Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS M6 Mark II and the Leica CL (Typ 7323)? 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 M6 Mark II and the Leica CL 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 Leica CL is notably larger (22 percent) than the Canon M6 Mark II. However, the CL is slightly lighter (1 percent) than the M6 Mark II. In this context, it is worth noting that neither the M6 Mark II nor the CL are weather-sealed.

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 M6 Mark II gets 305 shots out of its Canon LP-E17 battery, while the CL can take 220 images on a single charge of its Leica BP-DC12 power pack. 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.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The M6 Mark II was launched at a markedly lower price (by 70 percent) than the CL, 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 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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the CL is 10 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (M6 Mark II) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Despite having a smaller sensor, the Canon M6 Mark II offers a higher resolution of 32.3 megapixels, compared with 24.1 MP of the Leica CL. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.23μm versus 3.92μm for the CL). However, it should be noted that the M6 Mark II is a somewhat more recent model (by 1 year and 9 months) than the CL, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage. Coming back to sensor resolution, it should be mentioned that the CL has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon M6 Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M6 Mark II for good quality output (200 dots per inch) amounts to 34.8 x 23.2 inches or 88.4 x 58.9 cm, for very good quality (250 dpi) 27.8 x 18.6 inches or 70.7 x 47.1 cm, and for excellent quality (300 dpi) 23.2 x 15.5 inches or 58.9 x 39.3 cm. The corresponding values for the Leica CL are 30.1 x 20.1 inches or 76.4 x 51 cm for good quality, 24.1 x 16.1 inches or 61.1 x 40.8 cm for very good quality, and 20 x 13.4 inches or 50.9 x 34 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 CL (Typ 7323) are ISO 100 to ISO 50000 (no boost).

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"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Note: DXO values in italics represent estimates based on sensor size and age.

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, and both provide the same movie specifications (4K/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the CL has an electronic viewfinder (2360k dots), which can be very helpful 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 CL along with similar information for a selection of comparators.

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

One difference between the cameras concerns the presence of an on-board flash. The M6 Mark II has one, while the CL 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 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, both cameras under consideration feature an 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 and the Leica CL both have 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.

Concerning the storage of imaging data, both the M6 Mark II and the CL write their files to SDXC cards. Both cameras support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s.

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 M6 Mark II and Leica CL (Typ 7323) 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 has a microphone port, which is missing on the CL. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Both the M6 Mark II and the CL have been discontinued, but can regularly be found used on ebay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from Canon and Leica. Further information on the features and operation of the M6 Mark II and CL can be found, respectively, in the Canon M6 Mark II Manual (free pdf) or the online Leica CL Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Canon M6 Mark II or the Leica CL – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Canon EOS M6 Mark II:

• More detail: Offers more megapixels (32.3 vs 24.1MP) with a 16% higher linear resolution.
• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (14 vs 10 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (120x70mm vs 131x78mm) and thus needs less room in the bag.
• Longer lasting: Can take more shots (305 versus 220) on a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More affordable: Was introduced into a lower priced category (70 percent cheaper at launch).
• More modern: Is somewhat more recent (announced 1 year and 9 months after the CL).

Advantages of the Leica CL (Typ 7323):

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Easier setting verification: Features a control panel on top to check shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More heavily discounted: Has been on the market for longer (launched in November 2017).

If the number of relative strengths (bullet points above) is taken as a guide, the M6 Mark II is the clear winner of the match-up (14 : 6 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 Canon M6 Mark II and the Leica CL place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing 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 M6 Mark II and the CL 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.

Expert reviews

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 (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. A score, therefore, has to be seen in close connection to the price and market introduction time 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
