Panasonic GX9 vs Sony ZV-1
The Panasonic Lumix DC-GX9 and the Sony Cyber-shot ZV-1 are two digital cameras that were officially introduced, respectively, in February 2018 and May 2020. The GX9 is a mirrorless interchangeable lens camera, while the ZV-1 is a fixed lens compact. The cameras are based on a Four Thirds (GX9) and an one-inch (ZV-1) sensor. The Panasonic has a resolution of 20.2 megapixels, whereas the Sony provides 20 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 Panasonic Lumix DC-GX9 and the Sony Cyber-shot ZV-1? 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 physical size and weight of the Panasonic GX9 and the Sony ZV-1 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 GX9 can be obtained in two different colors (black, silver), while the ZV-1 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 ZV-1 is notably smaller (29 percent) than the Panasonic GX9. In this context, it is worth noting that neither the GX9 nor the ZV-1 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the ZV-1 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.
The battery packs of both cameras can be charged via USB, 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.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The ZV-1 was launched at a lower price than the GX9, despite having a lens built in. 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 GX9 features a Four Thirds sensor and the Sony ZV-1 an one-inch sensor. The sensor area in the ZV-1 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 ZV-1 offers a 3:2 aspect.
With 20.2MP, the GX9 offers a slightly higher resolution than the ZV-1 (20MP), but the GX9 nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 2.41μm for the ZV-1) due to its larger sensor. However, the ZV-1 is a much more recent model (by 2 years and 3 months) than the GX9, 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 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 ZV-1 are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (4K/30p).
Beyond body and sensor, cameras can and do differ across a range of features. For example, the GX9 has an electronic viewfinder (2760k dots), which can be very helpful when shooting in bright sunlight. In contrast, the ZV-1 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Panasonic GX9 and Sony ZV-1 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The GX9 has one, while the ZV-1 does not. While the built-in flash of the GX9 is not very powerful, it can at times be useful as a fill-in light.The ZV-1 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 and the Sony ZV-1 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 GX9 writes its imaging data to SDXC cards, while the ZV-1 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 ZV-1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the ZV-1 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The GX9 does not feature such a mic input.
Both the GX9 and the ZV-1 are recent models that are part of the current product line-up. The GX9 replaced the earlier Panasonic GX8, while the ZV-1 does not have a direct predecessor. 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? Which of the two cameras – the Panasonic GX9 or the Sony ZV-1 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Panasonic Lumix DC-GX9:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.

- 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 (105x60mm 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 affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Reflects 2 years and 3 months of technical progress since the GX9 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the match-up finishes in a tie (11 points each). 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 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 GX9 and the Sony ZV-1 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 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 GX9 or the ZV-1. 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.
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], 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
