Canon 1D X Mark II vs SL1
The Canon EOS-1D X Mark II and the Canon EOS Rebel SL1 (labelled Canon 100D in some countries) are two digital cameras that were officially introduced, respectively, in February 2016 and March 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (1DX Mark II) and an APS-C (SL1) sensor. The 1DX Mark II has a resolution of 20 megapixels, whereas the SL1 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 X Mark II and the Canon EOS Rebel SL1? 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 side-by-side display below illustrates the physical size and weight of the Canon 1D X Mark II and the Canon SL1. 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.
The SL1 can be obtained in two different colors (black, white), while the 1DX Mark II is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon SL1 is considerably smaller (60 percent) than the Canon 1D X Mark II. Moreover, the SL1 is substantially lighter (73 percent) than the 1DX Mark II. It is worth mentioning in this context that the 1DX Mark II is splash and dust resistant, while the SL1 does not feature any corresponding weather-sealing.
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 Mark II) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (SL1). You can compare the optics available in the Canon EF Lens Catalog.
Concerning battery life, the 1DX Mark II gets 1210 shots out of its LP-E19 battery, while the SL1 can take 380 images on a single charge of its LP-E12 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 SL1, there are third party battery grips available as optional accessories (see here on eBay).

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 SL1 was launched at a markedly lower price (by 91 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.
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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 Canon 1D X Mark II features a full frame sensor and the Canon SL1 an APS-C sensor. The sensor area in the SL1 is 62 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 20MP, the 1DX Mark II offers a higher resolution than the SL1 (17.9MP), but the 1DX Mark II nevertheless has larger individual pixels (pixel pitch of 6.57μm versus 4.31μm for the SL1) due to its larger sensor. Moreover, the 1DX Mark II is a much more recent model (by 2 years and 10 months) than the SL1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon 1D X Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 1DX Mark II for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Canon SL1 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 Canon EOS-1D X Mark II has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-409600. The corresponding ISO settings for the Canon EOS Rebel SL1 are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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. Of the two cameras under review, the 1DX Mark II provides substantially higher image quality than the SL1, with an overall score that is 25 points higher. This advantage is based on 2.3 bits higher color depth, 2.2 EV in additional dynamic range, and 1.9 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. 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 higher video resolution than the SL1. It can shoot video footage at 4K/60p, while the SL1 is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The 1DX Mark II and the SL1 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 viewfinder in the 1DX Mark II offers a wider field of view (100%) than the one in the SL1 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 1DX Mark II has a higher magnification (0.76x vs 0.54x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 1D X Mark II and Canon SL1 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 1DX Mark II, but is missing on the SL1 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
The 1DX Mark II writes its imaging data to Compact Flash or CFast cards, while the SL1 uses SDXC cards. The 1DX Mark II features dual card slots, which can be very useful in case a memory card fails. In contrast, the SL1 only has one slot.
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 Mark II and Canon EOS Rebel SL1 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 headphone jack, which is not present on the SL1 This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.
Studio photographers will appreciate that the Canon 1D X Mark II (unlike the SL1) 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 1DX Mark II and the SL1 have been discontinued, but can regularly be found used on eBay. The SL1 was replaced by the Canon SL2, while the 1DX Mark II was followed by the Canon 1DX Mark III. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.

If the number of relative strengths (bullet points above) is taken as a guide, the 1DX Mark II is the clear winner of the match-up (22 : 5 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. 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 Mark II and the Canon SL1 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 remains incomplete and does no justice, for example, to the way the 1DX Mark II or the SL1 perform in practice. 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 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 (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.

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. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
