Fujifilm X20 vs Sony RX100 IV
The Fujifilm X20 and the Sony Cyber-shot DSC-RX100 IV are two digital cameras that were officially introduced, respectively, in January 2013 and June 2015. Both the X20 and the RX100 IV are fixed lens compact cameras that are based on a 2/3 (X20) and an one-inch (RX100 IV) sensor. The Fujifilm has a resolution of 12 megapixels, whereas the Sony provides 20 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X20 and the Sony Cyber-shot DSC-RX100 IV? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
The side-by-side display below illustrates the physical size and weight of the Fujifilm X20 and the Sony RX100 IV. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.
The X20 can be obtained in two different colors (black, silver), while the RX100 IV is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX100 IV is notably smaller (28 percent) than the Fujifilm X20. Moreover, the RX100 IV is markedly lighter (16 percent) than the X20. In this context, it is worth noting that neither the X20 nor the RX100 IV are weather-sealed.
Concerning battery life, the X20 gets 270 shots out of its NP-50 battery, while the RX100 IV can take 280 images on a single charge of its NP-BX1 power pack. The power pack in the RX100 IV can be charged via the USB port, which can be very convenient when travelling.

Any camera decision will obviously take relative prices into account. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 Fujifilm X20 features a 2/3 sensor and the Sony RX100 IV an one-inch sensor. The sensor area in the RX100 IV 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 IV offers a 3:2 aspect.
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 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.
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 Fujifilm X20 has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Sony Cyber-shot DSC-RX100 IV are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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, but the RX100 IV provides a better video resolution than the X20. It can shoot movie footage at 4K/30p, while the Fujifilm is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the RX100 IV has an electronic viewfinder (2359k 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 Sony RX100 IV in connection with corresponding information for a sample of similar cameras.

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 X20 and the RX100 IV have zoom lenses built in. The X20 has a 28-112mm f/2.0-2.8 optic and the RX100 IV offers a 24-70mm f/1.8-2.8 (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 X20 writes its imaging data to SDXC cards, while the RX100 IV uses SDXC or Memory Stick PRO Duo 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.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Fujifilm X20 and Sony Cyber-shot DSC-RX100 IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X20 has a hotshoe, while the RX100 IV does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the X20 and the RX100 IV have been discontinued, but can regularly be found used on eBay. The X20 was replaced by the Fujifilm X30, while the RX100 IV was followed by the Sony RX100 IV. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Fujifilm and Sony websites.

If the number of relative strengths (bullet points above) is taken as a guide, the RX100 IV is the clear winner of the contest (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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Fujifilm X20 and the Sony RX100 IV 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 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 X20 or the RX100 IV perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
