Canon 50D vs Olympus E-P3

The Canon EOS 50D and the Olympus PEN E-P3 are two enthusiast cameras that were announced, respectively, in August 2008 and June 2011. The 50D is a DSLR, while the E-P3 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (50D) and a Four Thirds (E-P3) sensor. The Canon has a resolution of 15.1 megapixels, whereas the Olympus provides 12.2 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 50D and the Olympus PEN E-P3? 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 50D and the Olympus E-P3. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

The E-P3 can be obtained in three different colors (black, silver, white), while the 50D is only available in black.

Size Canon 50D vs Olympus E-P3
Compare 50D versus E-P3 top
Comparison 50D or E-P3 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-P3 is considerably smaller (47 percent) than the Canon 50D. Moreover, the E-P3 is substantially lighter (55 percent) than the 50D. It is worth mentioning in this context that the 50D is splash and dust resistant, while the E-P3 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 (50D) and the Micro Four Thirds Lens Catalog (E-P3). Mirrorless cameras, such as the E-P3, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the 50D gets 800 shots out of its BP-511A battery, while the E-P3 can take 330 images on a single charge of its BLS-5 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-P3 was launched at a markedly lower price (by 38 percent) than the 50D, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 50D features an APS-C sensor and the Olympus E-P3 a Four Thirds sensor. The sensor area in the E-P3 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 50D has a native 3:2 aspect ratio, while the one in the E-P3 offers a 4:3 aspect.

Canon 50D and Olympus E-P3 sensor measures

With 15.1MP, the 50D offers a higher resolution than the E-P3 (12.2MP), but the 50D nevertheless has larger individual pixels (pixel pitch of 4.69μm versus 4.29μm for the E-P3) due to its larger sensor. However, the E-P3 is a much more recent model (by 2 years and 10 months) than the 50D, 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 50D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 50D for good quality output (200 dots per inch) amounts to 23.8 x 15.8 inch or 60.4 x 40.2 cm, for very good quality (250 dpi) 19 x 12.7 inch or 48.3 x 32.2 cm, and for excellent quality (300 dpi) 15.8 x 10.6 inch or 40.2 x 26.8 cm. The corresponding values for the Olympus E-P3 are 20.2 x 15.1 inch or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inch or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inch or 34.1 x 25.6 cm for excellent quality prints.

The Canon EOS 50D has a native sensitivity range from ISO 100 to ISO 3200, which can be extended to ISO 100-12800. The corresponding ISO settings for the Olympus PEN E-P3 are ISO 200 to ISO 12800 (no boost).

50D versus E-P3 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 50D provides substantially higher image quality than the E-P3, with an overall score that is 12 points higher. This advantage is based on 1 bits higher color depth, 1.3 EV in additional dynamic range, and 0.4 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 E-P3 indeed provides for movie recording, while the 50D does not. The highest resolution format that the E-P3 can use is 1080/60i.

 

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 50D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-P3 relies on live view and the rear LCD for framing. That said, the E-P3 can be equipped with an optional viewfinder – the VF-3. The adjacent table lists some of the other core features of the Canon 50D and Olympus E-P3 along with similar information for a selection of comparators.

One feature that is present on the 50D, but is missing on the E-P3 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The 50D writes its imaging data to Compact Flash cards, while the E-P3 uses SDXC cards.

 

Connectivity comparison

Studio photographers will appreciate that the Canon 50D (unlike the E-P3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 50D and the E-P3 have been discontinued, but can regularly be found used on eBay. The 50D was replaced by the Canon 60D, while the E-P3 was followed by the Olympus E-P5. 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? Is the Canon 50D better than the Olympus E-P3 or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Advantages of the Canon EOS 50D:

  • More detail: Offers more megapixels (15.1 vs 12.2MP) with a 13% higher linear resolution.
  • Better image quality: Scores substantially higher (12 points) in the DXO overall assessment.
  • More dynamic range: Captures a larger spectrum of light and dark details (1.3 EV of extra DR).
  • Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • More detailed LCD: Has a higher resolution rear screen (920k vs 614k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (6.3 vs 3 flaps/sec) to capture the decisive moment.
  • Longer lasting: Can take more shots (800 versus 330) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More heavily discounted: Has been available for much longer (launched in August 2008).

ilogo

Arguments in favor of the Olympus PEN E-P3:

  • Broader imaging potential: Can capture not only stills but also 1080/60i video.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More compact: Is smaller (122x69mm vs 146x108mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 453g or 55 percent) and is thus easier to take along.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • More affordable: Was introduced into a lower priced category (38 percent cheaper at launch).
  • More modern: Reflects 2 years and 10 months of technical progress since the 50D launch.

If the count of relative strengths (bullet points above) is taken as a measure, the 50D is the clear winner of the match-up (13 : 8 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.

50D 13:08 E-P3

How about other alternatives? Do the specifications of the Canon 50D and the Olympus E-P3 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings 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 50D or the E-P3. 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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
