Panasonic GX1 vs Sony ZV-1
The Panasonic Lumix DMC-GX1 and the Sony Cyber-shot ZV-1 are two digital cameras that were revealed to the public, respectively, in November 2011 and May 2020. The GX1 is a mirrorless interchangeable lens camera, while the ZV-1 is a fixed lens compact. The cameras are based on a Four Thirds (GX1) and an one-inch (ZV-1) sensor. The Panasonic has a resolution of 15.8 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 DMC-GX1 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 GX1 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 perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.
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 (20 percent) than the Panasonic GX1. In this context, it is worth noting that neither the GX1 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 GX1 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 GX1 and their specifications in the Micro Four Thirds Lens Catalog.
Concerning battery life, the GX1 gets 320 shots out of its DMW-BLD10 battery, while the ZV-1 can take 260 images on a single charge of its NP-BX1 power pack. The power pack in the ZV-1 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.

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. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the sensor inside a digital camera is one of the key determinants 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Panasonic GX1 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 GX1 has a native 4:3 aspect ratio, while the one in the ZV-1 offers a 3:2 aspect.
Despite having a smaller sensor, the ZV-1 offers a higher resolution of 20 megapixels, compared with 15.8 MP of the GX1. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 3.77μm for the GX1). However, it should be noted that the ZV-1 is much more recent (by 8 years and 6 months) than the GX1, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Sony ZV-1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the ZV-1 for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Panasonic GX1 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 Panasonic Lumix DMC-GX1 has a native sensitivity range from ISO 160 to ISO 12800. 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.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the ZV-1 provides a better video resolution than the GX1. It can shoot movie footage at 4K/30p, while the Panasonic is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a variety of features. The GX1 and the ZV-1 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. That said, the GX1 can be equipped with an optional viewfinder – the DMW-LVF2. The adjacent table lists some of the other core features of the Panasonic GX1 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 GX1 has one, while the ZV-1 does not. While the built-in flash of the GX1 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 GX1 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, the ZV-1 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 Sony ZV-1 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 GX1 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 DMC-GX1 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 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the GX1 does not provide wifi capability.
The ZV-1 is a recent model that features in the current product line-up of Sony. In contrast, the GX1 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the GX1 was succeeded by the Panasonic GX7. 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 there a clear favorite between the Panasonic GX1 and the Sony ZV-1? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Panasonic Lumix DMC-GX1:
- More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- Longer lasting: Can take more shots (320 versus 260) on a single battery charge.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More heavily discounted: Has been available for much longer (launched in November 2011).
Advantages of the Sony Cyber-shot ZV-1:
- More detail: Has more megapixels (20 vs 15.8MP), which boosts linear resolution by 15%.
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- Better sound: Can connect to an external microphone for higher quality sound recording.
- More detailed LCD: Has a higher resolution rear screen (922k vs 460k dots).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (24 vs 4.2 flaps/sec) to capture the decisive moment.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Ready to shoot: Has an integrated lens, whereas the GX1 necessitates an extra lens.
- More compact: Is smaller (105x60mm vs 116x68mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the GX1).
- Easier travel charging: Can be conveniently charged via its USB port.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.

- More modern: Reflects 8 years and 6 months of technical progress since the GX1 launch.
If the count of individual advantages (bullet points above) is taken as a guide, the ZV-1 is the clear winner of the contest (18 : 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 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 GX1 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 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 GX1 or the ZV-1 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.
This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
