Nikon D40 vs D5

The Nikon D40 and the Nikon D5 are two digital cameras that were announced, respectively, in November 2006 and January 2016. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (D40) and a full frame (D5) sensor. The D40 has a resolution of 6 megapixels, whereas the D5 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 D40 and the Nikon D5? 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 D40 and the Nikon D5 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D5 is considerably larger (118 percent) than the Nikon D40. Moreover, the D5 is substantially heavier (171 percent) than the D40. It is noteworthy in this context that the D5 is splash and dust-proof, while the D40 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 D5) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (D40). You can compare the optics available in the Nikon Lens Catalog.

Concerning battery life, the D40 gets 470 shots out of its Nikon EN-EL9 battery, while the D5 can take 3780 images on a single charge of its Nikon EN-EL18a power pack. As can be seen in the images above, the D5 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 D40, 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. 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 D40 was launched at a markedly lower price (by 92 percent) than the D5, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon D40 features an APS-C sensor and the Nikon D5 a full frame sensor. The sensor area in the D5 is 132 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.

With 20.7MP, the D5 offers a higher resolution than the D40 (6MP), but the D5 has smaller individual pixels (pixel pitch of 6.44μm versus 7.85μm for the D40). Yet, the D5 is a much more recent model (by 9 years and 1 month) than the D40, 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 D5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D5 for good quality output (200 dots per inch) amounts to 27.9 x 18.6 inches or 71 x 47.1 cm, for very good quality (250 dpi) 22.4 x 14.8 inches or 56.8 x 37.7 cm, and for excellent quality (300 dpi) 18.6 x 12.4 inches or 47.3 x 31.4 cm. The corresponding values for the Nikon D40 are 15 x 10 inches or 38.2 x 25.4 cm for good quality, 12 x 8 inches or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inches or 25.5 x 16.9 cm for excellent quality prints.

The Nikon D40 has a native sensitivity range from ISO 200 to ISO 1600, which can be extended to ISO 200-3200. The corresponding ISO settings for the Nikon D5 are ISO 100 to ISO 102400, with the possibility to increase the ISO range to 50-3280000.

In terms of underlying technology, the D40 is build around a CCD sensor, while the D5 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.

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 D5 offers substantially better image quality than the D40 (overall score 32 points higher). The advantage is based on 4.1 bits higher color depth, 1.3 EV in additional dynamic range, and 2.1 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.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The D5 indeed provides for movie recording, while the D40 does not. The highest resolution format that the D5 can use is 4K/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The D40 and the D5 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 D5 offers a wider field of view (100%) than the one in the D40 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the D5 has a higher magnification (0.72x 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 D40 and Nikon D5 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The D40 has one, while the D5 does not. While the built-in flash of the D40 is not very powerful, it can at times be useful as a fill-in light.

The Nikon D5 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 D40 writes its imaging data to SDHC cards, while the D5 uses Compact Flash or XQD cards. The D5 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D40 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 D40 and Nikon D5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon D5 (unlike the D40) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D40 and the D5 have been discontinued, but can regularly be found used on ebay. The D40 was replaced by the Nikon D40X, while the D5 was followed by the Nikon D6. Further information on the features and operation of the D40 and D5 can be found, respectively, in the Nikon D40 Manual (free pdf) or the online Nikon D5 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Nikon D40 and the Nikon D5? Which camera is better? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Nikon D40:

• More compact: Is smaller (124x94mm vs 160x159mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 893g or 63 percent) and hence easier to carry around.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More affordable: Was introduced into a lower priced category (92 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in November 2006).

Advantages of the Nikon D5:

• More detail: Has more megapixels (20.7 vs 6MP), which boosts linear resolution by 86%.
• Better image quality: Scores substantially higher (32 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (4.1 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (1.3 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (2.1 stops ISO advantage).
• Broader imaging potential: Can capture not only stills but also 4K/30p 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 (0.72x 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 (2359k vs 230k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (14 vs 2.5 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: Gets more shots (3780 versus 470) 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).
• 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 9 years and 1 month of technical progress since the D40 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the D5 is the clear winner of the contest (22 : 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.

How about other alternatives? Do the specifications of the Nikon D40 and the Nikon D5 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 incomplete and does no justice, for example, to the way the D40 or the D5 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.

Expert reviews

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], 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.

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

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.
