Olympus E-P3 vs Canon 1D Mark III
The Olympus PEN E-P3 and the Canon EOS-1D Mark III are two digital cameras that were announced, respectively, in June 2011 and February 2007. The E-P3 is a mirrorless interchangeable lens camera, while the 1D Mark III is a DSLR. The cameras are based on a Four Thirds (E-P3) and an APS-H (1D Mark III) sensor. The Olympus has a resolution of 12.2 megapixels, whereas the Canon provides 10.1 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 Olympus PEN E-P3 and the Canon EOS-1D Mark III? 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 side-by-side display below illustrates the physical size and weight of the Olympus E-P3 and the Canon 1D Mark III. 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 dimensions are rounded to the nearest millimeter.
The E-P3 can be obtained in three different colors (black, silver, white), while the 1D Mark III 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 Canon 1D Mark III is considerably larger (191 percent) than the Olympus E-P3. Moreover, the 1D Mark III is substantially heavier (213 percent) than the E-P3. It is noteworthy in this context that the 1D Mark III is splash and dust-proof, while the E-P3 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 Micro Four Thirds Lens Catalog (E-P3) and the Canon EF Lens Catalog (1D Mark III). Mirrorless cameras, such as the Olympus E-P3, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.
Concerning battery life, the E-P3 gets 330 shots out of its Olympus BLS-5 battery, while the 1D Mark III can take 2200 images on a single charge of its Canon LP-E4 power pack. As can be seen in the images above, the 1D Mark III 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.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-P3 was launched at a markedly lower price (by 82 percent) than the 1D Mark III, 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
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Olympus E-P3 features a Four Thirds sensor and the Canon 1D Mark III an APS-H sensor. The sensor area in the 1D Mark III is 133 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.3. The sensor in the E-P3 has a native 4:3 aspect ratio, while the one in the 1D Mark III offers a 3:2 aspect.
Despite having a smaller sensor, the Olympus E-P3 offers a higher resolution of 12.2 megapixels, compared with 10.1 MP of the Canon 1D Mark III. 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 7.21μm for the 1D Mark III). However, it should be noted that the E-P3 is much more recent (by 4 years and 4 months) than the 1D Mark III, 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-P3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-P3 for good quality output (200 dots per inch) amounts to 20.2 x 15.1 inches or 51.2 x 38.4 cm, for very good quality (250 dpi) 16.1 x 12.1 inches or 41 x 30.7 cm, and for excellent quality (300 dpi) 13.4 x 10.1 inches or 34.1 x 25.6 cm. The corresponding values for the Canon 1D Mark III are 19.4 x 13 inches or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inches or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inches or 32.9 x 21.9 cm for excellent quality prints.
The Olympus PEN E-P3 has a native sensitivity range from ISO 200 to ISO 12800. The corresponding ISO settings for the Canon EOS-1D Mark III are ISO 100 to ISO 3200, with the possibility to increase the ISO range to 50-6400.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
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 consideration, the 1D Mark III offers substantially better image quality than the E-P3 (overall score 20 points higher). The advantage is based on 1.9 bits higher color depth, 1.6 EV in additional dynamic range, and 1 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 can also record movies. The E-P3 indeed provides movie recording capabilities, while the 1D Mark III does not. The highest resolution format that the E-P3 can use is 1080/60i.
Feature comparison
Apart from body and sensor, cameras can and do differ across a range of features. For example, the 1D Mark III has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-P3 relies on live view and the rear LCD for framing. That said, the E-P3 can be equipped with an optional viewfinder – the VF-3.

One difference between the cameras concerns the presence of an on-board flash. The E-P3 has one, while the 1D Mark III does not. While the built-in flash of the E-P3 is not very powerful, it can at times be useful as a fill-in light.
The E-P3 writes its imaging data to SDXC cards, while the 1D Mark III uses Compact Flash or SDHC cards. The 1D Mark III features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-P3 only has one slot. The E-P3 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 1D Mark III cannot take advantage of Ultra High Speed SD 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. The table below provides an overview of the connectivity of the Olympus PEN E-P3 and Canon EOS-1D Mark III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 1D Mark III (unlike the E-P3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the E-P3 and the 1D Mark III have been discontinued, but can regularly be found used on ebay. The 1D Mark III was replaced by the Canon 1D Mark IV, while the E-P3 was followed by the Olympus E-P5. Further information on the features and operation of the E-P3 and 1D Mark III can be found, respectively, in the Olympus E-P3 Manual (free pdf) or the online Canon 1D Mark III Manual.
Review summary
So how do things add up? Which of the two cameras – the Olympus E-P3 or the Canon 1D Mark III – 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.
Advantages of the Olympus PEN E-P3:
- More detail: Offers more megapixels (12.2 vs 10.1MP) with a 8% higher linear resolution.
- Broader imaging potential: Can record not only still images but also 1080/60i movies.
- More detailed LCD: Has a higher resolution rear screen (614k vs 230k dots).
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- More compact: Is smaller (122x69mm vs 156x157mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 786g or 68 percent) and hence easier to carry around.
- Sharper images: Has hand-shake reducing image stabilization built-in.
- More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More affordable: Was introduced into a lower priced category (82 percent cheaper at launch).
- More modern: Reflects 4 years and 4 months of technical progress since the 1D Mark III launch.
Arguments in favor of the Canon EOS-1D Mark III:
- Better image quality: Scores substantially higher (20 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.9 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (1.6 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (1 stops ISO advantage).
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Easier setting verification: Features a control panel on top to check shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (10 vs 3 flaps/sec) to capture the decisive moment.
- More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
- Longer lasting: Gets more shots (2200 versus 330) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More heavily discounted: Has been around for much longer (launched in February 2007).
If the count of relative strengths (bullet points above) is taken as a measure, the 1D Mark III emerges as the winner of the match-up (14 : 12 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Olympus E-P3 and the Canon 1D Mark III place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR 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 E-P3 or the 1D Mark III perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
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 (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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. 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.
