Body comparison

The side-by-side display below illustrates the physical size and weight of the Fujifilm GFX 100S and the Fujifilm X-S20. 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.

Compare GFX 100S versus X-S20 top
Comparison GFX 100S or X-S20 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm X-S20 is considerably smaller (30 percent) than the Fujifilm GFX 100S. Moreover, the X-S20 is substantially lighter (45 percent) than the GFX 100S. It is worth mentioning in this context that the GFX 100S is splash and dust resistant, while the X-S20 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 battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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 obviously take relative prices into account. 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 X-S20 was launched at a markedly lower price (by 78 percent) than the GFX 100S, 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.

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 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 Fujifilm GFX 100S features a medium format sensor and the Fujifilm X-S20 an APS-C sensor. The sensor area in the X-S20 is 75 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 0.79 and 1.5. The sensor in the GFX 100S has a native 4:3 aspect ratio, while the one in the X-S20 offers a 3:2 aspect.

Fujifilm GFX 100S and Fujifilm X-S20 sensor measures

With 101.8MP, the GFX 100S offers a higher resolution than the X-S20 (26MP), but the GFX 100S nevertheless has the same individual pixel size (pixel pitch of 3.76μm) as the X-S20 due to its larger sensor. Moreover, the X-S20 is a much more recent model (by 2 years and 3 months) than the GFX 100S, and its sensor will 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 100S implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GFX 100S for good quality output (200 dots per inch) amounts to 58.2 x 43.7 inches or 147.9 x 110.9 cm, for very good quality (250 dpi) 46.6 x 34.9 inches or 118.3 x 88.8 cm, and for excellent quality (300 dpi) 38.8 x 29.1 inches or 98.6 x 74 cm. The corresponding values for the Fujifilm X-S20 are 31.2 x 20.8 inches or 79.2 x 52.8 cm for good quality, 25 x 16.6 inches or 63.4 x 42.3 cm for very good quality, and 20.8 x 13.9 inches or 52.8 x 35.2 cm for excellent quality prints.

Unlike the X-S20, the GFX 100S has the capacity to capture high quality composite images (YESMP) 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 Fujifilm GFX 100S 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 Fujifilm X-S20 are ISO 160 to ISO 12800, with the possibility to increase the ISO range to 80-51200.

Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensors. Like most digital cameras, the GFX 100S uses a Bayer filter for capturing RGB colors on a square grid of photosensors. In contrast, the X-S20 employs a more randomized X-Trans layout of photosites, which according to Fujifilm helps to minimize moiré.

GFX 100S versus X-S20 MP

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").

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One feature that is present on the GFX 100S, but is missing on the X-S20 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 X-S20 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 100S 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 100S and the Fujifilm X-S20 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 100S and the X-S20 write their files to SDXC cards. The GFX 100S features dual card slots, which can be very useful in case a memory card fails. In contrast, the X-S20 only has one slot. Both cameras support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s.

Studio photographers will appreciate that the Fujifilm GFX 100S (unlike the X-S20) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the GFX 100S and the X-S20 are recent models that are part of the current product line-up. The GFX 100S replaced the earlier Fujifilm GFX 100, while the X-S20 followed on from the Fujifilm X-S10. Further information on the features and operation of the GFX 100S and X-S20 can be found, respectively, in the Fujifilm GFX 100S Manual (free pdf) or the online Fujifilm X-S20 Manual.

Review summary

So what is the bottom line? Is the Fujifilm GFX 100S better than the Fujifilm X-S20 or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Reasons to prefer the Fujifilm GFX 100S:

  • More detail: Offers more megapixels (101.8 vs 26MP) with a 94% higher linear resolution.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
  • Richer colors: The pixel size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (3690k vs 2360k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.77x vs 0.62x).
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (2360k vs 1840k dots).
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been available for much longer (launched in January 2021).


Arguments in favor of the Fujifilm X-S20:

  • Better video: Provides higher movie framerates (4K/60p versus 4K/30p).
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (8 vs 5 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (128x85mm vs 150x104mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 409g or 45 percent) and is thus easier to take along.
  • Longer lasting: Gets more shots (750 versus 460) out of a single battery charge.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (78 percent cheaper at launch).
  • More modern: Reflects 2 years and 3 months of technical progress since the GFX 100S launch.

If the count of individual advantages (bullet points above) is taken as a guide, the GFX 100S is the clear winner of the match-up (15 : 9 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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.

GFX 100S 15:09 X-S20

How about other alternatives? Do the specifications of the Fujifilm GFX 100S and the Fujifilm X-S20 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 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 GFX 100S or the X-S20. 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.

Expert reviews

This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

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

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 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.
