Canon T2i vs Olympus E-330

The Canon EOS Rebel T2i (called Canon 550D in some regions) and the Olympus Evolt E-330 are two digital cameras that were announced, respectively, in February 2010 and January 2006. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (T2i) and a Four Thirds (E-330) sensor. The Canon has a resolution of 17.9 megapixels, whereas the Olympus provides 7.4 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 T2i and the Olympus Evolt E-330? 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

The side-by-side display below illustrates the physical size and weight of the Canon T2i and the Olympus E-330. 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 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-330 is somewhat smaller (4 percent) than the Canon T2i. However, the E-330 is markedly heavier (20 percent) than the T2i. In this context, it is worth noting that neither the T2i nor the E-330 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 (T2i) and the Four Thirds Lens Catalog (E-330).

Concerning battery life, the T2i gets 440 shots out of its Canon LP-E8 battery, while the E-330 can take 750 images on a single charge of its Olympus BLM-1 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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 T2i was launched at a markedly lower price (by 30 percent) than the E-330, which puts it into a different market segment. 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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.

Of the two cameras under consideration, the Canon T2i features an APS-C sensor and the Olympus E-330 a Four Thirds sensor. The sensor area in the E-330 is 32 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 T2i has a native 3:2 aspect ratio, while the one in the E-330 offers a 4:3 aspect.

With 17.9MP, the T2i offers a higher resolution than the E-330 (7.4MP), but the T2i has smaller individual pixels (pixel pitch of 4.31μm versus 5.51μm for the E-330). However, the T2i is a much more recent model (by 4 years) than the E-330, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

The resolution advantage of the Canon T2i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T2i 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 Olympus E-330 are 15.7 x 11.8 inches or 39.8 x 29.9 cm for good quality, 12.5 x 9.4 inches or 31.9 x 23.9 cm for very good quality, and 10.5 x 7.8 inches or 26.6 x 19.9 cm for excellent quality prints.

The Canon EOS Rebel T2i has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Olympus Evolt E-330 are ISO 100 to ISO 400, with the possibility to increase the ISO range to 100-1600.

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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 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 are not only capable of taking still images, but also of capturing video footage. The T2i indeed provides movie recording capabilities, while the E-330 does not. The highest resolution format that the T2i can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The T2i and the E-330 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 T2i has a higher magnification than the one of the E-330 (0.54x vs 0.47x), 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 T2i, the Olympus E-330, and comparable cameras.

The T2i writes its imaging data to SDXC cards, while the E-330 uses Compact Flash or xD Picture cards. The E-330 features dual card slots, which can be very useful in case a memory card fails. In contrast, the T2i only has one slot.

Connectivity comparison

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 T2i and Olympus Evolt E-330 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the T2i and the E-330 have been discontinued, but can regularly be found used on ebay. The T2i was replaced by the Canon T3i, while the E-330 does not have a direct successor. Further information on the features and operation of the T2i and E-330 can be found, respectively, in the Canon T2i Manual (free pdf) or the online Olympus E-330 Manual.

Review summary

So how do things add up? Is the Canon T2i better than the Olympus E-330 or vice versa? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Canon EOS Rebel T2i:

• More detail: Offers more megapixels (17.9 vs 7.4MP) with a 59% higher linear resolution.
• Better image quality: Features a larger and more technologically advanced imaging 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.
• Broader imaging potential: Can record not only still images but also 1080/30p movies.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.54x vs 0.47x).
• Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 215k dots).
• Faster burst: Shoots at higher frequency (3.7 vs 3 flaps/sec) to capture the decisive moment.
• Less heavy: Is lighter (by 107g or 17 percent) and hence easier to carry around.
• More affordable: Was introduced into a lower priced category (30 percent cheaper at launch).
• More modern: Reflects 4 years of technical progress since the E-330 launch.

Arguments in favor of the Olympus Evolt E-330:

• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Longer lasting: Gets more shots (750 versus 440) out of a single battery charge.
• 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 January 2006).

If the count of relative strengths (bullet points above) is taken as a measure, the T2i is the clear winner of the match-up (13 : 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 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 T2i and the Olympus E-330 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the T2i or the E-330. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is why hands-on reviews by experts 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], 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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
