Nikon D40X vs Z50
The Nikon D40X and the Nikon Z50 are two digital cameras that were announced, respectively, in March 2007 and October 2019. The D40X is a DSLR, while the Z50 is a mirrorless interchangeable lens camera. Both cameras are equipped with an APS-C sensor. The D40X has a resolution of 10 megapixels, whereas the Z50 provides 20.7 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 D40X and the Nikon Z50? 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.
An illustration of the physical size and weight of the Nikon D40X and the Nikon Z50 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 width, height and depth dimensions are rounded to the nearest millimeter.
The D40X can be obtained in two different colors (black, silver), while the Z50 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon Z50 is somewhat larger (2 percent) than the Nikon D40X. However, the Z50 is markedly lighter (14 percent) than the D40X. It is noteworthy in this context that the Z50 is splash and dust-proof, while the D40X 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.
The power pack in the Z50 can be charged via the USB port, which can be very convenient when travelling.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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 retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The D40X was launched at a somewhat lower price (by 15 percent) than the Z50, which makes it more attractive for photographers on a tight budget. 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.
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. 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 are more costly to manufacture and tend to 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 Z50 is 1 percent smaller. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, the Z50 uses a more advanced image processing engine (EXPEED 6) than the D40X (EXPEED), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a slightly smaller sensor, the Z50 offers a higher resolution of 20.7 megapixels, compared with 10 MP of the D40X. 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 4.22μm versus 6.11μm for the D40X). However, it should be noted that the Z50 is much more recent (by 12 years and 7 months) than the D40X, 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 Z50 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Nikon Z50 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Z50 for good quality output (200 dots per inch) amounts to 27.8 x 18.6 inches or 70.7 x 47.1 cm, for very good quality (250 dpi) 22.3 x 14.8 inches or 56.6 x 37.7 cm, and for excellent quality (300 dpi) 18.6 x 12.4 inches or 47.1 x 31.4 cm. The corresponding values for the Nikon D40X are 19.4 x 13 inches or 49.2 x 32.9 cm for good quality, 15.5 x 10.4 inches or 39.3 x 26.3 cm for very good quality, and 12.9 x 8.6 inches or 32.8 x 21.9 cm for excellent quality prints.
The Z50 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Nikon D40X has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Nikon Z50 are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 100-204800.
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"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.
| DXO |
|13.||Olympus E-420||Four Thirds||10.0||3648||2736||none||21.5||10.4||527||56|
|14.||Panasonic L10||Four Thirds||10.0||3648||2736||none||21.3||10.8||429||55|
Many modern cameras are not only capable of taking still images, but also of capturing video footage. The Z50 indeed provides for movie recording, while the D40X does not. The highest resolution format that the Z50 can use is 4K/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the Z50 has an electronic viewfinder (2360k dots), while the D40X 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 viewfinder in the Z50 offers a wider field of view (100%) than the one in the D40X (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the Z50 has a higher magnification (0.68x vs 0.53x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Nikon D40X and Nikon Z50 along with similar information for a selection of comparators.
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The Z50 has a touchscreen, while the D40X has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The Z50 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the D40X does not have a selfie-screen.
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 Z50 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 Nikon Z50 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 D40X writes its imaging data to SDHC cards, while the Z50 uses SDXC cards. The Z50 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the D40X cannot take advantage of Ultra High Speed SD cards.
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 D40X and Nikon Z50 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.
| WiFi |
| NFC |
It is notable that the Z50 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D40X does not provide wifi capability.
The Z50 is a recent model that features in the current product line-up of Nikon. In contrast, the D40X has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the D40X was succeeded by the Nikon D60 . 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 Z50 is the clear winner of the contest (24 : 5 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 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.

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 D40X or the Z50 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], 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.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
