Canon XSi vs Olympus E-400

The Canon EOS Rebel XSi (called Canon 450D in some regions) and the Olympus E-400 are two digital cameras that were officially introduced, respectively, in January 2008 and September 2006. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (XSi) and a Four Thirds (E-400) sensor. The Canon has a resolution of 12.2 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 Rebel XSi 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

An illustration of the physical size and weight of the Canon XSi and the Olympus E-400 is provided 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 width, height and depth measures are rounded to the nearest millimeter.

Size Canon XSi vs Olympus E-400
Compare XSi versus E-400 top
Comparison XSi 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 (6 percent) than the Canon XSi. Moreover, the E-400 is markedly lighter (17 percent) than the XSi. In this context, it is worth noting that neither the XSi 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 (XSi) and the Four Thirds Lens Catalog (E-400).

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, you can navigate to the CAM-parator app and make your selection from a broad list of cameras 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-400 was launched at a somewhat lower price (by 13 percent) than the XSi, which makes it more attractive for photographers on a tight budget. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 Canon XSi features an APS-C sensor and the Olympus E-400 a Four Thirds sensor. The sensor area in the E-400 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 XSi has a native 3:2 aspect ratio, while the one in the E-400 offers a 4:3 aspect.

In terms of underlying technology, both cameras are build around CMOS sensors.

Canon XSi and Olympus E-400 sensor measures

With 12.2MP, the XSi offers a higher resolution than the E-400 (10MP), but the XSi nevertheless has larger individual pixels (pixel pitch of 5.19μm versus 4.74μm for the E-400) due to its larger sensor. Moreover, the XSi is a somewhat more recent model (by 1 year and 4 months) than the E-400, 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 XSi implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the XSi for good quality output (200 dots per inch) amounts to 21.4 x 14.2 inches or 54.3 x 36.2 cm, for very good quality (250 dpi) 17.1 x 11.4 inches or 43.4 x 28.9 cm, and for excellent quality (300 dpi) 14.2 x 9.5 inches or 36.2 x 24.1 cm. The corresponding values for the Olympus E-400 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.

The Canon EOS Rebel XSi has a native sensitivity range from ISO 100 to ISO 1600. The Olympus E-400 offers exactly the same ISO settings.

The XSi offers Live View, so that it can project the live image that the sensor receives onto the rear screen for framing. The E-400 lacks this capability. Both cameras are still-image focused and cannot record videos.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The XSi 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 XSi 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 XSi and Olympus E-400 in connection with corresponding information for a sample of similar cameras.

Both the XSi and the E-400 have been discontinued, but can regularly be found used on eBay. The E-400 was replaced by the Olympus E-410, while the XSi was followed by the Canon T1i. 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? Which of the two cameras – the Canon XSi or the Olympus E-400 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Reasons to prefer the Canon EOS Rebel XSi:

  • More detail: Offers more megapixels (12.2 vs 10MP) with a 13% 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 (0.54x vs 0.46x).
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
  • Faster burst: Shoots at higher frequency (3.5 vs 3 flaps/sec) to capture the decisive moment.
  • More modern: Is somewhat more recent (announced 1 year and 4 months after the E-400).

ilogo

Advantages of the Olympus E-400:

  • Less heavy: Has a lower weight (by 89g or 17 percent) and is thus easier to take along.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More affordable: Was released into a lower priced segment (13 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in September 2006).

If the count of relative strengths (bullet points above) is taken as a measure, the XSi is the clear winner of the match-up (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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

XSi 09:04 E-400

How about other alternatives? Do the specifications of the Canon XSi 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 says little about, for example, the shooting experience and imaging performance of the XSi and the E-400 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.

Expert reviews

This is why expert reviews 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], digitalcameraworld [DCW], 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.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
