Canon 1D X Mark III vs Olympus E-M5 III

The Canon EOS-1D X Mark III and the Olympus OM-D E-M5 Mark III are two digital cameras that were revealed to the public, respectively, in January 2020 and October 2019. The 1DX Mark III is a DSLR, while the E-M5 III is a mirrorless interchangeable lens camera. The cameras are based on a full frame (1DX Mark III) and a Four Thirds (E-M5 III) sensor. The Canon has a resolution of 20 megapixels, whereas the Olympus provides 20.2 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-1D X Mark III and the Olympus OM-D E-M5 Mark III? 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.

Body comparison

The physical size and weight of the Canon 1D X Mark III and the Olympus E-M5 III are illustrated 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 size dimensions are rounded to the nearest millimeter.

The E-M5 III can be obtained in two different colors (black, silver), while the 1DX Mark III is only available in black.

Compare 1DX Mark III versus E-M5 III top
Comparison 1DX Mark III or E-M5 III rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M5 III is considerably smaller (60 percent) than the Canon 1D X Mark III. Moreover, the E-M5 III is substantially lighter (71 percent) than the 1DX 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 (1DX Mark III) and the Micro Four Thirds Lens Catalog (E-M5 III). Mirrorless cameras, such as the E-M5 III, 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 1DX Mark III gets 2850 shots out of its LP-E19 battery, while the E-M5 III can take 310 images on a single charge of its BLS-50 power pack. As can be seen in the images above, the 1DX Mark III has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. The power pack in the E-M5 III can be charged via the USB port, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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-M5 III was launched at a markedly lower price (by 82 percent) than the 1DX 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

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 generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 1D X Mark III features a full frame sensor and the Olympus E-M5 III a Four Thirds sensor. The sensor area in the E-M5 III 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 1DX Mark III has a native 3:2 aspect ratio, while the one in the E-M5 III offers a 4:3 aspect.

In terms of underlying technology, both cameras are build around CMOS sensors.

Canon 1D X Mark III and Olympus E-M5 III sensor measures

Despite having a smaller sensor, the E-M5 III offers a slightly higher resolution of 20.2 megapixels, compared with 20 MP of the 1DX 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 6.57μm for the 1DX Mark III). It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. Coming back to sensor resolution, it should be mentioned that the E-M5 III has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Unlike the 1DX Mark III, the E-M5 III has the capacity to capture high quality composite images (80MP) 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 X Mark III has a native sensitivity range from ISO 100 to ISO 102400, which can be extended to ISO 50-819200. The corresponding ISO settings for the Olympus OM-D E-M5 Mark III are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 64-25600.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the 1DX Mark III provides a higher frame rate than the E-M5 III. It can shoot video footage at 4K/60p, while the Olympus is limited to 4K/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the E-M5 III has an electronic viewfinder (2360k dots), while the 1DX 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 1DX Mark III has a higher magnification than the one of the E-M5 III (0.76x vs 0.68x), 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 1D X Mark III and Olympus E-M5 III along with similar information for a selection of comparators.

One feature that is present on the 1DX Mark III, but is missing on the E-M5 III 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-M5 III 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 1DX 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-M5 III 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 Canon 1D X Mark III and the Olympus E-M5 III both have 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 1DX Mark III writes its imaging data to CFexpress cards, while the E-M5 III uses SDXC cards. The 1DX Mark III features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-M5 III only has one slot.

It is notable that the 1DX Mark III has a headphone jack, which is not present on the E-M5 III This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.

Studio photographers will appreciate that the Canon 1D X Mark III (unlike the E-M5 III) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Travel and landscape photographers will find it useful that the 1DX Mark III has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the 1DX Mark III and the E-M5 III are recent models that are part of the current product line-up. The E-M5 III replaced the earlier Olympus E-M5 II, while the 1DX Mark III followed on from the Canon 1DX Mark II. 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.

If the count of relative strengths (bullet points above) is taken as a measure, the 1DX Mark III is the clear winner of the match-up (19 : 12 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. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

1DX Mark III 19:12 E-M5 III

How about other alternatives? Do the specifications of the Canon 1D X Mark III and the Olympus E-M5 III place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings 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 says little about, for example, the shooting experience and imaging performance of the 1DX Mark III and the E-M5 III in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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.

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

The review scores listed above should be treated with care, though. The ratings are only valid when referring 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
