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 (E-5) sensor. The Canon has a resolution of 22.1 megapixel, whereas the Olympus provides 12.2 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 5D Mark III vs Olympus E-5

An illustration of the physical size and weight of the Canon 5D Mark III and the Olympus E-5 is provided 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 you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the 5D Mark III – represents the basis or 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 notably smaller (6 percent) than the Canon 5D Mark III. Moreover, the E-5 is markedly 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).

Concerning battery life, the 5D Mark III gets 950 shots out of its LP-E6 battery, while the E-5 can take 750 images on a single charge of its BLM-5 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Any camera purchase will naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. 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.

 

Sensor comparison: Canon 5D Mark III vs Olympus E-5

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 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.

Canon 5D Mark III and Olympus E-5 sensor measures

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.

5D Mark III versus E-5 MP

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 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.

 

Feature comparison: Canon 5D Mark III vs Olympus E-5

Apart from body and sensor, cameras can and do differ across a range 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 following table reports on some other key feature differences and similarities of the Canon 5D Mark III, the Olympus E-5, and comparable cameras.

One feature that differentiates the E-5 and the 5D Mark III is in-body image stabilization (IBIS). The E-5 reduces the risk of handshake-induced blur with all attached lenses, while the 5D Mark III has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The 5D Mark III writes its imaging data to Compact Flash cards, while the E-5 uses Compact Flash or xD Picture cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.

If the count of relative strengths (bullet points above) is taken as a measure, the 5D Mark III is the clear winner of the match-up (13 : 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 before making a camera decision.

5D Mark III 13:05 E-5

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. 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 adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
