Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X100S and the Fujifilm FinePix X100? 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

An illustration of the physical size and weight of the Fujifilm X100S and the Fujifilm X100 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.

The X100S can be obtained in two different colors (black, silver), while the X100 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 Fujifilm X100S and the Fujifilm X100 are of equal size. Similarly, the two cameras are very close in terms of weight. In this context, it is worth noting that neither the X100S nor the X100 are weather-sealed.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The X100 was somewhat cheaper (by 8 percent) than the X100S at launch, but both cameras fall into the same price category. 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 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. 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.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the X100 is 1 percent bigger. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

In terms of chip-set technology, the X100S uses a more advanced image processing engine (EXR Processor II) than the X100 (EXR Processor), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a slightly smaller sensor, the Fujifilm X100S offers a higher resolution of 16 megapixels, compared with 12.2 MP of the Fujifilm X100. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.80μm versus 5.53μm for the X100). However, it should be noted that the X100S is much more recent (by 2 years and 3 months) than the X100, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the X100S has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Fujifilm X100S implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X100S for good quality output (200 dots per inch) amounts to 24.5 x 16.3 inches or 62.2 x 41.5 cm, for very good quality (250 dpi) 19.6 x 13.1 inches or 49.7 x 33.2 cm, and for excellent quality (300 dpi) 16.3 x 10.9 inches or 41.5 x 27.6 cm. The corresponding values for the Fujifilm X100 are 21.4 x 14.2 inches or 54.5 x 36.2 cm for good quality, 17.2 x 11.4 inches or 43.6 x 28.9 cm for very good quality, and 14.3 x 9.5 inches or 36.3 x 24.1 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 Fujifilm FinePix X100 are ISO 200 to ISO 6400, with the possibility to increase the ISO range to 100-12800.

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 X100 employs the more common Bayer array.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

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 X100S provides a higher video resolution than the X100. It can shoot video footage at 1080/60p, while the X100 is limited to 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the X100S offers a substantially higher resolution than the one in the X100 (2360k vs 1440k dots). The following table reports on some other key feature differences and similarities of the Fujifilm X100S, the Fujifilm X100, and comparable cameras.

Both the X100S and the X100 have built-in prime lenses. Both optics have identical focal length and aperture specifications (23mm f/2.0). Both cameras offer the same maximum aperture.

Concerning the storage of imaging data, both the X100S and the X100 write their files to SDXC cards. The X100S supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the X100 cannot take advantage of Ultra High Speed SD cards.

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 Fujifilm FinePix X100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the X100S and the X100 have been discontinued, but can regularly be found used on ebay. The X100 was replaced by the Fujifilm X100S, while the X100S was followed by the Fujifilm X100T. Further information on the features and operation of the X100S and X100 can be found, respectively, in the Fujifilm X100S Manual (free pdf) or the online Fujifilm X100 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Fujifilm X100S and the Fujifilm X100? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Fujifilm X100S:

• More detail: Offers more megapixels (16 vs 12.2MP) with a 14% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better jpgs: Has a more modern image processing engine (EXR Processor II vs EXR Processor).
• Better video: Provides higher definition movie capture (1080/60p vs 720/30p).
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
• Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 2 years and 3 months of technical progress since the X100 launch.

Arguments in favor of the Fujifilm FinePix X100:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.50x vs 0.43x).
• More heavily discounted: Has been around for much longer (launched in September 2010).

If the count of individual advantages (bullet points above) is taken as a guide, the X100S is the clear winner of the match-up (9 : 3 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 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 X100S and the Fujifilm X100 place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact 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 remains incomplete and does no justice, for example, to the way the X100S or the X100 perform in practice. 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 ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
