Canon 450D versus Canon 650D

The Canon EOS 450D (called Canon XSi in some regions) and the Canon EOS 650D (labelled Canon T4i in some countries) are two digital cameras that were announced, respectively, in January 2008 and June 2012. 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 650D provides 17.9 MP.

Body comparison

An illustration of the physical size and weight of the Canon 450D and the Canon 650D is provided in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All size 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 side – the 450D – represents the basis for the calculations 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 650D is considerably larger (105 percent) than the Canon 450D. Moreover, the 650D is markedly heavier (10 percent) than the 450D. In this context, it is worth noting that neither the 450D nor the 650D 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.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 450D was somewhat cheaper (by 6 percent) than the 650D at launch, but both cameras fall into the same price category. 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the 650D 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.

Sensor size

With 17.9MP, the 650D offers a higher resolution than the 450D (12.2MP), but the 650D has smaller individual pixels (pixel pitch of 4.31μm versus 5.19μm for the 450D). Yet, the 650D is a much more recent model (by 4 years and 4 months) than the 450D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

Sensor resolution

For most cameras, data on sensor performance has been reported by DXO Mark. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The 650D indeed provides for movie recording, while the 450D does not. The highest resolution format that the 650D can use is 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 450D and the 650D 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 adjacent table lists some of the other core features of the Canon 450D and Canon 650D along with similar information for a selection of comparators. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the 450D and the 650D have been discontinued, but can regularly be found used on ebay. The 450D was replaced by the Canon 500D, while the 650D was followed by the Canon 700D.

Summary

So how do things add up? Which of the two cameras – the Canon 450D or the Canon 650D – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Canon EOS 450D:

  • More compact: Is smaller (129x98mm vs 133x100mm) and thus needs less room in the bag.
  • Longer lasting: Can take more shots (500 versus 440) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in January 2008).

Arguments in favor of the Canon EOS 650D:

  • More detail: Has more megapixels (17.9 vs 12.2MP), which boosts linear resolution by 21%.
  • Broader imaging potential: Can capture not only stills but also 1080/30p video.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (5 vs 3.5 flaps/sec) to capture the decisive moment.
  • More modern: Reflects 4 years and 4 months of technical progress since the 450D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 650D is the clear winner of the contest (7 : 3 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs.

450D 03:07 650D

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the 450D and the 650D in practical situations. 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 why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The review scores listed above should be treated with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. 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.
