Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X-A3 and the Sony Cyber-shot DSC-RX100 V? 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.

Body comparison

The physical size and weight of the Fujifilm X-A3 and the Sony RX100 V are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

The X-A3 can be obtained in three different colors (silver, brown, pink), while the RX100 V 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 V is notably smaller (25 percent) than the Fujifilm X-A3. In this context, it is worth noting that neither the X-A3 nor the RX100 V are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX100 V has a lens built in, whereas the X-A3 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the X-A3 and their specifications in the Fujinon X Lens Catalog.

Concerning battery life, the X-A3 gets 410 shots out of its NP-W126S battery, while the RX100 V can take 220 images on a single charge of its NP-BX1 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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 Fujifilm X-A3 features an APS-C sensor and the Sony RX100 V an one-inch sensor. The sensor area in the RX100 V is 69 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 24MP, the X-A3 offers a higher resolution than the RX100 V (20MP), but the X-A3 nevertheless has larger individual pixels (pixel pitch of 3.92μm versus 2.41μm for the RX100 V) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.

The resolution advantage of the Fujifilm X-A3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-A3 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Sony RX100 V are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.

The Fujifilm X-A3 has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-25600. The corresponding ISO settings for the Sony Cyber-shot DSC-RX100 V are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.

In terms of underlying technology, the X-A3 is build around a CMOS sensor, while the RX100 V uses a BSI-CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Note: DXO values in italics represent estimates based on sensor size and age.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the RX100 V provides a better video resolution than the X-A3. It can shoot movie footage at 4K/30p, while the Fujifilm is limited to 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the RX100 V has an electronic viewfinder (2359k dots), which can be very helpful when shooting in bright sunlight. In contrast, the X-A3 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Fujifilm X-A3 and Sony RX100 V along with similar information for a selection of comparators.

Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The X-A3 has a touchscreen, while the RX100 V has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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, both cameras under consideration feature an 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).

The Fujifilm X-A3 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The X-A3 writes its imaging data to SDXC cards, while the RX100 V uses SDXC or Memory Stick PRO Duo cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

Connectivity comparison

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 X-A3 and Sony Cyber-shot DSC-RX100 V and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X-A3 has a hotshoe, while the RX100 V does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the X-A3 and the RX100 V have been discontinued, but can regularly be found used on ebay. The X-A3 was replaced by the Fujifilm X-A5, while the RX100 V was followed by the Sony RX100 VI. Further information on the features and operation of the X-A3 and RX100 V can be found, respectively, in the Fujifilm X-A3 Manual (free pdf) or the online Sony RX100 V Manual.

Review summary

So what is the bottom line? Is the Fujifilm X-A3 better than the Sony RX100 V or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Fujifilm X-A3:

• More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• Longer lasting: Can take more shots (410 versus 220) on a single battery charge.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.

Arguments in favor of the Sony Cyber-shot DSC-RX100 V:

• Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
• Faster burst: Shoots at higher frequency (24 vs 6 flaps/sec) to capture the decisive moment.
• Ready to shoot: Has an integrated lens, whereas the X-A3 necessitates an extra lens.
• More compact: Is smaller (102x58mm vs 117x67mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the X-A3).
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.

If the count of individual advantages (bullet points above) is taken as a guide, the X-A3 emerges as the winner of the contest (11 : 9 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 X-A3 and the Sony RX100 V place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Travel-Zoom Camera listings 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 X-A3 and the RX100 V 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.

Expert reviews

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
