Panasonic GX850 vs Sony A7S II
The Panasonic Lumix DMC-GX850 (called Panasonic GX800 in some regions) and the Sony Alpha 7S II are two digital cameras that were officially introduced, respectively, in January 2017 and September 2015. Both the GX850 and the A7S II are mirrorless interchangeable lens cameras that are based on a Four Thirds (GX850) and a full frame (A7S II) sensor. The Panasonic has a resolution of 15.8 megapixels, whereas the Sony provides 12 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GX850 and the Sony Alpha 7S II? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
The physical size and weight of the Panasonic GX850 and the Sony A7S II are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.
The GX850 can be obtained in three different colors (black, silver, red), while the A7S II is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7S II is considerably larger (75 percent) than the Panasonic GX850. Moreover, the A7S II is substantially heavier (133 percent) than the GX850. It is noteworthy in this context that the A7S II is splash and dust-proof, while the GX850 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 compare the optics available for the two cameras in the Micro Four Thirds Lens Catalog (GX850) and the Sony FE Lens Catalog (A7S II). 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 GX850 gets 210 shots out of its DMW-BLH7 battery, while the A7S II can take 370 images on a single charge of its NP-FW50 power pack. The power pack in the A7S II can be charged via the USB port, which can be very convenient when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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 GX850 was launched at a markedly lower price (by 82 percent) than the A7S II, 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.
The size of the imaging sensor is a crucial determinant 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Panasonic GX850 features a Four Thirds sensor and the Sony A7S II a full frame sensor. The sensor area in the A7S II is 276 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the GX850 has a native 4:3 aspect ratio, while the one in the A7S II offers a 3:2 aspect.
Despite having a smaller sensor, the Panasonic GX850 offers a higher resolution of 15.8 megapixels, compared with 12 MP of the Sony A7S II. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.77μm versus 8.40μm for the A7S II). However, it should be noted that the GX850 is a somewhat more recent model (by 1 year and 3 months) than the A7S II, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage. Coming back to sensor resolution, it should be mentioned that the GX850 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Panasonic GX850 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GX850 for good quality output (200 dots per inch) amounts to 23 x 17.2 inches or 58.3 x 43.8 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.7 x 35 cm, and for excellent quality (300 dpi) 15.3 x 11.5 inches or 38.9 x 29.2 cm. The corresponding values for the Sony A7S II are 21.2 x 14.2 inches or 53.8 x 36 cm for good quality, 17 x 11.3 inches or 43.1 x 28.8 cm for very good quality, and 14.1 x 9.4 inches or 35.9 x 24 cm for excellent quality prints.
The Panasonic Lumix DMC-GX850 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the Sony Alpha 7S II are ISO 100 to ISO 102400, with the possibility to increase the ISO range to 50-409600.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
For many cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under consideration, the A7S II offers substantially better image quality than the GX850 (overall score 12 points higher). The advantage is based on 0.4 bits higher color depth, and 2.4 stops in additional low light sensitivity. 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (4K/30p).
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A7S II has an electronic viewfinder (2400k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GX850 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Panasonic GX850 and Sony A7S II in connection with corresponding information for a sample of similar cameras.

|Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.|
One difference between the cameras concerns the presence of an on-board flash. The GX850 has one, while the A7S II does not. While the built-in flash of the GX850 is not very powerful, it can at times be useful as a fill-in light.The GX850 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the A7S II does not have a selfie-screen.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, both cameras under consideration feature an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Panasonic GX850 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The GX850 writes its imaging data to SDXC cards, while the A7S II uses SDXC or Memory Stick PRO Duo cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Panasonic Lumix DMC-GX850 and Sony Alpha 7S II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7S II has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The GX850 lacks such a headphone port.
The GX850 is a recent model that features in the current product line-up of Panasonic. In contrast, the A7S II has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the A7S II was succeeded by the Sony A7S III. Further information on the features and operation of the GX850 and A7S II can be found, respectively, in the Panasonic GX850 Manual (free pdf) or the online Sony A7S II Manual.
So how do things add up? Is the Panasonic GX850 better than the Sony A7S II or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Panasonic Lumix DMC-GX850:
- More detail: Offers more megapixels (15.8 vs 12MP) with a 13% higher linear resolution.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.

- More heavily discounted: Has been on the market for longer (launched in September 2015).
If the number of relative strengths (bullet points above) is taken as a guide, the A7S II is the clear winner of the contest (15 : 11 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Panasonic GX850 and the Sony A7S II place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.
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 shooting experience and imaging performance when actually working with the GX850 or the A7S II. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
