Fujifilm X20 versus Fujifilm X100S

The Fujifilm X20 and the Fujifilm X100S are two digital cameras that were announced in January 2013. Both the X20 and the X100S are fixed lens compact cameras that are based on a 2/3 (X20) and an APS-C (X100S) sensor. The X20 has a resolution of 12 megapixel, whereas the X100S provides 16 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Fujifilm X20 vs Fujifilm X100S

The physical size and weight of the Fujifilm X20 and the Fujifilm X100S are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the X20 – represents the basis for the calculations across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm X100S is notably larger (15 percent) than the Fujifilm X20. Moreover, the X100S is markedly heavier (26 percent) than the X20. In this context, it is worth noting that neither the X20 nor the X100S are weather-sealed.

Concerning battery life, the X20 gets 270 shots out of its NP-50 battery, while the X100S can take 330 images on a single charge of its NP-95 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table.

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.

 

Sensor comparison: Fujifilm X20 vs Fujifilm X100S

The size of the imaging sensor is a crucial determinant 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 X20 features a 2/3 sensor and the Fujifilm X100S an APS-C sensor. The sensor area in the X100S is 534 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 3.9 and 1.5. The sensor in the X20 has a native 4:3 aspect ratio, while the one in the X100S offers a 3:2 aspect.

Fujifilm X20 and Fujifilm X100S sensor measures

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.

X20 versus X100S MP

Consistent information on actual sensor performance is available from DXO Mark for most cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). 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 are not only capable of taking still images, but also of capturing video footage. 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).

 

Feature comparison: Fujifilm X20 vs Fujifilm X100S

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 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 adjacent table lists some of the other core features of the Fujifilm X20 and Fujifilm X100S along with similar information for a selection of comparators. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The X20 is equipped with a zoom lens, while the X100S comes with a build-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.

Both the X20 and the X100S have been discontinued, but can regularly be found used on eBay. The X20 was replaced by the Fujifilm X30, while the X100S was followed by the Fujifilm X100T.

Review summary: Fujifilm X20 vs Fujifilm X100S

So what conclusions can be drawn? Is the Fujifilm X20 better than the Fujifilm X100S or vice versa? The listing below highlights the relative strengths of the two models.


Advantages 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 thus needs less room in the bag.
  • Less heavy: Is lighter (by 92g or 21 percent) and hence easier to carry around.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More affordable: Was introduced into a lower priced category (54 percent cheaper at launch).


Arguments in favor of the Fujifilm X100S:

  • More detail: Has more megapixels (16 vs 12MP), which boosts linear resolution by 18%.
  • Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Longer lasting: Gets more shots (330 versus 270) out of a single battery charge.

If the number of relative strengths (bullet points above) is taken as a guide, the X20 emerges as the winner of the contest (7 : 4 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.

X20 07:04 X100S

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the X20 or the X100S handle or 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. This is why hands-on reviews by experts are important.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
