Canon 40D vs Olympus E-5
The Canon EOS 40D and the Olympus E-5 are two digital cameras that were announced, respectively, in August 2007 and September 2010. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (40D) and a Four Thirds (E-5) sensor. The Canon has a resolution of 10.1 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 40D and the Olympus E-5? 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 40D and the Olympus E-5 are illustrated 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 dimensions are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-5 is notably larger (5 percent) than the Canon 40D. Moreover, the E-5 is markedly heavier (6 percent) than the 40D. It is noteworthy in this context that the E-5 is splash and dust-proof, while the 40D 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 (40D) and the Four Thirds Lens Catalog (E-5).
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The 40D was launched at a somewhat lower price (by 24 percent) than the E-5, which makes it more attractive for photographers on a tight budget. 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 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 40D features an APS-C sensor and the Olympus E-5 a Four Thirds sensor. The sensor area in the E-5 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-5 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-5 offers a higher resolution of 12.2 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 4.29μm versus 5.73μm for the 40D). However, it should be noted that the E-5 is much more recent (by 3 years) 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-5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-5 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 40D are 19.4 x 13 inch or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inch or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inch 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 E-5 are ISO 100 to ISO 6400 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under review, the 40D has a notably higher overall DXO score than the E-5 (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.5 bits higher color depth, 0.8 EV in additional dynamic range, and 0.4 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-5 indeed provides for movie recording, while the 40D does not. The highest resolution format that the E-5 can use is 720/30p.
Beyond body and sensor, cameras can and do differ across a range of features. The 40D and the E-5 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinder in the E-5 offers a wider field of view (100%) than the one in the 40D (95%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the 40D has a higher magnification (0.59x vs 0.575x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon 40D and Olympus E-5 along with similar information for a selection of comparators.

One feature that differentiates the E-5 and the 40D is in-body image stabilization (IBIS). The E-5 reduces the risk of handshake-induced blur with all attached lenses, while the 40D has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.The E-5 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 40D writes its imaging data to Compact Flash cards, while the E-5 uses Compact Flash or xD Picture cards. The E-5 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 40D only has one slot.
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 E-5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.
Both the 40D and the E-5 have been discontinued, but can regularly be found used on eBay. The 40D was replaced by the Canon 50D, while the E-5 does not have a direct successor. 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? Which of the two cameras – the Canon 40D or the Olympus E-5 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Canon EOS 40D:
- Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
- More dynamic range: Captures a larger spectrum of light and dark details (0.8 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.59x vs 0.575x).
- Faster burst: Shoots at higher frequency (6.5 vs 5 flaps/sec) to capture the decisive moment.
- More affordable: Was introduced into a lower priced segment (24 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in August 2007).
Advantages of the Olympus E-5:
- More detail: Has more megapixels (12.2 vs 10.1MP), which boosts linear resolution by 8%.
- Broader imaging potential: Can capture not only stills but also 720/30p video.
- More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
- More detailed LCD: Has a higher resolution rear screen (920k vs 230k dots).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More modern: Reflects 3 years of technical progress since the 40D launch.
If the number of relative strengths (bullet points above) is taken as a guide, the E-5 emerges as the winner of the match-up (10 : 7 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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.
How about other alternatives? Do the specifications of the Canon 40D and the Olympus E-5 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing 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 40D or the E-5 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.
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.
