Canon D30 versus Canon 20D

The Canon EOS-D30 and the Canon EOS 20D are two digital cameras that were revealed to the public, respectively, in May 2000 and August 2004. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The Canon D30 has a resolution of 3.1 megapixel, whereas the 20D provides 8.2 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon D30 vs Canon 20D

An illustration of the physical size and weight of the Canon D30 and the Canon 20D is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All size dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the Canon D30 – represents the basis or 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 20D is notably smaller (5 percent) than the Canon D30. However, the 20D is slightly heavier (3 percent) than the Canon D30. In this context, it is worth noting that neither the Canon D30 nor the 20D 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 find an overview of suitable optics in the Canon EF Lens Catalog.

Concerning battery life, the Canon D30 gets 540 shots out of its BP-511 battery, while the 20D can take 700 images on a single charge of its BP-511A power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

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 20D was launched at a markedly lower price (by 50 percent) than the Canon 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.


Sensor comparison: Canon D30 vs Canon 20D

The size of the imaging sensor is a crucial determinant 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. 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 20D is 3 percent bigger. 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.

Sensor size

With 8.2MP, the 20D offers a higher resolution than the Canon D30 (3.1MP), but the 20D has smaller individual pixels (pixel pitch of 6.42μm versus 10.29μm for the Canon D30). Yet, the 20D is a much more recent model (by 4 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 pixel-units.

Sensor resolution

Consistent information on actual sensor performance is available from DXO Mark for most 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.

Neither the Canon D30 nor the 20D offer Live View, so that they cannot project the live image that the sensor receives onto the rear screen. Moreover, both cameras are still-image focused and cannot record videos.

Feature comparison: Canon D30 vs Canon 20D

Apart from body and sensor, cameras can and do differ across a range of features. The Canon D30 and the 20D 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 adjacent table lists some of the other core features of the Canon D30 and Canon 20D along with similar information for a selection of comparators. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the Canon D30 and the 20D have been discontinued, but can regularly be found used on eBay. The Canon D30 was replaced by the Canon D60, while the 20D was followed by the Canon 30D.

Review summary: Canon D30 vs Canon 20D

So how do things add up? Which of the two cameras – the Canon D30 or the Canon 20D – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Canon EOS-D30:

  • More heavily discounted: Has been available for much longer (launched in May 2000).

Advantages of the Canon EOS 20D:

  • More detail: Has more megapixels (8.2 vs 3.1MP), which boosts linear resolution by 62%.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (700 versus 540) out of a single battery charge.
  • More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
  • More modern: Reflects 4 years and 3 months of technical progress since the Canon D30 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 20D is the clear winner of the contest (6 : 1 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.

Canon D30 01:06 20D

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the Canon D30 and the 20D in practical situations. 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 where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
