Fujifilm X-A3 versus Fujifilm GFX 50S

The Fujifilm X-A3 and the Fujifilm GFX 50S are two digital cameras that were announced, respectively, in August 2016 and September 2016. Both the X-A3 and the GFX 50S are mirrorless interchangeable lens cameras that are based on an APS-C (X-A3) and a medium format (GFX 50S) sensor. The X-A3 has a resolution of 24 megapixel, whereas the GFX 50S provides 51.1 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 Fujifilm GFX 50S

The physical size and weight of the Fujifilm X-A3 and the Fujifilm GFX 50S are illustrated 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 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 side – the X-A3 – 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 GFX 50S is considerably larger (77 percent) than the Fujifilm X-A3. Moreover, the GFX 50S is substantially heavier (118 percent) than the X-A3. It is noteworthy in this context that the GFX 50S is splash and dust-proof, while the X-A3 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. Hence, you might want to study the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the X-A3 gets 410 shots out of its NP-W126S battery, while the GFX 50S can take 400 images on a single charge of its NP-T125 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

The price is, of course, an important factor in any camera decision. 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-A3 was launched at a markedly lower price (by 94 percent) than the GFX 50S, which puts it into a different market segment. 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: Fujifilm X-A3 vs Fujifilm GFX 50S

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 more expensive and 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 Fujifilm GFX 50S a medium format sensor. The sensor area in the GFX 50S is 293 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 0.79. The sensor in the X-A3 has a native 3:2 aspect ratio, while the one in the GFX 50S offers a 4:3 aspect.

In terms of underlying technology, both cameras are build around CMOS sensors.

Fujifilm X-A3 and Fujifilm GFX 50S sensor measures

With 51.1MP, the GFX 50S offers a higher resolution than the X-A3 (24MP), but the GFX 50S nevertheless has larger individual pixels (pixel pitch of 5.33μm versus 3.92μm for the X-A3) 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 GFX 50S has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

X-A3 versus GFX 50S MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the X-A3 provides a higher frame rate than the GFX 50S. It can shoot video footage at 1080/60p, while the GFX 50S is limited to 1080/30p.

 

Feature comparison: Fujifilm X-A3 vs Fujifilm GFX 50S

Beyond body and sensor, cameras can and do differ across a range of features. The X-A3 and the GFX 50S are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. That said, the GFX 50S can be equipped with an optional viewfinder – the EVF-TL1. The table below summarizes some of the other core capabilities of the Fujifilm X-A3 and Fujifilm GFX 50S in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

One difference between the cameras concerns the presence of an on-board flash. The X-A3 has one, while the GFX 50S does not. While the build-in flash of the X-A3 is not very powerful, it can at times be useful as a fill-in light.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the GFX 50S features 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).

Both the X-A3 and the GFX 50S write their imaging data to SDXC cards. The GFX 50S features dual card slots, which can be very useful in case a memory card fails. In contrast, the X-A3 only has one slot.

  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (2360k vs 1040k dots).
  • More flexible LCD: Has full-flex screen for odd-angle shots in portrait or landscape orientation.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.

If the count of individual advantages (bullet points above) is taken as a guide, the GFX 50S is the clear winner of the contest (13 : 7 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.

X-A3 07:13 GFX 50S

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the X-A3 or the GFX 50S. 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 hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
