Canon 400D vs Nikon D40
The Canon EOS 400D (called Canon XTi in some regions) and the Nikon D40 are two digital cameras that were announced, respectively, in August 2006 and November 2006. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The Canon has a resolution of 10.1 megapixels, whereas the Nikon provides 6 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 400D 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.
An illustration of the physical size and weight of the Canon 400D and the Nikon D40 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 D40 is notably larger (9 percent) than the Canon 400D. However, the D40 is markedly lighter (6 percent) than the 400D. In this context, it is worth noting that neither the 400D 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. Yet, since both cameras are based around an APS-C sensor, their respective lenses will tend to have similar dimensions and heft. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (400D) and the Nikon Lens Catalog (D40).

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 38 percent) than the 400D, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.
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. 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, but their sensors differ slightly in size. The sensor area in the D40 is 12 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (400D) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a smaller sensor, the Canon 400D offers a higher resolution of 10.1 megapixels, compared with 6 MP of the Nikon D40. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 5.71μm versus 7.85μm for the D40). It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.
The resolution advantage of the Canon 400D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 400D for good quality output (200 dots per inch) amounts to 19.4 x 13 inch or 49.4 x 32.9 cm, for very good quality (250 dpi) 15.6 x 10.4 inch or 39.5 x 26.3 cm, and for excellent quality (300 dpi) 13 x 8.6 inch or 32.9 x 21.9 cm. The corresponding values for the Nikon D40 are 15 x 10 inch or 38.2 x 25.4 cm for good quality, 12 x 8 inch or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inch or 25.5 x 16.9 cm for excellent quality prints.
The Canon EOS 400D has a native sensitivity range from ISO 100 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.
For many cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the 400D has a notably higher overall DXO score than the D40 (overall score 6 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.1 bits higher color depth, and 0.2 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.

Beyond body and sensor, cameras can and do differ across a range of features. The 400D 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 400D (0.53x vs 0.49x), 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 Canon 400D and Nikon D40 along with similar information for a selection of comparators.

Both the 400D and the D40 have been discontinued, but can regularly be found used on eBay. The 400D was replaced by the Canon 450D, 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 Canon and Nikon websites.
So how do things add up? Is there a clear favorite between the Canon 400D and the Nikon D40? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Canon EOS 400D:
- More detail: Offers more megapixels (10.1 vs 6MP) with a 29% higher linear resolution.
- Better image quality: Scores markedly higher (6 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.1 bits more color depth).
- Faster burst: Shoots at higher frequency (3 vs 2.5 flaps/sec) to capture the decisive moment.
Arguments in favor of the Nikon D40:
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.53x vs 0.49x).
- Longer lasting: Gets more shots (470 versus 370) out of a single battery charge.
- More affordable: Was introduced into a lower priced category (38 percent cheaper at launch).
If the number of relative strengths (bullet points above) is taken as a guide, the 400D comes out slightly ahead of the D40 (4 : 3 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 400D 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the 400D and the D40 in practical situations. 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 why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major 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 above review scores should be interpreted with care, 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 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.
