Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GX85 and the Samsung NX500? 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

An illustration of the physical size and weight of the Panasonic GX85 and the Samsung NX500 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 width, height and depth dimensions are rounded to the nearest millimeter.

The GX85 can be obtained in two different colors (black, silver), while the NX500 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 Samsung NX500 is notably smaller (11 percent) than the Panasonic GX85. Moreover, the NX500 is markedly lighter (33 percent) than the GX85. In this context, it is worth noting that neither the GX85 nor the NX500 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. 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.

The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

The price is, of course, an important factor in any camera decision. 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 two cameras under review were launched at the same price and fall into the same 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.

Sensor comparison

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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic GX85 features a Four Thirds sensor and the Samsung NX500 an APS-C sensor. The sensor area in the NX500 is 64 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the GX85 has a native 4:3 aspect ratio, while the one in the NX500 offers a 3:2 aspect.

With 28MP, the NX500 offers a higher resolution than the GX85 (15.8MP), but the NX500 has smaller individual pixels (pixel pitch of 3.63μm versus 3.77μm for the GX85). It is noteworthy in this context that the GX85 is a somewhat more recent model (by 1 year and 1 month) than the NX500, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. 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 Samsung NX500 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NX500 for good quality output (200 dots per inch) amounts to 32.4 x 21.6 inches or 82.3 x 54.9 cm, for very good quality (250 dpi) 25.9 x 17.3 inches or 65.8 x 43.9 cm, and for excellent quality (300 dpi) 21.6 x 14.4 inches or 54.9 x 36.6 cm. The corresponding values for the Panasonic GX85 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 NX500 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Panasonic Lumix DMC-GX85 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the Samsung NX500 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.

In terms of underlying technology, the GX85 is build around a CMOS sensor, while the NX500 uses a BSI-CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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"). Of the two cameras under consideration, the NX500 offers substantially better image quality than the GX85 (overall score 16 points higher). The advantage is based on 1.9 bits higher color depth, 1.3 EV in additional dynamic range, and 1.1 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-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, and both provide the same movie specifications (4K/30p).

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the GX85 has an electronic viewfinder (2765k dots), which can be very helpful when shooting in bright sunlight. In contrast, the NX500 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Panasonic GX85, the Samsung NX500, and comparable cameras.

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

One feature that differentiates the GX85 and the NX500 is in-body image stabilization (IBIS). The GX85 reduces the risk of handshake-induced blur with all attached lenses, while the NX500 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, the GX85 is one of those camera that have an additional 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 GX85 and the Samsung NX500 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 GX85 and the NX500 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.

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 Panasonic Lumix DMC-GX85 and Samsung NX500 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The GX85 is a recent model that features in the current product line-up of Panasonic. In contrast, the NX500 has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the NX500 from Samsung. Further information on the features and operation of the GX85 and NX500 can be found, respectively, in the Panasonic GX85 Manual (free pdf) or the online Samsung NX500 Manual.

Review summary

So how do things add up? Is the Panasonic GX85 better than the Samsung NX500 or vice versa? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Panasonic Lumix DMC-GX85:

• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• More modern: Is somewhat more recent (announced 1 year and 1 month after the NX500).

Arguments in favor of the Samsung NX500:

• More detail: Has more megapixels (28 vs 15.8MP), which boosts linear resolution by 36%.
• Better image quality: Scores substantially higher (16 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (1.9 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (1.3 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (1.1 stops ISO advantage).
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster shutter: Has higher mechanical shutter speed (1/6000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (9 vs 8 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (120x64mm vs 122x71mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 139g or 33 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (370 versus 290) out of a single battery charge.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More heavily discounted: Has been on the market for longer (launched in February 2015).

If the count of relative strengths (bullet points above) is taken as a measure, the NX500 is the clear winner of the contest (15 : 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 GX85 and the Samsung NX500 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 GX85 or the NX500 perform in practice. 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.

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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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.
