Nikon D70s vs D40
The Nikon D70s and the Nikon D40 are two digital cameras that were officially introduced, respectively, in April 2005 and November 2006. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. Both cameras offer a resolution of 6 megapixels.
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 D70s and the Nikon D40? 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 D70s and the Nikon D40 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 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 D40 is notably smaller (25 percent) than the Nikon D70s. Moreover, the D40 is markedly lighter (23 percent) than the D70s. In this context, it is worth noting that neither the D70s nor the D40 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 D70s gets 500 shots out of its Nikon EN-EL3a battery, while the D40 can take 470 images on a single charge of its Nikon EN-EL9 power pack.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The D40 was launched at a markedly lower price (by 44 percent) than the D70s, 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 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. 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 tend to be more expensive and 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.
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 D70s and the D40 have the same pixel density, as well as the same pixel size. It should, however, be noted that the D40 is a somewhat more recent model (by 1 year and 6 months) than the D70s, and its sensor might have benefitted from technological advances during this time.
The Nikon D70s has a native sensitivity range from ISO 200 to ISO 1600. The corresponding ISO settings for the Nikon D40 are ISO 200 to ISO 1600, with the possibility to increase the ISO range to 200-3200.
Technology-wise, both cameras are equipped with CCD (Charged Coupled Device) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 consideration, the D40 has a markedly higher DXO score than the D70s (overall score 6 points higher), which will translate into better image quality. The 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Feature comparison
Beyond body and sensor, cameras can and do differ across a range of features. The D70s and the D40 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 D70s (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 adjacent table lists some of the other core features of the Nikon D70s and Nikon D40 along with similar information for a selection of comparators.

Both the D70s and the D40 have been discontinued, but can regularly be found used on ebay. The D70s was replaced by the Nikon D80, while the D40 was followed by the Nikon D40X. Further information on the features and operation of the D70s and D40 can be found, respectively, in the Nikon D70s Manual (free pdf) or the online Nikon D40 Manual.
Review summary
So what is the bottom line? Is the Nikon D70s better than the Nikon D40 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Nikon D70s:
- 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 on the market for longer (launched in April 2005).
Arguments in favor of the Nikon D40:
- Better image quality: Scores markedly higher (6 points) in the DXO overall evaluation.
- More dynamic range: Captures a broader range 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 2.0") 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 will fit more readily into a bag.
- Less heavy: Has a lower weight (by 157g or 23 percent) and is thus easier to take along.
- More affordable: Was introduced into a lower priced category (44 percent cheaper at launch).
- More modern: Was introduced somewhat (1 year and 6 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the D40 is the clear winner of the contest (9 : 3 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.
How about other alternatives? Do the specifications of the Nikon D70s and the Nikon D40 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 says little about, for example, the shooting experience and imaging performance of the D70s and the D40 in practical situations. 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
