Canon 450D vs 5D

The Canon EOS 450D (called Canon XSi in some regions) and the Canon EOS 5D are two digital cameras that were officially introduced, respectively, in January 2008 and August 2005. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (450D) and a full frame (5D) sensor. The 450D has a resolution of 12.2 megapixels, whereas the 5D provides 12.7 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 5D? 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

The side-by-side display below illustrates the physical size and weight of the Canon 450D and the Canon 5D. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. 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 Canon 5D is notably larger (36 percent) than the Canon 450D. Moreover, the 5D is substantially heavier (71 percent) than the 450D. It is noteworthy in this context that the 5D is splash and dust-proof, while the 450D does not feature any corresponding weather-sealing.

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 (as in the 5D) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (450D). You can compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the 450D gets 500 shots out of its Canon LP-E5 battery, while the 5D can take 400 images on a single charge of its Canon BP-511A power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 450D was launched at a markedly lower price (by 76 percent) than the 5D, which puts it into a different 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

The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 450D features an APS-C sensor and the Canon 5D a full frame sensor. The sensor area in the 5D is 163 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

In terms of chip-set technology, the 450D uses a more advanced image processing engine (DIGIC 3) than the 5D (DIGIC 2), with benefits for noise reduction, color accuracy, and processing speed.

With 12.7MP, the 5D offers a higher resolution than the 450D (12.2MP), but the 5D nevertheless has larger individual pixels (pixel pitch of 8.25μm versus 5.19μm for the 450D) due to its larger sensor. However, the 450D is a much more recent model (by 2 years and 5 months) than the 5D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The Canon EOS 450D has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon EOS 5D are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 50-3200.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). Of the two cameras under consideration, the 5D has a markedly higher DXO score than the 450D (overall score 10 points higher), which will translate into better image quality. The advantage is based on 1 bits higher color depth, 0.3 EV in additional dynamic range, and 1 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The 450D and the 5D 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 viewfinder in the 5D offers a wider field of view (96%) than the one in the 450D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 5D has a higher magnification (0.71x vs 0.54x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon 450D and Canon 5D along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The 450D has one, while the 5D does not. While the built-in flash of the 450D is not very powerful, it can at times be useful as a fill-in light.

The 450D writes its imaging data to SDHC cards, while the 5D uses Compact Flash cards.

Connectivity comparison

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 Canon EOS 5D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 5D (unlike the 450D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 450D and the 5D have been discontinued, but can regularly be found used on ebay. The 5D was replaced by the Canon 5D Mark II, while the 450D was followed by the Canon 500D. Further information on the features and operation of the 450D and 5D can be found, respectively, in the Canon 450D Manual (free pdf) or the online Canon 5D Manual.

Review summary

So how do things add up? Is there a clear favorite between the Canon 450D and the Canon 5D? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Canon EOS 450D:

• Better jpgs: Has a more modern image processing engine (DIGIC 3 vs DIGIC 2).
• 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.
• More compact: Is smaller (129x98mm vs 152x113mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 371g or 41 percent) and hence easier to carry around.
• Longer lasting: Can take more shots (500 versus 400) on a single battery charge.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More affordable: Was introduced into a lower priced category (76 percent cheaper at launch).
• More modern: Reflects 2 years and 5 months of technical progress since the 5D launch.

Arguments in favor of the Canon EOS 5D:

• Better image quality: Scores markedly higher (10 points) in the DXO overall evaluation.
• Better low-light sensitivity: Can shoot in dim conditions (1 stops ISO advantage).
• More complete view: Has a viewfinder with a larger field of view (96% vs 95%).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.71x vs 0.54x).
• Easier setting verification: Features a control panel on top to check shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• More heavily discounted: Has been around for much longer (launched in August 2005).

If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (9 points each). 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.

How about other alternatives? Do the specifications of the Canon 450D and the Canon 5D 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 5D 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.

Expert reviews

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], digitalcameraworld [DCW], 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.

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

The above review scores should be interpreted 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
