Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 40D 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.
Body comparison: Canon 40D vs Canon D30
The physical size and weight of the Canon 40D and the Canon D30 are illustrated 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 Canon D30 is somewhat larger (2 percent) than the Canon 40D. However, the Canon D30 is markedly lighter (9 percent) than the 40D. In this context, it is worth noting that neither the 40D nor the Canon 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.
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 40D was launched at a markedly lower price (by 57 percent) than the Canon D30, 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.
Sensor comparison: Canon 40D vs Canon D30
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. 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 Canon D30 is 1 percent smaller. 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 40D offers a higher resolution than the Canon D30 (3.1MP), but the 40D has smaller individual pixels (pixel pitch of 5.73μm versus 10.29μm for the Canon D30). However, the 40D is a much more recent model (by 7 years and 3 months) than the Canon 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 40D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 40D 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 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 Canon EOS-D30 are ISO 100 to ISO 1600 (no boost).
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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Feature comparison: Canon 40D vs Canon D30
Apart from body and sensor, cameras can and do differ across a variety of features. The 40D and the Canon 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 40D has a higher magnification than the one of the Canon D30 (0.59x vs 0.54x), 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 Canon D30, and comparable cameras.

Both the 40D and the Canon D30 have been discontinued, but can regularly be found used on eBay. The Canon D30 was replaced by the Canon D60, while the 40D was followed by the Canon 50D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
Review summary: Canon 40D vs Canon D30
So what conclusions can be drawn? Is there a clear favorite between the Canon 40D and the Canon D30? Which camera is better? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Canon EOS 40D:
- More detail: Offers more megapixels (10.1 vs 3.1MP) with a 80% higher linear resolution.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.59x vs 0.54x).
- Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (230k vs 114k dots).
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (6.5 vs 3 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (750 versus 540) on a single battery charge.
- Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.0).
- More affordable: Was introduced into a lower priced category (57 percent cheaper at launch).
- More modern: Reflects 7 years and 3 months of technical progress since the Canon D30 launch.
Arguments in favor of the Canon EOS-D30:
- 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 40D is the clear winner of the match-up (10 : 1 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 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 40D or the Canon D30. 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 40D vs Canon D30
This is why hands-on reviews by experts 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 above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price 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.
