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

An illustration of the physical size and weight of the Fujifilm X20 and the Fujifilm X100S is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size 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 – the X20 – represents 100 percent 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The camera’s price is obviously a critical decision-making factor. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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.

 

Sensor comparison: Fujifilm X20 vs Fujifilm X100S

The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 are more costly to manufacture and tend to lead to bigger and heavier cameras 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 many cameras. 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 are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, 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 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 table below summarizes some of the other core capabilities of the Fujifilm X20 and Fujifilm X100S in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or in the dpreview camera hub.

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 write their imaging data to SDXC cards.

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 how do things add up? Is the Fujifilm X20 better than the Fujifilm X100S or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Reasons to prefer 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).


Advantages 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 specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the X20 and the X100S in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is why hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
