Canon 7D vs Olympus E-P3
The Canon EOS 7D and the Olympus PEN E-P3 are two enthusiast cameras that were officially introduced, respectively, in September 2009 and June 2011. The 7D is a DSLR, while the E-P3 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (7D) and a Four Thirds (E-P3) sensor. The Canon has a resolution of 17.9 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 7D and the Olympus PEN E-P3? 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 7D and the Olympus E-P3 are illustrated 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 size dimensions are rounded to the nearest millimeter.
The E-P3 can be obtained in three different colors (black, silver, white), while the 7D 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-P3 is considerably smaller (49 percent) than the Canon 7D. Moreover, the E-P3 is substantially lighter (57 percent) than the 7D. It is worth mentioning in this context that the 7D is splash and dust resistant, 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 Canon EF Lens Catalog (7D) and the Micro Four Thirds Lens Catalog (E-P3). Mirrorless cameras, such as the E-P3, 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 table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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-P3 was launched at a markedly lower price (by 53 percent) than the 7D, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the imaging sensor is a crucial determinant 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 7D features an APS-C sensor and the Olympus E-P3 a Four Thirds sensor. The sensor area in the E-P3 is 32 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 7D has a native 3:2 aspect ratio, while the one in the E-P3 offers a 4:3 aspect.
With 17.9MP, the 7D offers a higher resolution than the E-P3 (12.2MP), but the 7D nevertheless has marginally larger individual pixels (pixel pitch of 4.31μm versus 4.29μm for the E-P3) due to its larger sensor. However, the E-P3 is a somewhat more recent model (by 1 year and 9 months) than the 7D, 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 7D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 7D for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Olympus E-P3 are 20.2 x 15.1 inches or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inches or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inches or 34.1 x 25.6 cm for excellent quality prints.
The Canon EOS 7D has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Olympus PEN E-P3 are ISO 200 to ISO 12800 (no boost).
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.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 7D provides substantially higher image quality than the E-P3, with an overall score that is 15 points higher. This advantage is based on 1.2 bits higher color depth, 1.6 EV in additional dynamic range, and 0.7 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the E-P3 provides a faster frame rate than the 7D. It can shoot movie footage at 1080/60i, while the Canon is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 7D 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. The table below summarizes some of the other core capabilities of the Canon 7D and Olympus E-P3 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 7D, but is missing on the E-P3 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 7D writes its imaging data to Compact Flash cards, while the E-P3 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 7D and Olympus PEN E-P3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 7D has a microphone port, which is missing on the E-P3. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Studio photographers will appreciate that the Canon 7D (unlike the E-P3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 7D and the E-P3 have been discontinued, but can regularly be found used on ebay. The 7D was replaced by the Canon 7D Mark II, while the E-P3 was followed by the Olympus E-P5. Further information on the features and operation of the 7D and E-P3 can be found, respectively, in the Canon 7D Manual (free pdf) or the online Olympus E-P3 Manual.
So how do things add up? Is the Canon 7D better than the Olympus E-P3 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Canon EOS 7D:
- More detail: Offers more megapixels (17.9 vs 12.2MP) with a 24% higher linear resolution.
- Better image quality: Scores substantially higher (15 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.2 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 (0.7 stops ISO advantage).
- Better sound: Can connect to an external microphone for higher quality sound recording.
- 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.
- More detailed LCD: Has a higher resolution rear screen (920k vs 614k dots).
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (8 vs 3 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (800 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 on the market for longer (launched in September 2009).
Advantages of the Olympus PEN E-P3:
- Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- More compact: Is smaller (122x69mm vs 148x111mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 491g or 57 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 (53 percent cheaper at launch).
- More modern: Was introduced somewhat (1 year and 9 months) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the 7D is the clear winner of the match-up (15 : 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 7D and the Olympus E-P3 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 remains incomplete and does no justice, for example, to the way the 7D or the E-P3 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 why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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 assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
