Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Cyber-shot DSC-RX100 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

The side-by-side display below illustrates the physical size and weight of the Sony RX100 and the Canon 1D X Mark II. 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 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 (349 percent) than the Sony RX100. It is noteworthy in this context that the 1DX Mark II is splash and dust-proof, while the RX100 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX100 has a lens built in, whereas the 1DX Mark II is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the 1DX Mark II and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the RX100 gets 330 shots out of its Sony NP-BX1 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. The power pack in the RX100 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

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.

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 RX100 was launched at a lower price than the 1DX Mark II, despite having a lens built in. 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 size of the imaging sensor is a crucial determinant 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Sony RX100 features an one-inch sensor and the Canon 1D X Mark II a full frame sensor. The sensor area in the 1DX Mark II is 645 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Even though the 1DX Mark II has a larger sensor, both cameras offer the same resolution of 20 megapixels. This implies that the 1DX Mark II has a lower pixel density and larger individual pixels (with a pixel pitch of 6.57μm versus 2.41μm for the RX100), which gives it a potential advantage in terms of light gathering capacity. In addition, the 1DX Mark II is much more recent (by 3 years and 7 months) than the RX100, and its sensor will have benefitted from technological advances during this time.

The 1DX Mark II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Sony Cyber-shot DSC-RX100 has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-25600. 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 1DX Mark II offers substantially better image quality than the RX100 (overall score 22 points higher). The advantage is based on 1.5 bits higher color depth, 1.1 EV in additional dynamic range, and 3 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the 1DX Mark II provides a better video resolution than the RX100. It can shoot movie footage at 4K/60p, while the Sony is limited to 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 1DX Mark II has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the RX100 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Sony RX100, the Canon 1D X Mark II, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The RX100 has one, while the 1DX Mark II does not. While the built-in flash of the RX100 is not very powerful, it can at times be useful as a fill-in light.

The RX100 writes its imaging data to SDXC or Memory Stick PRO Duo 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 RX100 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 Sony Cyber-shot DSC-RX100 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 1DX Mark II has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The RX100 does not feature such a mic input.

Studio photographers will appreciate that the Canon 1D X Mark II (unlike the RX100) 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 RX100 and the 1DX Mark II have been discontinued, but can regularly be found used on ebay. The RX100 was replaced by the Sony RX100 II, while the 1DX Mark II was followed by the Canon 1DX Mark III. Further information on the features and operation of the RX100 and 1DX Mark II can be found, respectively, in the Sony RX100 Manual (free pdf) or the online Canon 1D X Mark II Manual.

Review summary

So what is the bottom line? Is the Sony RX100 better than the Canon 1D X Mark II or vice versa? Below is a summary of the relative strengths of each of the two contestants.

If the number of relative strengths (bullet points above) is taken as a guide, the 1DX Mark II is the clear winner of the contest (25 : 8 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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 Sony RX100 and the Canon 1D X Mark II place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the RX100 or the 1DX Mark II 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 adjacent summary-table relays the overall verdicts of several of the most popular 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
