Canon M6 Mark II vs Sony A7C
The Canon EOS M6 Mark II and the Sony Alpha A7C are two digital cameras that were officially introduced, respectively, in August 2019 and September 2020. Both the M6 Mark II and the A7C are mirrorless interchangeable lens cameras that are based on an APS-C (M6 Mark II) and a full frame (A7C) sensor. The Canon has a resolution of 32.3 megapixels, whereas the Sony provides 24 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 M6 Mark II and the Sony Alpha A7C? 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.
An illustration of the physical size and weight of the Canon M6 Mark II and the Sony A7C is provided 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 size dimensions are rounded to the nearest millimeter.
The A7C can be obtained in two different colors (black, silver), while the M6 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 Sony A7C is somewhat larger (5 percent) than the Canon M6 Mark II. Moreover, the A7C is markedly heavier (25 percent) than the M6 Mark II. It is noteworthy in this context that the A7C 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.
Concerning battery life, the M6 Mark II gets 305 shots out of its LP-E17 battery, while the A7C can take 740 images on a single charge of its NP-FZ100 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

Any camera decision will obviously take relative prices into account. 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 M6 Mark II was launched at a markedly lower price (by 53 percent) than the A7C, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 sensor inside a digital camera is one of the key determinants 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. 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 M6 Mark II features an APS-C sensor and the Sony A7C a full frame sensor. The sensor area in the A7C is 151 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.
Despite having a smaller sensor, the Canon M6 Mark II offers a higher resolution of 32.3 megapixels, compared with 24 MP of the Sony A7C. 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 5.94μm for the A7C). Moreover, it should be noted that the A7C is a somewhat more recent model (by 1 year) than the M6 Mark II, and its sensor might 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 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 Sony A7C are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.
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 Sony Alpha A7C are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.
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 cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (4K/30p).
Beyond body and sensor, cameras can and do differ across a range of features. For example, the A7C 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 Sony A7C 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 A7C 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.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
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 Sony A7C 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.
The M6 Mark II writes its imaging data to SDXC cards, while the A7C uses SDXC or Memory Stick PRO Duo cards. Both cameras support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s.
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 Sony Alpha A7C and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7C has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The M6 Mark II lacks such a headphone port.
Both the M6 Mark II and the A7C are recent models that are part of the current product line-up. The M6 Mark II replaced the earlier Canon M6, while the A7C does not have a direct predecessor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Sony websites.
So what conclusions can be drawn? Is the Canon M6 Mark II better than the Sony A7C or vice versa? The listing below highlights the relative strengths of the two models.

If the count of relative strengths (bullet points above) is taken as a measure, the A7C is the clear winner of the contest (13 : 7 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 A7C. 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 why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], 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.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
