Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 7D Mark II and the Nikon D2Xs? 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 7D II and the Nikon D2Xs 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 D2Xs is notably larger (42 percent) than the Canon 7D II. Moreover, the D2Xs is substantially heavier (38 percent) than the 7D 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. Yet, since both cameras are based around an APS-C sensor, their respective lenses will tend to have similar dimensions and heft. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (7D Mark II) and the Nikon Lens Catalog (D2Xs).

Concerning battery life, the 7D Mark II gets 670 shots out of its Canon LP-E6N battery, while the D2Xs can take 3800 images on a single charge of its Nikon EN-EL4a power pack. As can be seen in the images above, the D2Xs 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 7D Mark II, Canon provides the BG-E16 vertical grip as an optional accessory (see here on ebay).

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 7D Mark II was launched at a markedly lower price (by 62 percent) than the D2Xs, 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 size of the imaging sensor is a crucial determinant 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. 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 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 D2Xs is 11 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (7D 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 7D II offers a higher resolution of 20 megapixels, compared with 12.2 MP of the Nikon D2Xs. 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 4.10μm versus 5.52μm for the D2Xs). However, it should be noted that the 7D Mark II is much more recent (by 8 years and 3 months) than the D2Xs, 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 7D II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 7D Mark II for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Nikon D2Xs are 21.4 x 14.2 inches or 54.5 x 36.2 cm for good quality, 17.2 x 11.4 inches or 43.6 x 28.9 cm for very good quality, and 14.3 x 9.5 inches or 36.3 x 24.1 cm for excellent quality prints.

The 7D Mark II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS 7D Mark II has a native sensitivity range from ISO 100 to ISO 16000, which can be extended to ISO 100-51200. The corresponding ISO settings for the Nikon D2Xs are ISO 100 to ISO 800, with the possibility to increase the ISO range to 800-3200.

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 determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under review, the 7D Mark II provides substantially higher image quality than the D2Xs, with an overall score that is 11 points higher. This advantage is based on 0.2 bits higher color depth, 0.9 EV in additional dynamic range, and 1.1 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 cannot only take still pictures, but also record videos. The 7D Mark II indeed provides movie recording capabilities, while the D2Xs does not. The highest resolution format that the 7D Mark II can use is 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 7D Mark II and the D2Xs are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the 7D Mark II has a higher magnification than the one of the D2Xs (0.63x vs 0.57x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 7D II and Nikon D2Xs in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The 7D Mark II has one, while the D2Xs does not. While the built-in flash of the 7D Mark II is not very powerful, it can at times be useful as a fill-in light.

The Canon 7D 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.

The 7D Mark II writes its imaging data to Compact Flash or SDXC cards, while the D2Xs uses Compact Flash cards. The 7D Mark II features dual card slots, which can be very useful in case a memory card fails. In contrast, the D2Xs 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 7D Mark II and Nikon D2Xs and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Travel and landscape photographers will find it useful that the 7D Mark II has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the 7D Mark II and the D2Xs have been discontinued, but can regularly be found used on ebay. The D2Xs was replaced by the Nikon D3X, while the 7D Mark II does not have a direct successor. Further information on the features and operation of the 7D Mark II and D2Xs can be found, respectively, in the Canon 7D II Manual (free pdf) or the online Nikon D2Xs Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon 7D II and the Nikon D2Xs? Which camera is better? The listing below highlights the relative strengths of the two models.

Advantages of the Canon EOS 7D Mark II:

• More detail: Offers more megapixels (20 vs 12.2MP) with a 28% higher linear resolution.
• Better image quality: Scores substantially higher (11 points) in the DXO overall assessment.
• More dynamic range: Captures a larger spectrum of light and dark details (0.9 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (1.1 stops ISO advantage).
• Broader imaging potential: Can record not only still images but also 1080/60p movies.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.63x vs 0.57x).
• Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
• Faster burst: Shoots at higher frequency (10 vs 5 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More compact: Is smaller (149x112mm vs 158x150mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 342g or 27 percent) and hence easier to carry around.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• Easier geotagging: Features an internal GPS sensor to log localization data.
• Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More affordable: Was introduced into a lower priced category (62 percent cheaper at launch).
• More modern: Reflects 8 years and 3 months of technical progress since the D2Xs launch.

Reasons to prefer the Nikon D2Xs:

• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Gets more shots (3800 versus 670) out of a single battery charge.
• More heavily discounted: Has been around for much longer (launched in June 2006).

If the count of individual advantages (bullet points above) is taken as a guide, the 7D Mark II is the clear winner of the match-up (19 : 3 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 7D II and the Nikon D2Xs place the cameras among the top in their class? Find out in the latest Best DSLR 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 7D Mark II or the D2Xs 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 where reviews by experts come in. 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. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
