Body comparison

The physical size and weight of the Fujifilm GFX 100 II and the Panasonic S1 II are illustrated 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 II vs Panasonic S1 II
Compare GFX 100 II versus S1 II top
Comparison GFX 100 II or S1 II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic S1 II is notably smaller (23 percent) than the Fujifilm GFX 100 II. Moreover, the S1 II is markedly lighter (22 percent) than the GFX 100 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 100 II gets 540 shots out of its Fujifilm NP-W235 battery, while the S1 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 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 naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The S1 II was launched at a markedly lower price (by 57 percent) than the GFX 100 II, 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. 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Fujifilm GFX 100 II features a medium format sensor and the Panasonic S1 II a full frame sensor. The sensor area in the S1 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 100 II has a native 4:3 aspect ratio, while the one in the S1 II offers a 3:2 aspect.

Fujifilm GFX 100 II and Panasonic S1 II sensor measures

With 101.8MP, the GFX 100 II offers a higher resolution than the S1 II (24MP), but the GFX 100 II has smaller individual pixels (pixel pitch of 3.76μm versus 5.97μm for the S1 II). Moreover, the S1 II is a somewhat more recent model (by 1 year and 8 months) than the GFX 100 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 100 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GFX 100 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 S1 II are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 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 100 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-S1 II are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.

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.

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

One feature that is present on the GFX 100 II, but is missing on the S1 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 S1 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 100 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 100 II and the Panasonic S1 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.

Concerning the storage of imaging data, both the GFX 100 II and the S1 II write their files to 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 100 II and Panasonic Lumix DC-S1 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 100 II and the S1 II are recent models that are part of the current product line-up. The GFX 100 II replaced the earlier Fujifilm GFX 100, while the S1 II followed on from the Panasonic S1. 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 conclusions can be drawn? Is the Fujifilm GFX 100 II better than the Panasonic S1 II or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Reasons to prefer the Fujifilm GFX 100 II:

  • More detail: Offers more megapixels (101.8 vs 24MP) with a 102% higher linear resolution.
  • Better video: Provides higher definition movie capture (8K/30p vs 6K/30p).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (9440k vs 5760k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (1.27x 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 (540 versus 350) on a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in September 2023).

ilogo

Advantages of the Panasonic Lumix DC-S1 II:

  • 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 (10 vs 8 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (134x102mm vs 152x117mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 230g or 22 percent) and is thus easier to take along.
  • More affordable: Was introduced into a lower priced category (57 percent cheaper at launch).
  • More modern: Was introduced somewhat (1 year and 8 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the GFX 100 II comes out slightly ahead of the S1 II (8 : 7 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

GFX 100 II 08:07 S1 II

How about other alternatives? Do the specifications of the Fujifilm GFX 100 II and the Panasonic S1 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 100 II and the S1 II 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 why hands-on reviews by experts 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 assessments were made in relation to similar cameras of the same technological generation. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
