Nikon D40X vs D850

The Nikon D40X and the Nikon D850 are two digital cameras that were announced, respectively, in March 2007 and July 2017. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (D40X) and a full frame (D850) sensor. The D40X has a resolution of 10 megapixels, whereas the D850 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 D40X and the Nikon D850? 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 D40X vs D850

An illustration of the physical size and weight of the Nikon D40X and the Nikon D850 is provided in the side-by-side display below. 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 dimensions are rounded to the nearest millimeter.

The D40X can be obtained in two different colors (black, silver), while the D850 is only available in black.

Size Nikon D40X vs Nikon D850
Compare D40X versus D850 top
Comparison D40X or D850 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D850 is considerably larger (55 percent) than the Nikon D40X. Moreover, the D850 is substantially heavier (93 percent) than the D40X. It is noteworthy in this context that the D850 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. A larger imaging sensor (as in the D850) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (D40X). You can compare the optics available in the Nikon Lens Catalog.

Concerning battery life, the D40X gets 520 shots out of its EN-EL9 battery, while the D850 can take 1840 images on a single charge of its EN-EL15a power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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 D40X was launched at a markedly lower price (by 78 percent) than the D850, 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 D40X vs D850

The size of the imaging sensor is a crucial determinant 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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon D40X features an APS-C sensor and the Nikon D850 a full frame sensor. The sensor area in the D850 is 130 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.

Technology-wise, the D850 uses a more advanced image processing engine (EXPEED 5) than the D40X (EXPEED), with benefits for noise reduction, color accuracy, and processing speed.

Nikon D40X and Nikon D850 sensor measures

With 45.4MP, the D850 offers a higher resolution than the D40X (10MP), but the D850 has smaller individual pixels (pixel pitch of 4.35μm versus 6.11μm for the D40X). Yet, the D850 is a much more recent model (by 10 years and 4 months) than the D40X, 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 D850 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon D850 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D850 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 D40X are 19.4 x 13 inch or 49.2 x 32.9 cm for good quality, 15.5 x 10.4 inch or 39.3 x 26.3 cm for very good quality, and 12.9 x 8.6 inch or 32.8 x 21.9 cm for excellent quality prints.

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 D850 are ISO 64 to ISO 25600, with the possibility to increase the ISO range to 32-102400.

D40X versus D850 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 D850 offers substantially better image quality than the D40X (overall score 37 points higher). The advantage is based on 4 bits higher color depth, 3.4 EV in additional dynamic range, and 2.4 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The D850 indeed provides for movie recording, while the D40X does not. The highest resolution format that the D850 can use is 4K/30p.

 

Feature comparison: Nikon D40X vs D850

Beyond body and sensor, cameras can and do differ across a range of features. The D40X and the D850 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 viewfinder in the D850 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 D850 has a higher magnification (0.75x vs 0.53x), 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 D40X, the Nikon D850, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The D40X has one, while the D850 does not. While the built-in flash of the D40X is not very powerful, it can at times be useful as a fill-in light.

The Nikon D850 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 D850 uses SDHC or XQD cards. The D850 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D40X only has one slot. The D850 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.

 

Connectivity comparison: Nikon D40X vs D850

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 D850 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D850 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 offer wifi capability.

Studio photographers will appreciate that the Nikon D850 (unlike the D40X) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The D850 is a recent model that features in the current product line-up of Nikon. In contrast, the D40X has been discontinued (but it 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.


Review summary: Nikon D40X vs D850

So how do things add up? Is the Nikon D40X better than the Nikon D850 or vice versa? The listing below highlights the relative strengths of the two models.


Reasons to prefer the Nikon D40X:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More compact: Is smaller (124x94mm vs 146x124mm) and thus needs less room in the bag.

  • Faster burst: Shoots at higher frequency (9 vs 3 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Longer lasting: Gets more shots (1840 versus 520) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-II standard.
  • More modern: Reflects 10 years and 4 months of technical progress since the D40X launch.

If the count of relative strengths (bullet points above) is taken as a measure, the D850 is the clear winner of the contest (28 : 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.

D40X 06:28 D850

How about other alternatives? Do the specifications of the Nikon D40X and the Nikon D850 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the D40X or the D850 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: Nikon D40X vs D850

This is why hands-on reviews by experts 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
