Canon 550D vs Olympus E-1

The Canon EOS 550D (called Canon T2i in some regions) and the Olympus E-1 are two digital cameras that were officially introduced, respectively, in February 2010 and June 2003. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (550D) and a Four Thirds (E-1) sensor. The Canon has a resolution of 17.9 megapixels, whereas the Olympus provides 4.9 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon 550D and the Olympus E-1. 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 width, height and depth dimensions are rounded to the nearest millimeter.

Size Canon 550D vs Olympus E-1
Compare 550D versus E-1 top
Comparison 550D or E-1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-1 is notably larger (16 percent) than the Canon 550D. Moreover, the E-1 is substantially heavier (39 percent) than the 550D. It is noteworthy in this context that the E-1 is splash and dust-proof, while the 550D does not feature any corresponding weather-sealing.

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 (550D) and the Four Thirds Lens Catalog (E-1).

Concerning battery life, the 550D gets 440 shots out of its Canon LP-E8 battery, while the E-1 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.

Note: 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 550D was launched at a markedly lower price (by 59 percent) than the E-1, 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 550D features an APS-C sensor and the Olympus E-1 a Four Thirds sensor. The sensor area in the E-1 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 550D has a native 3:2 aspect ratio, while the one in the E-1 offers a 4:3 aspect.

Canon 550D and Olympus E-1 sensor measures

With 17.9MP, the 550D offers a higher resolution than the E-1 (4.9MP), but the 550D has smaller individual pixels (pixel pitch of 4.31μm versus 6.78μm for the E-1). However, the 550D is a much more recent model (by 6 years and 7 months) than the E-1, 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 550D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 550D 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-1 are 12.8 x 9.6 inches or 32.5 x 24.4 cm for good quality, 10.2 x 7.7 inches or 26 x 19.5 cm for very good quality, and 8.5 x 6.4 inches or 21.7 x 16.3 cm for excellent quality prints.

The Canon EOS 550D 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 E-1 are ISO 100 to ISO 800, with the possibility to increase the ISO range to 100-3200.

In terms of underlying technology, the 550D is build around a CMOS sensor, while the E-1 uses a CCD imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

550D versus E-1 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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").

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 550D and the E-1 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 viewfinder in the E-1 offers a wider field of view (100%) than the one in the 550D (95%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the 550D has a higher magnification (0.54x vs 0.48x), 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 550D and Olympus E-1 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The 550D has one, while the E-1 does not. While the built-in flash of the 550D is not very powerful, it can at times be useful as a fill-in light.

The 550D writes its imaging data to SDXC cards, while the E-1 uses Compact Flash or xD Picture cards. The E-1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 550D only has one slot.

Studio photographers will appreciate that the Olympus E-1 (unlike the 550D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 550D and the E-1 have been discontinued, but can regularly be found used on ebay. The E-1 was replaced by the Olympus E-3, while the 550D was followed by the Canon 600D. Further information on the features and operation of the 550D and E-1 can be found, respectively, in the Canon 550D Manual (free pdf) or the online Olympus E-1 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Canon 550D and the Olympus E-1? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Advantages of the Canon EOS 550D:

  • More detail: Offers more megapixels (17.9 vs 4.9MP) with a 95% 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 0.48x).
  • Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 134k dots).
  • Faster burst: Shoots at higher frequency (3.7 vs 3 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (129x98mm vs 141x104mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 208g or 28 percent) and hence easier to carry around.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced category (59 percent cheaper at launch).
  • More modern: Reflects 6 years and 7 months of technical progress since the E-1 launch.

ilogo

Arguments in favor of the Olympus E-1:

  • More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Longer lasting: Gets more shots (750 versus 440) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • 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 June 2003).

If the count of relative strengths (bullet points above) is taken as a measure, the 550D is the clear winner of the match-up (15 : 7 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

550D 15:07 E-1

How about other alternatives? Do the specifications of the Canon 550D and the Olympus E-1 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 says little about, for example, the shooting experience and imaging performance of the 550D and the E-1 in practical situations. 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 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.

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

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
