Canon 4000D vs XSi

The Canon EOS 4000D (called Canon T100 in some regions) and the Canon EOS Rebel XSi (labelled Canon 450D in some countries) are two digital cameras that were revealed to the public, respectively, in February 2018 and January 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 4000D has a resolution of 17.9 megapixels, whereas the XSi provides 12.2 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

The physical size and weight of the Canon 4000D and the Canon XSi are illustrated in the side-by-side display below. 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 measures are rounded to the nearest millimeter.

Size Canon 4000D vs Canon XSi
Compare 4000D versus XSi top
Comparison 4000D or XSi rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon XSi is somewhat smaller (4 percent) than the Canon 4000D. However, the XSi is markedly heavier (20 percent) than the 4000D. In this context, it is worth noting that neither the 4000D nor the XSi 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 compare the optics available in the Canon EF Lens Catalog.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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 4000D was launched at a markedly lower price (by 50 percent) than the XSi, 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 imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 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 XSi 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.

In terms of chip-set technology, the 4000D uses a more advanced image processing engine (DIGIC 4+) than the XSi (DIGIC 3), with benefits for noise reduction, color accuracy, and processing speed.

Canon 4000D and Canon XSi sensor measures

With 17.9MP, the 4000D offers a higher resolution than the XSi (12.2MP), but the 4000D has smaller individual pixels (pixel pitch of 4.31μm versus 5.19μm for the XSi). However, the 4000D is a much more recent model (by 10 years and 1 month) than the XSi, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

The resolution advantage of the Canon 4000D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 4000D for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Canon XSi are 21.4 x 14.2 inches or 54.3 x 36.2 cm for good quality, 17.1 x 11.4 inches or 43.4 x 28.9 cm for very good quality, and 14.2 x 9.5 inches or 36.2 x 24.1 cm for excellent quality prints.

The Canon EOS 4000D has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Canon EOS Rebel XSi are ISO 100 to ISO 1600 (no boost).

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.

4000D versus XSi 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 imaging performance. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The 4000D and the XSi 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 viewfinders of both cameras offer the same field of view (95%), but the viewfinder of the XSi has a higher magnification than the one of the 4000D (0.54x vs 0.50x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 4000D and Canon XSi in connection with corresponding information for a sample of similar cameras.

It is notable that the 4000D offers wifi support, while the XSi does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

The 4000D is a recent model that features in the current product line-up of Canon. In contrast, the XSi has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the XSi was succeeded by the Canon T1i. Further information on the features and operation of the 4000D and XSi can be found, respectively, in the Canon 4000D Manual (free pdf) or the online Canon XSi Manual.

Review summary

So what conclusions can be drawn? Is the Canon 4000D better than the Canon XSi or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Reasons to prefer the Canon EOS 4000D:

  • More detail: Offers more megapixels (17.9 vs 12.2MP) with a 21% higher linear resolution.
  • More dynamic range: Captures a larger spectrum of light and dark details (0.6 EV of extra DR).
  • Better jpgs: Has a more modern image processing engine (DIGIC 4+ vs DIGIC 3).
  • Broader imaging potential: Can record not only still images but also 1080/30p movies.
  • Less heavy: Is lighter (by 88g or 17 percent) and hence easier to carry around.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
  • More modern: Reflects 10 years and 1 month of technical progress since the XSi launch.


Advantages of the Canon EOS Rebel XSi:

  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.54x vs 0.50x).
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
  • Faster burst: Shoots at higher frequency (3.5 vs 3 flaps/sec) to capture the decisive moment.
  • More heavily discounted: Has been around for much longer (launched in January 2008).

If the count of relative strengths (bullet points above) is taken as a measure, the 4000D is the clear winner of the match-up (9 : 4 points). 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

4000D 09:04 XSi

How about other alternatives? Do the specifications of the Canon 4000D and the Canon XSi 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the 4000D and the XSi 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.

Expert reviews

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
