Canon 1Ds vs Olympus E-520
The Canon EOS-1Ds and the Olympus E-520 are two digital cameras that were officially introduced, respectively, in September 2002 and May 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (1Ds) and a Four Thirds (E-520) sensor. The Canon has a resolution of 11 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 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.
The physical size and weight of the Canon 1Ds and the Olympus E-520 are illustrated in the side-by-side display below. 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 measures 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 1Ds. Moreover, the E-520 is substantially lighter (58 percent) than the 1Ds. It is worth mentioning in this context that the 1Ds 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) and the Four Thirds Lens Catalog (E-520).
Concerning battery life, the 1Ds gets 600 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 1Ds has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

|Note: Measurements and pricing do not include easily detachable parts, such as 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-520 was launched at a markedly lower price (by 92 percent) than the 1Ds, 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.
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 1Ds 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 has a native 3:2 aspect ratio, while the one in the E-520 offers a 4:3 aspect.
With 11MP, the 1Ds offers a higher resolution than the E-520 (10MP), but the 1Ds nevertheless has larger individual pixels (pixel pitch of 8.83μm versus 4.74μm for the E-520) due to its larger sensor. However, the E-520 is a much more recent model (by 5 years and 7 months) than the 1Ds, 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 1Ds implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 1Ds for good quality output (200 dots per inch) amounts to 20.3 x 13.5 inch or 51.6 x 34.3 cm, for very good quality (250 dpi) 16.3 x 10.8 inch or 41.3 x 27.5 cm, and for excellent quality (300 dpi) 13.5 x 9 inch or 34.4 x 22.9 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 has a native sensitivity range from ISO 100 to ISO 1250, which can be extended to ISO 50-1250. The corresponding ISO settings for the Olympus E-520 are ISO 100 to ISO 1600 (no boost).
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"). Of the two cameras under review, the 1Ds has a notably higher overall DXO score than the E-520 (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.4 bits higher color depth, 0.6 EV in additional dynamic range, and 0.8 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.

Beyond body and sensor, cameras can and do differ across a range of features. The 1Ds 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 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 has a higher magnification (0.70x vs 0.46x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 1Ds and Olympus E-520 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 1Ds, 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 writes its imaging data to Compact Flash 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 only has one slot.
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-1Ds and Olympus E-520 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 1Ds (unlike the E-520) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 1Ds and the E-520 have been discontinued, but can regularly be found used on eBay. The 1Ds was replaced by the Canon 1Ds Mark II, 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.
So how do things add up? Is there a clear favorite between the Canon 1Ds and the Olympus E-520? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Canon EOS-1Ds:
- More detail: Offers more megapixels (11 vs 10MP) with a 7% higher linear resolution.
- Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
- More dynamic range: Captures a larger spectrum of light and dark details (0.6 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (0.8 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 (0.70x vs 0.46x).
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- 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.
- More heavily discounted: Has been available for much longer (launched in September 2002).
Reasons to prefer the Olympus E-520:
- 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).
- Faster burst: Shoots at higher frequency (3.5 vs 3 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (136x92mm vs 156x158mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 730g or 58 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (750 versus 600) 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.
- 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 (92 percent cheaper at launch).
- More modern: Reflects 5 years and 7 months of technical progress since the 1Ds launch.
If the count of relative strengths (bullet points above) is taken as a measure, the 1Ds comes out slightly ahead of the E-520 (12 : 11 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.
How about other alternatives? Do the specifications of the Canon 1Ds 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 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 1Ds and the E-520 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.
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 (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.

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.
