Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DC-GX9 and the Panasonic Lumix DMC-LX100? 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 Panasonic LX100. 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.
Both cameras are available in two different colors (black, silver).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic LX100 is notably smaller (15 percent) than the Panasonic GX9. In this context, it is worth noting that neither the GX9 nor the LX100 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the LX100 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 power pack in the GX9 can be charged via the USB port, so that it is not always necessary to take the battery charger along 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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3. The LX100 has the particularity of featuring a switch that allows to toggle between multiple aspect ratios, while maintaining the same field of view and full image resolution.
While the two cameras under review share the same sensor size, the GX9 offers a higher resolution of 20.2 megapixels, compared with 12.7 MP of the LX100. This megapixels advantage translates into a 26 percent gain in linear resolution. On the other hand, these sensor specs imply that the GX9 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 4.21μm for the LX100). In this context, it should be noted, however, that the GX9 is much more recent (by 3 years and 4 months) than the LX100, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. 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 resolution advantage of the Panasonic GX9 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GX9 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inch or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inch or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inch or 43.9 x 32.9 cm. The corresponding values for the Panasonic LX100 are 20.6 x 15.4 inch or 52.2 x 39.2 cm for good quality, 16.4 x 12.4 inch or 41.8 x 31.4 cm for very good quality, and 13.7 x 10.3 inch or 34.8 x 26.1 cm for excellent quality prints.
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 Panasonic Lumix DMC-LX100 offers exactly the same ISO settings.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 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 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).
Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the LX100 offers a slightly higher resolution than the one in the GX9 (2764k vs 2760k dots). The adjacent table lists some of the other core features of the Panasonic GX9 and Panasonic LX100 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 LX100 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 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 Panasonic LX100 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 GX9 and the LX100 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.
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 Panasonic Lumix DMC-LX100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the GX9 and the LX100 are recent models that are part of the current product line-up. The GX9 replaced the earlier Panasonic GX8, while the LX100 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 website.
So what conclusions can be drawn? Is there a clear favorite between the Panasonic GX9 and the Panasonic LX100? Which camera is better? The listing below highlights the relative strengths of the two models.
Advantages of the Panasonic Lumix DC-GX9:
- More detail: Offers more megapixels (20.2 vs 12.7MP) with a 26% higher linear resolution.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- More detailed LCD: Has a higher resolution rear screen (1240k vs 921k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- Easier travel charging: Can be conveniently charged via its USB port.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- More modern: Reflects 3 years and 4 months of technical progress since the LX100 launch.
Arguments in favor of the Panasonic Lumix DMC-LX100:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
- Faster burst: Shoots at higher frequency (11 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 (115x66mm 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).
- Longer lasting: Gets more shots (300 versus 260) out of a single battery charge.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- More heavily discounted: Has been around for much longer (launched in September 2014).
If the number of relative strengths (bullet points above) is taken as a guide, the match-up finishes in a tie (9 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 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 Panasonic LX100 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the GX9 or the LX100. 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 where reviews by experts come in. 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 were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price 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.
