Sony A99 II versus Fujifilm GFX 50S

The Sony Alpha ALT-A99 II and the Fujifilm GFX 50S are two professional cameras that were officially introduced in September 2016. The A99 II is a DSLR, while the GFX is a mirrorless interchangeable lens camera. The cameras are based on a full frame (A99 II) and a medium format (GFX) sensor. The Sony has a resolution of 42.2 megapixel, whereas the Fujifilm 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: Sony A99 II vs Fujifilm GFX 50S

The side-by-side display below illustrates the physical size and weight of the Sony A99 II and the Fujifilm GFX 50S. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures 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 side – the A99 II – 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 notably smaller (6 percent) than the Sony A99 II. Moreover, the GFX is markedly lighter (13 percent) than the A99 II. 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.

Concerning battery life, the A99 II gets 490 shots out of its NP-FM500H battery, while the GFX can take 400 images on a single charge of its NP-T125 power pack.

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 camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The A99 II 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.


Sensor comparison: Sony A99 II 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. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Sony A99 II 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 A99 II has a native 3:2 aspect ratio, while the one in the GFX offers a 4:3 aspect.

Sensor size

With 51.1MP, the GFX offers a higher resolution than the A99 II (42.2MP), but the GFX nevertheless has larger individual pixels (pixel pitch of 5.33μm versus 4.52μm for the A99 II) 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the A99 II provides a higher video resolution than the GFX. It can shoot video footage at 4K/30p, while the Fujifilm is limited to 1080/30p.

Feature comparison: Sony A99 II vs Fujifilm GFX 50S

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A99 II has an electronic viewfinder (2400k 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 following table reports on some other key feature differences and similarities of the Sony A99 II, the Fujifilm GFX 50S, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the A99 II or the GFX handle or perform in practice. 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. The table below summarizes the assessments of some of the best known camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
