Canon XTi vs Olympus E-500

The Canon EOS Rebel XTi (called Canon 400D in some regions) and the Olympus Evolt E-500 are two digital cameras that were officially introduced, respectively, in August 2006 and September 2005. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (XTi) and a Four Thirds (E-500) sensor. The Canon has a resolution of 10.1 megapixels, whereas the Olympus provides 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 XTi and the Olympus Evolt E-500? 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 XTi and the Olympus E-500 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 dimensions are rounded to the nearest millimeter.

Size Canon XTi vs Olympus E-500
Compare XTi versus E-500 top
Comparison XTi or E-500 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-500 is notably larger (16 percent) than the Canon XTi. However, the E-500 is markedly lighter (14 percent) than the XTi. In this context, it is worth noting that neither the XTi nor the E-500 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 (XTi) and the Four Thirds Lens Catalog (E-500).

Concerning battery life, the XTi gets 370 shots out of its NB-2LH battery, while the E-500 can take 750 images on a single charge of its BLM-1 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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 E-500 was launched at a somewhat lower price (by 25 percent) than the XTi, 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.

Sensor comparison

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

Of the two cameras under consideration, the Canon XTi features an APS-C sensor and the Olympus E-500 a Four Thirds sensor. The sensor area in the E-500 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 XTi has a native 3:2 aspect ratio, while the one in the E-500 offers a 4:3 aspect.

Canon XTi and Olympus E-500 sensor measures

With 10.1MP, the XTi offers a higher resolution than the E-500 (8MP), but the XTi nevertheless has larger individual pixels (pixel pitch of 5.71μm versus 5.30μm for the E-500) due to its larger sensor. Moreover, the XTi is a somewhat more recent model (by 10 months) than the E-500, 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 XTi implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the XTi for good quality output (200 dots per inch) amounts to 19.4 x 13 inches or 49.4 x 32.9 cm, for very good quality (250 dpi) 15.6 x 10.4 inches or 39.5 x 26.3 cm, and for excellent quality (300 dpi) 13 x 8.6 inches or 32.9 x 21.9 cm. The corresponding values for the Olympus E-500 are 16.3 x 12.2 inches or 41.5 x 31.1 cm for good quality, 13.1 x 9.8 inches or 33.2 x 24.9 cm for very good quality, and 10.9 x 8.2 inches or 27.6 x 20.7 cm for excellent quality prints.

The Canon EOS Rebel XTi has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Olympus Evolt E-500 are ISO 100 to ISO 400, with the possibility to increase the ISO range to 100-1600.

XTi versus E-500 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Neither the XTi nor the E-500 offer Live View, so that they cannot project the live image that the sensor receives onto the rear screen. Moreover, both cameras are still-image focused and cannot record videos.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The XTi and the E-500 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 XTi has a higher magnification than the one of the E-500 (0.49x vs 0.45x), 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 XTi and Olympus E-500 along with similar information for a selection of comparators.

The XTi writes its imaging data to Compact Flash cards, while the E-500 uses Compact Flash or xD Picture cards. The E-500 features dual card slots, which can be very useful in case a memory card fails. In contrast, the XTi 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 XTi and Olympus Evolt E-500 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the XTi and the E-500 have been discontinued, but can regularly be found used on eBay. The E-500 was replaced by the Olympus E-510, while the XTi was followed by the Canon Xsi. 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.

Review summary

So what is the bottom line? Which of the two cameras – the Canon XTi or the Olympus E-500 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

ilogo

Advantages of the Canon EOS Rebel XTi:

  • More detail: Offers more megapixels (10.1 vs 8MP) with a 15% 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.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.49x vs 0.45x).
  • Faster burst: Shoots at higher frequency (3 vs 2.5 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (127x84mm vs 130x95mm) and thus needs less room in the bag.
  • More modern: Is somewhat more recent (announced 10 months after the E-500).

ilogo

Arguments in favor of the Olympus Evolt E-500:

  • Less heavy: Has a lower weight (by 77g or 14 percent) and is thus easier to take along.
  • Longer lasting: Gets more shots (750 versus 370) 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 affordable: Was released into a lower priced segment (25 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in September 2005).

If the count of relative strengths (bullet points above) is taken as a measure, the XTi is the clear winner of the match-up (9 : 5 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 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.

XTi 09:05 E-500

How about other alternatives? Do the specifications of the Canon XTi and the Olympus E-500 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the XTi or the E-500. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is where reviews by experts come in. 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
