Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS M6 Mark II and the Nikon D5? 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 side-by-side display below illustrates the physical size and weight of the Canon M6 Mark II and the Nikon D5. 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 width, height and depth measures 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 Nikon D5 is considerably larger (203 percent) than the Canon M6 Mark II. Moreover, the D5 is substantially heavier (247 percent) than the M6 Mark II. It is noteworthy in this context that the D5 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 Canon LP-E17 battery, while the D5 can take 3780 images on a single charge of its Nikon EN-EL18a power pack. As can be seen in the images above, the D5 has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. 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.

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 M6 Mark II was launched at a markedly lower price (by 87 percent) than the D5, 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 sensor inside a digital camera is one of the key determinants 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. 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 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 Nikon D5 a full frame sensor. The sensor area in the D5 is 154 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 20.7 MP of the Nikon D5. 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 6.44μm for the D5). However, it should be noted that the M6 Mark II is much more recent (by 3 years and 7 months) than the D5, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

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 Nikon D5 are 27.9 x 18.6 inches or 71 x 47.1 cm for good quality, 22.4 x 14.8 inches or 56.8 x 37.7 cm for very good quality, and 18.6 x 12.4 inches or 47.3 x 31.4 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 Nikon D5 are ISO 100 to ISO 102400, with the possibility to increase the ISO range to 50-3280000.

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.

For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. 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 also of capturing video footage. 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/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the D5 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 following table reports on some other key feature differences and similarities of the Canon M6 Mark II, the Nikon D5, and comparable cameras.

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 D5 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, 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 and the Nikon D5 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 D5 uses Compact Flash or XQD cards. The D5 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.

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 Nikon D5 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 D5 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Nikon D5 (unlike the M6 Mark II) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the M6 Mark II and the D5 have been discontinued, but can regularly be found used on ebay. The D5 was replaced by the Nikon D6, while the M6 Mark II does not have a direct successor. Further information on the features and operation of the M6 Mark II and D5 can be found, respectively, in the Canon M6 Mark II Manual (free pdf) or the online Nikon D5 Manual.

Review summary

So how do things add up? Is the Canon M6 Mark II better than the Nikon D5 or vice versa? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Canon EOS M6 Mark II:

• More detail: Offers more megapixels (32.3 vs 20.7MP) with a 25% higher linear resolution.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• 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.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• More compact: Is smaller (120x70mm vs 160x159mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 1007g or 71 percent) and hence easier to carry around.
• Easier travel charging: Can be conveniently charged via its USB port.
• More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• 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 affordable: Was introduced into a lower priced category (87 percent cheaper at launch).
• More modern: Reflects 3 years and 7 months of technical progress since the D5 launch.

Arguments in favor of the Nikon D5:

• Better sound control: Has a headphone port that enables audio monitoring while recording.
• 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.
• Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (2359k vs 1040k dots).
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Gets more shots (3780 versus 305) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More heavily discounted: Has been around for much longer (launched in January 2016).

If the count of relative strengths (bullet points above) is taken as a measure, the M6 Mark II comes out slightly ahead of the D5 (14 : 13 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 M6 Mark II and the Nikon D5 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the M6 Mark II or the D5 perform in practice. 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.

Expert reviews

This is why hands-on reviews by experts 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], 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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
