Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X100S and the Fujifilm X20? 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.
The side-by-side display below illustrates the physical size and weight of the Fujifilm X100S and the Fujifilm X20. 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.
Both cameras are available in two different colors (black, silver).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm X20 is notably smaller (13 percent) than the Fujifilm X100S. Moreover, the X20 is markedly lighter (21 percent) than the X100S. In this context, it is worth noting that neither the X100S nor the X20 are weather-sealed.

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 X20 was launched at a markedly lower price (by 54 percent) than the X100S, 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 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 X100S features an APS-C sensor and the Fujifilm X20 a 2/3 sensor. The sensor area in the X20 is 84 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 3.9. The sensor in the X100S has a native 3:2 aspect ratio, while the one in the X20 offers a 4:3 aspect.
With 16MP, the X100S offers a higher resolution than the X20 (12MP), but the X100S nevertheless has larger individual pixels (pixel pitch of 4.80μm versus 2.20μm for the X20) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. 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 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 X20 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.
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 X20 are ISO 100 to ISO 12800 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-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, and both provide the same movie specifications (1080/60p).
Apart from body and sensor, cameras can and do differ across a range of features. For example, the X100S has an electronic viewfinder (2360k dots), while the X20 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 following table reports on some other key feature differences and similarities of the Fujifilm X100S, the Fujifilm X20, and comparable cameras.
|Canon G1 X||optical||n||3.0||922||Swivel||n||1/4000s||1.9||Y||Y|
|Leica X Typ 113||optional||n||3.0||920||fixed||n||1/2000s||5.0||Y||n|
|Nikon Coolpix A||optional||n||3.0||921||fixed||n||1/2000s||4.0||Y||n|
The X20 is equipped with a zoom lens, while the X100S comes with a built-in prime. The X20 has a 28-112mm f/2.0-2.8 optic and the X100S offers a 35mm f/2.0 (focal lengths in full frame equivalent terms). Hence, the X20 provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the X100S. Both cameras offer the same maximum aperture.
Concerning the storage of imaging data, both the X100S and the X20 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 X20 cannot take advantage of Ultra High Speed SD cards.
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 X20 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the X100S and the X20 have been discontinued, but can regularly be found used on eBay. The X100S was replaced by the Fujifilm X100T, while the X20 was followed by the Fujifilm X30. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Fujifilm website.
So how do things add up? Which of the two cameras – the Fujifilm X100S or the Fujifilm X20 – 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.
Reasons to prefer the Fujifilm X100S:
- More detail: Offers more megapixels (16 vs 12MP) with a 18% higher linear resolution.
- Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
- Richer colors: The pixel size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
- More framing info: Has an electronic viewfinder that displays shooting data.
- Longer lasting: Can take more shots (330 versus 270) on a single battery charge.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
Arguments in favor of the Fujifilm X20:
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Faster burst: Shoots at higher frequency (12 vs 6 flaps/sec) to capture the decisive moment.
- Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
- More compact: Is smaller (117x70mm vs 127x74mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 92g or 21 percent) and is thus easier to take along.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More affordable: Was introduced into a lower priced category (54 percent cheaper at launch).
If the number of relative strengths (bullet points above) is taken as a guide, the X100S comes out slightly ahead of the X20 (8 : 7 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 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the X100S or the X20 perform in practice. 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 where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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 above review scores should be interpreted 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. 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, please note that some of the review sites have changed their methodology and reporting over time.
