Canon 40D vs Nikon D700
The Canon EOS 40D and the Nikon D700 are two enthusiast cameras that were revealed to the public, respectively, in August 2007 and July 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (40D) and a full frame (D700) sensor. The Canon has a resolution of 10.1 megapixels, whereas the Nikon provides 12.1 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 Canon EOS 40D and the Nikon D700? 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.
The side-by-side display below illustrates the physical size and weight of the Canon 40D and the Nikon D700. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. 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 D700 is notably larger (15 percent) than the Canon 40D. Moreover, the D700 is markedly heavier (31 percent) than the 40D. It is noteworthy in this context that the D700 is splash and dust-proof, while the 40D 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 will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (40D) and the Nikon Lens Catalog (D700).
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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 40D was launched at a markedly lower price (by 57 percent) than the D700, 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.
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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon 40D features an APS-C sensor and the Nikon D700 a full frame sensor. The sensor area in the D700 is 159 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 12.1MP, the D700 offers a higher resolution than the 40D (10.1MP), but the D700 nevertheless has larger individual pixels (pixel pitch of 8.43μm versus 5.73μm for the 40D) due to its larger sensor. Moreover, the D700 is a somewhat more recent model (by 10 months) than the 40D, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Nikon D700 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D700 for good quality output (200 dots per inch) amounts to 21.3 x 14.2 inch or 54.1 x 36 cm, for very good quality (250 dpi) 17 x 11.3 inch or 43.2 x 28.8 cm, and for excellent quality (300 dpi) 14.2 x 9.4 inch or 36 x 24 cm. The corresponding values for the Canon 40D are 19.4 x 13 inch or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inch or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inch or 32.9 x 21.9 cm for excellent quality prints.
The Canon EOS 40D 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 D700 are ISO 200 to ISO 6400, with the possibility to increase the ISO range to 100-25600.
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 D700 offers substantially better image quality than the 40D (overall score 16 points higher). The advantage is based on 1.4 bits higher color depth, 0.9 EV in additional dynamic range, and 1.7 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.

Apart from body and sensor, cameras can and do differ across a range of features. The 40D and the D700 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 D700 has a higher magnification than the one of the 40D (0.72x vs 0.59x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon 40D, the Nikon D700, and comparable cameras.

The Nikon D700 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.
Concerning the storage of imaging data, both the 40D and the D700 write their files to Compact Flash cards.
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 Canon EOS 40D and Nikon D700 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.
Both the 40D and the D700 have been discontinued, but can regularly be found used on eBay. The 40D was replaced by the Canon 50D, while the D700 was followed by the Nikon D800. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Nikon websites.
So what is the bottom line? Is there a clear favorite between the Canon 40D and the Nikon D700? Which camera is better? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Canon EOS 40D:
- More compact: Is smaller (146x108mm vs 147x123mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 252g or 23 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced category (57 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in August 2007).
Reasons to prefer the Nikon D700:
- More detail: Has more megapixels (12.1 vs 10.1MP), which boosts linear resolution by 9%.
- Better image quality: Scores substantially higher (16 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.4 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (0.9 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (1.7 stops ISO advantage).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.72x vs 0.59x).
- More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
- Faster burst: Shoots at higher frequency (8 vs 6.5 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 (1000 versus 750) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- More modern: Was introduced somewhat (10 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the D700 is the clear winner of the contest (12 : 4 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. 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.
How about other alternatives? Do the specifications of the Canon 40D and the Nikon D700 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the 40D or the D700 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.
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 (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 ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
