Sony RX10 IV versus Fujifilm X-A10

The Sony Cyber-shot DSC-RX10 IV and the Fujifilm X-A10 are two digital cameras that were officially introduced, respectively, in September 2017 and December 2016. The RX10 IV is a fixed lens compact, while the X-A10 is a mirrorless interchangeable lens camera. The cameras are based on an one-inch (RX10 IV) and an APS-C (X-A10) 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 RX10 IV vs Fujifilm X-A10

The side-by-side display below illustrates the physical size and weight of the Sony RX10 IV and the Fujifilm X-A10. 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 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 – 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-A10 is considerably smaller (37 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-A10 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-A10 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-A10 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-A10 can take 410 images on a single charge of its NP-W126S power pack.

The camera’s price is obviously a critical decision-making factor. 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. 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-A10

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 RX10 IV features an one-inch sensor and the Fujifilm X-A10 an APS-C sensor. The sensor area in the X-A10 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-A10 sensor measures

Despite having a smaller sensor, the Sony RX10 IV offers a higher resolution of 20 megapixel, compared with 16 MP of the Fujifilm X-A10. 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-A10). However, it should be noted that the RX10 IV is a somewhat more recent model (by 9 months) than the X-A10, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the RX10 IV provides a higher video resolution than the X-A10. It can shoot video footage at 4K/30p, while the Fujifilm is limited to 1080/30p.

 

Feature comparison: Sony RX10 IV vs Fujifilm X-A10

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the RX10 IV has an electronic viewfinder (2359k dots), which can be very helpful when shooting in bright sunlight. In contrast, the X-A10 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 RX10 IV, the Fujifilm X-A10, and comparable cameras.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the X-A10 features an electronic shutter, which makes silent shooting and higher burst speeds possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the RX10 IV and the X-A10 are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The X-A10 replaced the earlier Fujifilm X-A3, while the RX10 IV followed on from the Sony RX10 III.

If the count of relative strengths (bullet points above) is taken as a measure, the RX10 IV is the clear winner of the match-up (11 : 6 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 11:06 X-A10

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 RX10 IV and the X-A10 in practical situations. 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 where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular 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. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
