Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon Z50 and the Panasonic Lumix DMC-GX850? 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.

Body comparison

The physical size and weight of the Nikon Z50 and the Panasonic GX850 are illustrated 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 width, height and depth dimensions are rounded to the nearest millimeter.

The GX850 can be obtained in three different colors (black, silver, red), while the Z50 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 GX850 is considerably smaller (42 percent) than the Nikon Z50. Moreover, the GX850 is substantially lighter (40 percent) than the Z50. It is worth mentioning in this context that the Z50 is splash and dust resistant, while the GX850 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 Z50 gets 320 shots out of its Nikon EN-EL25 battery, while the GX850 can take 210 images on a single charge of its Panasonic DMW-BLH7 power pack. The power pack in the Z50 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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 GX850 was launched at a markedly lower price (by 36 percent) than the Z50, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. 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 Z50 features an APS-C sensor and the Panasonic GX850 a Four Thirds sensor. The sensor area in the GX850 is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the Z50 has a native 3:2 aspect ratio, while the one in the GX850 offers a 4:3 aspect.

With 20.7MP, the Z50 offers a higher resolution than the GX850 (15.8MP), but the Z50 nevertheless has larger individual pixels (pixel pitch of 4.22μm versus 3.77μm for the GX850) due to its larger sensor. Moreover, the Z50 is a much more recent model (by 2 years and 9 months) than the GX850, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Nikon Z50 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Z50 for good quality output (200 dots per inch) amounts to 27.8 x 18.6 inches or 70.7 x 47.1 cm, for very good quality (250 dpi) 22.3 x 14.8 inches or 56.6 x 37.7 cm, and for excellent quality (300 dpi) 18.6 x 12.4 inches or 47.1 x 31.4 cm. The corresponding values for the Panasonic GX850 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 Z50 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Nikon Z50 has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 100-204800. The corresponding ISO settings for the Panasonic Lumix DMC-GX850 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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. 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, and both provide the same movie specifications (4K/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the Z50 has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GX850 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Nikon Z50, the Panasonic GX850, and comparable cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

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 Z50 and the Panasonic GX850 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 Z50 and the GX850 write their files to SDXC cards. The Z50 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the GX850 can use UHS-I cards (up to 104 MB/s).

Connectivity comparison

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 Z50 and Panasonic Lumix DMC-GX850 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Z50 has a hotshoe, while the GX850 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

The Z50 is a recent model that features in the current product line-up of Nikon. In contrast, the GX850 has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the GX850 from Panasonic. Further information on the features and operation of the Z50 and GX850 can be found, respectively, in the Nikon Z50 Manual (free pdf) or the online Panasonic GX850 Manual.

Review summary

So how do things add up? Is the Nikon Z50 better than the Panasonic GX850 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Nikon Z50:

• More detail: Offers more megapixels (20.7 vs 15.8MP) with a 17% higher linear resolution.
• Better image quality: Features a larger and more technologically advanced imaging sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/500s) to freeze action.
• Longer lasting: Can take more shots (320 versus 210) on a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.

• Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
• More modern: Reflects 2 years and 9 months of technical progress since the GX850 launch.

Reasons to prefer the Panasonic Lumix DMC-GX850:

• More compact: Is smaller (107x65mm vs 127x94mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 181g or 40 percent) and is thus easier to take along.
• More affordable: Was introduced into a lower priced category (36 percent cheaper at launch).
• More heavily discounted: Has been around for much longer (launched in January 2017).

If the count of relative strengths (bullet points above) is taken as a measure, the Z50 is the clear winner of the match-up (17 : 4 points). 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 when reflecting and deciding 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 Z50 and the Panasonic GX850 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the Z50 or the GX850. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

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], digitalcameraworld [DCW], 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 are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
