Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm GFX 100 and the Fujifilm GFX 100S? 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.

Body comparison

An illustration of the physical size and weight of the Fujifilm GFX 100 and the Fujifilm GFX 100S is provided in the side-by-side display below. 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.

Size Fujifilm GFX 100 vs Fujifilm GFX 100S
Compare GFX 100 versus GFX 100S top
Comparison GFX 100 or GFX 100S rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm GFX 100S is considerably smaller (31 percent) than the Fujifilm GFX 100. Moreover, the GFX 100S is markedly lighter (32 percent) than the GFX 100. 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 GFX 100 gets 800 shots out of its NP-T125 battery, while the GFX 100S can take 460 images on a single charge of its NP-W235 power pack. As can be seen in the images above, the GFX 100 has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

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.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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 GFX 100S was launched at a markedly lower price (by 40 percent) than the GFX 100, 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 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.

Both cameras under consideration feature a medium format sensor and have a format factor (sometimes also referred to as "crop factor") of 0.79. Within the spectrum of camera sensors, this places the review cameras among the large-sensor cameras that aim for top notch image quality. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Technology-wise, the GFX 100S uses a more advanced image processing engine (X-Processor 4) than the GFX 100 (X-Processor 4), with benefits for noise reduction, color accuracy, and processing speed.

Fujifilm GFX 100 and Fujifilm GFX 100S sensor measures

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 101.8 megapixels. This similarity in sensor specs implies that both the GFX 100 and the GFX 100S have the same pixel density, as well as the same pixel size. It should, however, be noted that the GFX 100S is a somewhat more recent model (by 1 year and 8 months) than the GFX 100, and its sensor might have benefitted from technological advances during this time. 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 Fujifilm GFX 100 has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 50-102400. The Fujifilm GFX 100S offers exactly the same ISO settings.

GFX 100 versus GFX 100S MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the GFX 100S has an electronic viewfinder (3690k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GFX 100 relies on live view and the rear LCD for framing. That said, the GFX 100 can be equipped with an optional viewfinder – the EVF-GFX2. The table below summarizes some of the other core capabilities of the Fujifilm GFX 100 and Fujifilm GFX 100S in connection with corresponding information for a sample of similar cameras.

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 100 and the Fujifilm GFX 100S 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 100 and the GFX 100S write their files to SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. Moreover, both the GFX 100 and the GFX 100S support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s, on both slots.

Review summary

So what conclusions can be drawn? Is the Fujifilm GFX 100 better than the Fujifilm GFX 100S or vice versa? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Fujifilm GFX 100:

  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Longer lasting: Can take more shots (800 versus 460) on a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in May 2019).


Reasons to prefer the Fujifilm GFX 100S:

  • Better jpgs: Has a more modern image processing engine (X-Processor 4 vs X-Processor 4).
  • Easier framing: Has an electronic viewfinder for image composition and settings control.
  • More flexible LCD: Has a full-flex screen for odd-angle shots in portrait or landscape orientation.
  • More compact: Is smaller (150x104mm vs 156x144mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 420g or 32 percent) and is thus easier to take along.
  • Faster data transfer: Supports a more advanced USB protocol (3.2 vs 3.1).
  • More affordable: Was introduced into a lower priced category (40 percent cheaper at launch).
  • More modern: Was introduced somewhat (1 year and 8 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the GFX 100S is the clear winner of the contest (8 : 3 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 100 03:08 GFX 100S

How about other alternatives? Do the specifications of the Fujifilm GFX 100 and the Fujifilm GFX 100S 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the GFX 100 and the GFX 100S in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

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], 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.

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

Care should be taken when interpreting the review scores above, 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
