Body comparison: Olympus E-400 vs Canon 30D
The side-by-side display below illustrates the physical size and weight of the Olympus E-400 and the Canon 30D. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size 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 30D is notably larger (29 percent) than the Olympus E-400. Moreover, the 30D is substantially heavier (80 percent) than the E-400. In this context, it is worth noting that neither the E-400 nor the 30D 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 Four Thirds Lens Catalog (E-400) and the Canon EF Lens Catalog (30D).
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera.

Any camera decision will naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The E-400 was launched at a markedly lower price (by 50 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.
Sensor comparison: Olympus E-400 vs Canon 30D
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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 Olympus E-400 features a Four Thirds sensor and the Canon 30D an APS-C sensor. The sensor area in the 30D is 50 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.6. The sensor in the E-400 has a native 4:3 aspect ratio, while the one in the 30D offers a 3:2 aspect.
In terms of underlying technology, both cameras are build around CMOS sensors.
Despite having a smaller sensor, the Olympus E-400 offers a higher resolution of 10 megapixels, compared with 8.2 MP of the Canon 30D. 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 6.42μm for the 30D). However, it should be noted that the E-400 is a somewhat more recent model (by 6 months) than the 30D, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.
The Olympus E-400 has a native sensitivity range from ISO 100 to ISO 1600 The corresponding ISO settings for the Canon EOS 30D are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200..
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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: Olympus E-400 vs Canon 30D
Apart from body and sensor, cameras can and do differ across a range of features. The E-400 and the 30D 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 E-400 (0.56x 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 Olympus E-400 and Canon 30D in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 30D, 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 E-400 writes its imaging data to Compact Flash or xD Picture cards, while the 30D uses Compact Flash cards. The E-400 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 30D only has one slot.
Connectivity comparison: Olympus E-400 vs Canon 30D
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 Olympus E-400 and Canon EOS 30D 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 E-400) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the E-400 and the 30D have been discontinued, but can regularly be found used on eBay. The 30D was replaced by the Canon 40D, while the E-400 was followed by the Olympus E-410. Further information on the two cameras, as well as related accessories, can be found on the official Olympus and Canon websites.
Review summary: Olympus E-400 vs Canon 30D
So how do things add up? Is the Olympus E-400 better than the Canon 30D or vice versa? The listing below highlights the relative strengths of the two models.

- 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).
If the count of individual advantages (bullet points above) is taken as a guide, the 30D is the clear winner of the contest (11 : 6 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.
Do the specifications of the Olympus E-400 and the Canon 30D place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing.In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the E-400 and the 30D 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.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
