Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS M and the Canon EOS 6D 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 physical size and weight of the Canon M and the Canon 6D Mark II 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 measures are rounded to the nearest millimeter.

The Canon M can be obtained in two different colors (black, white), while the 6D 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 6D Mark II is considerably larger (122 percent) than the Canon M. Moreover, the 6D Mark II is substantially heavier (157 percent) than the Canon M. It is noteworthy in this context that the 6D Mark II is splash and dust-proof, while the Canon M 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.

Concerning battery life, the Canon M gets 230 shots out of its Canon LP-E12 battery, while the 6D Mark II can take 1200 images on a single charge of its Canon LP-E6N power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The Canon M was launched at a markedly lower price (by 70 percent) than the 6D 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.

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 Canon M features an APS-C sensor and the Canon 6D Mark II a full frame sensor. The sensor area in the 6D Mark II is 160 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the 6D Mark II uses a more advanced image processing engine (DIGIC 7) than the Canon M (DIGIC V), with benefits for noise reduction, color accuracy, and processing speed.

With 26MP, the 6D Mark II offers a higher resolution than the Canon M (17.9MP), but the 6D Mark II nevertheless has larger individual pixels (pixel pitch of 5.76μm versus 4.31μm for the Canon M) due to its larger sensor. Moreover, the 6D Mark II is a much more recent model (by 4 years and 11 months) than the Canon M, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Canon 6D Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 6D Mark II for good quality output (200 dots per inch) amounts to 31.2 x 20.8 inches or 79.2 x 52.8 cm, for very good quality (250 dpi) 25 x 16.6 inches or 63.4 x 42.3 cm, and for excellent quality (300 dpi) 20.8 x 13.9 inches or 52.8 x 35.2 cm. The corresponding values for the Canon M 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 M has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Canon EOS 6D Mark II are ISO 100 to ISO 40000, with the possibility to increase the ISO range to 50-102400.

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 6D Mark II offers substantially better image quality than the Canon M (overall score 20 points higher). The advantage is based on 2.3 bits higher color depth, 0.7 EV in additional dynamic range, and 1.8 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 are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 6D Mark II provides a faster frame rate than the Canon M. It can shoot movie footage at 1080/60p, while the Canon M is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 6D Mark II has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the Canon M relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon M, the Canon 6D Mark II, and comparable cameras.

One feature that is present on the 6D Mark II, but is missing on the Canon M 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 Canon 6D 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.

Concerning the storage of imaging data, both the Canon M and the 6D Mark II write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 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 M and Canon EOS 6D Mark II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 6D Mark II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the Canon M does not provide wifi capability.

Travel and landscape photographers will find it useful that the 6D Mark II has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

The 6D Mark II is a recent model that features in the current product line-up of Canon. In contrast, the Canon M has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the Canon M was succeeded by the Canon EOS M3. Further information on the features and operation of the Canon M and 6D Mark II can be found, respectively, in the Canon M Manual (free pdf) or the online Canon 6D Mark II Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon M and the Canon 6D Mark II? 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 M:

• More compact: Is smaller (109x66mm vs 144x111mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 467g or 61 percent) and hence easier to carry around.
• More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
• More affordable: Was introduced into a lower priced category (70 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in July 2012).

Arguments in favor of the Canon EOS 6D Mark II:

• More detail: Has more megapixels (26 vs 17.9MP), which boosts linear resolution by 20%.
• Better image quality: Scores substantially higher (20 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (2.3 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (0.7 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (1.8 stops ISO advantage).
• Better jpgs: Has a more modern image processing engine (DIGIC 7 vs DIGIC V).
• Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Easier setting verification: Features a control panel on top to check shooting parameters.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (6.5 vs 4.3 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Longer lasting: Gets more shots (1200 versus 230) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Easier geotagging: Features an internal GPS sensor to log localization data.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More modern: Reflects 4 years and 11 months of technical progress since the Canon M launch.

If the count of individual advantages (bullet points above) is taken as a guide, the 6D Mark II is the clear winner of the contest (20 : 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 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 M and the Canon 6D Mark II place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the Canon M or the 6D Mark II. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why hands-on reviews by experts are important. 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.

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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
