Sony RX100 IV versus Fujifilm X-A2
The Sony Cyber-shot DSC-RX100 IV and the Fujifilm X-A2 are two digital cameras that were announced, respectively, in June 2015 and January 2015. The RX100 IV is a fixed lens compact, while the X-A2 is a mirrorless interchangeable lens camera. The cameras are based on an one-inch (RX100 IV) and an APS-C (X-A2) sensor. The Sony has a resolution of 20 megapixel, whereas the Fujifilm provides 16 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: Sony RX100 IV vs Fujifilm X-A2
The side-by-side display below illustrates the physical size and weight of the Sony RX100 IV and the Fujifilm X-A2. 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 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 RX100 IV – 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 X-A2 is notably larger (33 percent) than the Sony RX100 IV. In this context, it is worth noting that neither the RX100 IV nor the X-A2 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX100 IV has a lens build in, whereas the X-A2 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the X-A2 and their specifications in the Fujinon X Lens Catalog.
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 camera comparisons there.

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. 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: Sony RX100 IV vs Fujifilm X-A2
The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixel-units 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 Sony RX100 IV features an one-inch sensor and the Fujifilm X-A2 an APS-C sensor. The sensor area in the X-A2 is 217 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a smaller sensor, the Sony RX100 IV offers a higher resolution of 20 megapixel, compared with 16 MP of the Fujifilm X-A2. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 4.80μm for the X-A2). However, it should be noted that the RX100 IV is a somewhat more recent model (by 4 months) than the X-A2, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.
For most 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 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 RX100 IV provides a higher video resolution than the X-A2. It can shoot video footage at 4K/30p, while the Fujifilm is limited to 1080/30p.
Feature comparison: Sony RX100 IV vs Fujifilm X-A2
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the RX100 IV has an electronic viewfinder (2359k dots), which can be very helpful when shooting in bright sunlight. In contrast, the X-A2 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Sony RX100 IV, the Fujifilm X-A2, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Review summary: Sony RX100 IV vs Fujifilm X-A2
So how do things add up? Is the Sony RX100 IV better than the Fujifilm X-A2 or vice versa? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Sony Cyber-shot DSC-RX100 IV:
- More detail: Offers more megapixels (20 vs 16MP) with a 12% higher linear resolution.
- Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
- Easier framing: Has an electronic viewfinder for image framing and settings control.
- More detailed LCD: Has a higher resolution rear screen (1228k vs 920k dots).
- Faster burst: Shoots at higher frequency (16 vs 5.6 flaps/sec) to capture the decisive moment.
- Ready to shoot: Has a lens build-in, whereas the X-A2 requires a separate lens.
- More compact: Is smaller (102x58mm vs 117x67mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a build-in lens (unlike the X-A2).
- Sharper images: Has hand-shake reducing image stabilization build-in.
- More modern: Is somewhat more recent (announced 4 months after the X-A2).
Arguments in favor of the Fujifilm X-A2:
- Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
- Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- Longer lasting: Gets more shots (410 versus 280) out of a single battery charge.
- More heavily discounted: Has been on the market for longer (launched in January 2015).
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 (10 : 5 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.
In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the RX100 IV or the X-A2 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 following table reports the overall rankings of the cameras as published by some of the major camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, 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 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.
