Sony RX10 IV versus Fujifilm X-E3

The Sony Cyber-shot DSC-RX10 IV and the Fujifilm X-E3 are two digital cameras that were revealed to the public in September 2017. The RX10 IV is a fixed lens compact, while the X-E3 is a mirrorless interchangeable lens camera. The cameras are based on an one-inch (RX10 IV) and an APS-C (X-E3) sensor. The Sony has a resolution of 20 megapixel, whereas the Fujifilm provides 24 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 RX10 IV vs Fujifilm X-E3

An illustration of the physical size and weight of the Sony RX10 IV and the Fujifilm X-E3 is provided 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. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the RX10 IV – represents the basis or 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 Fujifilm X-E3 is notably smaller (28 percent) than the Sony RX10 IV. It is worth mentioning in this context that the RX10 IV is splash and dust resistant, while the X-E3 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX10 IV has a lens build in, whereas the X-E3 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-E3 and their specifications in the Fujinon X Lens Catalog.

Concerning battery life, the RX10 IV gets 400 shots out of its NP-FW50 battery, while the X-E3 can take 350 images on a single charge of its NP-W126S power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The camera’s price is obviously a critical decision-making factor. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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: Sony RX10 IV vs Fujifilm X-E3

The size of the imaging sensor is a crucial determinant 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. 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 Sony RX10 IV features an one-inch sensor and the Fujifilm X-E3 an APS-C sensor. The sensor area in the X-E3 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.

Sony RX10 IV and Fujifilm X-E3 sensor measures

With 24MP, the X-E3 offers a higher resolution than the RX10 IV (20MP), but the X-E3 nevertheless has larger individual pixels (pixel pitch of 3.92μm versus 2.41μm for the RX10 IV) 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. Coming back to sensor resolution, it should be mentioned that the X-E3 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

RX10 IV versus X-E3 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").

ilogo

Arguments in favor of the Fujifilm X-E3:

  • More detail: Has more megapixels (24 vs 20MP), which boosts linear resolution by 10%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • 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.
  • More compact: Is smaller (121x74mm vs 133x94mm) and will fit more readily into a bag.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.

If the count of individual advantages (bullet points above) is taken as a guide, the RX10 IV is the clear winner of the match-up (12 : 7 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision.

RX10 IV 12:07 X-E3

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the RX10 IV or the X-E3. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is why expert reviews are important. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
