Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm GFX 100S II and the Panasonic Lumix DC-S1R? 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
The side-by-side display below illustrates the physical size and weight of the Fujifilm GFX 100S II and the Panasonic S1R. 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 Panasonic S1R is somewhat larger (5 percent) than the Fujifilm GFX 100S II. Moreover, the S1R is markedly heavier (15 percent) than the GFX 100S II. 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 100S II gets 530 shots out of its Fujifilm NP-W235 battery, while the S1R can take 380 images on a single charge of its Panasonic DMW-BLJ31 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The price is, of course, an important factor in any camera decision. 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 S1R was launched at a markedly lower price (by 26 percent) than the GFX 100S II, 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 sensor inside a digital camera is one of the key determinants 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. 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 II features a medium format sensor and the Panasonic S1R a full frame sensor. The sensor area in the S1R is 40 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 0.79 and 1.0. The sensor in the GFX 100S II has a native 4:3 aspect ratio, while the one in the S1R offers a 3:2 aspect.

With 101.8MP, the GFX 100S II offers a higher resolution than the S1R (46.7MP), but the GFX 100S II has smaller individual pixels (pixel pitch of 3.76μm versus 4.30μm for the S1R). However, the GFX 100S II is a much more recent model (by 5 years and 3 months) than the S1R, 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 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GFX 100S II 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 Panasonic S1R are 41.8 x 27.9 inches or 106.3 x 70.9 cm for good quality, 33.5 x 22.3 inches or 85 x 56.7 cm for very good quality, and 27.9 x 18.6 inches or 70.8 x 47.3 cm for excellent quality prints.
The GFX 100S II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
Both cameras have the capacity to capture high quality composite images by combining multiple shots after shifting the 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 II 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 DC-S1R are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-51200.
In terms of underlying technology, the GFX 100S II is build around a BSI-CMOS sensor, while the S1R uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

For many cameras, data on sensor performance has been reported by DXO Mark. 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").

| Note: *) 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, 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 II and the Panasonic S1R 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 GFX 100S II writes its imaging data to SDXC cards, while the S1R uses SDXC or XQD cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. Moreover, both the GFX 100S II and the S1R support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s, on both slots.
Connectivity comparison
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 100S II and Panasonic Lumix DC-S1R and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The GFX 100S II is a recent model that features in the current product line-up of Fujifilm. In contrast, the S1R has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the S1R was succeeded by the Panasonic S1R II. 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.
Review summary
So what is the bottom line? Which of the two cameras – the Fujifilm GFX 100S II or the Panasonic S1R – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Fujifilm GFX 100S II:
- More detail: Offers more megapixels (101.8 vs 46.7MP) with a 45% higher linear resolution.
- Better image quality: Features a larger and more technologically advanced imaging sensor.
- Richer colors: The sensor size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.84x vs 0.78x).
- More detailed LCD: Has a higher resolution rear screen (2360k vs 2100k dots).
- Less heavy: Is lighter (by 133g or 13 percent) and hence easier to carry around.
- Longer lasting: Can take more shots (530 versus 380) on a single battery charge.
- Faster data transfer: Supports a more advanced USB protocol (3.2 vs 3.1).
- More modern: Reflects 5 years and 3 months of technical progress since the S1R launch.

Advantages of the Panasonic Lumix DC-S1R:
- Better video: Provides higher movie framerates (4K/60p versus 4K/30p).
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (9 vs 7 flaps/sec) to capture the decisive moment.
- More solid recording: Has a full-sized HDMI port for a sturdy connection to an external recorder.
- More affordable: Was introduced into a lower priced category (26 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in February 2019).
If the number of relative strengths (bullet points above) is taken as a guide, the GFX 100S II is the clear winner of the match-up (12 : 6 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 100S II and the Panasonic S1R 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 100S II and the S1R in practical situations. 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.
Expert reviews
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], 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
