Canon 450D vs Nikon D40X
The Canon EOS 450D (called Canon XSi in some regions) and the Nikon D40X are two digital cameras that were announced, respectively, in January 2008 and March 2007. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The Canon has a resolution of 12.2 megapixels, whereas the Nikon provides 10 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 450D and the Nikon D40X? 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 450D and the Nikon D40X is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
The D40X can be obtained in two different colors (black, silver), while the 450D is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D40X is notably smaller (8 percent) than the Canon 450D. Moreover, the D40X is slightly lighter (0 percent) than the 450D. In this context, it is worth noting that neither the 450D nor the D40X 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 (450D) and the Nikon Lens Catalog (D40X).
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

The price is, of course, an important factor in any camera decision. 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 D40X was somewhat cheaper (by 9 percent) than the 450D at launch, but both cameras fall into the same price category. 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.
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. 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 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 D40X is 13 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (450D) 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 450D offers a higher resolution of 12.2 megapixels, compared with 10 MP of the Nikon D40X. 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 5.19μm versus 6.11μm for the D40X). However, it should be noted that the 450D is a somewhat more recent model (by 10 months) than the D40X, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.
The resolution advantage of the Canon 450D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 450D for good quality output (200 dots per inch) amounts to 21.4 x 14.2 inches or 54.3 x 36.2 cm, for very good quality (250 dpi) 17.1 x 11.4 inches or 43.4 x 28.9 cm, and for excellent quality (300 dpi) 14.2 x 9.5 inches or 36.2 x 24.1 cm. The corresponding values for the Nikon D40X are 19.4 x 13 inches or 49.2 x 32.9 cm for good quality, 15.5 x 10.4 inches or 39.3 x 26.3 cm for very good quality, and 12.9 x 8.6 inches or 32.8 x 21.9 cm for excellent quality prints.
The Canon EOS 450D has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Nikon D40X are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.
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. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Beyond body and sensor, cameras can and do differ across a range of features. The 450D and the D40X 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 450D has a higher magnification than the one of the D40X (0.54x vs 0.53x), 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 450D, the Nikon D40X, and comparable cameras.

Concerning the storage of imaging data, both the 450D and the D40X write their files to SDHC 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 450D and Nikon D40X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the 450D and the D40X have been discontinued, but can regularly be found used on eBay. The D40X was replaced by the Nikon D60 , while the 450D was followed by the Canon 500D. 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 the Canon 450D better than the Nikon D40X or vice versa? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Canon EOS 450D:
- More detail: Offers more megapixels (12.2 vs 10MP) with a 10% higher linear resolution.
- Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.54x vs 0.53x).
- Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
- Faster burst: Shoots at higher frequency (3.5 vs 3 flaps/sec) to capture the decisive moment.
- More modern: Is somewhat more recent (announced 10 months after the D40X).
Arguments in favor of the Nikon D40X:
- More dynamic range: Captures a broader range of light and dark details (0.6 EV of extra DR).
- More heavily discounted: Has been on the market for longer (launched in March 2007).
If the count of relative strengths (bullet points above) is taken as a measure, the 450D is the clear winner of the match-up (6 : 2 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 Canon 450D and the Nikon D40X 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 incomplete and does no justice, for example, to the way the 450D or the D40X perform in practice. 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.
This is why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], 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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
