Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Cyber-shot DSC-RX100 II and the Panasonic Lumix DMC-GX8? 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.

Body comparison: Sony RX100 II vs Panasonic GX8

The side-by-side display below illustrates the physical size and weight of the Sony RX100 II and the Panasonic GX8. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

The GX8 can be obtained in two different colors (black, silver), while the RX100 II is only available in black.

Comparison RX100 II or GX8 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GX8 is considerably larger (75 percent) than the Sony RX100 II. It is noteworthy in this context that the GX8 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 built in, whereas the GX8 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 GX8 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the RX100 II gets 350 shots out of its NP-BX1 battery, while the GX8 can take 330 images on a single charge of its DMW-BLC12 power pack. The power pack in the RX100 II can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

Any camera decision will naturally be influenced heavily by the price. 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 II was launched at a lower price than the GX8, despite having a lens built 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.

 

Sensor comparison: Sony RX100 II vs Panasonic GX8

The size of the sensor inside a digital camera is one of the key determinants 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.

Of the two cameras under consideration, the Sony RX100 II features an one-inch sensor and the Panasonic GX8 a Four Thirds sensor. The sensor area in the GX8 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 GX8 offers a 4:3 aspect.

Sony RX100 II and Panasonic GX8 sensor measures

With 20.2MP, the GX8 offers a higher resolution than the RX100 II (20MP), but the GX8 nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 2.41μm for the RX100 II) due to its larger sensor. Moreover, the GX8 is a much more recent model (by 2 years) 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.

The Sony Cyber-shot DSC-RX100 II has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Panasonic Lumix DMC-GX8 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

RX100 II versus GX8 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). Of the two cameras under consideration, the GX8 has a markedly higher DXO score than the RX100 II (overall score 8 points higher), which will translate into better image quality. The advantage is based on 1 bits higher color depth, 0.2 EV in additional dynamic range, and 0.7 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-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 GX8 provides a better video resolution than the RX100 II. It can shoot movie footage at 4K/30p, while the Sony is limited to 1080/60p.

 

Feature comparison: Sony RX100 II vs Panasonic GX8

Apart from body and sensor, cameras can and do differ across a range of features. For example, the GX8 has an electronic viewfinder (2360k 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. That said, the RX100 II can be equipped with an optional viewfinder – the FDA-EV1MK. The table below summarizes some of the other core capabilities of the Sony RX100 II and Panasonic GX8 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The RX100 II has one, while the GX8 does not. While the built-in flash of the RX100 II is not very powerful, it can at times be useful as a fill-in light.

The GX8 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 RX100 II 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 GX8 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 GX8 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 RX100 II writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the GX8 uses SDXC cards. The GX8 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the RX100 II cannot take advantage of Ultra High Speed SD cards.

 

Connectivity comparison: Sony RX100 II vs Panasonic GX8

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 Sony Cyber-shot DSC-RX100 II and Panasonic Lumix DMC-GX8 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GX8 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The RX100 II does not feature such a mic input.

Both the RX100 II and the GX8 have been discontinued, but can regularly be found used on eBay. The RX100 II was replaced by the Sony RX100 III, while the GX8 was followed by the Panasonic GX9. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Sony and Panasonic websites.


Review summary: Sony RX100 II vs Panasonic GX8

So how do things add up? Is the Sony RX100 II better than the Panasonic GX8 or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Advantages of the Sony Cyber-shot DSC-RX100 II:

  • More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
  • Ready to shoot: Has a lens built-in, whereas the GX8 requires a separate lens.

  • 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.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More heavily discounted: Has been available for much longer (launched in June 2013).

ilogo

Reasons to prefer the Panasonic Lumix DMC-GX8:

  • Better image quality: Scores markedly higher (8 points) in the DXO overall evaluation.
  • Better low-light sensitivity: Can shoot in dim conditions (0.7 stops ISO advantage).
  • 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.
  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Reflects 2 years of technical progress since the RX100 II launch.

If the count of individual advantages (bullet points above) is taken as a guide, the GX8 is the clear winner of the contest (15 : 7 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 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.

RX100 II 07:15 GX8

How about other alternatives? Do the specifications of the Sony RX100 II and the Panasonic GX8 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Mirrorless Interchangeable Lens 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 says little about, for example, the shooting experience and imaging performance of the RX100 II and the GX8 in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews: Sony RX100 II vs Panasonic GX8

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.
