Canon T3 vs Sony A58
The Canon EOS Rebel T3 (called Canon 1100D in some regions) and the Sony Alpha SLT-A58 are two digital cameras that were announced, respectively, in February 2011 and February 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The Canon has a resolution of 12.2 megapixels, whereas the Sony provides 19.8 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 Rebel T3 and the Sony Alpha SLT-A58? 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 physical size and weight of the Canon T3 and the Sony A58 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A58 is notably smaller (6 percent) than the Canon T3. Moreover, the A58 is slightly lighter (1 percent) than the T3. In this context, it is worth noting that neither the T3 nor the A58 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
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.

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 T3 was launched at a somewhat lower price (by 25 percent) than the A58, 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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, but their sensors differ slightly in size. The sensor area in the A58 is 14 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (T3) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 19.8MP, the A58 offers a higher resolution than the T3 (12.2MP), but the A58 has smaller individual pixels (pixel pitch of 4.31μm versus 5.15μm for the T3). Yet, the A58 is a much more recent model (by 2 years) than the T3, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Sony A58 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A58 for good quality output (200 dots per inch) amounts to 27.3 x 18.2 inches or 69.3 x 46.1 cm, for very good quality (250 dpi) 21.8 x 14.5 inches or 55.4 x 36.9 cm, and for excellent quality (300 dpi) 18.2 x 12.1 inches or 46.2 x 30.8 cm. The corresponding values for the Canon T3 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 T3 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Sony Alpha SLT-A58 are ISO 100 to ISO 16000, with the possibility to increase the ISO range to 100-25600.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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. Of the two cameras under consideration, the A58 offers substantially better image quality than the T3 (overall score 12 points higher). The advantage is based on 1.4 bits higher color depth, 1.5 EV in additional dynamic range, and 0 stops of reduced low light sensitivity. 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 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 A58 provides a better video resolution than the T3. It can shoot movie footage at 1080/60i, while the Canon is limited to 720/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A58 has an electronic viewfinder (1440k 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 viewfinder in the A58 offers a wider field of view (100%) than the one in the T3 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the A58 has a higher magnification (0.57x 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 T3 and Sony A58 along with similar information for a selection of comparators.

One feature that differentiates the A58 and the T3 is in-body image stabilization (IBIS). The A58 reduces the risk of handshake-induced blur with all attached lenses, while the T3 offers no blur reduction with lenses that themselves do not provide optical image stabilization.
The T3 writes its imaging data to SDXC cards, while the A58 uses SDXC or Memory Stick PRO Duo 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 Rebel T3 and Sony Alpha SLT-A58 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A58 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The T3 does not feature such a mic input.
Both the T3 and the A58 have been discontinued, but can regularly be found used on eBay. The T3 was replaced by the Canon T5, while the A58 was followed by the Sony A68. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Sony websites.
So what conclusions can be drawn? Is there a clear favorite between the Canon T3 and the Sony A58? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon EOS Rebel T3:
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- More affordable: Was introduced into a lower priced segment (25 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in February 2011).
Advantages of the Sony Alpha SLT-A58:
- More detail: Has more megapixels (19.8 vs 12.2MP), which boosts linear resolution by 28%.
- Better image quality: Scores substantially higher (12 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.4 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (1.5 EV of extra DR).
- Better video: Provides higher definition movie capture (1080/60i vs 720/30p).
- Better sound: Can connect to an external microphone for higher quality sound recording.
- More framing info: Has an electronic viewfinder that displays shooting data.
- More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.57x vs 0.50x).
- More detailed LCD: Has a higher resolution rear screen (460k vs 230k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More modern: Reflects 2 years of technical progress since the T3 launch.
If the count of individual advantages (bullet points above) is taken as a guide, the A58 is the clear winner of the contest (14 : 3 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.

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 T3 and the A58 in practical situations. 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.
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], 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
