Body comparison: Canon 1D vs Olympus E-520

The side-by-side display below illustrates the physical size and weight of the Canon 1D and the Olympus E-520. 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 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-520 is considerably smaller (49 percent) than the Canon 1D. Moreover, the E-520 is substantially lighter (66 percent) than the 1D. It is worth mentioning in this context that the 1D is splash and dust resistant, while the E-520 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 (1D) and the Four Thirds Lens Catalog (E-520).

Concerning battery life, the 1D gets 500 shots out of its NP-E3 battery, while the E-520 can take 750 images on a single charge of its BLM-1 power pack. As can be seen in the images above, the 1D has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.

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-520 was launched at a markedly lower price (by 89 percent) than the 1D, 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: Canon 1D vs Olympus E-520

The size of the imaging sensor is a crucial determinant 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. 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 1D features an APS-H sensor and the Olympus E-520 a Four Thirds sensor. The sensor area in the E-520 is 59 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 2.0. The sensor in the 1D has a native 3:2 aspect ratio, while the one in the E-520 offers a 4:3 aspect.

Canon 1D and Olympus E-520 sensor measures

Despite having a smaller sensor, the E-520 offers a higher resolution of 10 megapixels, compared with 4.1 MP of the 1D. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.74μm versus 11.56μm for the 1D). However, it should be noted that the E-520 is much more recent (by 6 years and 7 months) than the 1D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The Canon EOS-1D has a native sensitivity range from ISO 200 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Olympus E-520 are ISO 100 to ISO 1600 (no boost).

1D versus E-520 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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").

The E-520 offers Live View, so that it can project the live image that the sensor receives onto the rear screen for framing. The 1D lacks this capability. Both cameras are still-image focused and cannot record videos.
 

Feature comparison: Canon 1D vs Olympus E-520

Apart from body and sensor, cameras can and do differ across a range of features. The 1D and the E-520 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 1D offers a wider field of view (100%) than the one in the E-520 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 1D has a higher magnification (0.55x vs 0.46x), 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 1D, the Olympus E-520, and comparable cameras.

One feature that is present on the 1D, but is missing on the E-520 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 1D writes its imaging data to Compact Flash cards, while the E-520 uses Compact Flash or xD Picture cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.

 

Connectivity comparison: Canon 1D vs Olympus E-520

Studio photographers will appreciate that the Canon 1D (unlike the E-520) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 1D and the E-520 have been discontinued, but can regularly be found used on eBay. The 1D was replaced by the Canon 1D Mark II, while the E-520 does not have a direct successor.


Review summary: Canon 1D vs Olympus E-520

So what conclusions can be drawn? Which of the two cameras – the Canon 1D or the Olympus E-520 – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Reasons to prefer the Canon EOS-1D:

  • More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.55x vs 0.46x).
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (16000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (8 vs 3.5 flaps/sec) to capture the decisive moment.
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • 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.

ilogo

Arguments in favor of the Olympus E-520:

  • More detail: Has more megapixels (10 vs 4.1MP), which boosts linear resolution by 52%.
  • Larger screen: Has a bigger rear LCD (2.7" vs 2.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (215k vs 120k dots).
  • More compact: Is smaller (136x92mm vs 156x158mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 1050g or 66 percent) and is thus easier to take along.
  • Longer lasting: Gets more shots (750 versus 500) out of a single battery charge.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (89 percent cheaper at launch).
  • More modern: Reflects 6 years and 7 months of technical progress since the 1D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the E-520 comes out slightly ahead of the 1D (10 : 9 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.

1D 09:10 E-520

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 1D or the E-520. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

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

Care should be taken when interpreting the review scores above, 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
