Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GF6 and the Sony Cyber-shot DSC-RX0? 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 GF6 and the Sony RX0. 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 GF6 can be obtained in four different colors (black, brown, red, white), while the RX0 is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX0 is considerably smaller (66 percent) than the Panasonic GF6. It is noteworthy in this context that the RX0 is splash and dust-proof, while the GF6 does not feature any corresponding weather-sealing. More than that, the RX0 is water-proof up to 10m and can, thus, be used for underwater photography.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX0 has a lens built in, whereas the GF6 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 GF6 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the GF6 gets 340 shots out of its Panasonic DMW-BLG10 battery, while the RX0 can take 240 images on a single charge of its Sony NP-BJ1 power pack. The power pack in the RX0 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. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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 sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 GF6 features a Four Thirds sensor and the Sony RX0 an one-inch sensor. The sensor area in the RX0 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 GF6 has a native 4:3 aspect ratio, while the one in the RX0 offers a 3:2 aspect.

With 15.8MP, the GF6 offers a slightly higher resolution than the RX0 (15.4MP), but the GF6 nevertheless has larger individual pixels (pixel pitch of 3.77μm versus 2.74μm for the RX0) due to its larger sensor. However, the RX0 is a much more recent model (by 4 years and 4 months) than the GF6, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The Panasonic Lumix DMC-GF6 has a native sensitivity range from ISO 160 to ISO 12800, which can be extended to ISO 160-25600. The corresponding ISO settings for the Sony Cyber-shot DSC-RX0 are ISO 125 to ISO 12800 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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 consideration, the RX0 offers substantially better image quality than the GF6 (overall score 14 points higher). The advantage is based on 1.7 bits higher color depth, 1.8 EV in additional dynamic range, and 0.2 stops of reduced low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the RX0 provides a faster frame rate than the GF6. It can shoot movie footage at 1080/60p, while the Panasonic is limited to 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The GF6 and the RX0 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. The table below summarizes some of the other core capabilities of the Panasonic GF6 and Sony RX0 in connection with corresponding information for a sample of similar cameras.

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

One difference between the cameras concerns the presence of an on-board flash. The GF6 has one, while the RX0 does not. While the built-in flash of the GF6 is not very powerful, it can at times be useful as a fill-in light.

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 RX0 only has 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 GF6 writes its imaging data to SDXC cards, while the RX0 uses micro SDXC or Memory Stick Micro 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 Panasonic Lumix DMC-GF6 and Sony Cyber-shot DSC-RX0 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX0 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The GF6 does not feature such a mic input.

Both the GF6 and the RX0 have been discontinued, but can regularly be found used on ebay. The GF6 was replaced by the Panasonic GF7, while the RX0 was followed by the Sony RX0 II. Further information on the features and operation of the GF6 and RX0 can be found, respectively, in the Panasonic GF6 Manual (free pdf) or the online Sony RX0 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Panasonic GF6 and the Sony RX0? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Panasonic Lumix DMC-GF6:

• Larger screen: Has a bigger rear LCD (3.0" vs 1.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• Longer lasting: Can take more shots (340 versus 240) on a single battery charge.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More heavily discounted: Has been available for much longer (launched in April 2013).

Advantages of the Sony Cyber-shot DSC-RX0:

• Better image quality: Scores substantially higher (14 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (1.7 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (1.8 EV of extra DR).
• Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Faster burst: Shoots at higher frequency (5.5 vs 4.2 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Ready to shoot: Has an integrated lens, whereas the GF6 necessitates an extra lens.
• More compact: Is smaller (59x41mm vs 111x65mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the GF6).
• Easier travel charging: Can be conveniently charged via its USB port.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Water-proof: Is rugged and sealed and can thus be used for underwater photography (up to 10m).
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More modern: Reflects 4 years and 4 months of technical progress since the GF6 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the RX0 is the clear winner of the contest (15 : 10 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. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

How about other alternatives? Do the specifications of the Panasonic GF6 and the Sony RX0 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Prime Lens Compact 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the GF6 or the RX0. 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 where reviews by experts come in. 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.

The review scores listed above should be treated with care, 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
