49 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. 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.

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.

While the two cameras under review share the same sensor size, the 5D Mark IV offers a higher resolution of 30.1 megapixels, compared with 17.9 MP of the 1DX. This megapixels advantage translates into a 30 percent gain in linear resolution. On the other hand, these sensor specs imply that the 5D Mark IV has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 5.36μm versus 6.95μm for the 1DX). However, it should be noted that the 5D Mark IV is much more recent (by 4 years and 10 months) than the 1DX, 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 IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 5D Mark IV for good quality output (200 dots per inch) amounts to 33.6 x 22.4 inches or 85.3 x 56.9 cm, for very good quality (250 dpi) 26.9 x 17.9 inches or 68.3 x 45.5 cm, and for excellent quality (300 dpi) 22.4 x 14.9 inches or 56.9 x 37.9 cm. The corresponding values for the Canon 1D X are 25.9 x 17.3 inches or 65.8 x 43.9 cm for good quality, 20.7 x 13.8 inches or 52.7 x 35.1 cm for very good quality, and 17.3 x 11.5 inches or 43.9 x 29.3 cm for excellent quality prints.

The 5D Mark IV has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS-1D X has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-204800. The corresponding ISO settings for the Canon EOS 5D Mark IV are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 50-102400.

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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under consideration, the 5D Mark IV has a markedly higher DXO score than the 1DX (overall score 9 points higher), which will translate into better image quality. The advantage is based on 1 bits higher color depth, 1.8 EV in additional dynamic range, and 0.1 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the 5D Mark IV provides a better video resolution than the 1DX. It can shoot movie footage at 4K/30p, while the 1DX is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 1DX and the 5D Mark IV 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 5D Mark IV (0.76x vs 0.71x), 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 X, the Canon 5D Mark IV, and comparable cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 5D Mark IV has a touchscreen, while the 1DX has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Canon 5D Mark IV 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 1DX writes its imaging data to Compact Flash cards, while the 5D Mark IV uses Compact Flash or 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-1D X and Canon EOS 5D Mark IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 5D Mark IV offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 1DX does not provide wifi capability.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Travel and landscape photographers will find it useful that the 5D Mark IV has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

The 5D Mark IV is a recent model that features in the current product line-up of Canon. In contrast, the 1DX has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the 1DX was succeeded by the Canon 1DX Mark II. Further information on the features and operation of the 1DX and 5D Mark IV can be found, respectively, in the Canon 1D X Manual (free pdf) or the online Canon 5D Mark IV Manual.

Review summary

So how do things add up? Is the Canon 1D X better than the Canon 5D Mark IV or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon EOS-1D X:

• Larger viewfinder image: Features a viewfinder with a higher magnification (0.76x vs 0.71x).
• Faster burst: Shoots at higher frequency (14 vs 7 flaps/sec) to capture the decisive moment.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Can take more shots (1120 versus 900) on a single battery charge.
• More heavily discounted: Has been available for much longer (launched in October 2011).

Arguments in favor of the Canon EOS 5D Mark IV:

• More detail: Has more megapixels (30.1 vs 17.9MP), which boosts linear resolution by 30%.
• Better image quality: Scores markedly higher (9 points) in the DXO overall evaluation.
• More dynamic range: Captures a broader range of light and dark details (1.8 EV of extra DR).
• Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Better sound control: Has a headphone port that enables audio monitoring while recording.
• More detailed LCD: Has a higher resolution rear screen (1620k vs 1040k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More compact: Is smaller (151x116mm vs 158x168mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 661g or 43 percent) and is thus easier to take along.
• Easier geotagging: Features an internal GPS sensor to log localization data.
• Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced into a lower priced category (49 percent cheaper at launch).
• More modern: Reflects 4 years and 10 months of technical progress since the 1DX launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 5D Mark IV is the clear winner of the contest (17 : 5 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 X and the Canon 5D Mark IV 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 1DX or the 5D Mark IV. 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 why expert reviews are important. 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The review scores listed above should be treated 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 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.
