Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS M6 Mark II and the Leica S2? 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 M6 Mark II and the Leica S2 are illustrated in the side-by-side display below. 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 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 Leica S2 is considerably larger (129 percent) than the Canon M6 Mark II. Moreover, the S2 is substantially heavier (246 percent) than the M6 Mark II. It is noteworthy in this context that the S2 is splash and dust-proof, while the M6 Mark II 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. 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.
The power pack in the M6 Mark II can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

Any camera decision will obviously take relative prices into account. 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 M6 Mark II was launched at a markedly lower price (by 96 percent) than the S2, 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.
The size of the imaging sensor is a crucial determinant 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon M6 Mark II features an APS-C sensor and the Leica S2 a medium format sensor. The sensor area in the S2 is 299 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 0.8. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 37.5MP, the S2 offers a higher resolution than the M6 Mark II (32.3MP), but the S2 nevertheless has larger individual pixels (pixel pitch of 6.00μm versus 3.23μm for the M6 Mark II) due to its larger sensor. However, the M6 Mark II is a much more recent model (by 10 years and 11 months) than the S2, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the S2 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Leica S2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S2 for good quality output (200 dots per inch) amounts to 37.5 x 25 inches or 95.3 x 63.5 cm, for very good quality (250 dpi) 30 x 20 inches or 76.2 x 50.8 cm, and for excellent quality (300 dpi) 25 x 16.7 inches or 63.5 x 42.3 cm. The corresponding values for the Canon M6 Mark II are 34.8 x 23.2 inches or 88.4 x 58.9 cm for good quality, 27.8 x 18.6 inches or 70.7 x 47.1 cm for very good quality, and 23.2 x 15.5 inches or 58.9 x 39.3 cm for excellent quality prints.
The M6 Mark II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS M6 Mark II has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. The corresponding ISO settings for the Leica S2 are ISO 80 to ISO 1250 (no boost).
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"). 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. The M6 Mark II indeed provides movie recording capabilities, while the S2 does not. The highest resolution format that the M6 Mark II can use is 4K/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the S2 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the M6 Mark II relies on live view and the rear LCD for framing. That said, the M6 Mark II can be equipped with an optional viewfinder – the EVF-DC2. The adjacent table lists some of the other core features of the Canon M6 Mark II and Leica S2 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The M6 Mark II has one, while the S2 does not. While the built-in flash of the M6 Mark II is not very powerful, it can at times be useful as a fill-in light.The M6 Mark II has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the S2 does not have a selfie-screen.
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 M6 Mark II 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 M6 Mark II 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 M6 Mark II writes its imaging data to SDXC cards, while the S2 uses Compact Flash or SDHC cards. The S2 features dual card slots, which can be very useful in case a memory card fails. In contrast, the M6 Mark II only has one slot. The M6 Mark II supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the S2 cannot take advantage of Ultra High Speed SD cards.
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 M6 Mark II and Leica S2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M6 Mark II offers wifi support, while the S2 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Studio photographers will appreciate that the Leica S2 (unlike the M6 Mark II) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The M6 Mark II is a recent model that features in the current product line-up of Canon. In contrast, the S2 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the S2 was succeeded by the Leica S Typ 006. 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.

If the count of relative strengths (bullet points above) is taken as a measure, the M6 Mark II is the clear winner of the match-up (19 : 9 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.

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 M6 Mark II or the S2. 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 why expert reviews are important. 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.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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.
