Canon 400D vs D30
The Canon EOS 400D (called Canon XTi in some regions) and the Canon EOS-D30 are two digital cameras that were revealed to the public, respectively, in August 2006 and May 2000. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 400D has a resolution of 10.1 megapixels, whereas the D30 provides 3.1 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 400D and the Canon EOS-D30? 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 physical size and weight of the Canon 400D and the Canon D30 are illustrated 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon D30 is considerably larger (50 percent) than the Canon 400D. Moreover, the D30 is substantially heavier (35 percent) than the 400D. In this context, it is worth noting that neither the 400D nor the D30 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 Canon EF Lens Catalog.

Any camera decision will obviously take relative prices into account. 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 400D was launched at a markedly lower price (by 73 percent) than the D30, 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.
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. 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. They nevertheless have the same format factor of 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 10.1MP, the 400D offers a higher resolution than the D30 (3.1MP), but the 400D has smaller individual pixels (pixel pitch of 5.71μm versus 10.29μm for the D30). However, the 400D is a much more recent model (by 6 years and 3 months) than the D30, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
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 Canon D30 are 10.8 x 7.2 inch or 27.4 x 18.3 cm for good quality, 8.6 x 5.8 inch or 21.9 x 14.6 cm for very good quality, and 7.2 x 4.8 inch or 18.3 x 12.2 cm for excellent quality prints.
The Canon EOS 400D has a native sensitivity range from ISO 100 to ISO 1600. The Canon EOS-D30 offers exactly the same ISO settings.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Beyond body and sensor, cameras can and do differ across a range of features. The 400D and the D30 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 D30 has a higher magnification than the one of the 400D (0.54x 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 Canon D30 along with similar information for a selection of comparators.

One feature that is present on the D30, but is missing on the 400D 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.
Concerning the storage of imaging data, both the 400D and the D30 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 400D and Canon EOS-D30 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon D30 (unlike the 400D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 400D and the D30 have been discontinued, but can regularly be found used on eBay. The D30 was replaced by the Canon D60, while the 400D was followed by the Canon 450D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what conclusions can be drawn? Is the Canon 400D better than the Canon D30 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Canon EOS 400D:
- More detail: Offers more megapixels (10.1 vs 3.1MP) with a 80% higher linear resolution.
- Larger screen: Has a bigger rear LCD (2.5" vs 1.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (230k vs 114k dots).
- More compact: Is smaller (127x84mm vs 150x107mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 194g or 26 percent) and hence easier to carry around.
- Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.0).
- More affordable: Was introduced into a lower priced category (73 percent cheaper at launch).
- More modern: Reflects 6 years and 3 months of technical progress since the D30 launch.
Arguments in favor of the Canon EOS-D30:
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.54x vs 0.49x).
- Easier setting verification: Features a control panel on top to check shooting parameters.
- Longer lasting: Gets more shots (540 versus 370) out of a single battery charge.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More heavily discounted: Has been around for much longer (launched in May 2000).
If the count of individual advantages (bullet points above) is taken as a guide, the 400D emerges as the winner of the contest (8 : 5 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 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 400D and the Canon D30 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 remains incomplete and does no justice, for example, to the way the 400D or the D30 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 why expert reviews 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 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
