Panasonic GH5s vs GX85
The Panasonic Lumix DC-GH5s and the Panasonic Lumix DMC-GX85 (labelled Panasonic GX80 in some countries) are two digital cameras that were announced, respectively, in January 2018 and April 2016. Both the GH5s and the GX85 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The GH5s has a resolution of 9.9 megapixels, whereas the GX85 provides 15.8 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 DC-GH5s and the Panasonic Lumix DMC-GX85? 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 GH5s and the Panasonic GX85 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 width, height and depth measures are rounded to the nearest millimeter.
The GX85 can be obtained in two different colors (black, silver), while the GH5s 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 Panasonic GX85 is considerably smaller (36 percent) than the Panasonic GH5s. Moreover, the GX85 is substantially lighter (35 percent) than the GH5s. It is worth mentioning in this context that the GH5s is splash and dust resistant, while the GX85 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Micro Four Thirds Lens Catalog. 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 GH5s gets 440 shots out of its DMW-BLF19 battery, while the GX85 can take 290 images on a single charge of its DMW-BLG10 power pack. The power pack in the GX85 can be charged via the USB port, which can be very convenient when travelling.
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, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision 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 GX85 was launched at a markedly lower price (by 68 percent) than the GH5s, 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 imaging sensor is a crucial determinant 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. 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.
Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
While the two cameras under review share the same sensor size, the GX85 offers a higher resolution of 15.8 megapixels, compared with 9.9 MP of the GH5s. This megapixels advantage translates into a 25 percent gain in linear resolution. On the other hand, these sensor specs imply that the GX85 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.77μm versus 4.77μm for the GH5s). Moreover, it should be noted, that the GH5s is a somewhat more recent model (by 1 year and 9 months) than the GX85, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels. 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.
The resolution advantage of the Panasonic GX85 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GX85 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 Panasonic GH5s are 18.4 x 13.5 inches or 46.7 x 34.3 cm for good quality, 14.7 x 10.8 inches or 37.4 x 27.4 cm for very good quality, and 12.3 x 9 inches or 31.2 x 22.9 cm for excellent quality prints.
The Panasonic Lumix DC-GH5s has a native sensitivity range from ISO 160 to ISO 51200, which can be extended to ISO 80-204800. The corresponding ISO settings for the Panasonic Lumix DMC-GX85 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
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"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the GH5s provides a higher frame rate than the GX85. It can shoot video footage at 4K/60p, while the GX85 is limited to 4K/30p.
Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the GH5s offers a substantially higher resolution than the one in the GX85 (3680k vs 2765k dots). The following table reports on some other key feature differences and similarities of the Panasonic GH5s, the Panasonic GX85, and comparable cameras.

One feature that differentiates the GX85 and the GH5s is in-body image stabilization (IBIS). The GX85 reduces the risk of handshake-induced blur with all attached lenses, while the GH5s offers no blur reduction with lenses that themselves do not provide optical image stabilization.The GH5s 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 GX85 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 GH5s and the Panasonic GX85 both have 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.
Concerning the storage of imaging data, both the GH5s and the GX85 write their files to SDXC cards. The GH5s features dual card slots, which can be very useful in case a memory card fails. In contrast, the GX85 only has one slot. The GH5s supports UHS-II cards (on both slots), while the GX85 can use UHS-I cards.
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 DC-GH5s and Panasonic Lumix DMC-GX85 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GH5s has a microphone port, which is missing on the GX85. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Studio photographers will appreciate that the Panasonic GH5s (unlike the GX85) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the GH5s and the GX85 are recent models that are part of the current product line-up. The GX85 replaced the earlier Panasonic GX7, while the GH5s does not have a direct predecessor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic website.

If the count of relative strengths (bullet points above) is taken as a measure, the GH5s is the clear winner of the match-up (20 : 8 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the GH5s or the GX85. 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 where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], 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.

The above review scores should be interpreted with care, 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.
