Sony A7R III versus Fujifilm GFX 50S
The Sony Alpha A7R III and the Fujifilm GFX 50S are two digital cameras that were revealed to the public, respectively, in October 2017 and September 2016. Both the A7R III and the GFX are mirrorless interchangeable lens cameras that are based on a full frame (A7R III) and a medium format sensor. The Sony has a resolution of 42.2 megapixel, whereas the Fujifilm provides 51.1 MP.
The side-by-side display below illustrates the physical size and weight of the Sony A7R III and the Fujifilm GFX 50S. Three consecutive perspectives from the front, the top, and the back are presented. 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 A7R III – 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 GFX 50S is notably larger (14 percent) than the Sony A7R III. Moreover, the GFX is markedly heavier (14 percent) than the A7R III. 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 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.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The A7R III was launched at a markedly lower price (by 51 percent) than the GFX, 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.
The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color depth than smaller pixels 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 are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Sony A7R III features a full frame sensor and the Fujifilm GFX 50S a medium format sensor. The sensor area in the GFX is 68 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 0.79. The sensor in the A7R III has a native 3:2 aspect ratio, while the one in the GFX offers a 4:3 aspect.
With 51.1MP, the GFX offers a higher resolution than the A7R III (42.2MP), but the GFX nevertheless has larger individual pixels (pixel pitch of 5.33μm versus 4.52μm for the A7R III) due to its larger sensor. However, the A7R III is a somewhat more recent model (by 1 year and 1 month) than the GFX, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.
Unlike the GFX, the A7R III has the capacity to capture high quality composite images by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
Consistent information on actual sensor performance is available from DXO Mark for most cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the A7R III provides a higher video resolution than the GFX. It can shoot video footage at 4K/30p, while the Fujifilm is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the A7R III has an electronic viewfinder (3686k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GFX relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Sony A7R III 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.

Both the A7R III and the GFX are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The A7R III replaced the earlier Sony A7R II, while the GFX does not have a direct predecessor.
So what is the bottom line? Is the Sony A7R III better than the Fujifilm GFX 50S or vice versa? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Sony Alpha A7R III:
- High quality composites: Can combine several shots after pixel-shifting its sensor.
- Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
- Easier framing: Has an electronic viewfinder for image framing and settings control.
- Faster shutter: Has a higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
- Faster burst: Shoots at higher frequency (10 vs 3 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (127x96mm vs 148x94mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 90g or 12 percent) and hence easier to carry around.
- Longer lasting: Can take more shots (650 versus 400) on a single battery charge.
- Sharper images: Has hand-shake reducing image stabilization build-in.
- More affordable: Was introduced into a lower priced category (51 percent cheaper at launch).
- More modern: Is somewhat more recent (announced 1 year and 1 month after the GFX).
Arguments in favor of the Fujifilm GFX 50S:
- More detail: Has more megapixels (51.1 vs 42.2MP), which boosts linear resolution by 8%.
- Easier setting verification: Has 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 1440k dots).
- More heavily discounted: Has been on the market for longer (launched in October 2017).
If the number of relative strengths (bullet points above) is taken as a guide, the A7R III is the clear winner of the match-up (11 : 5 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.
In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the A7R III or the GFX handle or perform in practice. 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 table below summarizes the assessments of some of the best known camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted with care, though. The ratings are only valid when refering 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
