Canon 450D vs Olympus E-520
The Canon EOS 450D (called Canon XSi in some regions) and the Olympus E-520 are two digital cameras that were revealed to the public, respectively, in January 2008 and May 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (450D) and a Four Thirds (E-520) 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 450D and the Olympus E-520? 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.
The side-by-side display below illustrates the physical size and weight of the Canon 450D and the Olympus E-520. 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-520 is somewhat smaller (1 percent) than the Canon 450D. However, the E-520 is slightly heavier (2 percent) than the 450D. In this context, it is worth noting that neither the 450D nor the E-520 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 (450D) and the Four Thirds Lens Catalog (E-520).

The price is, of course, an important factor in any camera decision. 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-520 was launched at a somewhat lower price (by 13 percent) than the 450D, 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 450D features an APS-C sensor and the Olympus E-520 a Four Thirds sensor. The sensor area in the E-520 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 450D has a native 3:2 aspect ratio, while the one in the E-520 offers a 4:3 aspect.
With 12.2MP, the 450D offers a higher resolution than the E-520 (10MP), but the 450D nevertheless has larger individual pixels (pixel pitch of 5.19μm versus 4.74μm for the E-520) due to its larger sensor. However, the E-520 is a somewhat more recent model (by 3 months) than the 450D, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon 450D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 450D for good quality output (200 dots per inch) amounts to 21.4 x 14.2 inch or 54.3 x 36.2 cm, for very good quality (250 dpi) 17.1 x 11.4 inch or 43.4 x 28.9 cm, and for excellent quality (300 dpi) 14.2 x 9.5 inch or 36.2 x 24.1 cm. The corresponding values for the Olympus E-520 are 18.2 x 13.7 inch or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inch or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inch or 30.9 x 23.2 cm for excellent quality prints.
The Canon EOS 450D has a native sensitivity range from ISO 100 to ISO 1600. The Olympus E-520 offers exactly the same ISO settings.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). Of the two cameras under review, the 450D has a notably higher overall DXO score than the E-520 (overall score 6 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.5 bits higher color depth, 0.4 EV in additional dynamic range, and 0.3 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Apart from body and sensor, cameras can and do differ across a range of features. The 450D and the E-520 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 450D has a higher magnification than the one of the E-520 (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 450D and Olympus E-520 in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the E-520 and the 450D is in-body image stabilization (IBIS). The E-520 reduces the risk of handshake-induced blur with all attached lenses, while the 450D has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.
The 450D writes its imaging data to SDHC cards, while the E-520 uses Compact Flash or xD Picture cards. The E-520 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 450D only has one slot.
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 450D and Olympus E-520 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the 450D and the E-520 have been discontinued, but can regularly be found used on eBay. The 450D was replaced by the Canon 500D, while the E-520 does not have a direct successor. 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.
So what is the bottom line? Which of the two cameras – the Canon 450D or the Olympus E-520 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Advantages of the Canon EOS 450D:
- More detail: Offers more megapixels (12.2 vs 10MP) with a 13% higher linear resolution.
- Better image quality: Scores markedly higher (6 points) in the DXO overall assessment.
- Better low-light sensitivity: Requires less light for good images (0.3 stops ISO advantage).
- 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 2.7") for image review and settings control.
- More heavily discounted: Has been on the market for longer (launched in January 2008).
Reasons to prefer the Olympus E-520:
- Longer lasting: Gets more shots (750 versus 500) out of a single battery charge.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- 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 modern: Was introduced somewhat (3 months) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the 450D comes out slightly ahead of the E-520 (6 : 5 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. 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.
How about other alternatives? Do the specifications of the Canon 450D and the Olympus E-520 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 450D and the E-520 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 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.
Care should be taken when interpreting the review scores above, 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
