Canon 1Ds Mark III vs Olympus E-520

The Canon EOS-1Ds Mark III and the Olympus E-520 are two digital cameras that were revealed to the public, respectively, in August 2007 and May 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (1Ds Mark III) and a Four Thirds (E-520) sensor. The Canon has a resolution of 21 megapixels, whereas the Olympus provides 10 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-1Ds Mark III and the Olympus E-520? 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 1Ds Mark III and the Olympus E-520 is provided in the side-by-side display below. 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 measures are rounded to the nearest millimeter.

Compare 1Ds Mark III versus E-520 top
Comparison 1Ds Mark III or E-520 rear

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 (48 percent) than the Canon 1Ds Mark III. Moreover, the E-520 is substantially lighter (61 percent) than the 1Ds Mark III. It is worth mentioning in this context that the 1Ds Mark III 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 (1Ds Mark III) and the Four Thirds Lens Catalog (E-520).

Concerning battery life, the 1Ds Mark III gets 1800 shots out of its LP-E4 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 1Ds Mark III has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.

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-520 was launched at a markedly lower price (by 91 percent) than the 1Ds Mark III, 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. 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 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. 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 1Ds Mark III features a full frame sensor and the Olympus E-520 a Four Thirds sensor. The sensor area in the E-520 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the 1Ds Mark III has a native 3:2 aspect ratio, while the one in the E-520 offers a 4:3 aspect.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Canon 1Ds Mark III and Olympus E-520 sensor measures

With 21MP, the 1Ds Mark III offers a higher resolution than the E-520 (10MP), but the 1Ds Mark III nevertheless has larger individual pixels (pixel pitch of 6.41μm versus 4.74μm for the E-520) due to its larger sensor. However, the E-520 is a somewhat more recent model (by 8 months) than the 1Ds Mark III, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

The resolution advantage of the Canon 1Ds Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 1Ds Mark III for good quality output (200 dots per inch) amounts to 28.1 x 18.7 inch or 71.3 x 47.5 cm, for very good quality (250 dpi) 22.5 x 15 inch or 57.1 x 38 cm, and for excellent quality (300 dpi) 18.7 x 12.5 inch or 47.5 x 31.7 cm. The corresponding values for the Olympus E-520 are 18.2 x 13.7 inch or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inch or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inch or 30.9 x 23.2 cm for excellent quality prints.

The Canon EOS-1Ds Mark III has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 50-3200. The corresponding ISO settings for the Olympus E-520 are ISO 100 to ISO 1600 (no boost).

1Ds Mark III versus E-520 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"). Of the two cameras under review, the 1Ds Mark III provides substantially higher image quality than the E-520, with an overall score that is 25 points higher. This advantage is based on 2.6 bits higher color depth, 1.6 EV in additional dynamic range, and 1.6 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Both the 1Ds Mark III and the E-520 offer Live View, so that they make it possible to use the rear screen for framing. Both cameras are still-image focused and cannot record videos.
 

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 1Ds Mark III 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 1Ds Mark III 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 1Ds Mark III has a higher magnification (0.76x 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 1Ds Mark III, the Olympus E-520, and comparable cameras.

One feature that is present on the 1Ds Mark III, 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 1Ds Mark III writes its imaging data to Compact Flash or SDHC cards, while the E-520 uses Compact Flash or xD Picture cards. The E-520 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 1Ds Mark III 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.

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

Both the 1Ds Mark III and the E-520 have been discontinued, but can regularly be found used on eBay. The 1Ds Mark III was replaced by the Canon 1DX, while the E-520 does not have a direct successor. 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 how do things add up? Which of the two cameras – the Canon 1Ds Mark III or the Olympus E-520 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Arguments in favor of the Canon EOS-1Ds Mark III:

  • More detail: Offers more megapixels (21 vs 10MP) with a 48% higher linear resolution.
  • Better image quality: Scores substantially higher (25 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (2.6 bits more color depth).
  • More dynamic range: Captures a larger spectrum of light and dark details (1.6 EV of extra DR).
  • Better low-light sensitivity: Requires less light for good images (1.6 stops ISO advantage).
  • 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 (0.76x vs 0.46x).
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (5 vs 3.5 flaps/sec) to capture the decisive moment.
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Longer lasting: Can take more shots (1800 versus 750) 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 on the market for longer (launched in August 2007).

ilogo

Reasons to prefer the Olympus E-520:

  • More compact: Is smaller (136x92mm vs 150x160mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 850g or 61 percent) and is thus easier to take along.
  • 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.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More affordable: Was introduced into a lower priced category (91 percent cheaper at launch).
  • More modern: Was introduced somewhat (8 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the 1Ds Mark III is the clear winner of the match-up (16 : 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 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.

1Ds Mark III 16:07 E-520

How about other alternatives? Do the specifications of the Canon 1Ds Mark III and the Olympus E-520 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 1Ds Mark III or the E-520. 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 adjacent summary-table relays the overall verdicts of several of the most popular 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.

Care should be taken when interpreting the review scores above, 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
