Canon Rebel vs Olympus E-450
The Canon EOS Digital Rebel (called Canon 300D in some regions) and the Olympus E-450 are two digital cameras that were revealed to the public, respectively, in August 2003 and March 2009. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (Rebel) and a Four Thirds (E-450) sensor. The Canon has a resolution of 6.3 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 Digital Rebel and the Olympus E-450? 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 physical size and weight of the Canon Rebel and the Olympus E-450 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 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 Olympus E-450 is notably smaller (16 percent) than the Canon Rebel. Moreover, the E-450 is markedly lighter (32 percent) than the Rebel. In this context, it is worth noting that neither the Rebel nor the E-450 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 (Rebel) and the Four Thirds Lens Catalog (E-450).
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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-450 was launched at a markedly lower price (by 44 percent) than the Rebel, which puts it into a different market segment. 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.
The size of the imaging sensor is a crucial determinant 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 Rebel features an APS-C sensor and the Olympus E-450 a Four Thirds sensor. The sensor area in the E-450 is 34 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 Rebel has a native 3:2 aspect ratio, while the one in the E-450 offers a 4:3 aspect.
In terms of underlying technology, both cameras are build around CMOS sensors.
Despite having a smaller sensor, the E-450 offers a higher resolution of 10 megapixels, compared with 6.3 MP of the Rebel. 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 7.38μm for the Rebel). However, it should be noted that the E-450 is much more recent (by 5 years and 7 months) than the Rebel, 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-450 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-450 for good quality output (200 dots per inch) amounts to 18.2 x 13.7 inches or 46.3 x 34.7 cm, for very good quality (250 dpi) 14.6 x 10.9 inches or 37.1 x 27.8 cm, and for excellent quality (300 dpi) 12.2 x 9.1 inches or 30.9 x 23.2 cm. The corresponding values for the Canon Rebel are 15.4 x 10.2 inches or 39 x 26 cm for good quality, 12.3 x 8.2 inches or 31.2 x 20.8 cm for very good quality, and 10.2 x 6.8 inches or 26 x 17.3 cm for excellent quality prints.
The Canon EOS Digital Rebel has a native sensitivity range from ISO 100 to ISO 1600. The Olympus E-450 offers exactly the same ISO settings.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Apart from body and sensor, cameras can and do differ across a variety of features. The Rebel and the E-450 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 Rebel has a higher magnification than the one of the E-450 (0.55x vs 0.46x), 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 Rebel, the Olympus E-450, and comparable cameras.
The Rebel writes its imaging data to Compact Flash cards, while the E-450 uses Compact Flash or xD Picture cards. The E-450 features dual card slots, which can be very useful in case a memory card fails. In contrast, the Rebel 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 Digital Rebel and Olympus E-450 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the Rebel and the E-450 have been discontinued, but can regularly be found used on eBay. The Rebel was replaced by the Canon XT, while the E-450 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 conclusions can be drawn? Is there a clear favorite between the Canon Rebel and the Olympus E-450? Which camera is better? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Canon EOS Digital Rebel:
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.55x vs 0.46x).
- More heavily discounted: Has been available for much longer (launched in August 2003).
Arguments in favor of the Olympus E-450:
- More detail: Has more megapixels (10 vs 6.3MP), which boosts linear resolution by 24%.
- Larger screen: Has a bigger rear LCD (2.7" vs 1.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (215k vs 118k dots).
- Faster burst: Shoots at higher frequency (3.5 vs 2.5 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (130x91mm vs 142x99mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 209g or 32 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (500 versus 400) out of a single battery charge.
- Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.

If the count of individual advantages (bullet points above) is taken as a guide, the E-450 is the clear winner of the contest (11 : 2 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.

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 Rebel or the E-450. 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.
This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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.

The above review scores should be interpreted with care, 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.
