Canon 550D vs T1i

The Canon EOS 550D (called Canon T2i in some regions) and the Canon EOS Rebel T1i (labelled Canon 500D in some countries) are two digital cameras that were officially introduced, respectively, in February 2010 and March 2009. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 550D has a resolution of 17.9 megapixels, whereas the T1i provides 15.1 MP.

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 550D 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

An illustration of the physical size and weight of the Canon 550D and the Canon T1i is provided in the side-by-side display below. The two cameras are presented according to their relative size. 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.

Size Canon 550D vs Canon T1i
Compare 550D versus T1i top
Comparison 550D or T1i rear

In this particular case, the Canon 550D and the Canon T1i have exactly the same width and height, and, thus, have identically-sized bodies. However, the T1i is slightly lighter (2 percent) than the 550D. In this context, it is worth noting that neither the 550D 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.

Concerning battery life, the 550D gets 440 shots out of its LP-E8 battery, while the T1i can take 400 images on a single charge of its LP-E5 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. 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 550D was launched at a somewhat lower price (by 13 percent) than the T1i, which makes it more attractive for photographers on a tight budget. 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 sensor inside a digital camera is one of the key determinants 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 and have a format factor (sometimes also referred to as "crop factor") of 1.6. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 550D and Canon T1i sensor measures

While the two cameras under review share the same sensor size, the 550D offers a higher resolution of 17.9 megapixels, compared with 15.1 MP of the T1i. This megapixels advantage translates into a 9 percent gain in linear resolution. On the other hand, these sensor specs imply that the 550D has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.31μm versus 4.69μm for the T1i). In this context, it should be noted, however, that the 550D is a somewhat more recent model (by 10 months) than the T1i, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

The resolution advantage of the Canon 550D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 550D 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 T1i are 23.8 x 15.8 inches or 60.4 x 40.2 cm for good quality, 19 x 12.7 inches or 48.3 x 32.2 cm for very good quality, and 15.8 x 10.6 inches or 40.2 x 26.8 cm for excellent quality prints.

The Canon EOS 550D has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. The Canon EOS Rebel T1i offers exactly the same ISO settings.

550D versus T1i MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the 550D provides a higher frame rate than the T1i. It can shoot video footage at 1080/30p, while the T1i is limited to 1080/20p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 550D 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 adjacent table lists some of the other core features of the Canon 550D and Canon T1i along with similar information for a selection of comparators.

It is notable that the 550D has a microphone port, which is missing on the T1i. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Both the 550D and the T1i have been discontinued, but can regularly be found used on eBay. The T1i was replaced by the Canon T2i, while the 550D was followed by the Canon 600D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.

Review summary

So what is the bottom line? Which of the two cameras – the Canon 550D or the Canon T1i – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.


Advantages of the Canon EOS 550D:

  • More detail: Offers more megapixels (17.9 vs 15.1MP) with a 9% higher linear resolution.
  • Better video: Provides higher movie framerates (1080/30p versus 1080/20p).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
  • More affordable: Was introduced into a lower priced segment (13 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 10 months after the T1i).


Arguments in favor of the Canon EOS Rebel T1i:

  • More heavily discounted: Has been on the market for longer (launched in March 2009).

If the number of relative strengths (bullet points above) is taken as a guide, the 550D is the clear winner of the match-up (6 : 1 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

550D 06:01 T1i

How about other alternatives? Do the specifications of the Canon 550D 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 550D or the T1i. 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.

Expert reviews

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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.
