Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GX1 and the Sony Cyber-shot DSC-RX100 III? 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

The side-by-side display below illustrates the physical size and weight of the Panasonic GX1 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.

Compare GX1 versus RX100 III top
Comparison GX1 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 notably smaller (25 percent) than the Panasonic GX1. In this context, it is worth noting that neither the GX1 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 GX1 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 GX1 and their specifications in the Micro Four Thirds Lens Catalog.

The power pack in the RX100 III can be charged via the USB port, which can be very convenient when travelling.

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

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

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 Panasonic GX1 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 GX1 has a native 4:3 aspect ratio, while the one in the RX100 III offers a 3:2 aspect.

Panasonic GX1 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 GX1. 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 GX1). However, it should be noted that the RX100 III is much more recent (by 2 years and 6 months) than the GX1, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

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 inch or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inch or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inch or 46.3 x 30.9 cm. The corresponding values for the Panasonic GX1 are 23 x 17.2 inch or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inch or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inch or 38.9 x 29.2 cm for excellent quality prints.

The Panasonic Lumix DMC-GX1 has a native sensitivity range from ISO 160 to ISO 12800. 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.

GX1 versus RX100 III MP

For many 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"). Of the two cameras under consideration, the RX100 III offers substantially better image quality than the GX1 (overall score 12 points higher). The advantage is based on 1.6 bits higher color depth, 1.7 EV in additional dynamic range, and 0.5 stops of reduced low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar 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, and both provide the same movie specifications (1080/60p).

 

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the RX100 III has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GX1 relies on live view and the rear LCD for framing. That said, the GX1 can be equipped with an optional viewfinder – the DMW-LVF2. The table below summarizes some of the other core capabilities of the Panasonic GX1 and Sony RX100 III in connection with corresponding information for a sample of similar cameras.

It is notable that the GX1 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.

Both the GX1 and the RX100 III have been discontinued, but can regularly be found used on eBay. The GX1 was replaced by the Panasonic GX7, while the RX100 III was followed by the Sony RX100 IV. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic and Sony websites.


Review summary

So what is the bottom line? Is there a clear favorite between the Panasonic GX1 and the Sony RX100 III? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Reasons to prefer the Panasonic Lumix DMC-GX1:

  • Better low-light sensitivity: Requires less light for good images (0.5 stops ISO advantage).
  • 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.
  • 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 heavily discounted: Has been available for much longer (launched in November 2011).

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 image quality: Scores substantially higher (12 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.6 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1.7 EV of extra DR).
  • Easier framing: Has an electronic viewfinder for image composition and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 460k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (10 vs 4.2 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has an integrated lens, whereas the GX1 necessitates an extra lens.
  • More compact: Is smaller (102x58mm vs 116x68mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the GX1).
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More modern: Reflects 2 years and 6 months of technical progress since the GX1 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the RX100 III is the clear winner of the contest (16 : 6 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.

GX1 06:16 RX100 III

How about other alternatives? Do the specifications of the Panasonic GX1 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 says little about, for example, the shooting experience and imaging performance of the GX1 and the RX100 III 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 (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.

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

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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
