Canon T3 vs Olympus E-520
The Canon EOS Rebel T3 (called Canon 1100D in some regions) and the Olympus E-520 are two digital cameras that were revealed to the public, respectively, in February 2011 and May 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (T3) and a Four Thirds (E-520) sensor. The Canon has a resolution of 12.2 megapixels, whereas the Olympus provides 10 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 Olympus E-520? 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.
An illustration of the physical size and weight of the Canon T3 and the Olympus E-520 is provided 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 width, height and depth measures 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 Olympus E-520 is somewhat smaller (4 percent) than the Canon T3. However, the E-520 is markedly heavier (8 percent) than the T3. In this context, it is worth noting that neither the T3 nor the E-520 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (T3) and the Four Thirds Lens Catalog (E-520).
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. The T3 was launched at a markedly lower price (by 36 percent) than the E-520, which puts it into a different 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.
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 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. 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon T3 features an APS-C sensor and the Olympus E-520 a Four Thirds sensor. The sensor area in the E-520 is 30 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.0. The sensor in the T3 has a native 3:2 aspect ratio, while the one in the E-520 offers a 4:3 aspect.
With 12.2MP, the T3 offers a higher resolution than the E-520 (10MP), but the T3 nevertheless has larger individual pixels (pixel pitch of 5.15μm versus 4.74μm for the E-520) due to its larger sensor. Moreover, the T3 is a much more recent model (by 2 years and 8 months) than the E-520, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
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 Olympus E-520 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 EOS Rebel T3 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Olympus E-520 are ISO 100 to ISO 1600 (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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). Of the two cameras under review, the T3 has a notably higher overall DXO score than the E-520 (overall score 7 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.5 bits higher color depth, 0.6 EV in additional dynamic range, and 0.5 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. The T3 indeed provides movie recording capabilities, while the E-520 does not. The highest resolution format that the T3 can use is 720/30p.
Apart from body and sensor, cameras can and do differ across a range of features. The T3 and the E-520 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 T3 has a higher magnification than the one of the E-520 (0.50x vs 0.46x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon T3, the Olympus E-520, and comparable cameras.

One feature that differentiates the E-520 and the T3 is in-body image stabilization (IBIS). The E-520 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 E-520 uses Compact Flash or xD Picture cards. The E-520 features dual card slots, which can be very useful in case a memory card fails. In contrast, the T3 only has one slot.
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 Olympus E-520 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the T3 and the E-520 have been discontinued, but can regularly be found used on ebay. The T3 was replaced by the Canon T5, while the E-520 does not have a direct successor. Further information on the features and operation of the T3 and E-520 can be found, respectively, in the Canon T3 Manual (free pdf) or the online Olympus E-520 Manual.
So what is the bottom line? Is the Canon T3 better than the Olympus E-520 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Canon EOS Rebel T3:
- More detail: Offers more megapixels (12.2 vs 10MP) with a 13% higher linear resolution.
- Better image quality: Scores markedly higher (7 points) in the DXO overall assessment.
- More dynamic range: Captures a larger spectrum of light and dark details (0.6 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (0.5 stops ISO advantage).
- Broader imaging potential: Can record not only still images but also 720/30p movies.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.50x vs 0.46x).
- More affordable: Was introduced into a lower priced category (36 percent cheaper at launch).
- More modern: Reflects 2 years and 8 months of technical progress since the E-520 launch.
Arguments in favor of the Olympus E-520:
- Faster burst: Shoots at higher frequency (3.5 vs 3 flaps/sec) to capture the decisive moment.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More heavily discounted: Has been around for much longer (launched in May 2008).
If the count of individual advantages (bullet points above) is taken as a guide, the T3 is the clear winner of the match-up (8 : 4 points). 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 T3 and the Olympus E-520 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the T3 or the E-520. 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 why expert reviews are important. 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.

The review scores listed above should be treated 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
