Panasonic GX80 versus Panasonic GM5
The Panasonic Lumix DMC-GX80 (called Panasonic GX85 in some regions) and the Panasonic Lumix DMC-GM5 are two digital cameras that were announced, respectively, in April 2016 and September 2014. Both the GX80 and the GM5 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 GM5. Three consecutive perspectives from the front, the top, and the back are presented. All size dimensions 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 GX80 – represents 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 GM5 is considerably smaller (31 percent) than the Panasonic GX80. Moreover, the GM5 is substantially lighter (50 percent) than the GX80. In this context, it is worth noting that neither the GX80 nor the GM5 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 GM5 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. 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. 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.
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 GM5 have the same pixel density, as well as the same pixel size. It should, however, be noted that the GX80 is a somewhat more recent model (by 1 year and 6 months) than the GM5, and its sensor might 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 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. Of the two cameras under review, the GX80 has a notably higher overall DXO score than the GM5 (overall score 5 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.8 bits higher color depth, 0.9 EV in additional dynamic range, 0.1 stops of reduced 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 are not only capable of taking still images, but can also record movies. 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 GM5. It can shoot video footage at 4K/30p, while the GM5 is limited to 1080/60p.
Apart from 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 GX80 offers a substantially higher resolution than the one in the GM5 (2765k vs 1166k dots). The following table reports on some other key feature differences and similarities of the Panasonic GX80, the Panasonic GM5, and comparable cameras.

The GX80 is a current model that online retailers, such as amazon, will have in stock. In contrast, the GM5 has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the GM5 was succeeded by the ...
So how do things add up? Which of the two cameras – the Panasonic GX80 or the Panasonic GM5 – has the upper hand? The listing below highlights the relative strengths of the two models.
Arguments in favor 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 1080/60p).
- More detailed viewfinder: Has higher resolution electronic viewfinder (2765k vs 1166k dots).
- More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
- 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 5.8 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (290 versus 220) on a single battery charge.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- Sharper images: Has hand-shake reducing image stabilization build-in.

Advantages of the Panasonic Lumix DMC-GM5:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More compact: Is smaller (99x60mm vs 122x71mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 215g or 50 percent) and is thus easier to take along.
- More heavily discounted: Has been on the market for longer (launched in September 2014).
If the count of relative strengths (bullet points above) is taken as a measure, the GX80 is the clear winner of the match-up (13 : 4 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs.
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 handling experience and imaging performance when actually working with the GX80 or the GM5. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major 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 assessments were made in relation to similar cameras of the same technological generation. 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.
