Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX1 IS and the Canon EOS Rebel T3? 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 SX1 and the Canon T3 is provided in the side-by-side display below. 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 T3 is notably larger (15 percent) than the Canon SX1. In this context, it is worth noting that neither the SX1 nor the T3 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX1 has a lens built in, whereas the T3 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the T3 and their specifications 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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon SX1 features a 1/2.3-inch sensor and the Canon T3 an APS-C sensor. The sensor area in the T3 is 1054 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.6. The sensor in the SX1 has a native 4:3 aspect ratio, while the one in the T3 offers a 3:2 aspect.

With 12.2MP, the T3 offers a higher resolution than the SX1 (10MP), but the T3 nevertheless has larger individual pixels (pixel pitch of 5.15μm versus 1.67μm for the SX1) due to its larger sensor. Moreover, the T3 is a much more recent model (by 2 years and 4 months) than the SX1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the SX1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon T3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T3 for good quality output (200 dots per inch) amounts to 21.4 x 14.2 inches or 54.3 x 36.2 cm, for very good quality (250 dpi) 17.1 x 11.4 inches or 43.4 x 28.9 cm, and for excellent quality (300 dpi) 14.2 x 9.5 inches or 36.2 x 24.1 cm. The corresponding values for the Canon SX1 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.

The Canon PowerShot SX1 IS has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Canon EOS Rebel T3 are ISO 100 to ISO 6400 (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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the SX1 provides a higher video resolution than the T3. It can shoot video footage at 1080/30p, while the T3 is limited to 720/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the SX1 has an electronic viewfinder (202k dots), while the T3 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The adjacent table lists some of the other core features of the Canon SX1 and Canon T3 along with similar information for a selection of comparators.

Both the SX1 and the T3 have been discontinued, but can regularly be found used on ebay. The T3 was replaced by the Canon T5, while the SX1 does not have a direct successor. Further information on the features and operation of the SX1 and T3 can be found, respectively, in the Canon SX1 Manual (free pdf) or the online Canon T3 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Canon SX1 and the Canon T3? Which camera is better? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Canon PowerShot SX1 IS:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better video: Provides higher definition movie capture (1080/30p vs 720/30p).
• More framing info: Has an electronic viewfinder that displays shooting data.
• Larger screen: Has a bigger rear LCD (2.8" vs 2.7") for image review and settings control.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Faster burst: Shoots at higher frequency (4 vs 3 flaps/sec) to capture the decisive moment.
• Ready to shoot: Comes with a built-in lens, while the T3 requires a separate lens.
• More compact: Is smaller (128x88mm vs 130x100mm) and thus needs less room in the bag.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• More heavily discounted: Has been available for much longer (launched in September 2008).

Advantages of the Canon EOS Rebel T3:

• More detail: Has more megapixels (12.2 vs 10MP), which boosts linear resolution by 13%.
• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Is equipped with a larger and more technologically advanced sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/3200s) to freeze action.
• More flexible: Makes it possible to change lenses and thus to use specialty optics.
• More modern: Reflects 2 years and 4 months of technical progress since the SX1 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the match-up finishes in a tie (10 points each). 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. 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.

How about other alternatives? Do the specifications of the Canon SX1 and the Canon T3 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best DSLR Camera listings 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 incomplete and does no justice, for example, to the way the SX1 or the T3 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.

Expert reviews

This is where reviews by experts come in. 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 were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
