Any camera decision will obviously take relative prices into account. 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 RX100 was launched at a markedly lower price (by 35 percent) than the LX100 II, which puts it into a different market segment. 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. 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 LX100 II features a Four Thirds sensor and the Sony RX100 an one-inch sensor. The sensor area in the RX100 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 LX100 II has a native 4:3 aspect ratio, while the one in the RX100 offers a 3:2 aspect. The LX100 II 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.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
Despite having a smaller sensor, the RX100 offers a higher resolution of 20 megapixels, compared with 16.8 MP of the LX100 II. 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 3.66μm for the LX100 II). Moreover, it should be noted that the LX100 II is much more recent (by 6 years and 2 months) than the RX100, 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 LX100 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Sony RX100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX100 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 LX100 II are 23.7 x 17.8 inches or 60.1 x 45.1 cm for good quality, 18.9 x 14.2 inches or 48.1 x 36.1 cm for very good quality, and 15.8 x 11.8 inches or 40.1 x 30.1 cm for excellent quality prints.
The Panasonic Lumix DC-LX100 II 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 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-25600.
For many cameras, data on sensor performance has been reported by DXO Mark. 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").

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the LX100 II provides a higher video resolution than the RX100. It can shoot video footage at 4K/30p, while the Sony is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the LX100 II has an electronic viewfinder (2764k dots), which can be very helpful when shooting in bright sunlight. In contrast, the RX100 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Panasonic LX100 II and Sony RX100 along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The LX100 II has a touchscreen, while the RX100 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
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 LX100 II 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 LX100 II 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.
Both the LX100 II and the RX100 have zoom lenses built in. The LX100 II has a 24-75mm f/1.7-2.8 optic and the RX100 offers a 28-100mm f/1.8-4.9 (focal lengths in full frame equivalent terms). Hence, the Panasonic provides a wider angle of view at the short end than the Sony, but less tele-photo reach at the long end. The LX100 II offers the faster maximum aperture.
The LX100 II writes its imaging data to SDXC cards, while the RX100 uses SDXC or Memory Stick PRO Duo cards. The LX100 II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the RX100 cannot take advantage of Ultra High Speed SD cards.
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-LX100 II and Sony Cyber-shot DSC-RX100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the LX100 II has a hotshoe, while the RX100 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
The LX100 II is a recent model that features in the current product line-up of Panasonic. In contrast, the RX100 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the RX100 was succeeded by the Sony RX100 II. 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 what is the bottom line? Which of the two cameras – the Panasonic LX100 II or the Sony RX100 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

- More heavily discounted: Has been around for much longer (launched in June 2012).
If the count of relative strengths (bullet points above) is taken as a measure, the LX100 II is the clear winner of the match-up (19 : 8 points). 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 LX100 II and the Sony RX100 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera listing 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 incomplete and does no justice, for example, to the way the LX100 II or the RX100 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 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.

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. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
