Fujifilm X-A3 versus Sony RX100 V

The Fujifilm X-A3 and the Sony Cyber-shot DSC-RX100 V are two digital cameras that were announced, respectively, in August 2016 and October 2016. The X-A3 is a mirrorless interchangeable lens camera, while the RX100 V is a fixed lens compact. The cameras are based on an APS-C (X-A3) and an one-inch (RX100 V) sensor. The Fujifilm has a resolution of 24 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 X-A3 vs Sony RX100 V

An illustration of the physical size and weight of the Fujifilm X-A3 and the Sony RX100 V is provided 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 dimensions are rounded to the nearest millimeter. You can also toggle the display 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 – the X-A3 – 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 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 build 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 find an overview of optics 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 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: Fujifilm X-A3 vs Sony RX100 V

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. 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 are more costly to manufacture and tend to 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.

Fujifilm X-A3 and Sony RX100 V sensor measures

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.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, 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: Fujifilm X-A3 vs Sony RX100 V

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 following table reports on some other key feature differences and similarities of the Fujifilm X-A3, the Sony RX100 V, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the X-A3 and the RX100 V are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The X-A3 replaced the earlier Fujifilm X-A2, while the RX100 V followed on from the Sony RX100 IV.

Review summary: Fujifilm X-A3 vs Sony RX100 V

So what conclusions can be drawn? Which of the two cameras – the Fujifilm X-A3 or the Sony RX100 V – has the upper hand? The listing below highlights the relative strengths of the two models.

ilogo

Reasons to prefer the Fujifilm X-A3:

  • More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
  • Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • 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.

ilogo

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 framing 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 build in (unlike the X-A3).
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.

If the count of individual advantages (bullet points above) is taken as a guide, the RX100 V emerges as the winner of the match-up (8 : 6 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.

X-A3 06:08 RX100 V

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the X-A3 and the RX100 V 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. This is where reviews by experts come in. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
