Canon 10D vs Olympus E-PM1
The Canon EOS 10D and the Olympus PEN E-PM1 are two digital cameras that were officially introduced, respectively, in February 2003 and June 2011. The 10D is a DSLR, while the E-PM1 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (10D) and a Four Thirds (E-PM1) sensor. The Canon has a resolution of 6.3 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 10D 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.
An illustration of the physical size and weight of the Canon 10D and the Olympus E-PM1 is provided 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.
The E-PM1 can be obtained in six different colors (black, silver, brown, pink, purple, white), while the 10D is only available in black.
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 (56 percent) than the Canon 10D. Moreover, the E-PM1 is substantially lighter (69 percent) than the 10D. In this context, it is worth noting that neither the 10D nor the E-PM1 are weather-sealed.
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 (10D) 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.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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 75 percent) than the 10D, 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.
The size of the sensor inside a digital camera is one of the key determinants 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon 10D features an APS-C sensor and the Olympus E-PM1 a Four Thirds sensor. The sensor area in the E-PM1 is 34 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 10D has a native 3:2 aspect ratio, while the one in the E-PM1 offers a 4:3 aspect.
Despite having a smaller sensor, the E-PM1 offers a higher resolution of 12.2 megapixels, compared with 6.3 MP of the 10D. 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 7.38μm for the 10D). However, it should be noted that the E-PM1 is much more recent (by 8 years and 4 months) than the 10D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Olympus E-PM1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-PM1 for good quality output (200 dots per inch) amounts to 20.2 x 15.1 inch or 51.2 x 38.4 cm, for very good quality (250 dpi) 16.1 x 12.1 inch or 41 x 30.7 cm, and for excellent quality (300 dpi) 13.4 x 10.1 inch or 34.1 x 25.6 cm. The corresponding values for the Canon 10D are 15.4 x 10.2 inch or 39 x 26 cm for good quality, 12.3 x 8.2 inch or 31.2 x 20.8 cm for very good quality, and 10.2 x 6.8 inch or 26 x 17.3 cm for excellent quality prints.
The Canon EOS 10D has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Olympus PEN E-PM1 are ISO 100 to ISO 12800 (no boost).
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 10D has a notably higher overall DXO score than the E-PM1 (overall score 5 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.1 bits higher color depth, 0.6 EV in additional dynamic range, and 0.2 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.

Many modern cameras cannot only take still pictures, but also record videos. The E-PM1 indeed provides for movie recording, while the 10D does not. The highest resolution format that the E-PM1 can use is 1080/60i.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the 10D 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 following table reports on some other key feature differences and similarities of the Canon 10D, the Olympus E-PM1, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The 10D has one, while the E-PM1 does not. While the built-in flash of the 10D is not very powerful, it can at times be useful as a fill-in light.
The 10D writes its imaging data to Compact Flash cards, while the E-PM1 uses SDXC cards.
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 10D and Olympus PEN E-PM1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 10D (unlike the E-PM1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 10D and the E-PM1 have been discontinued, but can regularly be found used on eBay. The 10D was replaced by the Canon 20D, 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.
So what is the bottom line? Is there a clear favorite between the Canon 10D and the Olympus E-PM1? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Canon EOS 10D:
- Better image quality: Scores markedly higher (5 points) in the DXO overall assessment.
- More dynamic range: Captures a larger spectrum of light and dark details (0.6 EV of extra DR).
- 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.
- Longer lasting: Can take more shots (500 versus 330) on a single battery charge.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- 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 February 2003).
Arguments in favor of the Olympus PEN E-PM1:
- More detail: Has more megapixels (12.2 vs 6.3MP), which boosts linear resolution by 37%.
- Broader imaging potential: Can capture not only stills but also 1080/60i video.
- Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (460k vs 118k dots).
- Faster burst: Shoots at higher frequency (5.5 vs 3 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (110x64mm vs 150x107mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 585g or 69 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.
- Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
- More affordable: Was introduced into a lower priced category (75 percent cheaper at launch).
- More modern: Reflects 8 years and 4 months of technical progress since the 10D launch.
If the count of individual advantages (bullet points above) is taken as a guide, the E-PM1 is the clear winner of the contest (12 : 8 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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.
How about other alternatives? Do the specifications of the Canon 10D 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 10D or the E-PM1 perform in practice. 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.
Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
