Panasonic GX800 versus Sony RX100 II
The Panasonic Lumix DMC-GX800 (called Panasonic GX850 in some regions) and the Sony Cyber-shot DSC-RX100 II are two digital cameras that were announced, respectively, in January 2017 and June 2013. The GX800 is a mirrorless interchangeable lens camera, while the RX100 II is a fixed lens compact. The cameras are based on a Four Thirds (GX800) and an one-inch sensor. The Panasonic has a resolution of 15.8 megapixel, whereas the Sony provides 20 MP.
The side-by-side display below illustrates the physical size and weight of the Panasonic GX800 and the Sony RX100 II. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the GX800 – represents the basis or 100 percent across all the size and weight measures).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX100 II is notably smaller (15 percent) than the Panasonic GX800. In this context, it is worth noting that neither the GX800 nor the RX100 II are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX100 II has a lens build in, whereas the GX800 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the GX800 and their specifications in the Micro Four Thirds Lens Catalog.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Panasonic GX800 features a Four Thirds sensor and the Sony RX100 II an one-inch sensor. The sensor area in the RX100 II 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 GX800 has a native 4:3 aspect ratio, while the one in the RX100 II offers a 3:2 aspect.
Despite having a smaller sensor, the RX100 II offers a higher resolution of 20 megapixel, compared with 15.8 MP of the GX800. This megapixel 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 GX800). Moreover, it should be noted that the GX800 is much more recent (by 3 years and 6 months) than the RX100 II, 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 GX800 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GX800 provides a higher video resolution than the RX100 II. 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 range of features. The GX800 and the RX100 II 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. The table below summarizes some of the other core capabilities of the Panasonic GX800 and Sony RX100 II in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The GX800 is a current model that online retailers, such as amazon, will have in stock. In contrast, the RX100 II has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the RX100 II was succeeded by the Sony RX100 III.
So what is the bottom line? Which of the two cameras – the Panasonic GX800 or the Sony RX100 II – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Panasonic Lumix DMC-GX800:
- 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.
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- 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.
- More modern: Reflects 3 years and 6 months of technical progress since the RX100 II launch.
Reasons to prefer the Sony Cyber-shot DSC-RX100 II:
- More detail: Has more megapixels (20 vs 15.8MP), which boosts linear resolution by 15%.
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
- Faster shutter: Has higher mechanical shutter speed (2000/sec vs 500/sec) to freeze action.
- Ready to shoot: Has an integrated lens, whereas the GX800 necessitates an extra lens.
- More compact: Is smaller (102x58mm vs 107x65mm) and will fit more readily into a bag.
- Longer lasting: Gets more shots (350 versus 210) out of a single battery charge.
- More heavily discounted: Has been around for much longer (launched in June 2013).
If the count of relative strengths (bullet points above) is taken as a measure, the RX100 II emerges as the winner of the match-up (8 : 6 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.
In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the GX800 or the RX100 II handle or perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why expert reviews are important. The table below summarizes the assessments of some of the best known camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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. A score, therefore, has to be seen in close connection to the price and market introduction time 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, please note that some of the review sites have changed their methodology and reporting over time.
