Panasonic GX85 vs Sony RX100 III

The Panasonic Lumix DMC-GX85 (called Panasonic GX80 in some regions) and the Sony Cyber-shot DSC-RX100 III are two digital cameras that were revealed to the public, respectively, in April 2016 and May 2014. The GX85 is a mirrorless interchangeable lens camera, while the RX100 III is a fixed lens compact. The cameras are based on a Four Thirds (GX85) and an one-inch (RX100 III) sensor. The Panasonic has a resolution of 15.8 megapixels, whereas the Sony provides 20 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Panasonic GX85 and the Sony RX100 III. 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 GX85 can be obtained in two different colors (black, silver), while the RX100 III is only available in black.

Compare GX85 versus RX100 III top
Comparison GX85 or RX100 III rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX100 III is considerably smaller (32 percent) than the Panasonic GX85. In this context, it is worth noting that neither the GX85 nor the RX100 III are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX100 III has a lens built in, whereas the GX85 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 GX85 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the GX85 gets 290 shots out of its Panasonic DMW-BLG10 battery, while the RX100 III can take 320 images on a single charge of its Sony NP-BX1 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. The listed launch 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.

Sensor comparison

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. 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 Panasonic GX85 features a Four Thirds sensor and the Sony RX100 III an one-inch sensor. The sensor area in the RX100 III 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 GX85 has a native 4:3 aspect ratio, while the one in the RX100 III offers a 3:2 aspect.

Panasonic GX85 and Sony RX100 III sensor measures

Despite having a smaller sensor, the RX100 III offers a higher resolution of 20 megapixels, compared with 15.8 MP of the GX85. 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 3.77μm for the GX85). Moreover, it should be noted that the GX85 is a somewhat more recent model (by 1 year and 10 months) than the RX100 III, and its sensor might 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 GX85 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony RX100 III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX100 III 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 GX85 are 23 x 17.2 inches or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inches or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inches or 38.9 x 29.2 cm for excellent quality prints.

The Panasonic Lumix DMC-GX85 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 III are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 80-25600.

In terms of underlying technology, the GX85 is build around a CMOS sensor, while the RX100 III uses a BSI-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.

GX85 versus RX100 III MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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. Of the two cameras under review, the GX85 has a notably higher overall DXO score than the RX100 III (overall score 4 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.5 bits higher color depth, 0.3 EV in additional dynamic range, and 0.4 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.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GX85 has a touchscreen, while the RX100 III has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The RX100 III 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 GX85 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 GX85 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 GX85 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 GX85 writes its imaging data to SDXC cards, while the RX100 III uses SDXC or Memory Stick PRO Duo cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

It is notable that the GX85 has a hotshoe, while the RX100 III does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

The GX85 is a recent model that features in the current product line-up of Panasonic. In contrast, the RX100 III has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the RX100 III was succeeded by the Sony RX100 IV. Further information on the features and operation of the GX85 and RX100 III can be found, respectively, in the Panasonic GX85 Manual (free pdf) or the online Sony RX100 III Manual.

Review summary

So what is the bottom line? Is the Panasonic GX85 better than the Sony RX100 III or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Arguments in favor of the Panasonic Lumix DMC-GX85:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
  • Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2765k vs 1440k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.59x).
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster shutter: Has higher mechanical shutter speed (1/4000s 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: Accepts interchangeable lenses, so that lens characteristics can be altered.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • More modern: Is somewhat more recent (announced 1 year and 10 months after the RX100 III).

ilogo

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

  • 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).
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (10 vs 8 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has an integrated lens, whereas the GX85 necessitates an extra lens.
  • More compact: Is smaller (102x58mm vs 122x71mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the GX85).
  • Longer lasting: Gets more shots (320 versus 290) out of a single battery charge.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More heavily discounted: Has been on the market for longer (launched in May 2014).

If the count of relative strengths (bullet points above) is taken as a measure, the GX85 emerges as the winner of the contest (13 : 11 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.

GX85 13:11 RX100 III

How about other alternatives? Do the specifications of the Panasonic GX85 and the Sony RX100 III place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Travel-Zoom 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 remains incomplete and does no justice, for example, to the way the GX85 or the RX100 III perform in practice. 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

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
