Nikon D40X vs D750

The Nikon D40X and the Nikon D750 are two digital cameras that were announced, respectively, in March 2007 and September 2014. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (D40X) and a full frame (D750) sensor. The D40X has a resolution of 10 megapixels, whereas the D750 provides 24.2 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 D750? 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 D40X and the Nikon D750 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 D750 is only available in black.

Compare D40X versus D750 top
Comparison D40X or D750 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D750 is notably larger (37 percent) than the Nikon D40X. Moreover, the D750 is substantially heavier (44 percent) than the D40X. It is noteworthy in this context that the D750 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 D750) 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 D750 can take 1230 images on a single charge of its EN-EL15 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

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

The price is, of course, an important factor in any camera decision. 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 markedly lower price (by 68 percent) than the D750, 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 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 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 D750 a full frame sensor. The sensor area in the D750 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.

Technology-wise, the D750 uses a more advanced image processing engine (EXPEED 4) than the D40X (EXPEED), with benefits for noise reduction, color accuracy, and processing speed.

Nikon D40X and Nikon D750 sensor measures

With 24.2MP, the D750 offers a higher resolution than the D40X (10MP), but the D750 has smaller individual pixels (pixel pitch of 5.97μm versus 6.11μm for the D40X). Yet, the D750 is a much more recent model (by 7 years and 6 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.

The resolution advantage of the Nikon D750 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D750 for good quality output (200 dots per inch) amounts to 30.1 x 20.1 inches or 76.4 x 51 cm, for very good quality (250 dpi) 24.1 x 16.1 inches or 61.1 x 40.8 cm, and for excellent quality (300 dpi) 20.1 x 13.4 inches or 50.9 x 34 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 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 D750 are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 50-51200.

In terms of underlying technology, the D40X is build around a CCD sensor, while the D750 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

D40X versus D750 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 D750 offers substantially better image quality than the D40X (overall score 30 points higher). The advantage is based on 2.4 bits higher color depth, 3.1 EV in additional dynamic range, and 2.5 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Note: DXO values in italics represent estimates based on sensor size and age.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The D750 indeed provides for movie recording, while the D40X does not. The highest resolution format that the D750 can use is 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The D40X and the D750 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 D750 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 D750 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 D40X and Nikon D750 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the D750, 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 D750 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 D750 uses SDXC cards. The D750 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D40X only has one slot. The D750 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D40X cannot take advantage of Ultra High Speed SD 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 D40X and Nikon D750 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D750 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.

Studio photographers will appreciate that the Nikon D750 (unlike the D40X) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D40X and the D750 have been discontinued, but can regularly be found used on ebay. The D40X was replaced by the Nikon D60 , while the D750 was followed by the Nikon D780. Further information on the features and operation of the D40X and D750 can be found, respectively, in the Nikon D40X Manual (free pdf) or the online Nikon D750 Manual.

Review summary

So how do things add up? Is the Nikon D40X better than the Nikon D750 or vice versa? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Nikon D40X:

  • More compact: Is smaller (124x94mm vs 141x113mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 228g or 30 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (68 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in March 2007).


Reasons to prefer the Nikon D750:

  • More detail: Has more megapixels (24.2 vs 10MP), which boosts linear resolution by 55%.
  • Better image quality: Scores substantially higher (30 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.4 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (3.1 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (2.5 stops ISO advantage).
  • Better jpgs: Has a more modern image processing engine (EXPEED 4 vs EXPEED).
  • Broader imaging potential: Can capture not only stills but also 1080/60p video.
  • 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 a control panel on top to check 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 (1229k vs 230k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster burst: Shoots at higher frequency (6 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 (1230 versus 520) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • 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-I standard.
  • More modern: Reflects 7 years and 6 months of technical progress since the D40X launch.

If the count of relative strengths (bullet points above) is taken as a measure, the D750 is the clear winner of the contest (22 : 4 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.

D40X 04:22 D750

How about other alternatives? Do the specifications of the Nikon D40X and the Nikon D750 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D40X or the D750. 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

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 (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], 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.

Care should be taken when interpreting the review scores above, 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 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.
