Canon 40D vs Olympus E-PL6
The Canon EOS 40D and the Olympus PEN E-PL6 are two digital cameras that were announced, respectively, in August 2007 and May 2013. The 40D is a DSLR, while the E-PL6 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (40D) and a Four Thirds (E-PL6) sensor. The Canon has a resolution of 10.1 megapixels, whereas the Olympus provides 15.9 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 40D and the Olympus PEN E-PL6? 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 40D and the Olympus E-PL6 is provided 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 size dimensions are rounded to the nearest millimeter.
The E-PL6 can be obtained in four different colors (black, silver, red, white), while the 40D 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-PL6 is considerably smaller (55 percent) than the Canon 40D. Moreover, the E-PL6 is substantially lighter (60 percent) than the 40D. In this context, it is worth noting that neither the 40D nor the E-PL6 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 (40D) and the Micro Four Thirds Lens Catalog (E-PL6). Mirrorless cameras, such as the E-PL6, 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. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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-PL6 was launched at a markedly lower price (by 54 percent) than the 40D, 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 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 40D features an APS-C sensor and the Olympus E-PL6 a Four Thirds sensor. The sensor area in the E-PL6 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 40D has a native 3:2 aspect ratio, while the one in the E-PL6 offers a 4:3 aspect.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
Despite having a smaller sensor, the E-PL6 offers a higher resolution of 15.9 megapixels, compared with 10.1 MP of the 40D. 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 3.76μm versus 5.73μm for the 40D). However, it should be noted that the E-PL6 is much more recent (by 5 years and 8 months) than the 40D, 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-PL6 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-PL6 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 cm. The corresponding values for the Canon 40D 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 Canon EOS 40D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Olympus PEN E-PL6 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
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"). 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 cannot only take still pictures, but also record videos. The E-PL6 indeed provides for movie recording, while the 40D does not. The highest resolution format that the E-PL6 can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the 40D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-PL6 relies on live view and the rear LCD for framing. That said, the E-PL6 can be equipped with an optional viewfinder – the VF-3. The adjacent table lists some of the other core features of the Canon 40D and Olympus E-PL6 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The 40D has one, while the E-PL6 does not. While the built-in flash of the 40D is not very powerful, it can at times be useful as a fill-in light.The E-PL6 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 40D does not have a selfie-screen.
The Olympus E-PL6 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The 40D writes its imaging data to Compact Flash cards, while the E-PL6 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 40D and Olympus PEN E-PL6 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 40D (unlike the E-PL6) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 40D and the E-PL6 have been discontinued, but can regularly be found used on eBay. The 40D was replaced by the Canon 50D, while the E-PL6 was followed by the Olympus E-PL7. 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 conclusions can be drawn? Is there a clear favorite between the Canon 40D and the Olympus E-PL6? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Canon EOS 40D:
- 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.
- Longer lasting: Can take more shots (750 versus 360) 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 August 2007).
Arguments in favor of the Olympus PEN E-PL6:
- More detail: Has more megapixels (15.9 vs 10.1MP), which boosts linear resolution by 23%.
- Broader imaging potential: Can capture not only stills but also 1080/30p video.
- More detailed LCD: Has a higher resolution rear screen (460k vs 230k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (8 vs 6.5 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More compact: Is smaller (111x64mm vs 146x108mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 497g or 60 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 (54 percent cheaper at launch).
- More modern: Reflects 5 years and 8 months of technical progress since the 40D launch.
If the count of relative strengths (bullet points above) is taken as a measure, the E-PL6 is the clear winner of the contest (14 : 7 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 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 40D or the E-PL6. 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.
This is why hands-on reviews by experts 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], 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
