Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DC-GX9 and the Sony Cyber-shot DSC-RX100 V? 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.
The side-by-side display below illustrates the physical size and weight of the Panasonic GX9 and the Sony RX100 V. 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 GX9 can be obtained in two different colors (black, silver), while the RX100 V 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 Sony RX100 V is considerably smaller (34 percent) than the Panasonic GX9. In this context, it is worth noting that neither the GX9 nor the RX100 V are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX100 V has a lens built in, whereas the GX9 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the GX9 and their specifications in the Micro Four Thirds Lens Catalog.
Concerning battery life, the GX9 gets 260 shots out of its DMW-BLG10 battery, while the RX100 V can take 220 images on a single charge of its NP-BX1 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.
(1) Number of images that can be taken on a full battery charge according to the CIPA-standard; (2) Official announcement.
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. 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. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Panasonic GX9 features a Four Thirds sensor and the Sony RX100 V an one-inch sensor. The sensor area in the RX100 V is 48 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 2.7. The sensor in the GX9 has a native 4:3 aspect ratio, while the one in the RX100 V offers a 3:2 aspect.
With 20.2MP, the GX9 offers a slightly higher resolution than the RX100 V (20MP), but the GX9 nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 2.41μm for the RX100 V) due to its larger sensor. Moreover, the GX9 is a somewhat more recent model (by 1 year and 4 months) than the RX100 V, and its sensor might 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 the GX9 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The Panasonic Lumix DC-GX9 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 Sony Cyber-shot DSC-RX100 V are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.
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 also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (4K/30p).
Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the GX9 offers a higher resolution than the one in the RX100 V (2760k vs 2359k dots). The table below summarizes some of the other core capabilities of the Panasonic GX9 and Sony RX100 V in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GX9 has a touchscreen, while the RX100 V has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The RX100 V has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the GX9 does not have a selfie-screen.
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 GX9 has 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 GX9 writes its imaging data to SDXC cards, while the RX100 V uses SDXC or Memory Stick PRO Duo 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 DC-GX9 and Sony Cyber-shot DSC-RX100 V and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GX9 has a hotshoe, while the RX100 V does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the GX9 and the RX100 V are recent models that are part of the current product line-up. The RX100 V replaced the earlier Sony RX100 IV, while the GX9 followed on from the Panasonic GX8. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic and Sony websites.
So how do things add up? Is the Panasonic GX9 better than the Sony RX100 V or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Panasonic Lumix DC-GX9:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- 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.
- More detailed viewfinder: Has higher resolution electronic viewfinder (2760k vs 2359k dots).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.22x).
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- Longer lasting: Can take more shots (260 versus 220) on a single battery charge.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- More modern: Is somewhat more recent (announced 1 year and 4 months after the RX100 V).
Reasons to prefer the Sony Cyber-shot DSC-RX100 V:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (24 vs 9 flaps/sec) to capture the decisive moment.
- Ready to shoot: Has an integrated lens, whereas the GX9 necessitates an extra lens.
- More compact: Is smaller (102x58mm vs 124x72mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the GX9).
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- More heavily discounted: Has been on the market for longer (launched in October 2016).
If the count of relative strengths (bullet points above) is taken as a measure, the GX9 is the clear winner of the match-up (15 : 8 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 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 GX9 and the Sony RX100 V place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Travel-Zoom Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the GX9 or the RX100 V. 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.
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.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
