Sony RX10 IV versus Fujifilm X-Pro2

The Sony Cyber-shot DSC-RX10 IV and the Fujifilm X-Pro2 are two enthusiast cameras that were revealed to the public, respectively, in September 2017 and January 2016. The RX10 IV is a fixed lens compact, while the X-Pro2 is a mirrorless interchangeable lens camera. The cameras are based on an one-inch (RX10 IV) and an APS-C (X-Pro2) 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-Pro2

The physical size and weight of the Sony RX10 IV and the Fujifilm X-Pro2 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures 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 side – the RX10 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-Pro2 is notably smaller (6 percent) than the Sony RX10 IV. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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-Pro2 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-Pro2 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-Pro2 can take 350 images on a single charge of its NP-W126 power pack.

Any camera purchase will naturally be influenced heavily by the price. 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. 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 RX10 IV vs Fujifilm X-Pro2

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-Pro2 an APS-C sensor. The sensor area in the X-Pro2 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-Pro2 sensor measures

With 24MP, the X-Pro2 offers a higher resolution than the RX10 IV (20MP), but the X-Pro2 nevertheless has larger individual pixels (pixel pitch of 3.92μm versus 2.41μm for the RX10 IV) due to its larger sensor. However, the RX10 IV is a somewhat more recent model (by 1 year and 7 months) than the X-Pro2, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the X-Pro2 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

RX10 IV versus X-Pro2 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"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The RX10 IV has one, while the X-Pro2 does not. While the build-in flash of the RX10 IV is not very powerful, it can at times be useful as a fill-in light.

The RX10 IV writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the X-Pro2 uses SDXC cards. The X-Pro2 features dual card slots, which can be very useful in case a memory card fails. In contrast, the RX10 IV only has one slot.

  • Better low-light sensitivity: Can be used in poorly lit environments and still produce good images.
  • More detailed LCD: Has a higher resolution rear screen (1620k vs 1440k dots).
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 2000/sec) to freeze action.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been on the market for longer (launched in January 2016).

If the count of relative strengths (bullet points above) is taken as a measure, the RX10 IV emerges as the winner of the contest (13 : 11 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.

RX10 IV 13:11 X-Pro2

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the RX10 IV and the X-Pro2 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 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 (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
