Canon 450D versus Canon 40D

The Canon EOS 450D (called Canon XSi in some regions) and the Canon EOS 40D are two digital cameras that were revealed to the public, respectively, in January 2008 and August 2007. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 450D has a resolution of 12.2 megapixel, whereas the 40D provides 10.1 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 450D vs Canon 40D

An illustration of the physical size and weight of the Canon 450D and the Canon 40D is provided 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. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the 450D – represents 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 40D is notably larger (25 percent) than the Canon 450D. Moreover, the 40D is substantially heavier (57 percent) than the 450D. In this context, it is worth noting that neither the 450D nor the 40D 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 find an overview of suitable optics in the Canon EF Lens Catalog.

Concerning battery life, the 450D gets 500 shots out of its LP-E5 battery, while the 40D can take 750 images on a single charge of its BP-511A power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. 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 markedly lower price (by 38 percent) than the 40D, 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.

 

Sensor comparison: Canon 450D vs Canon 40D

The size of the sensor inside a digital camera is one of the key determinants 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. 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 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 40D is 1 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 40D sensor measures

Despite having a slightly smaller sensor, the Canon 450D offers a higher resolution of 12.2 megapixel, compared with 10.1 MP of the Canon 40D. This megapixel 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 5.73μm for the 40D). However, it should be noted that the 450D is a somewhat more recent model (by 5 months) than the 40D, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.

450D versus 40D MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Both the 450D and the 40D offer Live View, so that they make it possible to use the rear screen for framing. Both cameras are still-image focused and cannot record videos.
 

Feature comparison: Canon 450D vs Canon 40D

Apart from body and sensor, cameras can and do differ across a range of features. The 450D and the 40D 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 following table reports on some other key feature differences and similarities of the Canon 450D, the Canon 40D, and comparable cameras. The full specs-sheets can be found in the camera manual or in the dpreview camera hub.

One feature that is present on the 40D, but is missing on the 450D is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The 450D writes its imaging data to SDHC cards, while the 40D uses Compact Flash cards.

Review summary: Canon 450D vs Canon 40D

So what is the bottom line? Is there a clear favorite between the Canon 450D and the Canon 40D? The listing below highlights the relative strengths of the two models.


Arguments in favor of the Canon EOS 450D:

  • More detail: Offers more megapixels (12.2 vs 10.1MP) with a 10% higher linear resolution.
  • More compact: Is smaller (129x98mm vs 146x108mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 298g or 36 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (38 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 5 months after the 40D).


Reasons to prefer the Canon EOS 40D:

  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (6.5 vs 3.5 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (750 versus 500) out of a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in August 2007).

If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (5 points each). 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.

450D 05:05 40D

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the 450D or the 40D handle or perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
