Canon 1D Mark III vs Olympus E-M1 II

The Canon EOS-1D Mark III and the Olympus OM-D E-M1 Mark II are two digital cameras that were officially introduced, respectively, in February 2007 and September 2016. The 1D Mark III is a DSLR, while the E-M1 II is a mirrorless interchangeable lens camera. The cameras are based on an APS-H (1D Mark III) and a Four Thirds (E-M1 II) sensor. The Canon has a resolution of 10.1 megapixels, whereas the Olympus provides 20.2 MP. Read on to find out how these two cameras compare with respect to their body size, their sensors, their features, their input-output connections, and their reception by expert reviewers.

Body comparison: Canon 1D Mark III vs Olympus E-M1 II

An illustration of the physical size and weight of the Canon 1D Mark III and the Olympus E-M1 II is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures 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-M1 II is considerably smaller (50 percent) than the Canon 1D Mark III. Moreover, the E-M1 II is substantially lighter (50 percent) than the 1D 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 compare the optics available for the two cameras in the Canon EF Lens Catalog (1D Mark III) and the Micro Four Thirds Lens Catalog (E-M1 II). Mirrorless cameras, such as the E-M1 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-M1 II can take 440 images on a single charge of its BLH-1 power pack. As can be seen in the images above, the 1D Mark III has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the E-M1 II, Olympus provides the HLD-9 vertical grip as an optional accessory (see here on eBay).

The price is, of course, an important factor in any camera decision. 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-M1 II was launched at a markedly lower price (by 56 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-M1 II

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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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-M1 II a Four Thirds sensor. The sensor area in the E-M1 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-M1 II offers a 4:3 aspect.

Canon 1D Mark III and Olympus E-M1 II sensor measures

Despite having a smaller sensor, the E-M1 II offers a higher resolution of 20.2 megapixels, compared with 10.1 MP of the 1D Mark III. 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 3.34μm versus 7.21μm for the 1D Mark III). However, it should be noted that the E-M1 II is much more recent (by 9 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-M1 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The E-M1 II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.

Unlike the 1D Mark III, the E-M1 II has the capacity to capture high quality composite images (50MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Canon EOS-1D Mark III has a native sensitivity range from ISO 100 to ISO 3200, which can be extended to ISO 50-6400. The corresponding ISO settings for the Olympus OM-D E-M1 Mark II are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 64-25600..

1D Mark III versus E-M1 II MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the E-M1 II has a markedly higher DXO score than the 1D Mark III (overall score 9 points higher), which will translate into better image quality. The advantage is based on 1 bits higher color depth, 1.1 EV in additional dynamic range, and 0.3 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 cannot only take still pictures, but also record videos. The E-M1 II indeed provides for movie recording, while the 1D Mark III does not. The highest resolution format that the E-M1 II can use is 4K/30p.

 

Feature comparison: Canon 1D Mark III vs Olympus E-M1 II

Beyond body and sensor, cameras can and do differ across a range of features. For example, the E-M1 II has an electronic viewfinder (2360k dots), while the 1D Mark III has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the E-M1 II has a higher magnification than the one of the 1D Mark III (0.74x vs 0.58x), so that the size of the image transmitted appears closer to the size seen with the naked human eye.

One feature that is present on the 1D Mark III, but is missing on the E-M1 II is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The E-M1 II 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 1D Mark III does not have a selfie-screen.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the E-M1 II is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Olympus E-M1 II 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 1D Mark III writes its imaging data to Compact Flash or SDHC cards, while the E-M1 II uses SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. The E-M1 II supports UHS-II cards on its first slot and UHS-I on its second one, while the 1D Mark III cannot take advantage of Ultra High Speed SD cards.

 

Connectivity comparison: Canon 1D Mark III vs Olympus E-M1 II

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.

It is notable that the E-M1 II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 1D Mark III does not offer wifi capability.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

The E-M1 II is a recent model that features in the current product line-up of Olympus. In contrast, the 1D Mark III has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 1D Mark III was succeeded by the Canon 1D Mark IV. Further information on the two cameras, as well as related accessories, can be found on the official Canon and Olympus websites.

Notes: ++) highly recommended; +) recommended; o) reviewed; -) not available.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
