Canon 450D vs Rebel

The Canon EOS 450D (called Canon XSi in some regions) and the Canon EOS Digital Rebel (labelled Canon 300D in some countries) are two digital cameras that were officially introduced, respectively, in January 2008 and August 2003. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 450D has a resolution of 12.2 megapixels, whereas the Rebel provides 6.3 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 Canon EOS Digital Rebel? 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 450D and the Canon Rebel is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.

Compare 450D versus Rebel top
Comparison 450D or Rebel rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon Rebel is notably larger (11 percent) than the Canon 450D. Moreover, the Rebel is markedly heavier (24 percent) than the 450D. In this context, it is worth noting that neither the 450D nor the Rebel 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the 450D gets 500 shots out of its LP-E5 battery, while the Rebel can take 400 images on a single charge of its BP-511 power pack.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 450D was launched at a somewhat lower price (by 11 percent) than the Rebel, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the Rebel is 4 percent bigger. They nevertheless have the same format factor of 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 450D and Canon Rebel sensor measures

Despite having a slightly smaller sensor, the Canon 450D offers a higher resolution of 12.2 megapixels, compared with 6.3 MP of the Canon 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 5.19μm versus 7.38μm for the Rebel). However, it should be noted that the 450D is much more recent (by 4 years and 5 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 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 Canon Rebel are 15.4 x 10.2 inch or 39 x 26 cm for good quality, 12.3 x 8.2 inch or 31.2 x 20.8 cm for very good quality, and 10.2 x 6.8 inch or 26 x 17.3 cm for excellent quality prints.

The Canon EOS 450D has a native sensitivity range from ISO 100 to ISO 1600. The Canon EOS Digital Rebel offers exactly the same ISO settings.

450D versus Rebel MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under review, the 450D has a notably higher overall DXO score than the Rebel (overall score 6 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.9 bits higher color depth, 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.

The 450D offers Live View, so that it can project the live image that the sensor receives onto the rear screen for framing. The Rebel lacks this capability. Both cameras are still-image focused and cannot record videos.
 

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 450D and the Rebel 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 450D (0.55x vs 0.54x), 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 Canon Rebel in connection with corresponding information for a sample of similar cameras.

Both the 450D and the Rebel have been discontinued, but can regularly be found used on eBay. The Rebel was replaced by the Canon XT, while the 450D was followed by the Canon 500D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.


Review summary

So what is the bottom line? Which of the two cameras – the Canon 450D or the Canon Rebel – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.


Reasons to prefer the Canon EOS 450D:

  • More detail: Offers more megapixels (12.2 vs 6.3MP) with a 39% 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 screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (230k vs 118k dots).
  • Faster burst: Shoots at higher frequency (3.5 vs 2.5 flaps/sec) to capture the decisive moment.
  • Less heavy: Is lighter (by 125g or 19 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (500 versus 400) on a single battery charge.
  • Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
  • More affordable: Was introduced into a lower priced segment (11 percent cheaper at launch).
  • More modern: Reflects 4 years and 5 months of technical progress since the Rebel launch.


Advantages of the Canon EOS Digital Rebel:

  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.55x vs 0.54x).
  • More heavily discounted: Has been around for much longer (launched in August 2003).

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

450D 11:02 Rebel

How about other alternatives? Do the specifications of the Canon 450D and the Canon Rebel 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 450D or the Rebel perform in practice. 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 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

The review scores listed above should be treated 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
