Body comparison

The side-by-side display below illustrates the physical size and weight of the Sony RX10 III 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 RX10 III is only available in black.

Compare RX10 III versus GX8 top
Comparison RX10 III 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 notably smaller (17 percent) than the Sony RX10 III. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX10 III 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 RX10 III gets 420 shots out of its Sony NP-FW50 battery, while the GX8 can take 330 images on a single charge of its Panasonic DMW-BLC12 power pack. The power pack in the RX10 III can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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. 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

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 RX10 III 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 RX10 III has a native 3:2 aspect ratio, while the one in the GX8 offers a 4:3 aspect.

Sony RX10 III and Panasonic GX8 sensor measures

With 20.2MP, the GX8 offers a higher resolution than the RX10 III (20MP), but the GX8 nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 2.41μm for the RX10 III) due to its larger sensor. However, the RX10 III is a somewhat more recent model (by 8 months) than the GX8, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The Sony Cyber-shot DSC-RX10 III has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 64-25600. 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.

In terms of underlying technology, the RX10 III is build around a BSI-CMOS sensor, while the GX8 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

RX10 III 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 RX10 III (overall score 5 points higher), which will translate into better image quality. The advantage is based on 0.4 bits higher color depth, and 0.8 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The RX10 III has one, while the GX8 does not. While the built-in flash of the RX10 III 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 RX10 III 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, 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 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 RX10 III writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the GX8 uses SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

Connectivity comparison

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-RX10 III and Panasonic Lumix DMC-GX8 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Review summary

So what is the bottom line? Is there a clear favorite between the Sony RX10 III and the Panasonic GX8? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Reasons to prefer the Sony Cyber-shot DSC-RX10 III:

  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
  • Faster burst: Shoots at higher frequency (14 vs 10 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has a lens built-in, whereas the GX8 requires a separate lens.
  • Longer lasting: Can take more shots (420 versus 330) on a single battery charge.
  • 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 modern: Is somewhat more recent (announced 8 months after the GX8).

ilogo

Advantages of the Panasonic Lumix DMC-GX8:

  • Better image quality: Scores markedly higher (5 points) in the DXO overall evaluation.
  • Better low-light sensitivity: Can shoot in dim conditions (0.8 stops ISO advantage).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.77x vs 0.70x).
  • More flexible LCD: Has a 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.
  • 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.
  • More compact: Is smaller (133x78mm vs 133x94mm) and will fit more readily into a bag.
  • More heavily discounted: Has been on the market for longer (launched in July 2015).

If the count of relative strengths (bullet points above) is taken as a measure, the GX8 emerges as the winner of the match-up (11 : 9 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.

RX10 III 09:11 GX8

How about other alternatives? Do the specifications of the Sony RX10 III and the Panasonic GX8 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the RX10 III and the GX8 in practical situations. 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.

Expert reviews

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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.
