Fujifilm X100 versus Fujifilm X20

The Fujifilm FinePix X100 and the Fujifilm X20 are two digital cameras that were officially introduced, respectively, in September 2010 and January 2013. Both the X100 and the X20 are fixed lens compact cameras that are based on an APS-C (X100) and a 2/3 sensor. The X100 has a resolution of 12.2 megapixel, whereas the X20 provides 12 MP.

Body comparison

An illustration of the physical size and weight of the Fujifilm X100 and the Fujifilm X20 is provided in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter. You can also toggle the display 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 X100 – represents the basis or 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 X20 is notably smaller (13 percent) than the Fujifilm X100. Moreover, the X20 is markedly lighter (21 percent) than the X100. In this context, it is worth noting that neither the X100 nor the X20 are weather-sealed.

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. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed 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 50 percent) than the X100, 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

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 X100 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 X100 has a native 3:2 aspect ratio, while the one in the X20 offers a 4:3 aspect.

Sensor size

With 12.2MP, the X100 offers a higher resolution than the X20 (12MP), but the X100 nevertheless has larger individual pixels (pixel pitch of 5.53μm versus 2.20μm for the X20) due to its larger sensor. However, the X20 is a somewhat more recent model (by 2 years and 3 months) than the X100, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. 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.

Sensor resolution

For most 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 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, but the X20 provides a better video resolution than the X100. It can shoot movie footage at 1080/60p, while the X100 is limited to 720/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the X100 has an electronic viewfinder (1440k 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 X100 and Fujifilm X20 along with similar information for a selection of comparators. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

The X20 is equipped with a zoom lens, while the X100 comes with a build-in prime. The X20 has a 28-112mm f/2.0-2.8 optic and the X100 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 X100. Both cameras offer the same maximum aperture.

Both the X100 and the X20 have been discontinued, but can regularly be found used on ebay. The X100 was replaced by the Fujifilm X100S, while the X20 was followed by the Fujifilm X30.

Summary

So what conclusions can be drawn? Is the Fujifilm X100 better than the Fujifilm X20 or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Reasons to prefer the Fujifilm FinePix X100:

  • 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: Can take more shots (300 versus 270) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in September 2010).

Arguments in favor of the Fujifilm X20:

  • Better video: Provides higher definition movie capture (1080/60p vs 720/30p).
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Faster burst: Shoots at higher frequency (12 vs 5 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 126x75mm) 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.
  • More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
  • More modern: Reflects 2 years and 3 months of technical progress since the X100 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the X20 is the clear winner of the contest (8 : 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.

X100 04:08 X20

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 X100 or the X20 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 adjacent table relays the overall verdicts of several of the most popular camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The review scores listed above should be treated with care, though. The ratings are only valid when refering 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
