Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will naturally be influenced heavily by the price. 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 40 percent) than the RX100 IV, 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Sony RX100 IV features an one-inch sensor and the Fujifilm X20 a 2/3 sensor. The sensor area in the X20 is 50 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 3.9. The sensor in the RX100 IV has a native 3:2 aspect ratio, while the one in the X20 offers a 4:3 aspect.

Sony RX100 IV and Fujifilm X20 sensor measures

With 20MP, the RX100 IV offers a higher resolution than the X20 (12MP), but the RX100 IV nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 2.20μm for the X20) due to its larger sensor. Moreover, the RX100 IV is a much more recent model (by 2 years and 5 months) than the X20, and its sensor will 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 the X20 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony RX100 IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX100 IV for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Fujifilm X20 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The X20 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Sony Cyber-shot DSC-RX100 IV has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 80-25600. The corresponding ISO settings for the Fujifilm X20 are ISO 100 to ISO 12800 (no boost).

In terms of underlying technology, the RX100 IV is build around a BSI-CMOS sensor, while the X20 uses a CMOS imager. Like most digital cameras, the RX100 IV uses a Bayer filter for capturing RGB colors on a square grid of photosensors. In contrast, the X20 employs a more randomized X-Trans layout of photosites, which according to Fujifilm helps to minimize moiré.

RX100 IV versus X20 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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").

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.
The RX100 IV has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the X20 does not have a selfie-screen.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the RX100 IV is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

Both the RX100 IV and the X20 have zoom lenses built in. The RX100 IV has a 24-70mm f/1.8-2.8 optic and the X20 offers a 28-112mm f/2.0-2.8 (focal lengths in full frame equivalent terms). Hence, the Sony provides a wider angle of view at the short end than the Fujifilm, but less tele-photo reach at the long end. The RX100 IV offers the faster maximum aperture.

The RX100 IV writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the X20 uses SDXC cards. The RX100 IV supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the X20 cannot take advantage of Ultra High Speed SD cards.

  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • More affordable: Was introduced into a lower priced category (40 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in January 2013).

If the count of relative strengths (bullet points above) is taken as a measure, the RX100 IV is the clear winner of the match-up (23 : 8 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

RX100 IV 23:08 X20

How about other alternatives? Do the specifications of the Sony RX100 IV and the Fujifilm X20 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the RX100 IV and the X20 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
