Panasonic G85 vs GX850
The Panasonic Lumix DMC-G85 (called Panasonic G80 in some regions) and the Panasonic Lumix DMC-GX850 (labelled Panasonic GX800 in some countries) are two digital cameras that were revealed to the public, respectively, in September 2016 and January 2017. Both the G85 and the GX850 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. Both cameras offer a resolution of 15.8 megapixels.
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-G85 and the Panasonic Lumix DMC-GX850? 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 side-by-side display below illustrates the physical size and weight of the Panasonic G85 and the Panasonic GX850. 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 dimensions are rounded to the nearest millimeter.
The GX850 can be obtained in three different colors (black, silver, red), while the G85 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 GX850 is considerably smaller (39 percent) than the Panasonic G85. Moreover, the GX850 is substantially lighter (47 percent) than the G85. It is worth mentioning in this context that the G85 is splash and dust resistant, 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. 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.
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 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 39 percent) than the G85, 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 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 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. 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 associated with larger, more expensive camera bodies 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.
The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 15.8 megapixels. This similarity in sensor specs implies that both the G85 and the GX850 have the same pixel density, as well as the same pixel size. It should, however, be noted that the GX850 is a somewhat more recent model (by 3 months) than the G85, and its sensor might have benefitted from technological advances during this time. 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 Panasonic Lumix DMC-G85 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The Panasonic Lumix DMC-GX850 offers exactly the same ISO settings.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 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 G85 has an electronic viewfinder (2360k 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 adjacent table lists some of the other core features of the Panasonic G85 and Panasonic GX850 along with similar information for a selection of comparators.

|4.||Olympus E-M5 II||2360||n||3.0||1037||swivel||Y||1/8000s||10.0||n||Y|
One feature that differentiates the G85 and the GX850 is in-body image stabilization (IBIS). The G85 reduces the risk of handshake-induced blur with all attached lenses, while the GX850 offers no blur reduction with lenses that themselves do not provide optical image stabilization.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
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 G85 and the Panasonic GX850 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 G85 and the GX850 write their files to SDXC cards. The G85 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the GX850 can use UHS-I cards (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-G85 and Panasonic Lumix DMC-GX850 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G85 has a hotshoe, while the GX850 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
The GX850 is a recent model that features in the current product line-up of Panasonic. In contrast, the G85 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the G85 was succeeded by the Panasonic G95. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic website.
So what is the bottom line? Is the Panasonic G85 better than the Panasonic GX850 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Panasonic Lumix DMC-G85:
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/500s) to freeze action.
- Longer lasting: Can take more shots (330 versus 210) on a single battery charge.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- Sharper images: Has hand-shake reducing image stabilization built-in.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
- More heavily discounted: Has been on the market for longer (launched in September 2016).
Advantages of the Panasonic Lumix DMC-GX850:
- More dynamic range: Captures a broader range of light and dark details (0.8 EV of extra DR).
- More compact: Is smaller (107x65mm vs 128x89mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 236g or 47 percent) and is thus easier to take along.
- More affordable: Was introduced into a lower priced category (39 percent cheaper at launch).
- More modern: Was introduced somewhat (3 months) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the G85 is the clear winner of the match-up (10 : 5 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. 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.
How about other alternatives? Do the specifications of the Panasonic G85 and the Panasonic GX850 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 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 G85 or the GX850 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 hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
