Canon 400D versus Canon 650D

The Canon EOS 400D (called Canon XTi in some regions) and the Canon EOS 650D (labelled Canon T4i in some countries) are two digital cameras that were revealed to the public, respectively, in August 2006 and June 2012. 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 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 400D vs Canon 650D

An illustration of the physical size and weight of the Canon 400D and the Canon 650D 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 measures 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 400D – 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 (25 percent) than the Canon 400D. Moreover, the 650D is slightly heavier (3 percent) than the 400D. In this context, it is worth noting that neither the 400D 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 400D gets 370 shots out of its NB-2LH 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.

Any camera purchase 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 400D 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.

 

Sensor comparison: Canon 400D 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. 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 tend to be more expensive and 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.

Technology-wise, the 650D uses a more advanced image processing engine (DIGIC 5) than the 400D (DIGIC II), with benefits for noise reduction, color accuracy, and processing speed.

Canon 400D and Canon 650D sensor measures

With 17.9MP, the 650D offers a higher resolution than the 400D (10.1MP), but the 650D has smaller individual pixels (pixel pitch of 4.31μm versus 5.71μm for the 400D). Yet, the 650D is a much more recent model (by 5 years and 9 months) than the 400D, 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.

400D versus 650D MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. The 650D indeed provides for movie recording, while the 400D does not. The highest resolution format that the 650D can use is 1080/30p.

 

Feature comparison: Canon 400D vs Canon 650D

Apart from body and sensor, cameras can and do differ across a range of features. The 400D 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 following table reports on some other key feature differences and similarities of the Canon 400D, the Canon 650D, and comparable cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Review summary: Canon 400D vs Canon 650D

So what is the bottom line? Is the Canon 400D better than the Canon 650D or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Reasons to prefer the Canon EOS 400D:

  • More compact: Is smaller (127x84mm vs 133x100mm) and thus needs less room in the bag.
  • More heavily discounted: Has been available for much longer (launched in August 2006).


Arguments in favor of the Canon EOS 650D:

  • More detail: Has more megapixels (17.9 vs 10.1MP), which boosts linear resolution by 33%.
  • Better jpgs: Has a more modern image processing engine (DIGIC 5 vs DIGIC II).
  • 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.
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
  • 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 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (440 versus 370) out of a single battery charge.
  • More modern: Reflects 5 years and 9 months of technical progress since the 400D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 650D is the clear winner of the contest (11 : 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.

400D 02:11 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 400D 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 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 (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
