Canon 1D X Mark III vs Olympus E-M1
The Canon EOS-1D X Mark III and the Olympus OM-D E-M1 are two digital cameras that were revealed to the public, respectively, in January 2020 and September 2013. The 1DX Mark III is a DSLR, while the E-M1 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (1DX Mark III) and a Four Thirds (E-M1) sensor. The Canon has a resolution of 20 megapixels, whereas the Olympus provides 15.9 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-M1? 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.
The side-by-side display below illustrates the physical size and weight of the Canon 1D X Mark III and the Olympus E-M1. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.
The E-M1 can be obtained in two different colors (black, silver), while the 1DX Mark III is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M1 is considerably smaller (54 percent) than the Canon 1D X Mark III. Moreover, the E-M1 is substantially lighter (65 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-M1). Mirrorless cameras, such as the E-M1, 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-M1 can take 350 images on a single charge of its BLN-1 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. In order to provide similar functionality for the E-M1, Olympus provides the HLD-7 vertical grip as an optional accessory (see here on ebay).

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-M1 was launched at a markedly lower price (by 78 percent) than the 1DX Mark III, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 sensor inside a digital camera is one of the key determinants 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 1D X Mark III features a full frame sensor and the Olympus E-M1 a Four Thirds sensor. The sensor area in the E-M1 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-M1 offers a 4:3 aspect.
With 20MP, the 1DX Mark III offers a higher resolution than the E-M1 (15.9MP), but the 1DX Mark III nevertheless has larger individual pixels (pixel pitch of 6.57μm versus 3.76μm for the E-M1) due to its larger sensor. Moreover, the 1DX Mark III is a much more recent model (by 6 years and 3 months) than the E-M1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the E-M1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon 1D X Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 1DX Mark III for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Olympus E-M1 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.
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-M1 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under review, the 1DX Mark III provides substantially higher image quality than the E-M1, with an overall score that is 18 points higher. This advantage is based on 1.2 bits higher color depth, 1.8 EV in additional dynamic range, and 2.1 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 1DX Mark III provides a higher video resolution than the E-M1. It can shoot video footage at 4K/60p, while the Olympus is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the E-M1 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-M1 (0.76x vs 0.74x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 1D X Mark III and Olympus E-M1 in connection with corresponding information for a sample of similar cameras.

|Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.|
One feature that is present on the 1DX Mark III, but is missing on the E-M1 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 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 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-M1 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 (type B) cards, while the E-M1 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-M1 only has one slot.
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. The table below provides an overview of the connectivity of the Canon EOS-1D X Mark III and Olympus OM-D E-M1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 1DX Mark III has a headphone jack, which is not present on the E-M1 This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.
Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.
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.
The 1DX Mark III is a recent model that features in the current product line-up of Canon. In contrast, the E-M1 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-M1 was succeeded by the Olympus E-M1 II. Further information on the features and operation of the 1DX Mark III and E-M1 can be found, respectively, in the Canon 1D X Mark III Manual (free pdf) or the online Olympus E-M1 Manual.

If the count of individual advantages (bullet points above) is taken as a guide, the 1DX Mark III is the clear winner of the match-up (21 : 10 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Canon 1D X Mark III and the Olympus E-M1 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 1DX Mark III or the E-M1. 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.
This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], 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.

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.
