Fujifilm GFX 50S vs Panasonic GX800
The Fujifilm GFX 50S and the Panasonic Lumix DMC-GX800 (labelled Panasonic GX850 in some countries) are two digital cameras that were revealed to the public, respectively, in September 2016 and January 2017. Both the GFX 50S and the GX800 are mirrorless interchangeable lens cameras that are based on a medium format (GFX 50S) and a Four Thirds (GX800) sensor. The Fujifilm has a resolution of 51.1 megapixels, whereas the Panasonic provides 15.8 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 Fujifilm GFX 50S and the Panasonic Lumix DMC-GX800? 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 Fujifilm GFX 50S and the Panasonic GX800 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.
The GX800 can be obtained in three different colors (black, silver, red), while the GFX 50S 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 Panasonic GX800 is considerably smaller (50 percent) than the Fujifilm GFX 50S. Moreover, the GX800 is substantially lighter (64 percent) than the GFX 50S. It is worth mentioning in this context that the GFX 50S is splash and dust resistant, while the GX800 does not feature any corresponding weather-sealing.
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.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The GX800 was launched at a markedly lower price (by 92 percent) than the GFX 50S, 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.
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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Fujifilm GFX 50S features a medium format sensor and the Panasonic GX800 a Four Thirds sensor. The sensor area in the GX800 is 85 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 0.79 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
With 51.1MP, the GFX 50S offers a higher resolution than the GX800 (15.8MP), but the GFX 50S nevertheless has larger individual pixels (pixel pitch of 5.33μm versus 3.77μm for the GX800) due to its larger sensor. However, the GX800 is a somewhat more recent model (by 3 months) than the GFX 50S, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the 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 Panasonic GX800 are 23 x 17.2 inches or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inches or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inches or 38.9 x 29.2 cm for excellent quality prints.
The Fujifilm GFX 50S has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 50-102400. The corresponding ISO settings for the Panasonic Lumix DMC-GX800 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 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 GX800 provides a better video resolution than the GFX 50S. It can shoot movie footage at 4K/30p, while the Fujifilm is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The GFX 50S and the GX800 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. That said, the GFX 50S can be equipped with an optional viewfinder – the EVF-TL1. The following table reports on some other key feature differences and similarities of the Fujifilm GFX 50S, the Panasonic GX800, and comparable cameras.

One feature that is present on the GFX 50S, but is missing on the GX800 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 GX800 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 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, both cameras under consideration feature an 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 Fujifilm GFX 50S and the Panasonic GX800 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 GFX 50S and the GX800 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 GX800 only has one slot. The GFX 50S supports UHS-II cards (on both slots), while the GX800 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 Fujifilm GFX 50S and Panasonic Lumix DMC-GX800 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 hotshoe, while the GX800 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Studio photographers will appreciate that the Fujifilm GFX 50S (unlike the GX800) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the GFX 50S and the GX800 are recent models that are part of the current product line-up. The GX800 replaced the earlier Panasonic GF7, 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 Fujifilm and Panasonic websites.
So what conclusions can be drawn? Which of the two cameras – the Fujifilm GFX 50S or the Panasonic GX800 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

- More affordable: Was introduced into a lower priced category (92 percent cheaper at launch).
- More modern: Was introduced somewhat (3 months) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the GFX 50S is the clear winner of the match-up (21 : 8 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 Fujifilm GFX 50S and the Panasonic GX800 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the GFX 50S or the GX800 perform in practice. 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 where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major 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.

The above review scores should be interpreted 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
