Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GX7 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

The physical size and weight of the Panasonic GX7 and the Samsung NX500 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.

The GX7 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 (12 percent) than the Panasonic GX7. Moreover, the NX500 is markedly lighter (29 percent) than the GX7. In this context, it is worth noting that neither the GX7 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 power pack in the NX500 can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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 NX500 was launched at a somewhat lower price (by 20 percent) than the GX7, which makes it more attractive for photographers on a tight budget. 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. 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 GX7 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 GX7 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 GX7 (15.8MP), but the NX500 has smaller individual pixels (pixel pitch of 3.63μm versus 3.77μm for the GX7). Yet, the NX500 is a somewhat more recent model (by 1 year and 6 months) than the GX7, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the NX500 has no anti-alias filter installed, so that it can capture all the detail its 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 GX7 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-GX7 has a native sensitivity range from ISO 125 to ISO 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 GX7 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under consideration, the NX500 offers substantially better image quality than the GX7 (overall score 17 points higher). The advantage is based on 2.2 bits higher color depth, 1.7 EV in additional dynamic range, and 0.9 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the NX500 provides a better video resolution than the GX7. It can shoot movie footage at 4K/30p, while the Panasonic is limited to 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the GX7 has an electronic viewfinder (2760k 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 GX7, 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 GX7 and the NX500 is in-body image stabilization (IBIS). The GX7 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 GX7 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 GX7 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 GX7 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-GX7 and Samsung NX500 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the GX7 and the NX500 have been discontinued, but can regularly be found used on ebay. The GX7 was replaced by the Panasonic GX85, while the NX500 does not have a direct successor. Further information on the features and operation of the GX7 and NX500 can be found, respectively, in the Panasonic GX7 Manual (free pdf) or the online Samsung NX500 Manual.

Review summary

So what is the bottom line? Is the Panasonic GX7 better than the Samsung NX500 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Panasonic Lumix DMC-GX7:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/6000s) to freeze action.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• More heavily discounted: Has been on the market for longer (launched in August 2013).

Reasons to prefer the Samsung NX500:

• More detail: Has more megapixels (28 vs 15.8MP), which boosts linear resolution by 36%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores substantially higher (17 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (2.2 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (1.7 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (0.9 stops ISO advantage).
• Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
• 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 burst: Shoots at higher frequency (9 vs 5 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (120x64mm vs 123x71mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 115g or 29 percent) and is thus easier to take along.
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More affordable: Was released into a lower priced segment (20 percent cheaper at launch).
• More modern: Was introduced somewhat (1 year and 6 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the NX500 is the clear winner of the contest (16 : 6 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 Panasonic GX7 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 GX7 or the NX500 perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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.

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.
