Canon 400D versus Canon 450D

The Canon EOS 400D (called Canon XTi in some regions) and the Canon EOS 450D (labelled Canon XSi in some countries) are two digital cameras that were officially introduced, respectively, in August 2006 and January 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 400D has a resolution of 10.1 megapixel, whereas the 450D provides 12.2 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 400D vs Canon 450D

The physical size and weight of the Canon 400D and the Canon 450D are illustrated 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. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the 400D – 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 450D is notably larger (19 percent) than the Canon 400D. However, the 450D is markedly lighter (6 percent) than the 400D. In this context, it is worth noting that neither the 400D nor the 450D 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 400D gets 370 shots out of its NB-2LH battery, while the 450D can take 500 images on a single charge of its LP-E5 power pack.

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, just use the right or left arrows in the table to switch to the respective camera. Alternatively, you can also navigate to the CAM-parator app and make your selection from the full list of cameras there.

The price is, of course, an important factor in any camera decision. 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 two cameras under review were launched at the same price and fall into the same market segment. 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: Canon 400D vs Canon 450D

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. 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.

Both cameras under consideration feature an APS-C sensor and have a format factor (sometimes also referred to as "crop factor") of 1.6. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the 450D uses a more advanced image processing engine (DIGIC 3) than the 400D (DIGIC II), with benefits for noise reduction, color accuracy, and processing speed.

Canon 400D and Canon 450D sensor measures

While the two cameras under review share the same sensor size, the 450D offers a higher resolution of 12.2 megapixel, compared with 10.1 MP of the 400D. This megapixel advantage translates into a 10 percent gain in linear resolution. On the other hand, these sensor specs imply that the 450D has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 5.19μm versus 5.71μm for the 400D). However, it should be noted that the 450D is a somewhat more recent model (by 1 year and 5 months) than the 400D, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

400D versus 450D MP

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 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.

The 450D offers Live View, so that it can project the live image that the sensor receives onto the rear screen for framing. The 400D lacks this capability. Both cameras are still-image focused and cannot record videos.
 

Feature comparison: Canon 400D vs Canon 450D

Beyond body and sensor, cameras can and do differ across a range of features. The 400D and the 450D 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 table below summarizes some of the other core capabilities of the Canon 400D and Canon 450D in connection with corresponding information for a sample of similar cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the 400D and the 450D have been discontinued, but can regularly be found used on eBay. The 400D was replaced by the Canon 450D, while the 450D was followed by the Canon 500D.

Review summary: Canon 400D vs Canon 450D

So what is the bottom line? Is there a clear favorite between the Canon 400D and the Canon 450D? A synthesis of the relative strong points of each of the models is listed below.


Advantages of the Canon EOS 400D:

  • More compact: Is smaller (127x84mm vs 129x98mm) and thus needs less room in the bag.
  • More heavily discounted: Has been on the market for longer (launched in August 2006).


Reasons to prefer the Canon EOS 450D:

  • More detail: Has more megapixels (12.2 vs 10.1MP), which boosts linear resolution by 10%.
  • Better jpgs: Has a more modern image processing engine (DIGIC 3 vs DIGIC II).
  • 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.
  • Longer lasting: Gets more shots (500 versus 370) out of a single battery charge.
  • More modern: Was introduced somewhat (1 year and 5 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the 450D is the clear winner of the contest (6 : 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.

400D 02:06 450D

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 400D or the 450D. 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 why hands-on reviews by experts are important.

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. 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.
