Canon 1D X Mark II vs Leica SL2
The Canon EOS-1D X Mark II and the Leica SL2 are two digital cameras that were announced, respectively, in February 2016 and November 2019. The 1DX Mark II is a DSLR, while the SL2 is a mirrorless interchangeable lens camera. Both cameras are equipped with a full frame sensor. The Canon has a resolution of 20 megapixels, whereas the Leica provides 46.7 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 Leica SL2? 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 physical size and weight of the Canon 1D X Mark II and the Leica SL2 are illustrated 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 Leica SL2 is considerably smaller (41 percent) than the Canon 1D X Mark II. Moreover, the SL2 is substantially lighter (38 percent) than the 1DX Mark II. 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.
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 SL2, Leica provides the HG-SCL6 vertical grip as an optional accessory (see here on eBay). The power pack in the SL2 can be charged via the USB port, which can be very convenient when travelling.

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 two cameras under review were launched at the same price and fall into the same 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.
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. 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.
In terms of underlying technology, both cameras are build around CMOS sensors.
While the two cameras under review share the same sensor size, the SL2 offers a higher resolution of 46.7 megapixels, compared with 20 MP of the 1DX Mark II. This megapixels advantage translates into a 53 percent gain in linear resolution. On the other hand, these sensor specs imply that the SL2 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.30μm versus 6.57μm for the 1DX Mark II). However, it should be noted that the SL2 is much more recent (by 3 years and 9 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. Coming back to sensor resolution, it should be mentioned that the SL2 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Leica SL2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SL2 for good quality output (200 dots per inch) amounts to 41.8 x 27.9 inches or 106.3 x 70.9 cm, for very good quality (250 dpi) 33.5 x 22.3 inches or 85 x 56.7 cm, and for excellent quality (300 dpi) 27.9 x 18.6 inches or 70.8 x 47.3 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 1DX Mark II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
Unlike the 1DX Mark II, the SL2 has the capacity to capture high quality composite images (187MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
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 Leica SL2 are ISO 100 to ISO 50000, with the possibility to increase the ISO range to 50-50000.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar 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, and both provide the same movie specifications (4K/60p).
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the SL2 has an electronic viewfinder (5760k 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%), but the viewfinder of the SL2 has a higher magnification than the one of the 1DX Mark II (0.78x vs 0.76x), 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 Mark II, the Leica SL2, and comparable cameras.

One feature that differentiates the SL2 and the 1DX Mark II is in-body image stabilization (IBIS). The SL2 reduces the risk of handshake-induced blur with all attached lenses, while the 1DX Mark II offers no blur reduction with lenses that themselves do not provide optical image stabilization.
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 SL2 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 Leica SL2 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 Mark II writes its imaging data to Compact Flash or CFast cards, while the SL2 uses SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.
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 Leica SL2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SL2 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 1DX Mark II 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 1DX Mark II has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
The SL2 is a recent model that features in the current product line-up of Leica. In contrast, the 1DX Mark II has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the 1DX Mark II was succeeded 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 and Leica websites.
So what is the bottom line? Is there a clear favorite between the Canon 1D X Mark II and the Leica SL2? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Canon EOS-1D X Mark II:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.

- Longer lasting: Can take more shots (1210 versus 370) on a single battery charge.
- Easier geotagging: Features an internal GPS sensor to log localization data.
- More heavily discounted: Has been available for much longer (launched in February 2016).
Arguments in favor of the Leica SL2:
- More detail: Has more megapixels (46.7 vs 20MP), which boosts linear resolution by 53%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- High quality composites: Can combine several shots after pixel-shifting its sensor.
- More framing info: Has an electronic viewfinder that displays shooting data.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.76x).
- More detailed LCD: Has a higher resolution rear screen (2100k vs 1620k dots).
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More compact: Is smaller (146x107mm vs 158x168mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 577g or 38 percent) and is thus easier to take along.
- Easier travel charging: Can be conveniently charged via its USB port.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More legacy lens friendly: Can use many 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 prestigious: Has the Leica luxury appeal, which ensures a high resale value.
- More modern: Reflects 3 years and 9 months of technical progress since the 1DX Mark II launch.
If the count of individual advantages (bullet points above) is taken as a guide, the SL2 is the clear winner of the contest (18 : 8 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 Mark II and the Leica SL2 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens 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 says little about, for example, the shooting experience and imaging performance of the 1DX Mark II and the SL2 in practical situations. 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.
This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
