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

An illustration of the physical size and weight of the Canon R and the Canon 1D X Mark II is provided 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 size 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 Mark II is considerably larger (95 percent) than the Canon R. Moreover, the 1DX Mark II is substantially heavier (132 percent) than the Canon R. 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the Canon R gets 370 shots out of its Canon LP-E6N battery, while the 1DX Mark II can take 1210 images on a single charge of its Canon LP-E19 power pack. As can be seen in the images above, the 1DX 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 Canon R, Canon provides the BG-E22 vertical grip as an optional accessory (see here on ebay). The power pack in the Canon R can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

Convert to Imperial

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Canon R was launched at a markedly lower price (by 62 percent) than the 1DX 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

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. 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. 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 tend to be more expensive and 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 Canon R offers a higher resolution of 30.1 megapixels, compared with 20 MP of the 1DX Mark II. This megapixels advantage translates into a 23 percent gain in linear resolution. On the other hand, these sensor specs imply that the Canon R has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 5.36μm versus 6.57μm for the 1DX Mark II). In this context, it should be noted, however, that the Canon R is much more recent (by 2 years and 7 months) than the 1DX 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 R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Canon R 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 Mark II are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.

The Canon EOS R has a native sensitivity range from ISO 100 to ISO 40000, which can be extended to ISO 50-102400. The corresponding ISO settings for the Canon EOS-1D X Mark II are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-409600.

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.

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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 1DX Mark II provides a faster frame rate than the Canon R. It can shoot movie footage at 4K/60p, while the Canon R is limited to 4K/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the Canon R has an electronic viewfinder (3690k dots), while the 1DX Mark II has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinders of both cameras offer the same field of view (100%), as well as the same magnification (0.76x). The table below summarizes some of the other core capabilities of the Canon R and Canon 1D X Mark II in connection with corresponding information for a sample of similar cameras.

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

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the Canon R is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Canon R writes its imaging data to SDXC cards, while the 1DX Mark II uses Compact Flash or CFast cards. The 1DX Mark II features dual card slots, which can be very useful in case a memory card fails. In contrast, the Canon R 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. The table below provides an overview of the connectivity of the Canon EOS R and Canon EOS-1D X Mark II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Canon R offers wifi support, while the 1DX Mark II does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Canon 1D X Mark II (unlike the Canon R) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Travel and landscape photographers will find it useful that the 1DX Mark II has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the Canon R and the 1DX Mark II have been discontinued, but can regularly be found used on ebay. The 1DX Mark II was replaced by the Canon 1DX Mark III, while the Canon R does not have a direct successor. Further information on the features and operation of the Canon R and 1DX Mark II can be found, respectively, in the Canon R Manual (free pdf) or the online Canon 1D X Mark II Manual.

Review summary

So how do things add up? Is there a clear favorite between the Canon R and the Canon 1D X Mark II? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Canon EOS R:

• More detail: Offers more megapixels (30.1 vs 20MP) with a 23% higher linear resolution.
• More framing info: Has an electronic viewfinder that displays shooting data.
• More detailed LCD: Has a higher resolution rear screen (2100k vs 1620k dots).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• More compact: Is smaller (139x98mm vs 158x168mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 870g or 57 percent) and hence easier to carry around.
• Easier travel charging: Can be conveniently charged via its USB port.
• More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More affordable: Was introduced into a lower priced category (62 percent cheaper at launch).
• More modern: Reflects 2 years and 7 months of technical progress since the 1DX Mark II launch.

Reasons to prefer the Canon EOS-1D X Mark II:

• Better video: Provides higher movie framerates (4K/60p versus 4K/30p).
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Faster burst: Shoots at higher frequency (16 vs 8 flaps/sec) to capture the decisive moment.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Gets more shots (1210 versus 370) out of a single battery charge.
• Easier geotagging: Features an internal GPS sensor to log localization data.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More heavily discounted: Has been around for much longer (launched in February 2016).

If the count of relative strengths (bullet points above) is taken as a measure, the Canon R is the clear winner of the match-up (14 : 9 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 R and the Canon 1D X Mark II place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings 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 says little about, for example, the shooting experience and imaging performance of the Canon R and the 1DX Mark II in practical situations. 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 where reviews by experts come in. 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 above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation.
