Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS R6 Mark II and the Nikon Z9? 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 R6 Mark II and the Nikon Z9 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon Z9 is considerably larger (65 percent) than the Canon R6 Mark II. Moreover, the Z9 is substantially heavier (100 percent) than the R6 Mark II. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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 R6 Mark II gets 450 shots out of its Canon LP-E6NH battery, while the Z9 can take 740 images on a single charge of its Nikon EN-EL18d power pack. As can be seen in the images above, the Z9 has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the R6 Mark II, Canon provides the BG-R10 vertical grip as an optional accessory (see here on ebay). The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The R6 Mark II was launched at a markedly lower price (by 55 percent) than the Z9, 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.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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.

Both cameras under consideration feature a full frame sensor and have a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the review cameras among the large-sensor cameras that aim for top notch image quality. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

While the two cameras under review share the same sensor size, the Z9 offers a higher resolution of 45.4 megapixels, compared with 24 MP of the R6 Mark II. This megapixels advantage translates into a 38 percent gain in linear resolution. On the other hand, these sensor specs imply that the Z9 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.35μm versus 5.98μm for the R6 Mark II). Moreover, it should be noted, that the R6 Mark II is a somewhat more recent model (by 1 year) than the Z9, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels. Coming back to sensor resolution, it should be mentioned that the Z9 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon Z9 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Z9 for good quality output (200 dots per inch) amounts to 41.3 x 27.5 inches or 104.9 x 69.9 cm, for very good quality (250 dpi) 33 x 22 inches or 83.9 x 55.9 cm, and for excellent quality (300 dpi) 27.5 x 18.3 inches or 69.9 x 46.6 cm. The corresponding values for the Canon R6 Mark II 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 R6 Mark II has a native sensitivity range from ISO 100 to ISO 102400, which can be extended to ISO 100-204800. The corresponding ISO settings for the Nikon Z9 are ISO 64 to ISO 25600, with the possibility to increase the ISO range to 32-102400.

In terms of underlying technology, the R6 Mark II is build around a CMOS sensor, while the Z9 uses a Stacked BSI-CMOS imager. 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 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 also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the Z9 provides a better video resolution than the R6 Mark II. It can shoot movie footage at 8K/30p, while the Canon is limited to 4k/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The R6 Mark II and the Z9 are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 3690k dots. The adjacent table lists some of the other core features of the Canon R6 Mark II and Nikon Z9 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 feature that is present on the Z9, but is missing on the R6 Mark II 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 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 R6 Mark II and the Nikon Z9 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 R6 Mark II writes its imaging data to SDXC cards, while the Z9 uses CFexpress (type B) or XQD cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.

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 R6 Mark II and Nikon Z9 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon Z9 (unlike the R6 Mark II) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Travel and landscape photographers will find it useful that the Z9 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the R6 Mark II and the Z9 are recent models that are part of the current product line-up. The R6 Mark II replaced the earlier Canon R6, while the Z9 does not have a direct predecessor. Further information on the features and operation of the R6 Mark II and Z9 can be found, respectively, in the Canon R6 Mark II Manual (free pdf) or the online Nikon Z9 Manual.

Review summary

So what is the bottom line? Is the Canon R6 Mark II better than the Nikon Z9 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Canon EOS R6 Mark II:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• More compact: Is smaller (138x98mm vs 149x150mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 670g or 50 percent) and hence easier to carry around.
• More affordable: Was introduced into a lower priced category (55 percent cheaper at launch).
• More modern: Is somewhat more recent (announced 1 year after the Z9).

Advantages of the Nikon Z9:

• More detail: Has more megapixels (45.4 vs 24MP), which boosts linear resolution by 38%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better video: Provides higher definition movie capture (8K/30p vs 4k/60p).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.80x vs 0.76x).
• 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 (2089k vs 1620k dots).
• Faster shutter: Has higher mechanical shutter speed (1/32000s vs 1/8000s) to freeze action.
• Faster burst: Shoots at higher frequency (30 vs 12 flaps/sec) to capture the decisive moment.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Gets more shots (740 versus 450) out of a single battery charge.
• Easier geotagging: Features an internal GPS sensor to log localization data.
• More solid recording: Has a full-sized HDMI port for a sturdy connection to an external recorder.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• More heavily discounted: Has been on the market for longer (launched in October 2021).

If the count of relative strengths (bullet points above) is taken as a measure, the Z9 is the clear winner of the contest (15 : 6 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 R6 Mark II and the Nikon Z9 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the R6 Mark II or the Z9 perform in practice. 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 why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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 assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
