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 (X20) sensor. The X100 has a resolution of 12.2 megapixel, whereas the X20 provides 12 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 X100 vs Fujifilm X20

The physical size and weight of the Fujifilm X100 and the Fujifilm X20 are illustrated in the side-by-side display below. 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. 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 X100 – 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 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.

Concerning battery life, the X100 gets 300 shots out of its NP-95 battery, while the X20 can take 270 images on a single charge of its NP-50 power pack.

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 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: Fujifilm X100 vs Fujifilm X20

The size of the imaging sensor is a crucial determinant 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. 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.

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.

Fujifilm X100 and Fujifilm X20 sensor measures

With 12.2MP, the X100 offers a slightly 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.

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 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: Fujifilm X100 vs Fujifilm X20

Apart from body and sensor, cameras can and do differ across a variety 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 following table reports on some other key feature differences and similarities of the Fujifilm X100, the Fujifilm X20, and comparable cameras. The full specs-sheets can be found in the camera manual or, 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.

Review summary: Fujifilm X100 vs Fujifilm X20

So how do things add up? Which of the two cameras – the Fujifilm X100 or the Fujifilm X20 – has the upper hand? The listing below highlights the relative strengths of the two models.


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.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • 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 relative strengths (bullet points above) is taken as a measure, the X20 is the clear winner of the contest (9 : 4 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.

X100 04:09 X20

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the X100 and the X20 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 where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
