Fujifilm X20 versus Sony RX100

The Fujifilm X20 and the Sony Cyber-shot DSC-RX100 are two digital cameras that were officially introduced, respectively, in January 2013 and June 2012. Both the X20 and the RX100 are fixed lens compact cameras that are based on a 2/3 (X20) and an one-inch (RX100) sensor. The Fujifilm has a resolution of 12 megapixel, whereas the Sony provides 20 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 Sony RX100

The physical size and weight of the Fujifilm X20 and the Sony RX100 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 measures are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage 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 Sony RX100 is notably smaller (28 percent) than the Fujifilm X20. Moreover, the RX100 is markedly lighter (32 percent) than the X20. In this context, it is worth noting that neither the X20 nor the RX100 are weather-sealed.

Concerning battery life, the X20 gets 270 shots out of its NP-50 battery, while the RX100 can take 330 images on a single charge of its NP-BX1 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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 somewhat cheaper (by 8 percent) than the RX100 at launch, but both cameras fall into the same price category. 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 Sony RX100

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. 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 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 Sony RX100 an one-inch sensor. The sensor area in the RX100 is 100 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 3.9 and 2.7. The sensor in the X20 has a native 4:3 aspect ratio, while the one in the RX100 offers a 3:2 aspect.

Fujifilm X20 and Sony RX100 sensor measures

With 20MP, the RX100 offers a higher resolution than the X20 (12MP), but the RX100 nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 2.20μm for the X20) due to its larger sensor. However, the X20 is a somewhat more recent model (by 7 months) than the RX100, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the X20 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Many modern cameras cannot only take still pictures, but also record videos. 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 Sony RX100

Beyond body and sensor, cameras can and do differ across a range of features. For example, the X20 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the RX100 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Fujifilm X20, the Sony RX100, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the X20 and the RX100 have zoom lenses build in. The X20 has a 28-112mm f/2.0-2.8 optic and the RX100 offers a 28-100mm f/1.8-4.9 (focal lengths in full frame equivalent terms). Hence, the Fujifilm and Sony provide the same view at the wide-angle end, but the Sony has less tele-photo reach at the long end. The RX100 offers the faster maximum aperture.

Both the X20 and the RX100 have been discontinued, but can regularly be found used on eBay. The RX100 was replaced by the Sony RX100 II, while the X20 was followed by the Fujifilm X30.

Review summary: Fujifilm X20 vs Sony RX100

So how do things add up? Is the Fujifilm X20 better than the Sony RX100 or vice versa? The listing below highlights the relative strengths of the two models.


logo checkmark

Arguments in favor of the Fujifilm X20:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Easier framing: Has an optical viewfinder for image framing and settings control.
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (12 vs 10 flaps/sec) to capture the decisive moment.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • More modern: Is somewhat more recent (announced 7 months after the RX100).

logo checkmark

Reasons to prefer the Sony Cyber-shot DSC-RX100:

  • More detail: Has more megapixels (20 vs 12MP), which boosts linear resolution by 32%.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 460k dots).
  • Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/2.0).
  • More compact: Is smaller (102x58mm vs 117x70mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 113g or 32 percent) and is thus easier to take along.
  • Longer lasting: Gets more shots (330 versus 270) out of a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in June 2012).

If the count of individual advantages (bullet points above) is taken as a guide, the RX100 is the clear winner of the contest (10 : 6 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 06:10 RX100

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the X20 and the RX100 in practical situations. 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 following table reports the overall rankings of the cameras as published by some of the major camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
