Canon 1100D vs XSi
The Canon EOS 1100D (called Canon T3 in some regions) and the Canon EOS Rebel XSi (labelled Canon 450D in some countries) are two digital cameras that were announced, respectively, in February 2011 and January 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. Both cameras offer a resolution of 12.2 megapixels.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 1100D and the Canon EOS Rebel XSi? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
The side-by-side display below illustrates the physical size and weight of the Canon 1100D and the Canon XSi. 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 dimensions are rounded to the nearest millimeter.
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 (3 percent) than the Canon 1100D. However, the XSi is markedly heavier (6 percent) than the 1100D. In this context, it is worth noting that neither the 1100D 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 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 1100D was launched at a markedly lower price (by 44 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.
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 2 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.
In terms of chip-set technology, the 1100D uses a more advanced image processing engine (DIGIC 4) than the XSi (DIGIC 3), with benefits for noise reduction, color accuracy, and processing speed.
Even though the XSi has a slightly larger sensor, both cameras offer the same resolution of 12.2 megapixels. This implies that the XSi has a lower pixel density and marginally larger individual pixels (with a pixel pitch of 5.19μm versus 5.15μm for the 1100D), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the 1100D is much more recent (by 3 years) than the XSi, and its sensor will have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.
The Canon EOS 1100D has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Canon EOS Rebel XSi are ISO 100 to ISO 1600 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 are not only capable of taking still images, but also of capturing video footage. The 1100D indeed provides movie recording capabilities, while the XSi does not. The highest resolution format that the 1100D can use is 720/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The 1100D 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 1100D (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 adjacent table lists some of the other core features of the Canon 1100D and Canon XSi along with similar information for a selection of comparators.

The 1100D writes its imaging data to SDXC cards, while the XSi uses SDHC cards.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon EOS 1100D and Canon EOS Rebel XSi and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the 1100D and the XSi have been discontinued, but can regularly be found used on eBay. The XSi was replaced by the Canon T1i, while the 1100D was followed by the Canon 1200D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So how do things add up? Is there a clear favorite between the Canon 1100D and the Canon XSi? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Canon EOS 1100D:
- 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 720/30p movies.
- Longer lasting: Can take more shots (700 versus 500) on a single battery charge.
- More affordable: Was introduced into a lower priced category (44 percent cheaper at launch).
- More modern: Reflects 3 years of technical progress since the XSi launch.
Arguments in favor 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 number of relative strengths (bullet points above) is taken as a guide, the 1100D comes out slightly ahead of the XSi (5 : 4 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the 1100D 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.
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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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.
