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 officially introduced, 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. 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 650D

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. The two cameras are presented according to their relative size. 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 toggle the display 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 notably larger (5 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.

Concerning battery life, the 450D gets 500 shots out of its LP-E5 battery, while the 650D can take 440 images on a single charge of its LP-E8 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The 450D was somewhat cheaper (by 6 percent) than the 650D at launch, but both cameras fall into the same price category. 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 650D

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 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.

Technology-wise, the 650D uses a more advanced image processing engine (DIGIC 5) than the 450D (DIGIC 3), with benefits for noise reduction, color accuracy, and processing speed.

Canon 450D and Canon 650D sensor measures

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.

The 650D has on-sensor phase detect pixels, which results in relatively fast and reliable autofocus acquisition during video recording.

450D versus 650D MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-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: Canon 450D vs Canon 650D

Apart from 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 table below summarizes some of the other core capabilities of the Canon 450D and Canon 650D in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or in the dpreview camera hub.

Review summary: Canon 450D vs Canon 650D

So what conclusions can be drawn? Which of the two cameras – the Canon 450D or the Canon 650D – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.


Reasons to prefer the Canon EOS 450D:

  • 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).


Advantages of the Canon EOS 650D:

  • More detail: Has more megapixels (17.9 vs 12.2MP), which boosts linear resolution by 21%.
  • Better jpgs: Has a more modern image processing engine (DIGIC 5 vs DIGIC 3).
  • Broader imaging potential: Can capture not only stills but also 1080/30p video.
  • Better video autofocus: Features on-sensor phase-detection for more confident movie autofocus.
  • 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 count of relative strengths (bullet points above) is taken as a measure, the 650D is the clear winner of the contest (9 : 2 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 before making a camera decision.

450D 02:09 650D

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 450D or the 650D. 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 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
