Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D40 and the Nikon D70? 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

The physical size and weight of the Nikon D40 and the Nikon D70 are illustrated 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 size dimensions are rounded to the nearest millimeter.

Comparison D40 or D70 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D70 is notably larger (33 percent) than the Nikon D40. Moreover, the D70 is markedly heavier (30 percent) than the D40. In this context, it is worth noting that neither the D40 nor the D70 are weather-sealed.

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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Nikon Lens Catalog.

Concerning battery life, the D40 gets 470 shots out of its EN-EL9 battery, while the D70 can take 400 images on a single charge of its EN-EL3 power pack.

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

Any camera decision will naturally be influenced heavily by the price. 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 D40 was launched at a markedly lower price (by 50 percent) than the D70, 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. 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 and have a format factor (sometimes also referred to as "crop factor") of 1.5. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Nikon D40 and Nikon D70 sensor measures

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 6 megapixels. This similarity in sensor specs implies that both the D40 and the D70 have the same pixel density, as well as the same pixel size. It should, however, be noted that the D40 is much more recent (by 2 years and 9 months) than the D70, and its sensor will have benefitted from technological advances during this time.

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 D70 are ISO 200 to ISO 1600 (no boost).

D40 versus D70 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 D40 has a notably higher overall DXO score than the D70 (overall score 6 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.6 bits higher color depth, 0.7 EV in additional dynamic range, and 0.1 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Neither the D40 nor the D70 offer Live View, so that they cannot project the live image that the sensor receives onto the rear screen. Moreover, both cameras are still-image focused and cannot record videos.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The D40 and the D70 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 viewfinders of both cameras offer the same field of view (95%), but the viewfinder of the D40 has a higher magnification than the one of the D70 (0.53x vs 0.50x), 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 D40 and Nikon D70 in connection with corresponding information for a sample of similar cameras.

Both the D40 and the D70 have been discontinued, but can regularly be found used on eBay. The D70 was replaced by the Nikon D70s, while the D40 was followed by the Nikon D40X. 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 is the bottom line? Is there a clear favorite between the Nikon D40 and the Nikon D70? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Nikon D40:

  • Better image quality: Scores markedly higher (6 points) in the DXO overall assessment.
  • More dynamic range: Captures a larger spectrum of light and dark details (0.7 EV of extra DR).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.53x vs 0.50x).
  • Larger screen: Has a bigger rear LCD (2.5" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (230k vs 130k dots).
  • More compact: Is smaller (124x94mm vs 140x111mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 157g or 23 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (470 versus 400) on a single battery charge.
  • Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.0).
  • More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
  • More modern: Reflects 2 years and 9 months of technical progress since the D70 launch.


Advantages of the Nikon D70:

  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (3 vs 2.5 flaps/sec) to capture the decisive moment.
  • More heavily discounted: Has been around for much longer (launched in January 2004).

If the count of relative strengths (bullet points above) is taken as a measure, the D40 is the clear winner of the match-up (11 : 3 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.

D40 11:03 D70

How about other alternatives? Do the specifications of the Nikon D40 and the Nikon D70 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D40 or the D70. 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 where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
