Canon D30 vs Olympus E-400

The Canon EOS-D30 and the Olympus E-400 are two digital cameras that were officially introduced, respectively, in May 2000 and September 2006. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (Canon D30) and a Four Thirds (E-400) sensor. The Canon has a resolution of 3.1 megapixels, whereas the Olympus 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-D30 and the Olympus E-400? 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

The physical size and weight of the Canon D30 and the Olympus E-400 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 size dimensions are rounded to the nearest millimeter.

Compare Canon D30 versus E-400 top
Comparison Canon D30 or E-400 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-400 is notably smaller (26 percent) than the Canon D30. Moreover, the E-400 is substantially lighter (42 percent) than the Canon D30. In this context, it is worth noting that neither the Canon D30 nor the E-400 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (Canon D30) and the Four Thirds Lens Catalog (E-400).

Concerning battery life, the Canon D30 gets 540 shots out of its BP-511 battery, while the E-400 can take 500 images on a single charge of its BLS-1 power pack.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

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 E-400 was launched at a markedly lower price (by 77 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.

 

Sensor comparison

The size of the imaging sensor is a crucial determinant 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. 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.

Of the two cameras under consideration, the Canon D30 features an APS-C sensor and the Olympus E-400 a Four Thirds sensor. The sensor area in the E-400 is 31 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.0. The sensor in the Canon D30 has a native 3:2 aspect ratio, while the one in the E-400 offers a 4:3 aspect.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Canon D30 and Olympus E-400 sensor measures

Despite having a smaller sensor, the E-400 offers a higher resolution of 10 megapixels, compared with 3.1 MP of the Canon D30. 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 4.74μm versus 10.29μm for the Canon D30). However, it should be noted that the E-400 is much more recent (by 6 years and 3 months) than the Canon D30, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Olympus E-400 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-400 for good quality output (200 dots per inch) amounts to 18.2 x 13.7 inch or 46.3 x 34.7 cm, for very good quality (250 dpi) 14.6 x 10.9 inch or 37.1 x 27.8 cm, and for excellent quality (300 dpi) 12.2 x 9.1 inch or 30.9 x 23.2 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-D30 has a native sensitivity range from ISO 100 to ISO 1600. The Olympus E-400 offers exactly the same ISO settings.

Canon D30 versus E-400 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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").

Neither the Canon D30 nor the E-400 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

Apart from body and sensor, cameras can and do differ across a variety of features. The Canon D30 and the E-400 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 Canon D30 has a higher magnification than the one of the E-400 (0.54x vs 0.46x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon D30 and Olympus E-400 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the Canon D30, but is missing on the E-400 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 Canon D30 writes its imaging data to Compact Flash cards, while the E-400 uses Compact Flash or xD Picture cards. The E-400 features dual card slots, which can be very useful in case a memory card fails. In contrast, the Canon D30 only has one slot.

 

Connectivity comparison

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-D30 and Olympus E-400 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 E-400) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the Canon D30 and the E-400 have been discontinued, but can regularly be found used on eBay. The Canon D30 was replaced by the Canon D60, while the E-400 was followed by the Olympus E-410. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Olympus websites.


Review summary

So what is the bottom line? Is there a clear favorite between the Canon D30 and the Olympus E-400? Which camera is better? The listing below highlights the relative strengths of the two models.

ilogo

Advantages of the Canon EOS-D30:

  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.54x vs 0.46x).
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More heavily discounted: Has been available for much longer (launched in May 2000).

ilogo

Reasons to prefer the Olympus E-400:

  • More detail: Has more megapixels (10 vs 3.1MP), which boosts linear resolution by 76%.
  • 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 (215k vs 114k dots).
  • More compact: Is smaller (130x91mm vs 150x107mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 315g or 42 percent) and is thus easier to take along.
  • Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.0).
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More affordable: Was introduced into a lower priced category (77 percent cheaper at launch).
  • More modern: Reflects 6 years and 3 months of technical progress since the Canon D30 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the E-400 is the clear winner of the contest (9 : 4 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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.

Canon D30 04:09 E-400

How about other alternatives? Do the specifications of the Canon D30 and the Olympus E-400 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 Canon D30 or the E-400 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

This is where reviews by experts come in. 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
