Nikon D4 vs D40X

The Nikon D4 and the Nikon D40X are two digital cameras that were officially introduced, respectively, in January 2012 and March 2007. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (D4) and an APS-C (D40X) sensor. The D4 has a resolution of 16.2 megapixels, whereas the D40X provides 10 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 D4 and the Nikon D40X? 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 Nikon D4 and the Nikon D40X is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.

The D40X can be obtained in two different colors (black, silver), while the D4 is only available in black.

Compare D4 versus D40X top
Comparison D4 or D40X rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D40X is considerably smaller (54 percent) than the Nikon D4. Moreover, the D40X is substantially lighter (61 percent) than the D4. It is worth mentioning in this context that the D4 is splash and dust resistant, 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 D4) 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 D4 gets 2600 shots out of its EN-EL18 battery, while the D40X can take 520 images on a single charge of its EN-EL9 power pack. As can be seen in the images above, the D4 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 D40X, there are third party battery grips available as optional accessories (see here on eBay).

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The D40X was launched at a markedly lower price (by 88 percent) than the D4, 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

The size of the sensor inside a digital camera is one of the key determinants 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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Nikon D4 features a full frame sensor and the Nikon D40X an APS-C sensor. The sensor area in the D40X is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

In terms of chip-set technology, the D4 uses a more advanced image processing engine (EXPEED 3) than the D40X (EXPEED), with benefits for noise reduction, color accuracy, and processing speed.

Nikon D4 and Nikon D40X sensor measures

With 16.2MP, the D4 offers a higher resolution than the D40X (10MP), but the D4 nevertheless has larger individual pixels (pixel pitch of 7.29μm versus 6.11μm for the D40X) due to its larger sensor. Moreover, the D4 is a much more recent model (by 4 years and 10 months) than the D40X, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Nikon D4 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D4 for good quality output (200 dots per inch) amounts to 24.6 x 16.4 inches or 62.6 x 41.7 cm, for very good quality (250 dpi) 19.7 x 13.1 inches or 50.1 x 33.3 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.7 x 27.8 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 Nikon D4 has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 50-204800. The corresponding ISO settings for the Nikon D40X are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.

D4 versus D40X 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 review, the D4 provides substantially higher image quality than the D40X, with an overall score that is 26 points higher. This advantage is based on 2.3 bits higher color depth, 1.7 EV in additional dynamic range, and 2.5 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 cannot only take still pictures, but also record videos. The D4 indeed provides movie recording capabilities, while the D40X does not. The highest resolution format that the D4 can use is 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The D4 and the D40X 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 D4 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 D4 has a higher magnification (0.70x vs 0.53x), 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 Nikon D4 and Nikon D40X in connection with corresponding information for a sample of similar cameras.

One feature that is present on the D4, but is missing on the D40X is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The Nikon D4 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 D4 writes its imaging data to Compact Flash or XQD cards, while the D40X uses SDHC cards. The D4 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D40X 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 Nikon D4 and Nikon D40X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon D4 (unlike the D40X) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D4 and the D40X have been discontinued, but can regularly be found used on eBay. The D40X was replaced by the Nikon D60 , while the D4 was followed by the Nikon D4S. 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 D4 or the Nikon D40X – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.


Reasons to prefer the Nikon D4:

  • More detail: Offers more megapixels (16.2 vs 10MP) with a 27% higher linear resolution.
  • Better image quality: Scores substantially higher (26 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (2.3 bits more color depth).
  • More dynamic range: Captures a larger spectrum of light and dark details (1.7 EV of extra DR).
  • Better low-light sensitivity: Requires less light for good images (2.5 stops ISO advantage).
  • Better jpgs: Has a more modern image processing engine (EXPEED 3 vs EXPEED).
  • Broader imaging potential: Can record not only still images but also 1080/30p movies.
  • More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.53x).
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • 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 (921k vs 230k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (11 vs 3 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Longer lasting: Can take more shots (2600 versus 520) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • 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.
  • More modern: Reflects 4 years and 10 months of technical progress since the D40X launch.


Advantages of the Nikon D40X:

  • More compact: Is smaller (124x94mm vs 160x157mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 818g or 61 percent) and is thus easier to take along.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (88 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in March 2007).

If the count of individual advantages (bullet points above) is taken as a guide, the D4 is the clear winner of the match-up (21 : 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 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.

D4 21:05 D40X

How about other alternatives? Do the specifications of the Nikon D4 and the Nikon D40X 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 D4 or the D40X 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 adjacent summary-table relays the overall verdicts of several of the most popular camera 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.

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

The review scores listed above should be treated 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. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
