Body comparison

An illustration of the physical size and weight of the Fujifilm GFX 100S II and the Panasonic S1R II 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 size dimensions are rounded to the nearest millimeter.

Compare GFX 100S II versus S1R II top
Comparison GFX 100S II or S1R II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic S1R II is notably smaller (12 percent) than the Fujifilm GFX 100S II. Moreover, the S1R II is markedly lighter (10 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 II can take 350 images on a single charge of its Panasonic DMW-BLK22 power pack. 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.

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

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 S1R II was launched at a markedly lower price (by 34 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.

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 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the 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 Fujifilm GFX 100S II features a medium format sensor and the Panasonic S1R II a full frame sensor. The sensor area in the S1R II is 41 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 II offers a 3:2 aspect.

Fujifilm GFX 100S II and Panasonic S1R II sensor measures

With 101.8MP, the GFX 100S II offers a higher resolution than the S1R II (44.2MP), but the GFX 100S II has smaller individual pixels (pixel pitch of 3.76μm versus 4.40μm for the S1R II). Moreover, the S1R II is a somewhat more recent model (by 11 months) than the GFX 100S II, and its sensor might have benefitted from technological advances during this time that further 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 II are 40.7 x 27.1 inches or 103.4 x 68.9 cm for good quality, 32.6 x 21.7 inches or 82.7 x 55.1 cm for very good quality, and 27.1 x 18.1 inches or 69 x 45.9 cm for excellent quality prints.

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 II are ISO 80 to ISO 51200, with the possibility to increase the ISO range to 40-102400.

Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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 S1R II provides a better video resolution than the GFX 100S II. It can shoot movie footage at 8K/30p, while the Fujifilm is limited to 4K/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The GFX 100S II and the S1R II are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 5760k dots. The adjacent table lists some of the other core features of the Fujifilm GFX 100S II and Panasonic S1R II along with similar information for a selection of comparators.

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

One feature that is present on the GFX 100S II, but is missing on the S1R II 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 S1R II 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 II 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 II and the Panasonic S1R II 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 II uses CFexpress (type B) or SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. Both cameras support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s.

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 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Both the GFX 100S II and the S1R II are recent models that are part of the current product line-up. The GFX 100S II replaced the earlier Fujifilm GFX 100S, while the S1R II followed on from the Panasonic S1R. 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 how do things add up? Which of the two cameras – the Fujifilm GFX 100S II or the Panasonic S1R II – 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.

ilogo

Advantages of the Fujifilm GFX 100S II:

  • More detail: Offers more megapixels (101.8 vs 44.2MP) with a 49% higher linear resolution.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.84x vs 0.78x).
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • More detailed LCD: Has a higher resolution rear screen (2360k vs 1840k dots).
  • Longer lasting: Can take more shots (530 versus 350) on a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in May 2024).

ilogo

Arguments in favor of the Panasonic Lumix DC-S1R II:

  • Better video: Provides higher definition movie capture (8K/30p vs 4K/30p).
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • 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 compact: Is smaller (134x102mm vs 150x104mm) and will fit more readily into a bag.
  • 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 (34 percent cheaper at launch).
  • More modern: Was introduced somewhat (11 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the S1R II emerges as the winner of the match-up (8 : 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.

GFX 100S II 06:08 S1R II

How about other alternatives? Do the specifications of the Fujifilm GFX 100S II and the Panasonic S1R II 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 II 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 why expert reviews are important. 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.

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

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
