Canon T3 vs Olympus E-450
The Canon EOS Rebel T3 (called Canon 1100D in some regions) and the Olympus E-450 are two digital cameras that were announced, respectively, in February 2011 and March 2009. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (T3) and a Four Thirds (E-450) 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-450? 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 Olympus E-450 are illustrated 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 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 Olympus E-450 is notably smaller (9 percent) than the Canon T3. Moreover, the E-450 is markedly lighter (11 percent) than the T3. In this context, it is worth noting that neither the T3 nor the E-450 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-450).
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The T3 was somewhat cheaper (by 10 percent) than the E-450 at launch, but both cameras fall into the same price category. 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 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 T3 features an APS-C sensor and the Olympus E-450 a Four Thirds sensor. The sensor area in the E-450 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-450 offers a 4:3 aspect.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 12.2MP, the T3 offers a higher resolution than the E-450 (10MP), but the T3 nevertheless has larger individual pixels (pixel pitch of 5.15μm versus 4.74μm for the E-450) due to its larger sensor. Moreover, the T3 is a somewhat more recent model (by 1 year and 10 months) than the E-450, and its sensor might 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-450 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-450 are ISO 100 to ISO 1600 (no boost).
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. Of the two cameras under review, the T3 has a notably higher overall DXO score than the E-450 (overall score 6 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.4 bits higher color depth, 0.5 EV in additional dynamic range, and 0.6 stops in additional low light sensitivity. 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 also of capturing video footage. The T3 indeed provides movie recording capabilities, while the E-450 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 variety of features. The T3 and the E-450 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-450 (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 table below summarizes some of the other core capabilities of the Canon T3 and Olympus E-450 in connection with corresponding information for a sample of similar cameras.

The T3 writes its imaging data to SDXC cards, while the E-450 uses Compact Flash or xD Picture cards. The E-450 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-450 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the T3 and the E-450 have been discontinued, but can regularly be found used on eBay. The T3 was replaced by the Canon T5, while the E-450 does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Olympus websites.
So what is the bottom line? Which of the two cameras – the Canon T3 or the Olympus E-450 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Advantages of 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 (6 points) in the DXO overall assessment.
- Better low-light sensitivity: Requires less light for good images (0.6 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).
- Longer lasting: Can take more shots (700 versus 500) on a single battery charge.
- More modern: Is somewhat more recent (announced 1 year and 10 months after the E-450).
Reasons to prefer the Olympus E-450:
- Faster burst: Shoots at higher frequency (3.5 vs 3 flaps/sec) to capture the decisive moment.
- Less heavy: Has a lower weight (by 55g or 11 percent) and is thus easier to take along.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More heavily discounted: Has been on the market for longer (launched in March 2009).
If the count of individual advantages (bullet points above) is taken as a guide, the T3 emerges as the winner of the contest (7 : 4 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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 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-450. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

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 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.
