Nikon D2X vs Z7

The Nikon D2X and the Nikon Z7 are two digital cameras that were officially introduced, respectively, in September 2004 and August 2018. The D2X is a DSLR, while the Z7 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D2X) and a full frame (Z7) sensor. The D2X has a resolution of 12.2 megapixels, whereas the Z7 provides 45.4 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 Nikon D2X and the Nikon Z7? 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 Nikon D2X and the Nikon Z7. 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.

Size Nikon D2X vs Nikon Z7
Compare D2X versus Z7 top
Comparison D2X or Z7 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon Z7 is considerably smaller (43 percent) than the Nikon D2X. Moreover, the Z7 is substantially lighter (46 percent) than the D2X. 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 D2X gets 3800 shots out of its EN-EL4a battery, while the Z7 can take 330 images on a single charge of its EN-EL15b power pack. As can be seen in the images above, the D2X 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 Z7, Nikon provides the MB-N10 vertical grip as an optional accessory (see here on eBay). The power pack in the Z7 can be charged via the USB port, which can be very convenient when travelling.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. 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 Z7 was launched at a markedly lower price (by 32 percent) than the D2X, 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 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon D2X features an APS-C sensor and the Nikon Z7 a full frame sensor. The sensor area in the Z7 is 131 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Nikon D2X and Nikon Z7 sensor measures

With 45.4MP, the Z7 offers a higher resolution than the D2X (12.2MP), but the Z7 has smaller individual pixels (pixel pitch of 4.35μm versus 5.52μm for the D2X). Yet, the Z7 is a much more recent model (by 13 years and 11 months) than the D2X, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the Z7 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon Z7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Z7 for good quality output (200 dots per inch) amounts to 41.3 x 27.5 inch or 104.9 x 69.9 cm, for very good quality (250 dpi) 33 x 22 inch or 83.9 x 55.9 cm, and for excellent quality (300 dpi) 27.5 x 18.3 inch or 69.9 x 46.6 cm. The corresponding values for the Nikon D2X are 21.4 x 14.2 inch or 54.5 x 36.2 cm for good quality, 17.2 x 11.4 inch or 43.6 x 28.9 cm for very good quality, and 14.3 x 9.5 inch or 36.3 x 24.1 cm for excellent quality prints.

The Z7 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Nikon D2X has a native sensitivity range from ISO 100 to ISO 800, which can be extended to ISO 100-3200. The corresponding ISO settings for the Nikon Z7 are ISO 64 to ISO 25600, with the possibility to increase the ISO range to 32-102400.

D2X versus Z7 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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. Of the two cameras under consideration, the Z7 offers substantially better image quality than the D2X (overall score 40 points higher). The advantage is based on 4.2 bits higher color depth, 3.7 EV in additional dynamic range, and 2.5 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 Z7 indeed provides for movie recording, while the D2X does not. The highest resolution format that the Z7 can use is 4K/30p.

 

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the Z7 has an electronic viewfinder (3690k dots), while the D2X has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the Z7 has a higher magnification than the one of the D2X (0.80x vs 0.57x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Nikon D2X, the Nikon Z7, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The Z7 has a touchscreen, while the D2X has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Nikon Z7 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 D2X writes its imaging data to Compact Flash cards, while the Z7 uses XQD cards.

 

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 Nikon D2X and Nikon Z7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Z7 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D2X does not offer wifi capability.

Studio photographers will appreciate that the Nikon D2X (unlike the Z7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The Z7 is a recent model that features in the current product line-up of Nikon. In contrast, the D2X has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the D2X was succeeded by the Nikon D2Xs. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon website.


Review summary

So what conclusions can be drawn? Which of the two cameras – the Nikon D2X or the Nikon Z7 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Nikon D2X:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Longer lasting: Can take more shots (3800 versus 330) on a single battery charge.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More heavily discounted: Has been available for much longer (launched in September 2004).


Reasons to prefer the Nikon Z7:

  • More detail: Has more megapixels (45.4 vs 12.2MP), which boosts linear resolution by 93%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores substantially higher (40 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (4.2 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (3.7 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (2.5 stops ISO advantage).
  • Broader imaging potential: Can capture not only stills but also 4K/30p video.
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.80x vs 0.57x).
  • Larger screen: Has a bigger rear LCD (3.2" vs 2.5") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (2100k vs 235k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (9 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 (134x101mm vs 158x150mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 577g or 46 percent) and is thus easier to take along.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
  • 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 (32 percent cheaper at launch).
  • More modern: Reflects 13 years and 11 months of technical progress since the D2X launch.

If the count of individual advantages (bullet points above) is taken as a guide, the Z7 is the clear winner of the contest (25 : 6 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.

D2X 06:25 Z7

How about other alternatives? Do the specifications of the Nikon D2X and the Nikon Z7 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the D2X or the Z7 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 expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

The above review scores should be interpreted with care, 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
