Fujifilm X100S vs Leica S3

The Fujifilm X100S and the Leica S3 are two digital cameras that were announced, respectively, in January 2013 and September 2018. The X100S is a fixed lens compact, while the S3 is a DSLR. The cameras are based on an APS-C (X100S) and a medium format (S3) sensor. The Fujifilm has a resolution of 16 megapixels, whereas the Leica provides 64 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X100S and the Leica S3? 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 X100S and the Leica S3. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

The X100S can be obtained in two different colors (black, silver), while the S3 is only available in black.

Compare X100S versus S3 top
Comparison X100S or S3 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica S3 is considerably larger (104 percent) than the Fujifilm X100S. It is noteworthy in this context that the S3 is splash and dust-proof, while the X100S does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X100S has a lens built in, whereas the S3 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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 X100S was launched at a lower price than the S3, despite having a lens built in. 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.

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 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Fujifilm X100S features an APS-C sensor and the Leica S3 a medium format sensor. The sensor area in the S3 is 267 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 0.8. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Fujifilm X100S and Leica S3 sensor measures

With 64MP, the S3 offers a higher resolution than the X100S (16MP), but the S3 has smaller individual pixels (pixel pitch of 4.59μm versus 4.80μm for the X100S). Yet, the S3 is a much more recent model (by 5 years and 8 months) than the X100S, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. 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 Leica S3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S3 for good quality output (200 dots per inch) amounts to 49 x 32.7 inches or 124.5 x 83 cm, for very good quality (250 dpi) 39.2 x 26.1 inches or 99.6 x 66.4 cm, and for excellent quality (300 dpi) 32.7 x 21.8 inches or 83 x 55.3 cm. The corresponding values for the Fujifilm X100S are 24.5 x 16.3 inches or 62.2 x 41.5 cm for good quality, 19.6 x 13.1 inches or 49.7 x 33.2 cm for very good quality, and 16.3 x 10.9 inches or 41.5 x 27.6 cm for excellent quality prints.

The X100S has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Fujifilm X100S has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-25600. The corresponding ISO settings for the Leica S3 are ISO 100 to ISO 50000 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. The X100S uses Fujifilm's X-Trans layout of photosites, while the S3 employs the more common Bayer array.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the S3 provides a better video resolution than the X100S. It can shoot movie footage at 4K/24p, while the Fujifilm is limited to 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the X100S has an electronic viewfinder (2360k dots), while the S3 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the X100S offers a wider field of view (100%) than the one in the S3 (98%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the S3 has a higher magnification (0.87x vs 0.43x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Fujifilm X100S and Leica S3 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The X100S has one, while the S3 does not. While the built-in flash of the X100S is not very powerful, it can at times be useful as a fill-in light.

The X100S writes its imaging data to SDXC cards, while the S3 uses Compact Flash or SDXC cards. The S3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the X100S only has one slot. The S3 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the X100S can use UHS-I cards (up to 104 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 X100S and Leica S3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the S3 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the X100S does not provide wifi capability.

Studio photographers will appreciate that the Leica S3 (unlike the X100S) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Travel and landscape photographers will find it useful that the S3 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

The S3 is a recent model that features in the current product line-up of Leica. In contrast, the X100S has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the X100S was succeeded by the Fujifilm X100T. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Fujifilm and Leica websites.

Review summary

So what is the bottom line? Is the Fujifilm X100S better than the Leica S3 or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Reasons to prefer the Fujifilm X100S:

  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More complete view: Has a viewfinder with a larger field of view (100% vs 98%).
  • Faster burst: Shoots at higher frequency (6 vs 3 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with a built-in lens, while the S3 requires a separate lens.
  • More compact: Is smaller (127x74mm vs 160x120mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the S3).
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More heavily discounted: Has been available for much longer (launched in January 2013).

ilogo

Arguments in favor of the Leica S3:

  • More detail: Has more megapixels (64 vs 16MP), which boosts linear resolution by 100%.
  • Better image quality: Is equipped with a larger and more technologically advanced 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 video: Provides higher definition movie capture (4K/24p vs 1080/60p).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.87x vs 0.43x).
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (922k vs 460k dots).
  • More flexible: Makes it possible to change lenses and thus to use specialty optics.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Easier geotagging: Features an internal GPS sensor to log localization data.
  • Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
  • More modern: Reflects 5 years and 8 months of technical progress since the X100S launch.

If the count of relative strengths (bullet points above) is taken as a measure, the S3 is the clear winner of the contest (23 : 10 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.

X100S 10:23 S3

How about other alternatives? Do the specifications of the Fujifilm X100S and the Leica S3 place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact Camera and Best DSLR Camera listings 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the X100S or the S3. 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 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.

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

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
