Nikon Z6 II vs Panasonic GM5
The Nikon Z6 II and the Panasonic Lumix DMC-GM5 are two digital cameras that were officially introduced, respectively, in October 2020 and September 2014. Both the Z6 II and the GM5 are mirrorless interchangeable lens cameras that are based on a full frame (Z6 II) and a Four Thirds (GM5) sensor. The Nikon has a resolution of 24.3 megapixels, whereas the Panasonic provides 15.8 MP.
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 Nikon Z6 II and the Panasonic Lumix DMC-GM5? 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 Nikon Z6 II and the Panasonic GM5 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.
The GM5 can be obtained in two different colors (black, silver), while the Z6 II 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 GM5 is considerably smaller (56 percent) than the Nikon Z6 II. Moreover, the GM5 is substantially lighter (70 percent) than the Z6 II. It is worth mentioning in this context that the Z6 II is splash and dust resistant, while the GM5 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
Concerning battery life, the Z6 II gets 410 shots out of its EN-EL15c battery, while the GM5 can take 220 images on a single charge of its DMW-BLH7 power pack. The power pack in the Z6 II can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The GM5 was launched at a markedly lower price (by 63 percent) than the Z6 II, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the imaging sensor is a crucial determinant 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Nikon Z6 II features a full frame sensor and the Panasonic GM5 a Four Thirds sensor. The sensor area in the GM5 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the Z6 II has a native 3:2 aspect ratio, while the one in the GM5 offers a 4:3 aspect.
With 24.3MP, the Z6 II offers a higher resolution than the GM5 (15.8MP), but the Z6 II nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 3.77μm for the GM5) due to its larger sensor. Moreover, the Z6 II is a much more recent model (by 6 years and 1 month) than the GM5, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The resolution advantage of the Nikon Z6 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Z6 II for good quality output (200 dots per inch) amounts to 30.2 x 20.1 inches or 76.8 x 51.1 cm, for very good quality (250 dpi) 24.2 x 16.1 inches or 61.4 x 40.9 cm, and for excellent quality (300 dpi) 20.2 x 13.4 inches or 51.2 x 34.1 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 Z6 II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Nikon Z6 II has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-204800. The corresponding ISO settings for the Panasonic Lumix DMC-GM5 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the Z6 II provides a higher video resolution than the GM5. It can shoot video footage at 4K/60p, while the Panasonic 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 Z6 II offers a substantially higher resolution than the one in the GM5 (3690k vs 1166k dots). The adjacent table lists some of the other core features of the Nikon Z6 II and Panasonic GM5 along with similar information for a selection of comparators.

One feature that is present on the Z6 II, but is missing on the GM5 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
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 Nikon Z6 II and the Panasonic GM5 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.
The Z6 II writes its imaging data to CFexpress or SDXC cards, while the GM5 uses SDXC cards. The Z6 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the GM5 only has one slot. The Z6 II supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the GM5 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 Nikon Z6 II and Panasonic Lumix DMC-GM5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Z6 II has a microphone port, which is missing on the GM5. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
The Z6 II is a recent model that features in the current product line-up of Nikon. 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 Nikon and Panasonic websites.

- More heavily discounted: Has been around for much longer (launched in September 2014).
If the number of relative strengths (bullet points above) is taken as a guide, the Z6 II is the clear winner of the match-up (26 : 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 before making a decision 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 Nikon Z6 II and the Panasonic GM5 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 remains incomplete and does no justice, for example, to the way the Z6 II or the GM5 perform in practice. 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 hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
