Nikon D3X vs Z7
The Nikon D3X and the Nikon Z7 are two digital cameras that were revealed to the public, respectively, in December 2008 and August 2018. The D3X is a DSLR, while the Z7 is a mirrorless interchangeable lens camera. Both cameras are equipped with a full frame sensor. The D3X has a resolution of 24.4 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 D3X 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: Nikon D3X vs Z7
The side-by-side display below illustrates the physical size and weight of the Nikon D3X and the Nikon Z7. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. 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 Z7 is considerably smaller (46 percent) than the Nikon D3X. Moreover, the Z7 is substantially lighter (46 percent) than the D3X. 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 D3X gets 4400 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 D3X 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.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Z7 was launched at a markedly lower price (by 58 percent) than the D3X, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison: Nikon D3X vs Z7
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the 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 a full frame sensor, but their sensors differ slightly in size. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, the Z7 uses a more advanced image processing engine (EXPEED 6) than the D3X (EXPEED), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a slightly smaller sensor, the Z7 offers a higher resolution of 45.4 megapixels, compared with 24.4 MP of the D3X. 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 4.35μm versus 5.94μm for the D3X). However, it should be noted that the Z7 is much more recent (by 9 years and 8 months) than the D3X, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. 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 D3X are 30.2 x 20.2 inch or 76.8 x 51.2 cm for good quality, 24.2 x 16.1 inch or 61.4 x 41 cm for very good quality, and 20.2 x 13.4 inch or 51.2 x 34.1 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 D3X has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 50-6400. 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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 consideration, the Z7 offers substantially better image quality than the D3X (overall score 11 points higher). The advantage is based on 1.6 bits higher color depth, 0.9 EV in additional dynamic range, and 0.4 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 D3X does not. The highest resolution format that the Z7 can use is 4K/30p.
Feature comparison: Nikon D3X vs Z7
Apart from body and sensor, cameras can and do differ across a range of features. For example, the Z7 has an electronic viewfinder (3690k dots), while the D3X 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 D3X (0.80x vs 0.70x), 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 D3X, 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 D3X has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
The Nikon D3X and the Nikon Z7 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 D3X writes its imaging data to Compact Flash cards, while the Z7 uses XQD cards. The D3X features dual card slots, which can be very useful in case a memory card fails. In contrast, the Z7 only has one slot.
Connectivity comparison: Nikon D3X vs Z7
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 D3X 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 D3X does not offer wifi capability.
Studio photographers will appreciate that the Nikon D3X (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 D3X has been discontinued (but it can be found pre-owned on eBay). There has not been a direct replacement model for the D3X from Nikon. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon website.

If the count of relative strengths (bullet points above) is taken as a measure, the Z7 is the clear winner of the contest (25 : 7 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 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 Nikon D3X 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the D3X and the Z7 in practical situations. 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: Nikon D3X vs Z7
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 (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.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
