Canon 30D vs Nikon D40X
The Canon EOS 30D and the Nikon D40X are two digital cameras that were officially introduced, respectively, in February 2006 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 8.2 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 30D 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.
Body comparison: Canon 30D vs Nikon D40X
An illustration of the physical size and weight of the Canon 30D 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 perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.
The D40X can be obtained in two different colors (black, silver), while the 30D 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 (24 percent) than the Canon 30D. Moreover, the D40X is markedly lighter (34 percent) than the 30D. In this context, it is worth noting that neither the 30D 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 (30D) and the Nikon Lens Catalog (D40X).
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 D40X was launched at a markedly lower price (by 48 percent) than the 30D, 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.
Sensor comparison: Canon 30D vs Nikon D40X
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 10 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (30D) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 10MP, the D40X offers a higher resolution than the 30D (8.2MP), but the D40X has smaller individual pixels (pixel pitch of 6.11μm versus 6.42μm for the 30D). Yet, the D40X is a somewhat more recent model (by 1 year) than the 30D, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Nikon D40X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D40X for good quality output (200 dots per inch) amounts to 19.4 x 13 inch or 49.2 x 32.9 cm, for very good quality (250 dpi) 15.5 x 10.4 inch or 39.3 x 26.3 cm, and for excellent quality (300 dpi) 12.9 x 8.6 inch or 32.8 x 21.9 cm. The corresponding values for the Canon 30D are 17.5 x 11.7 inch or 44.5 x 29.7 cm for good quality, 14 x 9.3 inch or 35.6 x 23.7 cm for very good quality, and 11.7 x 7.8 inch or 29.7 x 19.8 cm for excellent quality prints.
The Canon EOS 30D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The Nikon D40X offers exactly the same ISO settings.
For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the D40X has a markedly higher DXO score than the 30D (overall score 4 points higher), which will translate into better image quality. The advantage is based on 0.9 bits higher color depth, 0.6 EV in additional dynamic range, and 0.5 stops of reduced 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: Canon 30D vs Nikon D40X
Apart from body and sensor, cameras can and do differ across a range of features. The 30D 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 30D has a higher magnification than the one of the D40X (0.56x vs 0.53x), 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 30D and Nikon D40X along with similar information for a selection of comparators.

One feature that is present on the 30D, but is missing on the D40X is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
The 30D writes its imaging data to Compact Flash cards, while the D40X uses SDHC cards.
Connectivity comparison: Canon 30D vs Nikon D40X
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 30D and Nikon D40X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 30D (unlike the D40X) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 30D and the D40X have been discontinued, but can regularly be found used on eBay. The 30D was replaced by the Canon 40D, while the D40X was followed by the Nikon D60 . 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.
Review summary: Canon 30D vs Nikon D40X
So what is the bottom line? Is the Canon 30D better than the Nikon D40X or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon EOS 30D:
- Better low-light sensitivity: Requires less light for good images (0.5 stops ISO advantage).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.56x vs 0.53x).
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (750 versus 520) on a single battery charge.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More heavily discounted: Has been on the market for longer (launched in February 2006).
Advantages of the Nikon D40X:
- More detail: Has more megapixels (10 vs 8.2MP), which boosts linear resolution by 11%.
- Better image quality: Scores markedly higher (4 points) in the DXO overall evaluation.
- More dynamic range: Captures a broader range of light and dark details (0.6 EV of extra DR).
- More compact: Is smaller (124x94mm vs 144x106mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 263g or 34 percent) and is thus easier to take along.
- More affordable: Was introduced into a lower priced category (48 percent cheaper at launch).
- More modern: Was introduced somewhat (1 year) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the 30D comes out slightly ahead of the D40X (8 : 7 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 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 30D 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 30D or the D40X perform in practice. 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: Canon 30D vs Nikon D40X
This is why expert reviews are important. 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 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
