Sony RX100 II versus Panasonic G9
The Sony Cyber-shot DSC-RX100 II and the Panasonic Lumix DC-G9 are two digital cameras that were revealed to the public, respectively, in June 2013 and November 2017. The RX100 II is a fixed lens compact, while the G9 is a mirrorless interchangeable lens camera. The cameras are based on an one-inch (RX100 II) and a Four Thirds (G9) sensor. The Sony has a resolution of 20 megapixel, whereas the Panasonic provides 20.2 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.
Body comparison: Sony RX100 II vs Panasonic G9
The physical size and weight of the Sony RX100 II and the Panasonic G9 are illustrated in the side-by-side display below. 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. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the RX100 II – represents 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 Panasonic G9 is considerably larger (125 percent) than the Sony RX100 II. It is noteworthy in this context that the G9 is splash and dust-proof, while the RX100 II does not feature any corresponding weather-sealing.
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 G9 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 G9 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 camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The RX100 II was launched at a lower price than the G9, despite having a lens build 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison: Sony RX100 II vs Panasonic G9
The size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color depth than smaller pixels in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 Sony RX100 II features an one-inch sensor and the Panasonic G9 a Four Thirds sensor. The sensor area in the G9 is 94 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 2.0. The sensor in the RX100 II has a native 3:2 aspect ratio, while the one in the G9 offers a 4:3 aspect.
With 20.2MP, the G9 offers a higher resolution than the RX100 II (20MP), but the G9 nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 2.41μm for the RX100 II) due to its larger sensor. Moreover, the G9 is a much more recent model (by 4 years and 4 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 pixel-units. Coming back to sensor resolution, it should be mentioned that the G9 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
Unlike the RX100 II, the G9 has the capacity to capture high quality composite images (80.6MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
For most 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"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar 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, but the G9 provides a better video resolution than the RX100 II. It can shoot movie footage at 4K/60p, while the Sony is limited to 1080/60p.
Feature comparison: Sony RX100 II vs Panasonic G9
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G9 has an electronic viewfinder (3680k dots), which can be very helpful when shooting in bright sunlight. In contrast, the RX100 II relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Sony RX100 II and Panasonic G9 in connection with corresponding information for a sample of similar cameras.

If the number of relative strengths (bullet points above) is taken as a guide, the G9 is the clear winner of the contest (14 : 8 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 before making a camera decision.
In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the RX100 II or the G9. 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 where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
