Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GM5 and the Panasonic Lumix DC-GX9? 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.
An illustration of the physical size and weight of the Panasonic GM5 and the Panasonic GX9 is provided 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 size dimensions are rounded to the nearest millimeter.
Both cameras are available in two different colors (black, silver).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GX9 is considerably larger (50 percent) than the Panasonic GM5. Moreover, the GX9 is substantially heavier (93 percent) than the GM5. In this context, it is worth noting that neither the GM5 nor the GX9 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 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 GM5 gets 220 shots out of its DMW-BLH7 battery, while the GX9 can take 260 images on a single charge of its DMW-BLG10 power pack. The power pack in the GX9 can be charged via the USB port, which can be very convenient when travelling.

Any camera decision will obviously take relative prices into account. 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 GM5 was launched at a somewhat lower price (by 12 percent) than the GX9, which makes it more attractive for photographers on a tight budget. 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 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. 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 are more costly to manufacture and tend 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.
While the two cameras under review share the same sensor size, the GX9 offers a higher resolution of 20.2 megapixels, compared with 15.8 MP of the GM5. This megapixels advantage translates into a 13 percent gain in linear resolution. On the other hand, these sensor specs imply that the GX9 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 3.77μm for the GM5). However, it should be noted that the GX9 is much more recent (by 3 years and 4 months) than the GM5, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the GX9 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Panasonic GX9 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GX9 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Panasonic GM5 are 23 x 17.2 inches or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inches or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inches or 38.9 x 29.2 cm for excellent quality prints.
The Panasonic Lumix DMC-GM5 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The Panasonic Lumix DC-GX9 offers exactly the same ISO settings.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 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 GX9 provides a better video resolution than the GM5. It can shoot movie 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 review are similar with respect to both having an electronic viewfinder. However, the one in the GX9 offers a substantially higher resolution than the one in the GM5 (2760k vs 1166k dots). The table below summarizes some of the other core capabilities of the Panasonic GM5 and Panasonic GX9 in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the GX9 and the GM5 is in-body image stabilization (IBIS). The GX9 reduces the risk of handshake-induced blur with all attached lenses, while the GM5 offers no blur reduction with lenses that themselves do not provide optical image stabilization.
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 GM5 and the Panasonic GX9 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 GM5 and the GX9 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of 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-GM5 and Panasonic Lumix DC-GX9 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The GX9 is a recent model that features in the current product line-up of Panasonic. In contrast, the GM5 has been discontinued (but can be found pre-owned on eBay). There has not been a direct replacement model for the GM5 from Panasonic. 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 how do things add up? Is the Panasonic GM5 better than the Panasonic GX9 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Panasonic Lumix DMC-GM5:

If the number of relative strengths (bullet points above) is taken as a guide, the GX9 is the clear winner of the contest (14 : 5 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 before making a camera decision. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 GM5 and the Panasonic GX9 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the GM5 and the GX9 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 hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 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.
