Panasonic GX7 versus Panasonic G85
The Panasonic Lumix DMC-GX7 and the Panasonic Lumix DMC-G85 (called Panasonic G80 in some regions) are two digital cameras that were revealed to the public, respectively, in August 2013 and September 2016. Both the GX7 and the G85 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. Both cameras offer a resolution of 15.8 megapixel.
An illustration of the physical size and weight of the Panasonic GX7 and the Panasonic G85 is provided in the side-by-side display below. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the GX7 – 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 Panasonic G85 is notably larger (30 percent) than the Panasonic GX7. Moreover, the G85 is markedly heavier (26 percent) than the GX7. Cameras intended for semi-professional or professional use tend to be a bit bulkier in order to give them the necessary ruggedness. It is noteworthy in this context that the G85 is splash and dust-proof, while the GX7 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 find an overview of suitable optics 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 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 G85 was somewhat cheaper (by 10 percent) than the GX7 at launch, but both cameras fall into the same price category. 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 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. 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.
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 megapixel. This similarity in sensor specs implies that both the GX7 and the G85 have the same pixel density, as well as the same pixel size. It should, however, be noted that the G85 is much more recent (by 3 years and 1 month) than the GX7, and its sensor will have benefitted from technological advances during this time. Coming back sensor resolution, it should be mentioned that the G85 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the G85 provides a better video resolution than the GX7. It can shoot movie footage at 4K/30p, while the GX7 is limited to 1080/60p.
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 GX7 offers a higher resolution than the one in the G85 (2760k vs 2360k dots). The adjacent table lists some of the other core features of the Panasonic GX7 and Panasonic G85 along with similar information for a selection of comparators. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The G85 is a current model that online retailers, such as amazon, will have in stock. In contrast, the GX7 has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the GX7 was succeeded by the Panasonic GX85.
So what conclusions can be drawn? Is there a clear favorite between the Panasonic GX7 and the Panasonic GX7? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Panasonic Lumix DMC-GX7:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More detailed viewfinder: Has a higher resolution electronic viewfinder (2760k vs 2360k dots).
- Faster shutter: Has a higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
- More compact: Is smaller (123x71mm vs 128x89mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 103g or 20 percent) and hence easier to carry around.
- More heavily discounted: Has been available for much longer (launched in August 2013).
Advantages of the Panasonic Lumix DMC-G85:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Faster burst: Shoots at higher frequency (9 vs 5 flaps/sec) to capture the decisive moment.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- More modern: Reflects 3 years and 1 month of technical progress since the GX7 launch.
If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (6 points each). 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.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the GX7 and the G85 in practical situations. 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 where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites. You can find the full text of the reviews, 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 were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
