Canon 400D vs Olympus E-330

The Canon EOS 400D (called Canon XTi in some regions) and the Olympus Evolt E-330 are two digital cameras that were announced, respectively, in August 2006 and January 2006. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (400D) and a Four Thirds (E-330) sensor. The Canon has a resolution of 10.1 megapixels, whereas the Olympus provides 7.4 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 Olympus Evolt E-330? 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 400D and the Olympus E-330 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 measures are rounded to the nearest millimeter.

Size Canon 400D vs Olympus E-330
Compare 400D versus E-330 top
Comparison 400D or E-330 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-330 is notably larger (14 percent) than the Canon 400D. Moreover, the E-330 is markedly heavier (15 percent) than the 400D. In this context, it is worth noting that neither the 400D nor the E-330 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 (400D) and the Four Thirds Lens Catalog (E-330).

Concerning battery life, the 400D gets 370 shots out of its NB-2LH battery, while the E-330 can take 750 images on a single charge of its BLM-1 power pack.

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, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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 400D was launched at a somewhat lower price (by 20 percent) than the E-330, which makes it more attractive for photographers on a tight budget. 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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 400D features an APS-C sensor and the Olympus E-330 a Four Thirds sensor. The sensor area in the E-330 is 32 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 400D has a native 3:2 aspect ratio, while the one in the E-330 offers a 4:3 aspect.

Canon 400D and Olympus E-330 sensor measures

With 10.1MP, the 400D offers a higher resolution than the E-330 (7.4MP), but the 400D nevertheless has larger individual pixels (pixel pitch of 5.71μm versus 5.51μm for the E-330) due to its larger sensor. Moreover, the 400D is a somewhat more recent model (by 6 months) than the E-330, and its sensor might have benefitted from technological advances during this time that further 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 inches or 49.4 x 32.9 cm, for very good quality (250 dpi) 15.6 x 10.4 inches or 39.5 x 26.3 cm, and for excellent quality (300 dpi) 13 x 8.6 inches or 32.9 x 21.9 cm. The corresponding values for the Olympus E-330 are 15.7 x 11.8 inches or 39.8 x 29.9 cm for good quality, 12.5 x 9.4 inches or 31.9 x 23.9 cm for very good quality, and 10.5 x 7.8 inches or 26.6 x 19.9 cm for excellent quality prints.

The Canon EOS 400D has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Olympus Evolt E-330 are ISO 100 to ISO 400, with the possibility to increase the ISO range to 100-1600.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The 400D and the E-330 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 400D has a higher magnification than the one of the E-330 (0.49x vs 0.47x), 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 400D, the Olympus E-330, and comparable cameras.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon 400D and the Olympus E-330? Which camera is better? The listing below highlights the relative strengths of the two models.

ilogo

Reasons to prefer the Canon EOS 400D:

  • More detail: Offers more megapixels (10.1 vs 7.4MP) with a 19% higher linear resolution.
  • Better image quality: Features a larger and more technologically advanced imaging sensor.
  • Richer colors: The sensor size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.49x vs 0.47x).
  • More compact: Is smaller (127x84mm vs 140x87mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 81g or 13 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced segment (20 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 6 months after the E-330).

ilogo

Arguments in favor of the Olympus Evolt E-330:

  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Longer lasting: Gets more shots (750 versus 370) out of a single battery charge.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been on the market for longer (launched in January 2006).

If the count of individual advantages (bullet points above) is taken as a guide, the 400D is the clear winner of the match-up (10 : 4 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.

400D 10:04 E-330

How about other alternatives? Do the specifications of the Canon 400D and the Olympus E-330 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 400D or the E-330. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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. 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.
