Canon G1 X Mark III vs Fujifilm GFX 50S
The Canon PowerShot G1 X Mark III and the Fujifilm GFX 50S are two digital cameras that were announced, respectively, in October 2017 and September 2016. The G1X Mark III is a fixed lens compact, while the GFX 50S is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (G1X Mark III) and a medium format (GFX 50S) sensor. The Canon has a resolution of 24 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 PowerShot G1 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.
An illustration of the physical size and weight of the Canon G1 X Mark III and the Fujifilm GFX 50S 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 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 larger (55 percent) than the Canon G1 X 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 and possibly misleading, as the G1X Mark III has a lens built in, whereas the GFX 50S is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The G1X Mark III was launched at a lower price than the GFX 50S, despite having a lens built in. 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.
The size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon G1 X Mark III features an APS-C sensor and the Fujifilm GFX 50S a medium format sensor. The sensor area in the GFX 50S is 337 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 0.79. The sensor in the G1X 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 G1X Mark III (24MP), but the GFX 50S nevertheless has larger individual pixels (pixel pitch of 5.33μm versus 3.72μm for the G1X Mark III) due to its larger sensor. However, the G1X Mark III is a somewhat more recent model (by 1 year) than the GFX 50S, and its sensor might have benefitted from technological advances during this time that 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 G1 X Mark III are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.
The G1X Mark III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon PowerShot G1 X Mark III has a native sensitivity range from ISO 100 to ISO 25600. 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 is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G1X Mark III provides a higher frame rate than the GFX 50S. It can shoot video footage at 1080/60p, while the Fujifilm is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the G1X Mark III has an electronic viewfinder (2360k dots), which can be very helpful 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 G1 X Mark III and Fujifilm GFX 50S along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The G1X Mark III has one, while the GFX 50S does not. While the built-in flash of the G1X Mark III is not very powerful, it can at times be useful as a fill-in light.The G1X Mark III has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the GFX 50S 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 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 G1 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.
Concerning the storage of imaging data, both the G1X Mark III and the GFX 50S write their files to SDXC cards. The GFX 50S features dual card slots, which can be very useful in case a memory card fails. In contrast, the G1X Mark III only has one slot. The GFX 50S supports UHS-II cards (on both slots), while the G1X Mark III can use UHS-I cards.
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 PowerShot G1 X Mark III and Fujifilm GFX 50S and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GFX 50S has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The G1X Mark III does not feature such a mic input.
Studio photographers will appreciate that the Fujifilm GFX 50S (unlike the G1X Mark III) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the G1X Mark III and the GFX 50S are recent models that are part of the current product line-up. The G1X Mark III replaced the earlier Canon G1 X Mark II, while the GFX 50S does not have a direct predecessor. 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.

If the count of individual advantages (bullet points above) is taken as a guide, the GFX 50S is the clear winner of the contest (20 : 15 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 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 G1 X Mark III and the Fujifilm GFX 50S place the cameras among the top in their class? Find out in the latest Best Travel-Zoom 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 says little about, for example, the shooting experience and imaging performance of the G1X Mark III and the GFX 50S in practical situations. 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 expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
