Panasonic GX80 versus Panasonic GM1
The Panasonic Lumix DMC-GX80 (called Panasonic GX85 in some regions) and the Panasonic Lumix DMC-GM1 are two digital cameras that were revealed to the public, respectively, in April 2016 and October 2013. Both the GX80 and the GM1 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. Both cameras offer a resolution of 15.8 megapixel.
The side-by-side display below illustrates the physical size and weight of the Panasonic GX80 and the Panasonic GM1. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter. You can also toggle the display 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 GX80 – 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 GM1 is considerably smaller (37 percent) than the Panasonic GX80. Moreover, the GM1 is substantially lighter (52 percent) than the GX80. In this context, it is worth noting that neither the GX80 nor the GM1 are weather-sealed.
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 GM1 was somewhat cheaper (by 6 percent) than the GX80 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 size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixel-units 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 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 GX80 and the GM1 have the same pixel density, as well as the same pixel size. It should, however, be noted that the GX80 is much more recent (by 2 years and 5 months) than the GM1, and its sensor will have benefitted from technological advances during this time. Coming back to sensor resolution, it should be mentioned that the GX80 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"). Of the two cameras under review, the GX80 has a notably higher overall DXO score than the GM1 (overall score 5 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.6 bits higher color depth, 0.9 EV in additional dynamic range, and 0 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

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 GX80 provides a higher video resolution than the GM1. It can shoot video footage at 4K/30p, while the GM1 is limited to 1080/60i.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the GX80 has an electronic viewfinder (2765k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GM1 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Panasonic GX80 and Panasonic GM1 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 GX80 is a current model that online retailers, such as amazon, will have in stock. In contrast, the GM1 has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the GM1 was succeeded by the Panasonic GM5.
So what is the bottom line? Is the Panasonic GX80 better than the Panasonic GM1 or vice versa? The listing below highlights the relative strengths of the two models.
Advantages of the Panasonic Lumix DMC-GX80:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores markedly higher (5 points) in the DXO overall assessment.
- More dynamic range: Captures a larger spectrum of light and dark details (0.9 EV of extra DR).
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60i).
- Easier framing: Has an electronic viewfinder for image framing and settings control.
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Faster shutter: Has higher mechanical shutter speed (4000/sec vs 500/sec) to freeze action.
- Faster burst: Shoots at higher frequency (8 vs 5 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (290 versus 230) on a single battery charge.
- Sharper images: Has hand-shake reducing image stabilization build-in.
- More modern: Reflects 2 years and 5 months of technical progress since the GM1 launch.
Arguments in favor of the Panasonic Lumix DMC-GM1:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More compact: Is smaller (99x55mm vs 122x71mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 222g or 52 percent) and is thus easier to take along.
- More heavily discounted: Has been around for much longer (launched in October 2013).
If the count of relative strengths (bullet points above) is taken as a measure, the GX80 is the clear winner of the match-up (11 : 4 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.
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 GX80 and the GM1 in practical situations. 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price 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.
