Sony A7 III versus Fujifilm X-A10

The Sony Alpha A7 III and the Fujifilm X-A10 are two digital cameras that were officially introduced, respectively, in February 2018 and December 2016. Both the A7 III and the X-A10 are mirrorless interchangeable lens cameras that are based on a full frame (A7 III) and an APS-C (X-A10) sensor. The Sony has a resolution of 24 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 A7 III vs Fujifilm X-A10

The side-by-side display below illustrates the physical size and weight of the Sony A7 III and the Fujifilm X-A10. 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 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 A7 III – 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 Fujifilm X-A10 is considerably smaller (36 percent) than the Sony A7 III. Moreover, the X-A10 is substantially lighter (49 percent) than the A7 III. It is worth mentioning in this context that the A7 III 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 since they do not consider the interchangeable lenses that both of these cameras require. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can find an overview of optics for the two cameras in the Sony FE Lens Catalog (A7 III) and the Fujinon X Lens Catalog (X-A10). Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.

Concerning battery life, the A7 III gets 610 shots out of its NP-FZ100 battery, while the X-A10 can take 410 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. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera.

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. The X-A10 was launched at a markedly lower price (by 80 percent) than the A7 III, which puts it into a different market segment. 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 A7 III vs Fujifilm X-A10

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. 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 Sony A7 III features a full frame sensor and the Fujifilm X-A10 an APS-C sensor. The sensor area in the X-A10 is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sony A7 III and Fujifilm X-A10 sensor measures

With 24MP, the A7 III offers a higher resolution than the X-A10 (16MP), but the A7 III nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 4.80μm for the X-A10) due to its larger sensor. Moreover, the A7 III is a somewhat more recent model (by 1 year and 2 months) than the X-A10, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the A7 III has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The A7 III has on-sensor phase detect pixels, which results in relatively fast and reliable autofocus acquisition during video recording.

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 A7 III 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 A7 III vs Fujifilm X-A10

Apart from body and sensor, cameras can and do differ across a range of features. For example, the A7 III 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 A7 III, the Fujifilm X-A10, and comparable cameras. The full specs-sheets can be found in the camera manual or in the dpreview camera hub.

One feature that differentiates the A7 III and the X-A10 is in-body image stabilization (IBIS). The A7 III reduces the risk of handshake-induced blur with all attached lenses, while the X-A10 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

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

The A7 III writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the X-A10 uses SDXC cards.

A7 III 22:07 X-A10

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the A7 III or the X-A10. 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
