Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GH2 and the Sony Cyber-shot DSC-RX0II? 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 physical size and weight of the Panasonic GH2 and the Sony RX0 II are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

The GH2 can be obtained in two different colors (black, silver), while the RX0 II 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 II is considerably smaller (78 percent) than the Panasonic GH2. It is noteworthy in this context that the RX0 II is splash and dust-proof, while the GH2 does not feature any corresponding weather-sealing. More than that, the RX0 II 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 II has a lens built in, whereas the GH2 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 GH2 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the GH2 gets 330 shots out of its Panasonic DMW-BLC12 battery, while the RX0 II can take 240 images on a single charge of its Sony NP-BJ1 power pack. The power pack in the RX0 II 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.

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. The RX0 II was launched at a lower price than the GH2, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic GH2 features a Four Thirds sensor and the Sony RX0 II an one-inch sensor. The sensor area in the RX0 II 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 GH2 has a native 4:3 aspect ratio, while the one in the RX0 II offers a 3:2 aspect.

With 15.9MP, the GH2 offers a slightly higher resolution than the RX0 II (15.4MP), but the GH2 nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 2.74μm for the RX0 II) due to its larger sensor. However, the RX0 II is a much more recent model (by 8 years and 6 months) than the GH2, 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-GH2 has a native sensitivity range from ISO 160 to ISO 12800. The corresponding ISO settings for the Sony Cyber-shot DSC-RX0II are ISO 80 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). 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 cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the RX0 II provides a better video resolution than the GH2. It can shoot movie footage at 4K/30p, while the Panasonic is limited to 1080/60i.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the GH2 has an electronic viewfinder (1534k dots), which can be very helpful when shooting in bright sunlight. In contrast, the RX0 II relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Panasonic GH2, the Sony RX0 II, and comparable 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 GH2 has one, while the RX0 II does not. While the built-in flash of the GH2 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 II 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 GH2 writes its imaging data to SDXC cards, while the RX0 II uses micro SDXC or Memory Stick Micro cards. The RX0 II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the GH2 cannot take advantage of Ultra High Speed SD cards.

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-GH2 and Sony Cyber-shot DSC-RX0II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GH2 has a hotshoe, while the RX0 II does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

The RX0 II is a recent model that features in the current product line-up of Sony. In contrast, the GH2 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the GH2 was succeeded by the Panasonic GH3. Further information on the features and operation of the GH2 and RX0 II can be found, respectively, in the Panasonic GH2 Manual (free pdf) or the online Sony RX0 II Manual.

Review summary

So how do things add up? Is the Panasonic GH2 better than the Sony RX0 II or vice versa? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Panasonic Lumix DMC-GH2:

• Easier framing: Has an electronic viewfinder for image composition and settings control.
• 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 (460k vs 230k dots).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• Longer lasting: Can take more shots (330 versus 240) on a single battery charge.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• 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 September 2010).

Reasons to prefer the Sony Cyber-shot DSC-RX0II:

• Better video: Provides higher definition movie capture (4K/30p vs 1080/60i).
• Faster burst: Shoots at higher frequency (5.5 vs 3 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 GH2 necessitates an extra lens.
• More compact: Is smaller (59x41mm vs 124x90mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the GH2).
• 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 file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 8 years and 6 months of technical progress since the GH2 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the RX0 II is the clear winner of the contest (14 : 9 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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.

How about other alternatives? Do the specifications of the Panasonic GH2 and the Sony RX0 II 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 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 GH2 and the RX0 II 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.

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

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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.
