Canon XSi vs T1i

The Canon EOS Rebel XSi (called Canon 450D in some regions) and the Canon EOS Rebel T1i (labelled Canon 500D in some countries) are two digital cameras that were revealed to the public, respectively, in January 2008 and March 2009. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The XSi has a resolution of 12.2 megapixels, whereas the T1i provides 15.1 MP.

As their names suggest, both the Canon EOS Rebel XSi and the Canon EOS Rebel T1i belong to Canon's Rebel line of DSLR cameras. This range of APS-C cameras, which started out with the Canon EOS Digital Rebel in 2003, has been a big commercial success and the backbone of Canon's dominance in the digital camera market. The popularity of the Rebel cameras is the result of them inheriting much of the sensor and shooting technology from earlier released professional DSLRs, while being sold at a much more budget-friendly price point. The strong brand reputation of Canon and the comprehensive EOS system of compatible lenses and accessories further contributes to the appeal of the Rebel cams, including the Canon XSi and Canon T1i. 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 Rebel XSi and the Canon EOS Rebel T1i? 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.

Body comparison

The physical size and weight of the Canon XSi and the Canon T1i 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 size dimensions are rounded to the nearest millimeter.

In this particular case, the Canon XSi and the Canon T1i have exactly the same width and height, and, thus, have identically-sized bodies. However, the T1i is slightly lighter (1 percent) than the XSi. In this context, it is worth noting that neither the XSi nor the T1i 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 obviously take relative prices into account. 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 two cameras under review were launched at the same price and fall into the same market segment. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

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. 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 are more costly to manufacture and tend to 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 T1i 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 T1i uses a more advanced image processing engine (DIGIC 4) than the XSi (DIGIC 3), with benefits for noise reduction, color accuracy, and processing speed.

With 15.1MP, the T1i offers a higher resolution than the XSi (12.2MP), but the T1i has smaller individual pixels (pixel pitch of 4.69μm versus 5.19μm for the XSi). Yet, the T1i is a somewhat more recent model (by 1 year and 2 months) than the XSi, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Canon T1i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T1i for good quality output (200 dots per inch) amounts to 23.8 x 15.8 inches or 60.4 x 40.2 cm, for very good quality (250 dpi) 19 x 12.7 inches or 48.3 x 32.2 cm, and for excellent quality (300 dpi) 15.8 x 10.6 inches or 40.2 x 26.8 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 Rebel XSi has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon EOS Rebel T1i are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800.

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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The T1i indeed provides for movie recording, while the XSi does not. The highest resolution format that the T1i can use is 1080/20p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The XSi and the T1i 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%), as well as the same magnification (0.54x). The table below summarizes some of the other core capabilities of the Canon XSi and Canon T1i in connection with corresponding information for a sample of similar cameras.

Both the XSi and the T1i have been discontinued, but can regularly be found used on ebay. The XSi was replaced by the Canon T1i, while the T1i was followed by the Canon T2i. Further information on the features and operation of the XSi and T1i can be found, respectively, in the Canon XSi Manual (free pdf) or the online Canon T1i Manual.

Review summary

So how do things add up? Is the Canon XSi better than the Canon T1i or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Canon EOS Rebel XSi:

• Longer lasting: Can take more shots (500 versus 400) on a single battery charge.
• More heavily discounted: Has been on the market for longer (launched in January 2008).

Advantages of the Canon EOS Rebel T1i:

• More detail: Has more megapixels (15.1 vs 12.2MP), which boosts linear resolution by 11%.
• More dynamic range: Captures a broader range of light and dark details (0.7 EV of extra DR).
• Better jpgs: Has a more modern image processing engine (DIGIC 4 vs DIGIC 3).
• Broader imaging potential: Can capture not only stills but also 1080/20p video.
• More detailed LCD: Has a higher resolution rear screen (920k vs 230k dots).
• More modern: Was introduced somewhat (1 year and 2 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the T1i is the clear winner of the contest (6 : 2 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 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.

How about other alternatives? Do the specifications of the Canon XSi and the Canon T1i 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the XSi or the T1i perform in practice. 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 expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
