Canon 1D X Mark III vs Fujifilm GFX 50S
The Canon EOS-1D X Mark III and the Fujifilm GFX 50S are two professional cameras that were revealed to the public, respectively, in January 2020 and September 2016. The 1DX Mark III is a DSLR, while the GFX 50S is a mirrorless interchangeable lens camera. The cameras are based on a full frame (1DX Mark III) and a medium format (GFX 50S) sensor. The Canon has a resolution of 20 megapixels, whereas the Fujifilm provides 51.1 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 Fujifilm GFX 50S? 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 physical size and weight of the Canon 1D X Mark III and the Fujifilm GFX 50S 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 width, height and depth dimensions 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 Fujifilm GFX 50S is considerably smaller (48 percent) than the Canon 1D X Mark III. Moreover, the GFX 50S is substantially lighter (49 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
Concerning battery life, the 1DX Mark III gets 2850 shots out of its LP-E19 battery, while the GFX 50S can take 400 images on a single charge of its NP-T125 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 GFX 50S, Fujifilm provides the VG-GFX1 vertical grip as an optional accessory (see here on eBay).
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision 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 two cameras under review were launched at the same price and fall into the same 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.
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 1D X Mark III features a full frame sensor and the Fujifilm GFX 50S a medium format sensor. The sensor area in the GFX 50S is 68 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 0.79. The sensor in the 1DX Mark III has a native 3:2 aspect ratio, while the one in the GFX 50S offers a 4:3 aspect.
With 51.1MP, the GFX 50S offers a higher resolution than the 1DX Mark III (20MP), but the GFX 50S has smaller individual pixels (pixel pitch of 5.33μm versus 6.57μm for the 1DX Mark III). Yet, the 1DX Mark III is a much more recent model (by 3 years and 3 months) than the GFX 50S, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the GFX 50S has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Fujifilm GFX 50S implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GFX 50S for good quality output (200 dots per inch) amounts to 41.3 x 31 inches or 104.9 x 78.6 cm, for very good quality (250 dpi) 33 x 24.8 inches or 83.9 x 62.9 cm, and for excellent quality (300 dpi) 27.5 x 20.6 inches or 69.9 x 52.4 cm. The corresponding values for the Canon 1D X Mark III are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.
The 1DX Mark III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
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 Fujifilm GFX 50S are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 50-102400.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the 1DX Mark III provides a higher video resolution than the GFX 50S. It can shoot video footage at 4K/60p, while the Fujifilm is limited to 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the 1DX Mark III has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the GFX 50S relies on live view and the rear LCD for framing. That said, the GFX 50S can be equipped with an optional viewfinder – the EVF-TL1. The adjacent table lists some of the other core features of the Canon 1D X Mark III and Fujifilm GFX 50S along with similar information for a selection of comparators.

|Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.|
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 GFX 50S 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 Fujifilm GFX 50S 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 GFX 50S uses SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.
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 Fujifilm GFX 50S and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

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 GFX 50S has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the GFX 50S was succeeded by the Fujifilm GFX 50S 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 Fujifilm websites.
So what conclusions can be drawn? Is there a clear favorite between the Canon 1D X Mark III and the Fujifilm GFX 50S? Which camera is better? The listing below highlights the relative strengths of the two models.

If the count of relative strengths (bullet points above) is taken as a measure, the 1DX Mark III emerges as the winner of the contest (11 : 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. 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.
How about other alternatives? Do the specifications of the Canon 1D X Mark III and the Fujifilm GFX 50S 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 remains incomplete and does no justice, for example, to the way the 1DX Mark III or the GFX 50S perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, please note that some of the review sites have changed their methodology and reporting over time.
