Canon 5D Mark III versus Olympus E-5
The Canon EOS 5D Mark III and the Olympus E-5 are two professional cameras that were officially introduced, respectively, in March 2012 and September 2010. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (5D Mark III) and a Four Thirds sensor. The Canon has a resolution of 22.1 megapixel, whereas the Olympus provides 12.2 MP.
The side-by-side display below illustrates the physical size and weight of the Canon 5D Mark III and the Olympus E-5. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the 5D Mark III – represents 100 percent across all the size and weight measures).
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 somewhat smaller (6 percent) than the Canon 5D Mark III. Moreover, the E-5 is slightly lighter (8 percent) than the 5D Mark III. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.
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 find an overview of optics for the two cameras in the Canon EF Lens Catalog (5D Mark III) and the Four Thirds Lens Catalog (E-5).
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, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-5 was launched at a markedly lower price (by 51 percent) than the 5D 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. 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. 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 tent to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 5D Mark III features a full frame sensor and the Olympus E-5 a Four Thirds sensor. The sensor area in the E-5 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the 5D Mark III has a native 3:2 aspect ratio, while the one in the E-5 offers a 4:3 aspect.
With 22.1MP, the 5D Mark III offers a higher resolution than the E-5 (12.2MP), but the 5D Mark III nevertheless has larger individual pixels (pixel pitch of 6.25μm versus 4.29μm for the E-5) due to its larger sensor. Moreover, the 5D Mark III is a somewhat more recent model (by 1 year and 5 months) than the E-5, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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 5D Mark III provides substantially higher image quality than the E-5, with an overall score that is 25 points higher. This advantage is based on 2.4 bits higher color depth, 1.2 EV in additional dynamic range, and 2.1 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 are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the 5D Mark III provides a higher video resolution than the E-5. It can shoot video footage at 1080/30p, while the Olympus is limited to 720/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The 5D Mark III 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 table below summarizes some of the other core capabilities of the Canon 5D Mark III and Olympus E-5 in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

If the count of individual advantages (bullet points above) is taken as a guide, the 5D Mark III is the clear winner of the match-up (10 : 5 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.
In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the 5D Mark III and the E-5 in practical situations. 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 table below summarizes the assessments of some of the best known camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The review scores listed above should be treated with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
