Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X-T100 and the Panasonic Lumix DC-S1? 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.
An illustration of the physical size and weight of the Fujifilm X-T100 and the Panasonic S1 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 dimensions are rounded to the nearest millimeter.
The X-T100 can be obtained in three different colors (black, silver, gold), while the S1 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic S1 is considerably larger (63 percent) than the Fujifilm X-T100. Moreover, the S1 is substantially heavier (127 percent) than the X-T100. It is noteworthy in this context that the S1 is splash and dust-proof, while the X-T100 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.
Concerning battery life, the X-T100 gets 430 shots out of its NP-W126S battery, while the S1 can take 400 images on a single charge of its DMW-BLJ31 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

Any camera decision will obviously take relative prices into account. 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 X-T100 was launched at a markedly lower price (by 76 percent) than the S1, 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.
The size of the sensor inside a digital camera is one of the key determinants 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Fujifilm X-T100 features an APS-C sensor and the Panasonic S1 a full frame sensor. The sensor area in the S1 is 130 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Even though the S1 has a larger sensor, both cameras offer the same resolution of 24 megapixels. This implies that the S1 has a lower pixel density and larger individual pixels (with a pixel pitch of 5.94μm versus 3.92μm for the X-T100), which gives it a potential advantage in terms of light gathering capacity. In addition, the S1 is a somewhat more recent model (by 8 months) than the X-T100, and its sensor might have benefitted from technological advances during this time. Coming back to sensor resolution, it should be mentioned that the S1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The X-T100 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
Unlike the X-T100, the S1 has the capacity to capture high quality composite images (96MP) 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 X-T100 has a native sensitivity range from ISO 200 to ISO 12800, which can be extended to ISO 100-51200. The corresponding ISO settings for the Panasonic Lumix DC-S1 are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.
For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the S1 provides a faster frame rate than the X-T100. It can shoot movie footage at 4K/60p, while the Fujifilm is limited to 4K/15p.
Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the S1 offers a substantially higher resolution than the one in the X-T100 (5760k vs 2360k dots). The following table reports on some other key feature differences and similarities of the Fujifilm X-T100, the Panasonic S1, and comparable cameras.
One difference between the cameras concerns the presence of an on-board flash. The X-T100 has one, while the S1 does not. While the built-in flash of the X-T100 is not very powerful, it can at times be useful as a fill-in light.The X-T100 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the S1 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 X-T100 and the Panasonic S1 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 X-T100 writes its imaging data to SDXC cards, while the S1 uses SDHC or XQD cards. The S1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the X-T100 only has one slot. The S1 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the X-T100 can use UHS-I cards (up to 104 MB/s).
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 X-T100 and Panasonic Lumix DC-S1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the S1 has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The X-T100 lacks such a headphone port.
Studio photographers will appreciate that the Panasonic S1 (unlike the X-T100) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The S1 is a recent model that features in the current product line-up of Panasonic. In contrast, the X-T100 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the X-T100 was succeeded by the Fujifilm X-T200. 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.
So what conclusions can be drawn? Which of the two cameras – the Fujifilm X-T100 or the Panasonic S1 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

- More modern: Was introduced somewhat (8 months) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the S1 is the clear winner of the contest (23 : 8 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. 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.
How about other alternatives? Do the specifications of the Fujifilm X-T100 and the Panasonic S1 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 says little about, for example, the shooting experience and imaging performance of the X-T100 and the S1 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.
This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

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. Thus, a score needs to be put into the context of the launch date and the launch price 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.
