Canon 1D Mark III versus Olympus E-M10 II

The Canon EOS-1D Mark III and the Olympus OM-D E-M10 Mark II are two digital cameras that were officially introduced, respectively, in February 2007 and August 2015. The 1D Mark III is a DSLR, while the E-M10 II is a mirrorless interchangeable lens camera. The cameras are based on an APS-H (1D Mark III) and a Four Thirds (E-M10 II) sensor. The Canon has a resolution of 10.1 megapixel, whereas the Olympus provides 15.9 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 1D Mark III vs Olympus E-M10 II

The physical size and weight of the Canon 1D Mark III and the Olympus E-M10 II are illustrated in the side-by-side display below. 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. 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 side – the 1D Mark III – represents the basis for the calculations 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-M10 II is considerably smaller (59 percent) than the Canon 1D Mark III. Moreover, the E-M10 II is substantially lighter (66 percent) than the 1D Mark III. It is worth mentioning in this context that the 1D Mark III is splash and dust resistant, while the E-M10 II 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 find an overview of optics for the two cameras in the Canon EF Lens Catalog (1D Mark III) and the Micro Four Thirds Lens Catalog (E-M10 II). Mirrorless cameras, such as the E-M10 II, 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.

Concerning battery life, the 1D Mark III gets 2200 shots out of its LP-E4 battery, while the E-M10 II can take 320 images on a single charge of its BLS-50 power pack.

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 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-M10 II was launched at a markedly lower price (by 82 percent) than the 1D 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.

 

Sensor comparison: Canon 1D Mark III vs Olympus E-M10 II

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 tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 1D Mark III features an APS-H sensor and the Olympus E-M10 II a Four Thirds sensor. The sensor area in the E-M10 II is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 2.0. The sensor in the 1D Mark III has a native 3:2 aspect ratio, while the one in the E-M10 II offers a 4:3 aspect.

Canon 1D Mark III and Olympus E-M10 II sensor measures

Despite having a smaller sensor, the E-M10 II offers a higher resolution of 15.9 megapixel, compared with 10.1 MP of the 1D Mark III. This megapixel 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 7.21μm for the 1D Mark III). However, it should be noted that the E-M10 II is much more recent (by 8 years and 6 months) than the 1D Mark III, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the E-M10 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

If the number of relative strengths (bullet points above) is taken as a guide, the E-M10 II is the clear winner of the contest (15 : 9 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.

1D Mark III 09:15 E-M10 II

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 1D Mark III or the E-M10 II. 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).

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. 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.
