Canon 4000D versus Canon 400D

The Canon EOS 4000D and the Canon EOS 400D (labelled Canon XTi in some countries) are two digital cameras that were announced, respectively, in February 2018 and August 2006. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 4000D has a resolution of 17.9 megapixel, whereas the 400D provides 10.1 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 4000D vs Canon 400D

The side-by-side display below illustrates the physical size and weight of the Canon 4000D and the Canon 400D. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth 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 – the 4000D – 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 400D is notably smaller (19 percent) than the Canon 4000D. However, the 400D is markedly heavier (28 percent) than the 4000D. In this context, it is worth noting that neither the 4000D nor the 400D 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 4000D gets 500 shots out of its LP-E10 battery, while the 400D can take 370 images on a single charge of its NB-2LH power pack.

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 camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 4000D was launched at a markedly lower price (by 50 percent) than the 400D, 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: Canon 4000D vs Canon 400D

The size of the imaging sensor is a crucial determinant 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. 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 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 400D is 1 percent smaller. 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 4000D offers a higher resolution than the 400D (10.1MP), but the 4000D has smaller individual pixels (pixel pitch of 4.31μm versus 5.71μm for the 400D). However, the 4000D is a somewhat more recent model (by 11 years and 6 months) than the 400D, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

Many modern cameras cannot only take still pictures, but also record videos. The 4000D indeed provides movie recording capabilities, while the 400D does not. The highest resolution format that the 4000D can use is 1080/30p.

Feature comparison: Canon 4000D vs Canon 400D

Apart from body and sensor, cameras can and do differ across a variety of features. The 4000D and the 400D 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 4000D, the Canon 400D, and comparable cameras.

The 4000D is a current model that online retailers, such as amazon, will have in stock. In contrast, the 400D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 400D was succeeded by the Canon 450D.

Review summary: Canon 4000D vs Canon 400D

So what is the bottom line? Is the Canon 4000D better than the Canon 400D or vice versa? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Canon EOS 4000D:

  • More detail: Offers more megapixels (17.9 vs 10.1MP) with a 33% higher linear resolution.
  • Broader imaging potential: Can record not only still images but also 1080/30p movies.
  • Larger screen: Has a bigger rear LCD (2.7" vs 2.5") for image review and settings control.
  • Less heavy: Is lighter (by 120g or 22 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (500 versus 370) on a single battery charge.
  • More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
  • More modern: Reflects 11 years and 6 months of technical progress since the 400D launch.

Reasons to prefer the Canon EOS 400D:

  • More compact: Is smaller (127x84mm vs 129x102mm) and will fit more readily into a bag.
  • More heavily discounted: Has been around for much longer (launched in August 2006).

If the number of relative strengths (bullet points above) is taken as a guide, the 4000D is the clear winner of the match-up (7 : 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.

4000D 07:02 400D

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 4000D or the 400D handle or perform in practice. 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 expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
