Canon 1Ds vs Olympus E-PM1

The Canon EOS-1Ds and the Olympus PEN E-PM1 are two digital cameras that were officially introduced, respectively, in September 2002 and June 2011. The 1Ds is a DSLR, while the E-PM1 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (1Ds) and a Four Thirds (E-PM1) sensor. The Canon has a resolution of 11 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-1Ds and the Olympus PEN E-PM1? 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 physical size and weight of the Canon 1Ds and the Olympus E-PM1 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

The E-PM1 can be obtained in six different colors (black, silver, brown, pink, purple, white), while the 1Ds is only available in black.

Compare 1Ds versus E-PM1 top
Comparison 1Ds or E-PM1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-PM1 is considerably smaller (71 percent) than the Canon 1Ds. Moreover, the E-PM1 is substantially lighter (79 percent) than the 1Ds. It is worth mentioning in this context that the 1Ds is splash and dust resistant, while the E-PM1 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 Micro Four Thirds Lens Catalog (E-PM1). Mirrorless cameras, such as the E-PM1, 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 1Ds gets 600 shots out of its NP-E3 battery, while the E-PM1 can take 330 images on a single charge of its BLS-5 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-PM1 was launched at a markedly lower price (by 94 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. 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 features a full frame sensor and the Olympus E-PM1 a Four Thirds sensor. The sensor area in the E-PM1 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-PM1 offers a 4:3 aspect.

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

Canon 1Ds and Olympus E-PM1 sensor measures

Despite having a smaller sensor, the E-PM1 offers a higher resolution of 12.2 megapixels, compared with 11 MP of the 1Ds. 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 4.29μm versus 8.83μm for the 1Ds). However, it should be noted that the E-PM1 is much more recent (by 8 years and 9 months) than the 1Ds, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

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 PEN E-PM1 are ISO 100 to ISO 12800 (no boost).

1Ds versus E-PM1 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 1Ds provides substantially higher image quality than the E-PM1, with an overall score that is 11 points higher. This advantage is based on 0.8 bits higher color depth, 0.7 EV in additional dynamic range, and 0.9 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 also of capturing video footage. The E-PM1 indeed provides for movie recording, while the 1Ds does not. The highest resolution format that the E-PM1 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 1Ds has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-PM1 relies on live view and the rear LCD for framing. That said, the E-PM1 can be equipped with an optional viewfinder – the VF-2. The adjacent table lists some of the other core features of the Canon 1Ds and Olympus E-PM1 along with similar information for a selection of comparators.

One feature that is present on the 1Ds, but is missing on the E-PM1 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-PM1 uses SDXC cards.

 

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 (unlike the E-PM1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 1Ds and the E-PM1 have been discontinued, but can regularly be found used on eBay. The 1Ds was replaced by the Canon 1Ds Mark II, while the E-PM1 was followed by the Olympus E-PM2. 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? Which of the two cameras – the Canon 1Ds or the Olympus E-PM1 – 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:

  • Better image quality: Scores substantially higher (11 points) in the DXO overall assessment.
  • More dynamic range: Captures a larger spectrum of light and dark details (0.7 EV of extra DR).
  • Better low-light sensitivity: Requires less light for good images (0.9 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.
  • 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.
  • Longer lasting: Can take more shots (600 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 September 2002).

ilogo

Advantages of the Olympus PEN E-PM1:

  • Broader imaging potential: Can capture not only stills but also 1080/60i video.
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (460k vs 120k dots).
  • Faster burst: Shoots at higher frequency (5.5 vs 3 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (110x64mm vs 156x158mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 1000g or 79 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 (94 percent cheaper at launch).
  • More modern: Reflects 8 years and 9 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-PM1 (11 : 10 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.

1Ds 11:10 E-PM1

How about other alternatives? Do the specifications of the Canon 1Ds and the Olympus E-PM1 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the 1Ds and the E-PM1 in practical situations. 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.

Expert reviews

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
